It sounds very interesting. I will take a look on the link you mentioned
You wrote down that "Soon we will be releasing a pre-configured VM that
..." When are you expecting this release to be available? Can we have
something to play with before the formal release is aired?
Thanks a lot,

Simhon, I know that you are asking about OVS, but in case you want to
experiment with the flow metering features introduced in OF1.3, here is
an implementation based on the reference switch design:
There is also a companion NOX v1.3 to implement the corresponing app, or
you can use the dpctl commands, e.g., to install a 10 Mbit metering
dpctl tcp:<switch-host>:<switch-port> meter-mod
Soon we will be releasing a pre-configured VM that including Mininet
2.0, Wireshark, and oftest in addition to the 1.3 switch and NOX.
BTW, Mininet 2.0 works very nicely to play with QoS features since they
added neat BW and delay capabilities per link.
One caveat on the switch above is that the current implementation
forwards only around 200 Mbps, notably behind OVS performance. Work
towards better performance will be done in Q1 of 2013. The current
token-bucket implementation for rate limiting works but better accuracy
shall be pursued as well during the next months.
