Hi Raghu,
Please keep mailing-list.
You mean just the elapsed time of sending FlowMod messages at Ryu side, I
guess you can measure it by capturing (tcpdump, wireshark) the packets at
Ryu's host.
But, if you mean the elapsed time from the start of sending FlowMod to the
last FlowMod installation, the problem is complex...
Just an idea, with the following topology, how about measure the elapsed
time from the first FlowMod to the time when the packets arrival to
interface B.
+---------+
| Ryu (IF-A) <----+
| (IF-B) <----+
+---------+ |
| |
| |
V |
Host------->Switch------------+
Host: sending continuous packets.
Switch: forwarding packets to interface A of Ryu controller until the last
FlowMod will receive, and if the last FlowMod receive, send packets to
interface B.
Ryu: sending required FlowMod messages.
Then, the required time should be:
(the time of the fist FlowMod) - (the of the fist packet at interface B)
Thanks,
Iwase
