摘要
当P2P网络中的接点发生错误或者离开信息丢失等情况时容易造成节点的失效以及拓扑结构异常,严重影响P2P网络的效率和健壮度。如何快速重构产生异常的P2P网络结构是本文的研究重点。本文通过将改进的心跳协议作为主动探测措施与作为被动探测措施的信息捎带协议结合,利用根据信息重要度建立的概率模型建立了一种用于解决P2P网络快速重建的机制。该机制使P2P网络自恢复所占用的带宽更小,达到稳定状态的速度更快。
The article present a solution which has two mechanism, active and passive, to make the P2P self-recovery from node failure and message lost. In the active mechanism, each node periodically send detect message to the front k nodes in the node-queue. In the passive mechanism, the state of nodes was send to destination node in company with ordinary data. According this attendant state of the source node the nodes along the routing path can determine whether the source node was alive in a certain probability. ...
