摘　　要：监控是P2P系统的一个重要组成部分。本文设计了一个用于实时流媒体服务的监控系统,它采用邻近原则构建一个控制层次树对监控数据进行分散采集、逐层汇总,具有扩展性能好、网络开销小等特点,并实现了对Anysee++系统的监控。Monitoring is an important problem needed to be solved in P2P systems. The design, implementation and performance analysis of a monitoring system for P2P real media streaming services is presented in this paper. A locality-aware hierarchical tree is constructed to implement monitoring information＇s collecting and merging, which has high scalability and causes low network overheads. A practical monitoring system for Anysee＋＋, which is a P2P real media streaming system, is implemented, and the performance analysis demonstrates its effectiveness in achieving high scalability with low network overheads.
