Abstract: Aggregated multicast is a new focused solution to that problem of multicast state scalability, but current aggregated multicast algorithms and protocols lack load balance mechanism of network flows. An aggregated multicast protocol based on load balance, AMPLB is proposed. Simulation results demonstrate that this protocol keeps aggregation performance when balances network flow distribution and decreases the risk of congestion so as to improve the performance of large-scale multicast network.

Key words: aggregated multicast, load balance, congested rate, aggregation degree

摘要： 聚合组播技术是近年来针对组播状态可扩展性问题提出的热点方案，但现有的聚合组播算法和协议缺乏网络流量的负载均衡机制，使网络整体利用效率下降，并容易因聚合产生拥塞。为此，提出一种基于负载均衡的聚合组播协议AMPLB，仿真结果表明其在保证聚合性能的同时使网络流量分布更加均衡，降低出现拥塞的风险，可较好地改善大规模组播网络的性能。
