Network monitoring is of paramount importance to both network operators and researchers, to the point that it has recently become a major research area. However, network monitoring still suffers from fundamental problems that leave its rigorousness behind more traditional research fields, such as other experimental disciplines within physics or biology. Most scientific works in the field of network monitoring are evaluated using private, undisclosed data sets. Nevertheless, disclosure of experimental data is a basic principle of the scientific method that enables experiment reproducibility, independent validation and cross-comparison of research results. For this reason, we think that the credibility of research works in this area overly relies on the scientific community bona fide. Our initial hypothesis is that two fundamental barriers have to be overcome in order to increase the rigorousness of this scientific area. First, the mere acquisition of reference data sets is extremely challenging from a technological viewpoint due to the ever-increasing network speeds. Second, sociological reasons discourage their publication, primarily due to privacy concerns. Both the technological and sociological barriers are currently perceived to be insurmountable, which prevents the use of common data sets in scientific works and impedes experiment reproducibility. The main objective of this project is to investigate the fundamental research challenges associated to these two barriers. On the one hand, this project will explore novel network monitoring and traffic measurement techniques in order to address the technological difficulties. Main topics of research in this direction will include complex resource management techniques, such as load shedding and distribution, traffic sampling and specialized streaming algorithms for traffic processing and analysis. On the other hand, this project will propose a novel data sharing paradigm that overcomes the sociological barriers. The research carried out in this project will result in a completely novel evaluation framework for network monitoring research based on what we call the “code-to-the-data” model. This model will enable reproducibility, validation and comparison of scientific works without requiring full disclosure of traffic data sets, thus avoiding most privacy concerns involved in dataset publication. Ultimately, the new monitoring and data sharing paradigm resulting from this project will provide a realistic solution to set the use of common data sets as a standard requirement for scientific publication, as it is in other research areas.

Mobility is unnatural to today’s Internet architecture, primarily due to overloaded IP address semantics. Several schemes address this issue by decoupling the location of an endpoint from its identity. Such location/identity separation inherently provides services fundamental to the future Internet including seamless mobility, multihoming, and traffic engineering. Of the various location/identity separation schemes, the Location/ID Separation Protocol (LISP) (proposed by Cisco Systems Inc., and under standardization at IETF) has a unique position: LISP is incrementally deployable, it does not require changes to transport/application implementations, and it is already under active deployment (see http://www.lisp4.net). Basically, LISP proposes two different types of addresses: Endpoint Identifiers (EIDs) and Routing Locators (RLOCs). EIDs identify hosts, and are assigned independently of the network topology while RLOCs identify network attachment points, and are used for routing. This allows EIDs to remain unchanged even if a topological change, such as a handover, occurs. Thus, LISP’s innate support for location/identity separation makes LISP well suited for mobility. Indeed, the LISP mobility protocol (LISP-MN) has been recently proposed. LISP-MN offers many advantages in front of traditional mobility schemes such as Mobile IP. On the one hand LISP´s separation of control and data planes avoids mobility provider lock-in, and LISP-MN clients can freely roam among providers (usually ISPs). On the other hand, LISP-MN provides native support for multihoming, load balancing and route optimization, this are important aspects for the future mobile clients. However and traditionally, the Internet architecture has evolved independently of cellular networks (3GPP). Nowadays these cellular networks are converging to an all-IP network, and their new architecture must be gracefully accommodated in the future Internet architecture. This imposes a set of important challenges. In this context, we expect that LISP-MN will play a crucial role. LISP-MN provides a higher level of mobility (at the network layer) and mobile clients can freely roam across providers. The main objectives of the NAME project are (i) Research coherent architectures for the future converged cellular and Internet networks and (ii) Research and design advanced services such as content distribution and live streaming for LISP-MN.

In the current Internet typically live video streaming services operate at the application layer (e.g, P2P Live) and not at the network layer. The main reason for this is that multicast is not widely available in core-routers due to its high deployment and operational costs. In this project we aim to develop Lcast, a new multicast protocol that takes advantage of LISP, and therefore avoids deployment in these core-routers.

The DOMINO project aims at designing novel architecture, algorithms and protocols solutions fulfilling the energy efficiency and awareness requirements of future multi-layer green optical networks. DOMINO leverages the capacities of ultra high dynamic multi-layer optical networks to decrease the ICTs carbon footprint, and relies on five innovative concepts: a thorough analysis of the energetic issues in networks, including the benefits of using novel sub-wavelength switching devices and extending the energy-oriented model to multi-domain scenario; novel network planning strategies accounting for energy, cost and performance metrics; specialised dynamic routing algorithms where multiple constraints such as energy consumption, resource utilisation, and signal quality are optimised; energy-oriented operations and protocols in the network control plane to support the designed strategies and algorithms; dedicated techno-economic studies to evaluate the overall impact the novel concepts have on current network infrastructure and provide a possible migration roadmap.

The EULER project is a 3-year STREP Project targeting Challenge 1 "Technologies and systems architectures for the Future Internet" of the Seventh Framework Programme (FP7). The project scope lies within the Objective ICT-2009.1.6 part b: “Future Internet experimentally-driven research”. The main objective of the EULER exploratory research project is to investigate new routing paradigms so as to design, develop, and validate experimentally a distributed and dynamic routing scheme suitable for the future Internet and its evolution. The resulting routing scheme(s) is/are intended to address the fundamental limits of current stretch-1 shortest-path routing in terms of routing table scalability but also topology and policy dynamics (perform efficiently under dynamic network conditions). Therefore, this project will investigate trade-offs between routing table size (to enhance scalability), routing scheme stretch (to ensure routing quality) and communication cost (to efficiently and timely react to various failures). The driving idea of this research project is to make use of the structural and statistical properties of the Internet topology (some of which are hidden) as well as the stability and convergence properties of the Internet policy in order to specialize the design of a distributed routing scheme known to perform efficiently under dynamic network and policy conditions when these properties are met. The project will develop new models and tools to exhaustively analyse the Internet topology, to accurately and reliably measure its properties, and to precisely characterize its evolution. These models, that will better reflect the network and its policy dynamics, will be used to derive useful properties and metrics for the routing schemes and provide relevant experimental scenarios. The project will develop appropriate tools to evaluate the performance of the proposed routing schemes on large-scale topologies (order of 10k nodes). Prototype of the routing protocols as well as their functional validation and performance benchmarking on the iLAB experimental facility and/or virtual experimental facilities such as PlanetLab/OneLab will allow validating under realistic conditions the overall behaviour of the proposed routing schemes.

STRONGEST’s main goal is to design and demonstrate an evolutionary ultra-high capacity multilayer transport network, based on optimized integration of Optical and Packet nodes, and equipped with a multi-domain, multi-technology control plane, overcoming the problems of current networks that still provide limited scalability, are not cost-effective and do not properly guarantee end-to-end quality of service. STRONGEST is an industry led project; the consortium brings together major European industrial players, leading Telecom operators, Universities and Research Centres and as such, it enables the necessary synergies and creates an ideal environment for innovation and development. The European scale of the project is made necessary by the development of a new reality in which countries and federations are immensely and inextricably linked. To have a common view at European level is essential to apply the project’s outcomes. A major impact from STRONGEST will be to strengthen the position of European industry in the field of Future Internet and to reinforce European leadership in optical networks technologies. The design of a more efficient transport network with reduced cost per bit and the particular attention to energy efficiency will turn into benefit to the entire Community.

This COST Action will propose realistic energy-efficient alternate solutions to share IT distributed resources. As large scale distributed systems gather and share more and more computing nodes and Storage resources, their energy consumption is exponentially increasing. While much effort is nowadays put into hardware specific solutions to lower energy consumptions, the need for a complementary approach is necessary at the distributed system level, i.e. middleware, network and applications. The Action will characterize the energy consumption and energy efficiencies of distributed applications. Then based on the current hardware adaptation possibilities and innovative algorithms it will propose adaptive and alternative approaches taking into account the energy saving dimension of the problem. The Action will characterize the trade-off between energy savings and functional and non-functional parameters, including the economic dimension. A COST Action is the right scheme in order to unite a dispersed community and to promote the dissemination of the solutions and the energy concerns to the broader public. Deliverables will include workshop proceedings, books, good practice leaflets fostering consciousness rise at ICT researchers, scientists, managers and users levels. Finally, benefits will address scientific and societal needs.

Internet, considered as a system, has experienced an unforeseen growth and many local solutions (new applications and protocols and protocol enhancements) have been added. Each solution or protocol intends to solve a problem but independently of other enhancements and protocols. Each of the technologies has been designed as a standalone process not taking into account the inter-dependencies with other ones. Thus, despite the system is flexible enough scalability and performance issues are pushing it to its limits. The main goal of this project is to contribute in the design of technologies for a converged and pervasive Internet. The project aims to push new services and protocols into the network considering them as coupled processes. To do that, we will take into consideration four of the most relevant aspects that are currently of interest of the research community in this field. These are the optical transport, the ubiquitous connectivity, the application of a traffic analysis and monitoring techniques for the management and control of the network, and the security of communications. In order to address these aspects the project is structured in the following research activities: Architectures for the Pervasive Networking, Traffic monitoring and analysis, Converged Optical Networking Infrastructure, and Digital Identity and Electronic Signature, which coincide with of the different subareas of expertise of the Broadband Communication Systems research group that traditionally have exploited participating in separated projects. In this way, an additional benefit of the project will be the integration of these subareas increasing the consistence of the group.
The COST Action IC0703 “Data Traffic Monitoring and Analysis (TMA): theory, techniques, tools and applications for the future networks” was started on March 2008, with a planned duration of 4 years. It is part of the COST programme (ICT domain) which is now run by the European Science Foundation. The high-level goal is to build up a community of researchers working on TMA topics. Besides the official MC delegates, it includes a Chair (Dr. Fabio Ricciato), a Vice-chair (Prof. Jordi Domingo-Pascual, UPC) and a Secretary (Dr. Alessandro D’Alconzo, FTW).

The BONE-proposal builds on the foundations laid out by the e-Photon/ONe projects in the previous Framework Programme. This Network of Excellence has successfully brought together over several years the research activities within Europe in the field of Optical Networks. The BONE-project intends to validate this effort by stimulating a more intensified collaboration, exchange of researchers and building on Virtual Centres of Excellence that can serve to European industry with education & training, research tools & testlabs and pave the way to new technologies & architectures. The Network of the Future, which is the central theme of this Call, will have to cope with a wide variety of applications running on a wide variety of terminals and with an increasing number of connected devices and increasing speed and data-loads. Within this context, issues as convergence between mobile and fixed networks, or issues regarding the optimised broadband access in the last mile using a wide variety of technologies such as DSL, cable, WiMAX, WiFi, PLC, are currently under investigation to adapt the current network to these increasing requirements for better performance. The BONE-proposal looks further into the future and builds the final Network of the Future: - a high capacity, flexible, reconfigurable and self-healing optical Core & Metro network which supports the transport of massive amounts of data - a FTTx solution in which the x is as close as possible to the home, at the home, or even in the home. From this point the user is connected using terminal-specific technologies (wireless to handheld devices, fiber to home cinema, wireless to laptop, fixed connection to desktop, ) - BONE clearly identifies the existence of the current technologies and also recognizes the fact that users also require the mobility of wireless access, but this mobile connection ends at a gateway or access points and from there a fixed connection is required and this fixed connection will finally be an optical link.

Monitoring and mining real-time network data streams is crucial for managing and operating data networks. The information that network operators desire to extract from the network traffic is of different size, granularity and accuracy depending on the measurement task (e.g., relevant data for capacity planning and intrusion detection are very different). To satisfy these different demands, a new class of monitoring systems is emerging to handle multiple arbitrary and continuous traffic queries. Such systems must cope with the effects of overload situations due to the large volumes, high data rates and bursty nature of the network traffic. This project presents the design and evaluation of a system that can shed excess load in the presence of extreme traffic conditions, while maintaining the accuracy of the traffic queries within acceptable levels. The main novelty of our approach is that it is able to operate without explicit knowledge of the traffic queries. Instead, it extracts a set of features from the traffic streams to build an on-line predictionmodel of the query resource requirements. This way the monitoring system preserves a high degree of flexibility, increasing the range of applications and network scenarios where it can be used. We implemented our scheme in an existing network monitoring system and deployed it in a research ISP network. Our results show that the system predicts the resources required to run each traffic query with errors below 5%, and that it can efficiently handle extreme load situations, preventing uncontrolled packet losses, with minimum impact on the accuracy of the queries results.

We aim to design the fundamental building block of a network monitoring infrastructure that allows researchers and network operators to process and share network data across multiple sites. CoMo supports i) arbitrary traffic queries that run continuously on the live data streams, ii) retrospective queries that analyze past traffic data to enable network forensics.
Data streams may have different formats (e.g., packet sequences, flow summaries, etc.) and originate from different platforms (e.g, passive link monitors, routers, wireless access points, etc.). CoMo can operate in the presence of different devices and data sources and provide a unified data interface to queries. Multiple CoMo systems will also cooperate to rapidly disseminate queries throughout the network of monitors, allowing operators to "drill down" to relevant data locations in the network.

UPC-CBA is part of the Archipelago measurement infrastructure. The primary goals of Archipelago (Ark) are to achieve greater scalability and flexibility than our current measurement infrastructure and to provide a step toward a community-oriented measurement infrastructure by eventually allowing collaborators to run their vetted measurement tasks on a security-hardened distributed platform. Ark is tailored specifically for network measurement, which allows it to be simpler and to more directly address the needs of network researchers than is usually the case with a general-purpose distributed experimental platform. The initial and primary focus of Ark is to continue the large-scale traceroute-based active measurements of the skitter infrastructure. In both role and implementation, Ark subsumes the skitter infrastructure and represents a natural evolution. Ark will evolve from the skitter infrastructure by a gradual process in which pieces of the former infrastructure are extended, enhanced, and/or replaced.

As networks get faster and network-centric applications get more complex, our understanding of the Internet continues to diminish. New aspects of Internet behaviour emerge that are either unknown or poorly understood. Denial-of-service attacks, malicious self-replicating programs (worms) and viruses plague the Internet. All these indicate the need for better Internet traffic monitoring. Network monitoring and measurement is increasingly regarded as an essential function for developing and supporting high-quality network services, building and improving innovative networking technologies, analyzing infrastracture trends and user behavior and improving the security of our cyber-infrastracture. LOBSTER is a step towards providing an advanced pilot European passive Internet traffic monitoring infrastracture that will improve our understanding of the Internet and will contribute towards solving difficult performance and security problems. Based on appropriate abstractions and willing cooperation among points of presence, this proposal will contribute towards effectively monitoring the underlying network, providing early warning for security incidents, and providing accurate and meaningful measurements of performance. The main goal of LOBSTER is to deploy an advanced pilot European Internet Traffic Monitoring Infrastracture based on passive monitoring sensors at speeds starting from 2.5 Gbps and possibly up to 10 Gbps. It also aims to develop appropriate data anonymising tools to prohibit unauthorised tampering with the original traffic data, and to develop novel applications to improve monitoring (such as traffic characterisation and zero-day worm spread detection). Another aspect will be to provide anonymised traffic data to interested network researchers and security analysts.

The Network of Excellence e-Photon/ONe+ aims at integrating and focusing the rich know-how available in Europe on optical communication and networks, both in universities and in research centres of major telecom manufacturers and operators. This project built upon the experience gained within the previous NoE e-Photon/ONe, funded within the 1st IST call of FP6. The set of expertises available in the NoE ranges from optical technologies to networking devices, network architectures and protocols, new services fostered by photonic technologies. The NoE contributes to the Strategic Objective 'Broadband for All', with specific focus on low cost access and edge network equipment, for a range of technologies, including optical fiber, on new concepts for network management, control and protocols, and on increased bandwidth capacity, in the access network as well in the underlying optical core/metro network, including in particular optical burst and packet switching. The main technical aim of the e-Photon/ONe+ is to demonstrate and spread awareness of the potential advantages of optical technologies with respect to electronic technologies in both telecom networks and customer-controlled grids. The focus includes both incrementally improving and emerging optical technologies. In a joint effort, the participants to the NoE will work towards a consensus on the engineering choices for the deployment of cost-effective optical technologies as the foundation for the future Internet, with the strong intention to provide valuable inputs to the standardization bodies and guidelines to the operators, as well as competitive feedback to European telecom equipment manufacturers. Integration is pursued primarily by establishing long-term collaborations among partners in terms of research, of infrastructures sharing, and of education and training. The NoE provides the platform within which the main instruments to achieve these long-lasting collaborations, such as the regular exchange of researchers between partners, the involvement in coordinated research activities, and the development of joint teaching programs and events, will be effectively deployed. Dissemination is pursued by means of coordinated publication activities, of training programs implementation, of technical events and workshop organization, and of interaction with other consortia in the same technical area. Although research activities is mainly be carried out in research programs funded externally to the NoE, at both national and European levels, well-focused joint research programs will be activated and implemented internally to the NoE.
e-Photon/ONe+ involves 40 partners, coming from 14 member states (Austria, Belgium, Denmark, France, Germany, Greece, Hungary, Italy, Netherlands, Spain, Sweden, Poland, Portugal, United Kingdom), 2 candidate countries (Croatia, Turkey) and an associated country (Norway). The consortium is composed by 30 universities and other higher education institutes, 3 telecom operators, 3 manufacturers, 4 non-profit research centres.

Leveraging all results obtained in phase 1, NOBEL phase 2 will consider the medium-term, long-term and extended long-term scenarios, focusing in particular on the last two, and will face with two major challenges. The first is the evolution of the data plane technology in order to reach an 'optimum techno-economic balance' between optical/electrical and circuit/packet routing and switching. The second is the evolution of the network control plane towards an unified control plane that is able of improving the seamless end-to-end network service capabilities in a flexible and scalable way. Moreover, NOBEL phase 2 will consider the opportunity deriving from the convergence of fixed and mobile services, analysing its impact on the metro and core parts of the network. To achieve the overall goals of NOBEL phase 2, the following main objectives were identified.
# Definition and demonstration of architectures for providing packet switched and circuit switched connections in an integrated network scenario. Identification of requirements and solutions for the core and metro networks supporting both fixed and mobile services.
# Study and evaluation of multi-layer traffic engineering and resilience schemes in different service and business scenarios to achieve cost-effective solutions.

The purpose of the CATARO project (a coordinated project for the evaluation o optical networks technologies and architectures) is to continue the studies carried out in two previous projects, namely TRIPODE (IP traffic transport over Optical networks: Designing and Evaluation, Ref.: TIC2002-04344-C02) and CARISMA (Connection and access to RedIRIS2 through a multi-channel optical ring, CICYT TIC2000-0304-P4-04). Thereby, the CATARO project consists of two subprojects, namely SENDERO (Designing and Evaluation of optical network architectures Ref.: TEC2005-08051-C3-01) and RINGING (GMPLS/ASON Intelligent Network: Integration of reconfigurable nodes, Ref.: TEC2005-08051-C3-02), which are summarized next.
The SENDERO subproject basically concerns the analysis aspects, design and performance evaluation of the network architectures based on optical technology having as objectives, on the one hand completing the subjects opened after finalization the TRIPODE project and on the other hand opening new topics, which interest is growing. Particularly, with respect to optical network architectures that could potentially be implemented in a short-term, it will continue working on control plane and routing algorithms for ASON (Automatically Switched Optical Networks) as well as will begin new topics like provisioning of new telecommunication services, which is required by emerging applications like Grid Computing and Storage Area Networks and inter-working the RPR (Resilience Packet Rings) with ASON networks. Regarding mediumterm architectures, the subproject will continue the subject of metropolitan area optical networks taking into consideration possible implementations of the first prototypes in public infrastructures and evaluation of the architectures more sophisticated. However, the principal objective of this block will be centred on the optical burst switching networks (OBS), the architecture which is gaining interest thanks to its both foreseeable strong benefits and future technological affordability. Finally, in the context of long-term network architectures, the subproject will continue the study on OPS (Optical Packet Switching) nodes functionality with a focus on QoS provisioning, moreover it will approach a study in scope of the whole network, particularly, focusing on a design of the control plane for OMPLS (Optical MPLS) networks, as well as in evaluation of the routing algorithms. At last, we will begin a new topic that consists of an adaptation the technique of optical packets commutation for designing the architectures for high performance computers.
The RINGING subproject concerns the design and building of a reconfigurable optical node with an advanced design, and its further integration into a real network to develop a field trial. The main objective of this subproject is the integration of reconfigurable optical nodes in the GMPL/ASON network, which has been obtained as a result of the CARISMA project. Thanks to the participation in TRIPODE, CARISMA, and FIRM (Field trial with Integrated ROADMs and GMPLS compliance, the CELTIC-EUREKA-2004 project, www.celtic-iniciative.org) projects, the know-how necessary for the implementation of the reconfigurable optical nodes is ready. The subproject is divided in two main blocks. The first one will be dedicated to building reconfigurable optical nodes, while in the other, the aspects of the integration of these nodes in an optical network which was constructed during the CARISMA project, will be treated. Introduction of the traffic engineering (TE) techniques into GMPLS/ASON networks, which will result in a network able to provide optical virtual private networks (OVPN) as well as suitable for working in a GRID environment of great importance in the next future, should be highlighted among the most important general objectives of this subproject. For the development of these last objectives also the participation in PROMISE (Provisioning and monitoring of optical services, CELTIC-EUREKA-2004 project) project will be useful.

Several standardization bodies (UIT-T, 3GPP and IETF) are working on the definition of Next
Generation Network Architectures based on All-IP and Always Best Served concepts. Key
level of Architectures proposed by those bodies are organised around the service layer, which
offers to applications support for integration, deployment and operation of the end user services.
This service layer is based on the underlying IP transport layer which offers support for QoS,
security, etc, supporting the next generation applications.
This project aims to define one Architecture for next Generation services provision, which enables the creation of a service centre. The Architecture will enclose key elements of architectures of main standardisation bodies, and will focus on the service layer over heterogeneous access network, including wireless, cellular and fixed networks. Associated to the proposed Architecture, a Service Centre will be defined and setting up, for delivering end-user services.
End-to-end service provision over heterogeneous IP networks, including facilities for bandwidth on demand, guarantied bandwidth, QoS support, multi-diffusion, interworking of IPv4 and IPv6 networks among others is not a well solved problem, mainly because the problems due to the different domain involved in the service provision. Most of the existing solutions for monitoring and traffic measurement are designed for a single domain, and just a few refers to inter-main scenarios (hierarchic scenarios). This research project aims to integrate three research areas (monitoring and traffic measurement, traffic engineering and routing) in the context of inter- domain service provision.
The development of electronic technology and radio software, among others, will determine that in the near future the operation of radio networks will be characterised by the availability of multi- technology terminals such as GSM/EDGE and WCDMA. In this scenario, the coordinated management of radio resources, minimising their usage and guarantying QoS requirements for the end users, will become a key point. The objective of the project id the design of new policies for controlling admission of new session en multi-access systems and multi-service scenarios, capable of adapting to changing traffic conditions and that allows exploiting information regarding future hand-hovers of new sessions. Those policies have to guaranty at least the next QoS objectives: the probability of blocking new sessions, the probability of shutting down existing sessions and the probably of outage.

The proposed Network of Excellence (NoE) aims at integrating and focusing the rich know-how available in Europe on optical communication and networks, both in universities and in research centres of major telecom manufacturers and operators. The set of available expertises ranges from optical technologies, to networking devices, to network architectures and protocols, to the new services fostered by photonic technologies. The NoE will contribute to the Strategic Objective Broadband for All, with a particular focus (quoting from the EC IST 2003-2004 Workprogramme at page 15) on low cost access equipment, on new concepts for network management, control and protocols, and on increasing bandwidth capacity in the access network as well in the underlying optical core/metro network (including in particular optical burst and packet switching). The main technical focus of the NoE is to show which are the potential advantages of optical technologies in telecommunication networks with respect to electronic technologies. A strong integration among the participants to the NoE will favour a consensus on the engineering choices towards the deployment of costeffective optical technologies in networking that will support the future Internet, hopefully providing inputs to the standardization bodies and guidelines to the operators, as well as competitive advantages to European telecom equipment manufacturers. Integration will be pursued primarily by establishing long-term collaborations among partners in terms of research, of infrastructures sharing, and of education and training. The main instruments to achieve these long- lasting collaborations are the regular exchange of researchers between partners, and the development of joint teaching programs and events. Dissemination will be pursued by means of coordinated publication activities, offerings of training programs, organization of technical events, and interactions with other consortia in the same technical area. Research activities will mainly be carried out in research programs external to the NoE, both at the national and at the European levels. Well focused technical research programs will be activated internally to the NoE.
e-Photon/ONe involves 37 partners, coming from 12 member states (Austria, Belgium, Denmark, France, Germany, Greece, Italy, Netherlands, Spain, Sweden, Portugal, United Kingdom), 3 candidate countries (Hungary, Poland, Turkey) and 2 third countries (Croatia, applicant country and target INCO West Balkan country, and Norway, associated country). The consortium is composed by 29 universities and other higher education institutes, 4 telecom operators, 1 manufacturer, 3 non-profit research centres.

SMARTxAC is a project carried out under a collaboration agreement between the Advanced Broadband Communications Center (CCABA) of the Technical University of Catalonia (UPC) and the Supercomputing Center of Catalonia (CESCA).
SMARTxAC aims to develop and deploy a passive measurement infrastructure and a real-time analysis system for high-speed links. Currently, SMARTxAC is being used for capturing and analyzing the traffic of the Anella CientÃfica (Scientific Ring). The Anella CientÃfica is the name of the Catalan R&D Network, which is managed by CESCA and connects about 50 Universities and Research Centers in Catalonia.
The tapped link is built from a pair of GigE links (one for each traffic direction) that connect the Anella CientÃfica to RedIRIS (Spanish R&D network) and to the global Internet. Current traffic volume on this link is about 600 Mbps and it is increasing day after day, so that data collection is facilitated by an Endace DAG 4.3GE measurement card. Full-traffic analysis at full-line rate is performed in real-time using the SMARTxAC analysis software developed at the Advanced Broadband Communications Center (CCABA) of the UPC.
A three hours GPS-synchronized and anonymized IP header trace was captured for the NLANR/PMA project in February 2004 using the capture point and collection platform in the Anella CientÃfica. This data set was published and can be downloaded at CESCA-I section of NLANR/PMA website.

The goal of the SAM project is the design, experimentation and evaluation of architectures of an Internet network with mobility support. The project will create a network testbed by interconnecting wireless access demonstrators in the participating institutions through Red Iris 2. The following access technologies will be considered as a minimum: Wireless LANs, GPRS or UMTS. The testbed will be used to study, experiment and validate solutions to the following unresolved problems: - Mobile access over second and third generation wireless links. - Macromobility protocols. - Micromobility protocols. - Provision of QoS in a mobile context. - IPv6 usage in a mobile context. - Multicast in a mobile context. - User mobility: globalization of session management. - Provision of Security. The project will implement, compare and validate the proposed solutions over this network testbed and will propose new solutions for the unresolved problems. The validation in real working conditions will be performed with real time synchronous collaboration services, such as the tele-meeting and teletraining services of the Isabel application. Those services are considered the most adequate for this purpose; due to the demanding operating requirements and to the benefits that mobility can offer to them. The SAM project is a continuation of the SABADOS project of the Spanish National Research Program on Information and Communication Technologies and has the objective of exploring the evolution paths for including mobility in the Spanish academic research network. SAM will take as starting point the results of SABADOS, including the already developed service platform, as well as the solutions proposed and validated for adding next generation Internet features to the present Internet architecture. The platform will be enhanced with mobility, mew proposals will be developed and special emphasis will be put on submitting results to standards organisation, in particular the IETF

LONG aims to foresee and solve problems related to the design, configuration and deployment of Next Generation Telecommunication networks specially when new services and applications are carried out across them.
The new version of the IP protocol, IPv6, will become an integral part of these Next Generation networks. In addition to this, the proliferation of new high bandwidth and asymmetric access technologies, like ADSL and CATV, will also shape the network design of these Next Generation Networks. On the other side, applications must be aware of the advanced services provided by the networks and protocols, and must take into account the impact of the underlying network. LONG aims at gaining an in-depth knowledge in the design and deployment of IPv4/IPv6 transition scenarios, as well as in the operational inter-working when heterogeneous access (ADSL, CATV, ISDN) and transport (IP/ATM, IP/SDH, IP/WDM) technologies are in place. The integration of IPv6 with advanced network services will be validated in LONG.
On the other hand, LONG focuses on extending the framework of applications, so that they benefit from the services provided by these Next Generation networks. In order to achieve these goals, LONG faces the following objectives:

Main objective is to propose a Packet-over-WDM network solution, including traffic properties and management, based on optical packets and asynchronous transmission over metro and backbone distances. The project will capitalise on both optics and electronics to find out the optimum combination to reach multi-Tb/s capacity. To cope with the on-going convergence in the transport of voice, data and multimedia applications, the project will also define several classes of service, adapted to optical layer specifics. On the metro side, the project will consider a buffer-less network using a medium access control protocol. The backbone will be based on 10 Tb/s multi-layer (wavelength and packet) opto-electronic medium access control protocol with opto-electronic packet routers, incorporating core and edge functions. Finally, the project will demonstrate highly integrated optical and electronic devices, included in a sub-equipped experimental platform. Work description: A first task will be to tackle the network issues: - Define network requirements and functional specifications of the network elements; - identify a migration path from short-term approaches; - Carry out traffic studies to analyse IP traffic behaviour when transported over WDM, and propose optimised buffering schemes, access control protocols and routing algorithms taking into account a multi-QoS environment; - Investigate network management issues, such as interoperability between packet and WDM levels. A second task will be to investigate and implement the required network elements: - A network testbed will be implemented with its associated access control protocol to show a buffer-less multi-QoS optical packet metro network of capacity beyond 1Tb/s (2.5Gb/s line-rate); - A 10-Tb/s opto-electronic optical packet router (2.5/10Gb/s line-rate) incorporating gateway functions between metro and backbone will be implemented using a two-layer (wavelength and packet) approach; A third task will be to provide the required advanced components: - Fast and highly integrated optical space and wavelength switching modules, based on semiconductor optical amplifiers (up to 32 gates per module), and incorporating adapted high-speed electronic drivers; - electronics for clock recovery, buffering, and switching will be developed, based on SiGe and III/V technologies. Milestones: - Functional definition and migration path of optical-packet-over-WDM scenario - Analysis of traffic models and logical network performance; - Info-model of packet/WDM management; - Test-bed including metro network, optical packet router and interfaces to IP - New architectures and routing techniques, 40Gb/s studies; - Optical switch modules (32 gates); - Electronics for signal processing.

LION aims at giving answers to Network Operators (N.O.) about interoperability of client transport networks (e.g. ATM, SDH, IP-based) over an optical server one recommended as Optical Transport Network (OTN). In particular, the major target is to design and test over a testbed a multi-layer resilient network in a multi-domain environment. First the N.O. requirements will be defined for envisaged multi-layer network scenarios. Cost-effective integrated resilience strategies will be investigated supported by planning evaluations. The ITU-T functional modelling will be adopted to define first the OA&M and management requirements and then specifications for interfaces between network clients and OTN and between OTN domains. An "umbrella" management architecture that enables integration of TMN, WBEM, and SNMP will be designed to allow N.O. to manage the network as a whole. The above requirements and specifications will be translated into systems and sub-systems implementation to test in a testbed.
The goal is to design and test a resilient and managed transport network realised by an OTN carrying different clients (e.g. SDH, ATM, IP-based) with interworking and interconnection between layer transport networks and domains. The identified requirements will be validated in a testbed where IP-routers and SDH equipment will be integrated over an OTN infrastructure. The following objectives will be met: define the interworking and interconnection requirements between client-server layer networks and domains; define the functional requirements of an IP-based transport network; enhance the functional architecture of an OTN to account for new emerging features (e.g. digital optical container); implement, integrate and test Network Node Interfaces (NNI) between transparent domains and Client Node Interfaces (CNI), both based on digital optical container; implement, integrate and test an "umbrella" management system over a testbed; to develop and test strategies for integrated resilience controlled by an overall OA&M and a management system adopting QoS demanding applications; make techno-economic evaluations of an IP-based network over an OTN.
The following milestones/results are foreseen: integrated multi-layer network requirements and scenarios; functional description of an integrated OTN carrying multi-clients; functional requirements and implementation of CNI and NNI based on digital optical container; design of an "umbrella" management architecture implemented with CORBA and WBEM; OA&M concepts in an integrated multi-layer network; resilience interworking strategies in multi-layer networks; multi-layer resilient network planning and evaluation; testbed validation experiments.

The primary objective of the Action is to devise possible architectures for the next generation of high capacity optical transport and also access networks. The target architecture should
o provide virtually unlimited end-to-end bandwidth regardless of distance enabling instant movement of huge amounts of data for applications,
o enable efficient and simple multicasting and broadcasting of broadband signals,
o be flexible and agile in order to accommodate abrupt and unpredictable traffic surges and to react instantaneously when failures occur, allowing seamless and errorless transmission of large data blocks,
o be transparent to all sorts of digital signals and protocols so that it would enable to accommodate a number of network types and services simultaneously or in succession deployed over time,
o trade bandwidth for simplicity to alleviate the complexity problem in the communication networks resulting mainly from the ever increasing amount of software residing in the networks that raises costs and lowers reliability of the networks.
