| 摘 要： | 提出了BitwiseTree,利用二元位运算确定复本放置,而不需要像其他基于日志的复制技术需要考虑客户访问日志;同时BitwiseTree提供的容错机制保证失效节点中的文件可以在其他复制节点中找到。仿真实验表明,BitwiseTree只需要使用较少的复本就能达到有效地缓解节点过载的目的,因此该模型非常适合无法获得客户访问日志的机密P2P系统或者对系统性能要求比较高的P2P系统。

| Abstract: | Replicating techniques are frequently used in a high performance distributed system to reduce the load of the overload nodes.Traditional file replication algorithms rely on the analysis of client-access logs to determine the location of the replicated nodes.This paper presents a fault-tolerant BitwiseTree model for peer to peer system.It constructs a replication tree for each node,and then uses bitwise operations to determine the location of the replicated node without any client-access history.In addition,... |
