摘要:
提出一种基于全局复合评价算法的Super Peer选择机制,该机制以主客观相结合的科学依据从多方面自动选择P2P网络中稳定可靠、长期在线且积极提供服务的大量高性能Peer担当Super Peer职责,从而可以极大地扩充Super Peer的数量,使得全分布式结构化拓扑和半分布式拓扑结构可以在同一个P2P网络中有效地互补并存.全局复合评价算法综合采用在线活跃情况、任务完成能力和平均通信速率这3个指标来作为Super Peer的选择标准.构建了P2P仿真实验系统环境,验证所提出的算法和相应机制的可行性和实用价值.
Abstract:
A new selection mechanism of Super Peer based on the global complex evaluation algorithm is proposed in this paper to automatically choose stable and reliable peers, which are online with long time and provide services actively, from P2P(peer-to-peer)network to be Super Peer. In this way, the amount of Super Peer is expanded greatly so that decentralized structured topology and partially decentralized topology are able to coexist in one P2P network and effectively complement each other. The global complex evaluation algorithm comprehensively adopts three indicators as the Super Peer selection criteria, i.e., online activity, the ability to complete tasks and the average rate of communication. The P2P system simulation environment is also constructed to verify the proposed algorithm and the corresponding mechanisms for their feasibility and practical value.
