Abstract :
The phenomenal growths of group communications and QoS-aware applications over the Internet have accelerated the development of two key technologies, namely, multicasting and Differentiated Services (DiffServ). Although both are complementary technologies, the integration of the two technologies is a non-trivial task due to architectural conflicts between multicasting and DiffServ. We propose a protocol for member join/leave in a DiffServ network that is scalable in terms of group size, network size, and number of groups. We detail our join/leave protocol for both intra-domain and inter-domain routing as well as the various different types of multicast trees (single source tree, shortest path tree, shared tree, many-to-many tree). Finally, we present simulation studies regarding the performance of our join/leave protocol
