Packet classification is a crucial technique for secure communication and networking. Security tools and internet services use packet classification technique which involves checking of packets against predefined rules stored in a classifier. The performance of the available software solutions of classification is not desirable and efficient for wire speed processing in high speed networks. Ternary Content Addressable Memory (TCAM), Bit-Vector (BV), field split bit vector (FSBV).In this paper, simple and memory efficient approach for packet classification has been proposed using Xnor gate instead of using lookup tables called XnorBV approach. Packet header fields of Internet protocol (IP) addresses and protocol layer are classified using Xnor gate against predefined ruleset which also support ternary bit pattern of ‘1’, ‘0’ and ‘*’ while port numbers of packet header support range match by comparing port numbers against lower bound and upper bound. The proposed XnorBV architecture is independent of ruleset feature and supports multiple dimension classification.
