Internet骨干网间的交互连接机构及其实现

INTERNET EXCHANGES AND NETWORK ACCESS POINTS AND THEIR IMPLEMENTATION

美国Ｉｎｔｅｒｎｅｔ的通信基础设施和骨干网间交互连接机构经历了一个不断发展演变的过程，从早期的节点交换系统和Ｉｎｔｅｒｎｅｔ信息交换机构，发展到目前的网络接入点（ＮＡＰ）和路由选择仲裁系统（ＲＡ）。本文简要介绍了以上技术的发展过程、基本原理以及实现实例，并对在我国的应用进行了讨论。

The U. S. Internet infrastructure and information exchange facilities between backbone networks have evolved from early Nodal Switch Systems and Information eXchange (IX) to current Network Access Point (NAP) and Routing Arbiter (RA). In this paper, we discuss briefly the history of the development of these techniques and the basic concepts and implementation approaches of Internet eXchanges and Network Access Points. Their application in China is discussed.
