The research group started in 1992 and belongs to the Computer Architecture Department of the Tecnical University of Catalunya (UPC BarcelonaTECH). The University has been granted as Campus of International Excellence (Barcelona Knowledge Campus) and the Computer Architecture Department holds a PhD Program awarded by a Quality Honourable Mention by the Spanish Ministry since 2003. The research group is recognised both as a research group of the UPC and as a consolidated research group of the Catalan Goverment Generalitat de Catalunya (2005SGR-00481 for the period 2005-2008, 2009SGR-1140 for the period 2009-2013, and 2014SGR-1427 for the period 2014-2016).

 

Most of the topics covered by this research group are strongly related with broadband networks and broadband services and applications: switching, protocol development and performance, traffic modeling, network resource management policies and bandwidth allocation, traffic and congestion control, routing strategies,  internetworking, network management, IP and optical networks convergence, quality of service management and transport protocols.

 

Key research topics are:
