一种可演进的互联网体系结构

An Evolvable Internet Architecture

互联网端到端属性使得运行于主机端的应用层协议易于修改和部署,从而促进互联网通过新应用的竞争不断发展;但是涉及到网络核心层和网络设备(交换机、路由器等)的新协议则在实现和应用上十分困难,阻碍了互联网核心技术的演进。文章提出一种可演进的网络体系结构(EIA)。网络可以通过EIA提供的接口在主机和网络设备上添加新的模块来得到试验和实际部署。不同的用户可以任意选择不同的体系结构,同时用户可以是一种或多种网络体系结构的使用者。人们可以多样化竞争的方式推动互联网的演进。

The end-to-end characteristics of networks enables easy modification and development of applications running on the host. Competition among these applications promotes the development of the Intemet. However, new protocols related to core networking or network equipment （routers, switches etc.） are often hard to successfully implement. This paper proposes an Evolvable Internet Architecture （EIA）. It proposes that new network architectures can plug themselves as new modules into EIA network equipment using the interfaces provided by EIA for experiment and actual development. Different users can independently select network architectures, and at the same time there may be one or more users of network architectures. This diversity and competitiveness promotes the evolution of the network.
