Abstract:

ACP is a buffer management protocol applied to shared environment. However, when multicast group number or group member changes, ACP can hardly adjust its allocation quota in time and this will lead to the decrease of cache utilization ratio. To address these drawbacks, a new buffer management scheme called Adaptive and Active Reliable Multicast Protocol (AARM) was proposed, for largescale multicast network. Simulation results show, AARM outperforms ACP in reducing recovery latency and bandwidth consumption, and raising network throughput.
