Abstract The development of router architecture is analyzed, and the fast route lookup and packet classification algorithms for high speed router are researched. The research shows the lookup algorithm for IPv6 route lookup with compression trie has reasonable memory space and fast lookup time. The compositive multi-dimensional packet classification algorithm based on tree divided by value is scalable. It can deal with prefixes match and range match for large rule sets. Two algorithms are suitable for high speed router.
