Hi, In Mininet, I am using OVSSwitch for creating the switches in a Mininet topology. I am using OVS 2.1.0 and there is no controller attached as I am setting up the flows manually.
I have a question about the switch startup time, which gets progressively slower as the number of switches increase. As a rough estimation, after about 200 switches, it takes 1-1.5 seconds to create a switch which is not horrible but I was hoping this would be parallized? I asked this question on the mininet-discuss mailing list earlier [0], where I was told that the bottleneck is OVS and that to speed up the switch startup time, the possible solutions were: "batching OVS commands, using multiple ovsdb instances, and asynchronous startup". So my question is basically: how do I decrease the switch startup time or perhaps parallelize it? (The reason I am running these many switches is that I am working on a Modelnet-like emulator, where we are replacing the Modelnet FreeBSD core with Mininet + OVS. The goal is to emulate the Tor network by running as many switches as we can.)
