随着信息技术的发展,计算机技术和通信技术在发展过程中,整个互联网内容储存的方式趋势在不断的转变,从传统的基于客服机/服务器的内容交换模式变化为今天的基于对等模式(简称P2P)的内容交换模式。大部分的结构化对等网络都定位于采用纯分布式的消息传递机制和根据关键字机型查找的服务模式,在各个领域已经得到广泛的应用。但是结构化对等网络在路由机制和路由计算中还面临着许多问题,先阐述对等网络和非对等网络的区别,再从对等网络的P2P路由计算中总结出一种结构化P2P协议中的缓存计算模型。最后提出研究对等网络路由机制技术的意义和作用,指出在实际研究中的一些主要问题,给出一些相对性的建议。
With the development of information technology, the development of computer technology and communication technology has changed the way of storing the entire Internet content. From the traditional content-based service-server / server-based exchange model to today’s peer-to-peer model Referred to as P2P) content exchange mode. Most of the structured peer-to-peer networks are located in the use of purely distributed messaging mechanisms and search services based on keyword models, which have been widely used in various fields. However, structured peer-to-peer networks still face many problems in routing mechanism and routing computation. First, the difference between peer-to-peer networks and non-peer-to-peer networks is elaborated. Then, a structured P2P protocol In the cache computing model. At last, it puts forward the significance and function of studying the peer-to-peer routing mechanism technology, points out some major problems in practical research, and gives some relative suggestions.
