Abstract— A Scalable and Modular Architecture for High-Performance Packet Classification. Packet classification is widely used as a core function for various applications in network infrastructure. With increasing demands in throughput, performing wire-speed packet classification has become challenging. Also the performance of today’s packet classification solutions depends on the characteristics of rulesets. In this work, we propose a novel modular Bit-Vector (BV) based architecture to perform high-speed packet classification on Field Programmable Gate Array (FPGA). We introduce an algorithm named StrideBV and modularize the BV architecture to achieve better scalability than traditional BV methods. Further, < Final Year Projects > we incorporate range search in our architecture to eliminate ruleset expansion caused by range-to-prefix conversion. The post place-and-route results of our implementation on a state-of-the-art FPGA show that the proposed architecture is able to operate at 100+ Gbps for minimum size packets while supporting large rulesets up to 28 K rules using only the on-chip memory resources. Our solution is ruleset-feature independent , i.e. the above performance can be guaranteed for any ruleset regardless the composition of the ruleset.
