基于复杂网络理论的P2P覆盖网拓扑结构研究

Research of P2P overlay topology structure based on complex network theory

覆盖网拓扑结构是P2P领域的一个关键问题。随着计算机网络的快速发展,网络结构日益复杂,使得传统的随机网络模型已很难对其拓扑特性做出客观的描述。复杂网络理论作为一门新兴的学科为P2P网络的拓扑结构研究提供一个新的视野和思路。介绍复杂网络理论和传统的拓扑结构,综述当前基于复杂网络理论的计算机网络拓扑的研究状况,最后对复杂网络理论在未来拓扑结构研究中的可能应用方向作了总结和展望。

Overlay topology structure is a key problem in P2P application.With the rapid development of computer networks, the networks structure is more and more complicated.As a result,the traditional random network model is difficult to characterize the overlay topology.As a newly burgeoning subject,complex network theory provides a new view and thinking to the study of P2P overlay topology strure.The complex network theory and traditional topology struture are introdueed,the researche status on computer network topology based on complex network theory is summarized.Finally,a brief conclusion is presented, as well as future research on topology structure based on complex network theory.
