摘要

"热点"问题是导致结构化P2P网络负载失衡进而影响检索效率的重要因素.在给出节点下载量与被下载量以及"热点"信息与"冷点"信息管理机制的基础上

利用"热点"节点与"冷点"节点的互补特点

提出了推拉结合的结构化P2P网络"热点"负载动态迁移策略.由于是由"热点"节点和"冷点"节点的邻居节点来触发负载迁移过程

消除了因P2P节点的自私性而带来的对负载迁移不协作问题.模拟实验结果表明

所提出的策略能够有效地解决结构化P2P网络的"热点"问题且在工程上是可行的.

Abstract

"Hotspot" problem is an important factor of causing the load imbalance and then affecting the retrieval efficiency in structured P2P networks.In this paper

the mechanisms for managing the amount of node's download and upload as well as the information of the "hotspot" nodes and the "cold spot" nodes are described and then the push and pull combined "hotspot" load migration strategy in structured P2P network is proposed by utilizing the complementary nature of "hotspot" nodes and "cold spot" nodes.Since the load migration processes are triggered by their neighbor nodes of "hotspot" or "cold spot"

the non-cooperative problem brought by the nodes due to their selfishness for the load migration can be eliminated.The experimental results show that the proposed strategy is effective in handling "hotspot" problem in structured P2P networks and easy to put into practice.
