摘要/Abstract

摘要： OSPF是目前在全球范围应用最多的域内路由协议,但是IS-IS 协议的日益流行使其优点也备受关注。对OSPF和IS-IS两种域内路由协议在工作机制、收敛性、可扩展性和安全性方面进行了详细比较。理论分析和实验结果表明,OSPF和IS-IS都具有快速收敛和安全可靠的特性,OSPF具有更丰富的路由策略、多种区域类型、协议数据包和电路类型,更适合中小型网络和企业使用。IS-IS相对简单、稳定,可扩展性好,在巨量路由条目的情况下,IS-IS的处理比OSPF更有效率,更适合网络运营商和ISP部署。

Abstract: Currently,OSPF is the most widely used domain routing protocol in the world,but the advantages of IS-IS are increasingly getting more attention.This article compares OSPF and IS-IS on the working mechanism,the convergence,scalability and security in detail.The practical analysis and experimental results show that OSPF and IS-IS have the advantages of fast convergence and safety features.OSPF has more abundant routing strategies,variety of regional types,PDU and circuit types.OSPF is more suitable for small and medium-sized network and enterprise using.IS-IS is relatively more simple,stable and scalability.In the massive route objective circumstances,IS-IS is more efficient than OSPF and more suitable for deployment of network operators and ISP.

Key words: Domain routing protocol,IGP,OSPF,IS-IS
