Scalability of Two Reliable Multicast Protocols
Overview Growing demand for multicast communication in large network settings has focused attention on the scalability of reliable multicast protocols. This paper uses both simulation tools and experiments to compare two scalable protocols, focusing on an aspect not often studied: it emphasize stability of latency distributions as these protocols scale, although also considering overhead and link utilization. These properties are considered in a variety of network topologies and with several levels of packet loss. The findings confirm that SRM scales poorly under some conditions: to obtain reliability, the protocol incurs overhead linear in group size and throughput fluctuates erratically. The paper also shows that SRM latencies can be very large and that latency distributions are unstable as a function of group size and network topology.
