چکیده

In order to provide QoS in group communications for real time applications such as video conferencing, reliable multicasting is used. Miscellaneous efforts have been undertaken to provide reliability on top of IP multicast. In this paper, we present a new fair share policy (FSP) that utilizes Differentiated Services to solve the problems of QoS and congestion control when reliable FEC multicast is adopted. Simulation programs are used to evaluate the Fair Share Policy. The results should provide insights into the comparisons between IP multicast in MPLS networks using FSP and plain IP multicasting using the same policy when DiffServ are adopted and when reliable FEC/ARQ multicast is considered. Key-Words: Multicast, IP, MPLS, DiffServ, FEC/ARQ.

Error Control Techniques for Efficient Multicast Streaming in UMTS Networks

In this paper we introduce techniques for efficient multicast video streaming in UMTS networks. Multicast streaming is based on the fact that the same video content is conveyed to multiple users in the same cell. Efficient multicast data delivery in UMTS is still an open issue. In particular, suitable solutions have to be found to cope with wireless channel errors, while maintaining both an acc...
