Design and Performance Evaluation of Broadband Integrated Communication Systems

Some of the topics covered by this research line are: Broadband Integrated Communication Networks: protocols, reference connection, signalling, operation and maintenance functions. Asynchronous Transfer Mode, Source traffic modelization for the new services (CBR, VBR). ATM switching: basic switching elements, multistage interconnection networks, analytic models. Performance of multiplexing and switching elements. Traffic Control and Network Resource Management for ATM BISDN: policing functions, connection admission control, priorities, cell spacing, cell delay variation, congestion control, Broadband access facilities: topologies, medium access protocols. ATM local area networks. Internetworking units: high speed networking, MAN, LAN, WAN, ATM internetworking.
