摘要
结构化的P2P网络路由效率的低效性和P2P网络中节点自私行为导致可用资源的变数是影响结构化P2P网络可用性的两大主要问题。文中提出了一种典型的结构化P2P网络资源共享平台实现框架的模块划分图,并指出了可用性增强问题在框架图中的位置和接口。论述了这两类问题的当前研究进展,从适应网络自组织管理模式以及适应规模可缩放性这两个角度分析并评述了已有的增强结构化P2P网络可用性的诸多解决方案。最后针对当前结构化P2P网络可用性增强问题研究中的不足,给出了一些研究思路,这些将对推动结构化P2P网络技术的实用化进程提供有益的参考。
Due to self-organizing management model having a huge impact on the availability of the structure peer-to-peer networks,to enhance the availability has been becoming more important.From the perspective of structured P2P networks architecture,a novel layered module framework for resource sharing platform is proposed.And based on the layered module framework,two most key issues impacting structured P2P networks availability are discussed in detail,one is low-efficiency of structured P2P network routing algorithm,and the other is selfish node＇s behavior leading to the available resources variable and unstable.Further more,the current progresses of these two issues are summarized.Finally,some novel research ideas to enhance the availability of structured P2P networks are proposed.These work should be applied to the availability enhancement of structured P2P networks and their applications.
