Method of High Performance Packet Classification Using TCAM and Apparatus Thereof

摘要

A high-performance packet classification method using A TCAM(Ternary Content Addressable Memory) and an apparatus thereof are provided to achieve high-speed flow control by classifying composite traffic through a TCAM, appointing a hash value to associated data, and managing it as single flow information. A packet classification apparatus comprises a packet receiving part(10), a 5-tuple(11), a packet buffer(12), packets(13), a TCAM storage part(14), and a packet transmitting part(15). The packet classification apparatus extracts the 5-tuple(11) for traffic classification from the packet buffer(12) in order to classify the packets delivered through the packet transmitting part(15). The packet classification apparatus classifies the packets(13) according to the classification rules stored in the TCAM storage part(14) and transfers them to the packet receiving part(10).
