Just as a data point: we are using POX (the latest from GitHub) and Pantou on the TP-Link (v1.8) and the Mikrotik Routerboard 450g with no problems. Maximum throughput on the RB450g is about 50Mbps, on the TP-Link it's about 6Mbps.
I noticed similar problems when using the version of POX that came bundled with the Mininet VM image, but the current git HEAD works fine. -Russ On Wed, Oct 17, 2012 at 11:54 AM, Yiannis Yiakoumis <yiann...@stanford.edu>wrote: > Yes.
