Hi Govind,
I think your app needs some modification.
1. The method name "_packet_in_handler" is duplicated.
If you need to add another method for Packet-In,
Please change the method name.
2. Import module of "tcp" packet lib is missing.
+ from ryu.lib.packet import tcp
3. If the proce

Hi Govind,
Did you get any error messages from ryu-manager?
If not, first, please check OpenFlow version of your swtich.
("simple_switch.py" is OpenFlow 1.0 App.)
And, by capturing packet with Wireshark, you can get the helpful information
for debug.
(e.g. whether Controller sends FlowMod messag
Hi Yusuke,
Thanks for the suggestion, I tried the following code in "simple_switch.py"
however when I send TCP packets from h1 to h2 using iperf in mininet, the
packets are getting transmitted but the flows are not getting written in
the switch table:
@set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_
Hi Govind,

You can parse the Packet-In data and get the port number by using packet
library.
e.g.)
@set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER)
def _packet_in_handler(self, ev):
msg = ev.msg
Hi yusuke,
Thanks fir the info however can you please specify how to implement the
following scenario:
1. Iperf client send the tcp message on port 8000
2. Iperf server receives the tcp port through ovs
3. Ryu asks the ovs to write the flow with default values
4. If port numbe is greater than 5
Hi experts,
I am working on an application which works as follows:
1. The switch gets the first TCP packet
2. It sends the packet to the controller
3. The controller invokes an application which was looking for TCP packets.
4. The application sets a extended idle timeout (fore ample 1 hour) an
