Research on P2P Network Topology Based on MBTN

为了进一步提高P2P网络的服务质量,构建性能更为优良的P2P网络,提出了一种新的基于平衡多叉树P2P网络(MBTN)拓扑构建方案,对相关的调度算法进行了研究,并详细阐述了在该拓扑网络上节点加入和退出算法.最后,从节点平均恢复时间、平均延迟时间两方面对MBTN拓扑结构组播网络上的P2P业务进行仿真试验.实验表明,基于MBTN仿真出的拓扑网络可以有效减少节点恢复时间和延迟时间,较好地降低了控制成本.

In order to construct more efficient P2P network topology and improve the quality of service of P2P network,a novel topological architecture and scheduling algorithm based on multi-balance tree networks in the application level are provided,which node joining algorithm,node exit algorithm,and so on.Results of simulation experiment show that the method can effectively reduce the average recovery time and delay time and better reduce the control cost.
