Chapter 2 presents the architectures of content switching , classifies and describes main current routing mechanisms and dispatching request algorithms to split the load among the server nodes , and analyses their performance character qualitatively 第二章介绍了内容交换的结构,分类阐述了当前用于内容交换的各种分发算法和路由机制,并对这些算法和机制做了简单的分析比较。
Cdn can be divided into three independent building blocks in addition to the network infrastructure : content routing , content delivery , and performance measurement . there are two different aspects to content routing . the first is the global routing ; the second addresses the local routing ( or content switching ) , which is the main topic of this paper 内容分送网络主要涉及的关键技术包括内容路由、内容分发和网络性能的测量,其中内容路由包括全局路由和局部路由,局部路由又称内容交换,是本文的研究对象。
