High performance and security are hot areas of the research of Internet. How to provide security protection but not decrease the forwarding performance is a hot research topic currently. This paper is based on the research of the high performance security router, a key project of national high technology research and development plan. Operating system (HEROS) of the high performance router BW7000 was developed independently. In order to provide high performance IP packets forwarding, a high performance routing lookup algorithm based on RAM was developed. A novel classification algorithm based on non-collision Hash-Trie-tree and an algorithm based on distributed packet fair queuing with feedback mechanism weve designed and impemented to support QoS control and security management. In order to secure the network, a router security architecture based on distributed key management was proposed.
