[pox-dev] Statistics module

[Kouvakas Alexandros]

Pretty nice with this module.
I would like to ask some more questions. First, where can I find some
explanation for each parameter for example for FlowStatsReceived or for
PortStatsReceived ?
Moreover what exactly do we consider as web traffic. As I noticed pings
between nodes/VMs are not considered as web traffic.

Finally, is there any method by using POX modules, to measure the time that
a packet needs to travel from the source to the destination including the
way pass from the controller.
For example, when the flow table is empty and I ping from one node to
another the first packet needs at least the double time than all the other
packets that follow. That means that the first packet "passes" from the
controller. So in my case I want to measure these parameters comparing for
example to the size of the network. Also I will differenciate the size of
the packets to study how the controller reacts in such cases.

Thanks a lot!
Alexandros
