This paper introduced the development of routing protocol , isolation technology , and then introduced the research scope of isolation technology around the world . and then analyzed the ospf ( open shortest path first ) protocol , introduced the routing hierarchy feature of it , analyzed the diffuse process , and the theory of how it works 本文介绍了路由协议、隔离技术的发展,并介绍了国内外在隔离技术中的研究方向,接着分析了ospf路由协议,介绍了ospf分层路由的概念,详细分析了ospf路由协议的扩散过程和工作原理。
Open Shortest Path First (OSPF) is a link-state routing protocol for Internet Protocol (IP) networks. It uses a link state routing algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS).
