[pox-dev] Getting flow statistics from a switch on controller

[Murphy McCauley]

A good starting point might be "Example - Web Flow Statistics" in the POX manual.

As far as uniquely identifying a flow, the original idea was to use the match itself (since it certainly should identify the flow).  There's also a flow "cookie".  In OpenFlow 1.0, this was only useful in very limited contexts, but has become more useful with Nicira extensions and higher versions of OpenFlow.
