FPGA implementation of modular architecture for packet classification using field split algorithm

Packet classification has proved to be an important challenge in network processing. It requires comparing each packet with rules and forwarding the packet according to the highest priority matching rule. The criteria are comprised of a set of rules that specify the content of specific packet header fields to either software or hardware. Packet classification is widely used as a core function for various applications in networking. So increase demands in throughput and reduce latency. Also the performance of today's packet classification solutions depends on the rule sets. In this paper, we propose a modular Bit-Vector (BV) based architecture to perform high-speed packet classification on Field Programmable Gate Array (FPGA) Matching packets with some predefined rules using XillinxISE13.2 software.
