When what reaches a limit? The flow table size? Or are you still talking about queues? If you mean queues, the answer is no. OVS and OpenFlow are not meant for queue manipulation. -- Murphy > On Fri, May 3, 2013 at 3:32 AM, Murphy McCauley <murphy.mccau...@gmail.com> > wrote: > It sounds like you're talking about monitoring and manipulating the contents > of queues, which is a very fine-grained operation that must operate at very > small timescales.
