Thank you Murphy, I read these points and worked on queue and port stats. (ofp_queue_stats_request, and ofp_queue_stats) (ofp_port_stats and ofp_port_stats_request)
To print the queues and ports stats including all packets sent through them. I've this simple experiment, two host (h1 and h2) and one switch. The BW of link (h1-s1) and link (h2-s1) is 10Mbps and 5 Mbps respectively. h1 --------- s1 ---------- h2 In my experiment, I create two queues for each interface (s1-eth1 and s1-eth2). One queue (q0) is for TCP traffic while the q1 is for other traffic. I would like to ask how to measure real time queueing, so the controller has information about how many packets in each queue at particular time.

You might read the "OpenFlow in POX:OpenFlow Messages:ofp_stats_request - Requesting statistics" section in the POX wiki manual. -- Murphy On Sep 11, 2013, at 7:35 PM, Ali Al-Khamis <[email protected]> wrote: Hi all, > > >I am new in POX controller.
