对等网络点播系统中一种分布式索引结构
Distributed indexing structure in peer-to-peer video-on-demand systems
摘要
Abstract
To meet the requirement of fast resource location for users' fluent playback or their interactive operations in the P2P (peer-to-peer) VoD (video-on-demand) system, a distributed resource indexing structure was proposed to promote the efficiency of the location of target nodes. The indexing structure was constructed and maintained by a number of relative stable peers that were adaptively selected from the system. And its operation was supported via the cooperation of those relative stable peers, so the system dynamic could be overcome in a large extent. The proposed light weighted resource location strategy could adaptively turn according to user scale, which made it present a good scalability. Simulation results show that the indexing structure can help users for fast resource location within 3 or 4 hops under low overhead, which can reduce the response latency of users' interactive operations.关键词
