Reliable Multicast Using Adaptive Caching

摘要

This paper presents the system, protocol and performance of RMAC (Reliable Multicast using Adaptive Caching). RMAC provides router-assisted reliable multicast transport. We believe that computations within the network are required to make reliable multicast effective. RMAC improves retransmission efficiency by caching and retransmission at routers within the network, and reduces router cache size by caching data packets distributedly over RMAC routers and adaptively to conditions of network. Simulation results show RMAC decreases recovery latency, and improves cache utilization as well as scalability compared with the conventional schemes for reliable multicast.
