摘　　要：P2P重叠网以其系统高效性和有效性被广泛应用于分布式网络管理系统中。但是,传统P2P重叠网络的设计往往只关注其P2P特性,忽略了重叠网自身的管理问题;另外,P2P网络强调的是参与者的平等性,忽略了各参与节点自身性能的差异,从而极大影响了系统的整体性能。本文提出一种基于模糊逻辑的资源感知P2P重叠网,系统中的每个参与节点负责管理一部分网元设备,并充分考虑各节点所管理资源的可用性及其所处环境的时变特性,同时利用基于策略的网络管理方式,构建了一种动态和自主的P2P重叠网网络管理系统。仿真结果证明了该方案在网络管理中的可行性和有效性。P2P overlay networks are widely used for distributed network management owing to the effective and efficient way they provide that are not otherwise available.However,most of the designs about P2P overlay construction mainly focus on introducing the P2P approaches,lacking a mechanism for overlay self-management.Furthermore,due to the faith of emphasizing equality among participators,peers are tend to be treated equally in the P2P overlay network,which greatly affects the system＇s performance.This paper presents a novel approach to address the issue of automating the P2P overlay management with the consideration of the resource availability of each peer.In the system,each participating peer is responsible for the management of certain network equipments.We utilize a policy-based management paradigm for overlay and network reconfiguration.The new approach provides a dynamic and autonomic way to manage the P2P overlay network.The simulation results verify the feasibility and effectiveness of our schema.
