摘要
为了优化对等网络(P2P Network)中节点间的数据传输性能,加强对等网络的系统稳定性,提出了一个基于对等网络的新型节点管理机制。按照P2P网络中节点的网络特性对节点进行分组,分组内节点按照传输性能进行分层。系统基于这种双层结构,利用根节点和组内主节点进行集中式控制和管理分组的创建,组成员的加入、离开,数据传播和失效等行为,能够较好地支持实时的多应用。通过与传统随机构建的网络结构进行仿真对比,证明构建这种结构化层状网络,可有效地减少节点间的网络距离,提高应用层多播的传输性能。
In order to improve the performance of transmission and stability of system, a self-organization mechanism for nodes management in P2P network was proposed. Nodes are grouped according to its network attributes in the overlay network. Nodes in the same group are layered according to the performance of transmission. Its group management and member management were in centralized way. It is proved to be effective in shortening the net distance and improving the performance of the application layer multicast through this layered network.
