Replication free rule grouping for packet classification

Xiang Wang, Chang Chen, Jun Li
2013 Computer communication review  
Most recent works demonstrate that grouping methodology could bring significant reduction of memory usage to decision-tree packet classification algorithms, with insignificant impact on throughput. However, these grouping techniques can hardly eliminate rule-replication completely. This work proposes a novel rule grouping algorithm without any replication. At each space decomposition step, all rules projecting on the split dimension form the maximum number of non-overlapped ranges, which
