| 摘 要： | 目前非结构P2P系统所采用的两层聚类结构HCPON存在的问题是超级节点仅采用单一的备份节点作为冗余备份,使得系统健壮性的提高很有限。由此提出基于三层聚类结构的高效P2P系统（PTLCA）,根据节点的拓扑优先级等对节点进行分层处理和聚类,同HCPON相比,PTLCA在性能上有显著的提高,能够满足大规模流媒体服务的需求。

| Abstract: | At present non-structural P2P system using two-layers cluster structure(HCPON)has some shortcomings:super peer uses solely one peer for redundancy backup,which limited the improvement of the system’s robustness.This paper proposes an efficient P2P system named PTLCA which is based on three-layered cluster architecture.It partitions peers into different layers and clusters according to the topology priority.By comparison with HCPON,PTLCA is more effective on system performance and it can satisfy the need of large scale media service. |
