Hi, Billy I’d like to share the commands and OVS bridge configuration for micro-bursts. If you have any questions, please send email. ;-)
Moreover, I’d like to talk to a way how to access VSPERF project. Can I send e-mail to Maryam Tahhan ([email protected]<mailto:[email protected]>) for the comments or the presentation?
