Here's one you missed: http://www.projectfloodlight.org/indigo/ If you're only interested in stuff that goes on iron, openvswitch is out - it's pure software meant to run on hypervisors -Ed -----Original Message----- From: NANOG [mailto:nanog-bounces@nanog.org] On Behalf Of Hank Nussbacher Sent: Tuesday, January 9, 2018 2:18 AM To: nanog@nanog.org Subject: Comparison of freeware open source switch software? I have seen numerous comparisons and RIPE presentations on performance issues of BIRD vs Quagga vs FRR. I am looking for the same thing for freeware switch software. Has anyone done a feature comparison between: http://openvswitch.org/ https://www.openswitch.net/ https://cumulusnetworks.com/products/cumulus-linux/ ...any other I am missing... I am familiar with: http://packetpushers.net/open-networking-cheat-sheet/ https://www.networkworld.com/article/2919599/cisco-subnet/clearing-the-fog-a... so to clarify I am interested only in bare-metal or whitebox swicthes and freeware, open source software. And even better - has anyone done a benchmark to see which performs best? Thanks, Hank
