The backbone network throughput has climbed up to 40Gbps, it demands a high-speed pattern matching algorithm. In this paper, we apply Half byte matching and SRAM-based Expansion into the traditional TCAM lookup algorithm, to meet accuracy requirements. Theoretical analysis and experimental results show that, the HBS-TCAM algorithms can significantly improve the service identification accuracy, thus enhancing the performance of TCAM lookup system.
