Re: [ovs-discuss] Maximum number of Patch port between bridges

2016-07-04 Thread Levente Csikor
Yepp, Ben has right. There are a bunch of performance analyses on the Internet that presents the throughput of software based switches, like OVS, using multiple cores. If your traffic is really simple (like a packet generator's simple pattern, i.e., when all header information are the same for

Hi Ben, Thanks for the information. This is exactly what I was looking for. My implementation involves around 3K dynamic MACs. Couple of questions, 1. MAC eviction on table full. I took a look at NORMAL action Mac learning code. It had implemented MAC eviction by giving fair share of entries fo

Hi Levente, Thanks a lot for spending your time in figuring this! I was looking for around 1000 ports between bridges. I also tried something similar, 2500 ports between two bridges. It became very slow, even the show and dump commands became show. I was also using Intel E5 series. Took an alte

Hi, I did not find any documented limit about the number of patchports, so I wrote a simple script, which adds a predefined number of patchports and some dummy rules into the flow tables to actually have some reason for the whole stuff. First, I tried to add 100 and 1000 patchports between t
