A novel design for IP packet forwarding based on a new ternary content-addressable-memory configuration offers an efficient hardware solution for the longest-prefix matching problem in Internet routers. The architecture has lower update complexity, lower cost, and shorter search latency compared to the conventional TCAM structure.
