Naresh Soni, Nicholas Richardson, Lun-Bin Huang, S. Rajgopal, G. Vlantis · 2003
This paper describes the NPSE, a high-performance SRAM-based network packet search engine which has the primary application of supporting IPv4 and IPv6 forwarding. It is based on a high-speed hardware implementation of a tree-based storage and retrieval algorithm, which is memory and power-efficient compared to traditional CAM-based look-up methods.
