摘要
针对当前P2P网络模型存在逻辑拓扑与物理拓扑失配和没有充分考虑节点异构性的缺点,利用IPv6特有的层次化地理布局,实现逻辑拓扑与物理拓扑的有效结合,应用簇减少节点频繁加入和退出所带来的网络抖动问题,充分考虑节点之间的性能差异,让性能好的节点承担更多的任务,利用节点成功的资源访问记录进一步提高路由效率。通过模拟实验和对相关数据的分析,证明该项研究能使路由延迟减少,网络更稳定,更易于管理和维护。
In view of the mismatch between P2P overlay network topology and physical network topology, and neglecting of the heterogeneity of peers, this paper applies IPv6 hierarchical structure to make overlay network being congruent to physical network, introduces cluster to decrease churn of the network due to frequent joining and leaving of the peers takes into account the heterogeneity of peers chooses peers with great capability to take more responsibility in routing; and adopts successful resource lookup history to improve routing efficiency. Simulation experiments and analysis of involved data show that the research can make routing delay decrease, network more stable and easy to manage and maintain.
