Packet Classification Using Pipelined Two-Dimensional Multibit Tries ∗

We propose heuristics for the construction of fixed- and variable-stride two-dimensional multibit tries. These multibit tries are suitable for the classification of Internet packets using a pipelined architecture. The pipelined two-dimensional multibit tries constructed by our proposed heuristics are superior, for pipelined architectures, to two-dimensional multibit tries constructed by the best algorithms proposed for non-pipelined architectures
