Conference paper (peer-reviewed)abstract
- This paper reports on the design of an IPv4 prefix lookupengine that supports 166 million lookups per second, andan estimated 850k prefix entries. It also supports dynamictable update operations that can be issued from anexternal controller. The design employs a prefix searchalgorithm that is fine-tuned for hardware implementation.It takes advantage of pipelining and utilizes one FPGAchip and seven ZBT® SRAM chips. We have implementedthis engine as an HDL core in Verilog.
