Abstract:

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 c  collecting and merging, which has high scalability and causes low network overheads. A practical monitoring system for Anysee＋＋, which is a P2P real m  media streaming system, is implemented, and the performance analysis demonstrates its effectiveness in achieving high scalability with low network overheads.

Key words: （P2P, media strearning, monitor, locality-aware, scalability）
