About queues creating in mininet switch -- just as example: https://github.com/itmo-infocom/nox12oflib/blob/master/src/nox/coreapps/switchqos/test.py
This is our small enhancements of standard mininet UserSwitch class which we use for QoS management simplifying in mininet for CPqD OF 1.2 env-t. 20/02/2013 16:15 -0800, Geetha S wrote: > Thank you for the reply Srinivas.
