| 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P2...

| 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 migrati... |
