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.
