Hi, we are having some numbers regarding the performance of L3FWD and would like to confirm that they make sense. So, for L3FWD and 1500byte packets we get 120Gbps out of 12x10Gbps ports (so we get full throughput) and for 64byte packets we get 80Gbps. According to Intel documentation [1] these n

I do not know any open source implementation of an efficient LPM. FYI, some data with a commercial one: -> up to 160Mpps, the bottleneck was the IOs, not the CPU. http://www.6wind.com/products/6windgate-protocols/ip-forwarding/ Best regards, Vincent On 24/09/2013 15:53, Jun Han wrote: >

Hello, We are trying to benchmark L3FWD application and have a question regarding the IP lookup algorithm as we expect the bottleneck to be at the lookup. Could someone let us know how efficient the lookup algorithm that L3FWD is using (e.g, LPM)? We are asking because we want to obtain highest L3
