In order to provide more value added services, the Internet needs to classify packets into flows for different treatment. High performance packet classification algorithms for large classifiers and edge classifiers are highly demanded.
In this paper, we will describe a new algorithm for packet classification that makes use of bits distribution features. It is a high level classification method. It always takes the bits from every dimension into account, instead of constraining the search process in some of the dimensions at every stage. The experiments provide the evidence that it has outstanding performance even for large edge classifiers. It is also scalable to IPv6.
