摘要
针对DHT类型的P2P协议在网络演进的过程中会产生超级节点,进而导致度分布严重失衡,网络传输的平均时延增大的问题,该文在Chord协议的基础上提出了一种新的具有递归结构的P2P协议:R-Chord,并进行了仿真分析.结果说明,该协议能够有效抑制超级节点的产生,使节点的度分布趋于均匀,使网络的负载在节点间的分布更均衡.
Against the procedure of DHT P2P protocol in internet produced peer connections and induced distribution severely unbalance, enhance the average delay of net transmission. Based on Chord, we suggest a new P2P protocol which has recursive structure, call R-Chord, and preformed emulational analysis. The results show that this agreement could restrain peer connection and make connection distribution equably, net workload distribute evenly between connections.
