Dynamic replier active reliable multicast (drarm

Desirable features of reliable multicast include low end-to-end delays, high throughput and scalability, and meeting these objectives is not an easy task. We propose a receiver-based (replier) local recovery multicast protocol with dy-namic repliers elected on a per-packet basis. Designed to provide an efficient reliable multicast service without any cache facilities in the multicast tree, our approach, noted DyRAM, uses low-overhead active services in routers. Af-ter presenting the protocol and some designed and imple-mentation issues the paper compares DyRAM to ARM, the nearest active reliable multicast protocol in term of func-tionalities proposed in the active multicast community. Sim-ulation results show that DyRAM performs much better than an ARM-like protocol which needs a significant amount of cache to exhibit performances. Additionally, in case some cache is available for DyRAM and ARM, the study shows that DyRAM always performs better than ARM. 1
