摘　　要：动态网络允许应用程序将用户特制的程序注入网络节点,从而使得配置新的网络协议更加容易,协议的升级也更快。该文主要讨论引入动态协议对分布的端-端应用性能的影响。文章首先介绍一些提供novell网络服务的动态协议,并讨论其对端-端应用性能的潜在影响。接下来,具体介绍一个利用网络主干内的缓存处理来降低服务器和主干路由负载的动态协议,并定量分析其性能。An active network allows applications to inject customized programs into network nodes.This enables faster protocol innovation by making it easier to deploy new network protocols,even over the wide area.This paper argues that the ability to introduce active protocols offers important opportunities for end -to -end performance improvements of distributed applications.At first,the paper describes several active protocols that provide novel network services and discusses the potential impact of these kinds of services on end-to-end application performance.Then it present s and analyze s the performance of an active networking protocol that uses caching within the net-work backbone to reduce load on both servers and backbone routers.
