Binary search on levels using a Bloom filter for IPv6 address lookup

Abstract

This paper proposes a new IP address lookup using a Bloom filter. The proposed algorithm is based on binary search on trie levels, and a Bloom filter pre-filters the levels which do not have matching nodes in performing the binary search on levels. Hence the number of memory access which affects the search performance is greatly reduced. Simulation result shows that an IPv6 address lookup can be performed with 1--3 memory accesses in average for an IPv6 routing data set with 1096 prefixes.
