TCAM Razor: a systematic approach towards minimizing packet classifiers in TCAMs

  title={TCAM Razor: a systematic approach towards minimizing packet classifiers in TCAMs},
  author={Alex X. Liu and Chad R. Meiners and Eric Torng},
Packet classification is the core mechanism that enables many networking services on the Internet such as firewall packet filtering and traffic accounting. Using ternary content addressable memories (TCAMs) to perform high-speed packet classification has become the de facto standard in industry. TCAMs classify packets in constant time by comparing a packet with all classification rules of ternary encoding in parallel. Despite their high speed, TCAMs suffer from the well-known range expansion… CONTINUE READING
