The paper analyzes two solutions (IPv4 and IPv6) for interworking of network portions implementing different QoS technologies and belonging to diverse Autonomous Systems (ASes). While the implementation of QoS is a AS’s concern, three topical problems should be solved at the interworking points (called Relay Points, RPs, in the paper): 1) the definition of the RP convergence technology, 2) the signalling between the RPs, 3) the bandwidth pipes dimensioning for flows traversing the heterogeneous network. The paper investigates these points and proposes a description of the Service Level Agreements available in the heterogeneous network as function of the RP protocol architecture.
The RP stack proposed needs to interact with ASes QoS-solutions. It means that the RP QoS must be “mapped” on alternative technologies (DiffServ, IntServ, ATM and so on), implemented locally. This leads to the analysis of the traffic aggregation effect on the performance, e.g., if traffic requiring different performance is joined in one flow for technological reasons. The results reported, obtained through simulations, investigate this topic and allow providing operative solutions applicable in the field.
Mario Marchese - University of Genoa
He got his "Laurea" degree cum laude at the University of Genoa, Italy in 1992 and obtained his Ph.D. degree in "Telecommunications" at the University of Genoa in 1996. From 1999 to 2004, he worked with the Italian Consortium of Telecommunications (CNIT), by the University of Genoa Research Unit, where he was Head of Research. From February 2005 he has been Associate Professor at the University of Genoa, Department of Communication, Computer and Systems Science (DIST). He is the founder and still the technical responsible of CNIT/DIST Satellite Communication and Networking Laboratory (SCNL) by the University of Genoa. He is also Vice-Chair of the IEEE Satellite and Space Communications Technical Committee and Senior Member of the IEEE. He is author and co-author of more than 80 scientific works, including international magazines, international conferences and books.
