Research on HBS-TCAM Algorithm in 40Gbps Business Management and Control System

40Gbps business management and control system for high-speed pattern matching algorithm is proposed by a very high demand.This paper proposes HBS-TCAM algorithm to enhance the performance of TCAM lookup system,based on half byte matching and SRAM-based Expansion,to meet accuracy requirements.Theoretical analysis and experimental results show that the HBS-TCAM algorithms can significantly improve the service identification accuracy,thus enhance the performance of TCAM lookup system.
