摘　　要：针对环形P2P网络中节点的维护消息数量随邻居节点数量线性增加和传统P2P网络令牌机制无法控制令牌数量的问题,提出了利用控速令牌维护环形P2P网络的方法。令牌以消息的形式在环形P2P网络中传递,令牌将途中经过的节点信息加入其中,其它节点利用令牌中的信息维持网络结构,并使用控速参数减少网络中的令牌数量。仿真结果表明,控速参数能够有效地降低P2P网络的令牌数量;随着网络规模的增大,节点平均维护开销维持不变。In order to solve the problem of maintenance messages increased linearly with the number of neighbors in the ring-like P2P network and traditional P2P network token mechanism could not control the token number, we proposed method of control speed token to maintain the ring-like P2P network. Token transmit in ring-link P2P network in the form of message, and node information could record in token in order to keep the structure of network for other nodes. P2P network used control speed parameter to reduce the number of tokens. Simulation shows that control speed parameter could effectively reduce the number of token in P2P network With the increasing scale of the network, the average maintenance costs of node remain unchanged.
