Subject: Re: [Ryu-devel] how to connect to another tcp server in ryu
application?
Hi
Look at this example.
It was suggested by Iwase and I used it to trigger & catch event and it is very
useful.
Hope it helps ...
Kind regards

Yes, I agree with you.
Usually I use twisted to send and receive tcp message, and twisted is also
driven by event.
But I did not know how to integrate ryu and twisted together.
So I have no idea about receiving data using tcp socket.
Thanks.

Maybe, it concerns about network programming using python.

Thanks for your reply.
Yes, I can connect to tcp server.
But I do not know how to receive the message sent from that tcp server and
handle this message.
I only know how to sending message to tcp server.
So can you give me some advices?
Thanks.

Ryu App is driven by the event. So, it depend on what you want to do when
receiving event.
For example. you can connect TCP server when receiving PACKET-IN.
@set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER)
def _packet_in_handler(self, ev):# establish TCP connection with the TCP server.

Hi all,
I write a RYU application, and several openvswitch connect to it.
class OVSRouter(app_manager.RyuApp):
OFP_VERSIONS = [ofproto_v1_3.OFP_VERSION]
def __init__(self, *args, **kwargs):
super(OVSRouter, self).__init__(*args, **kwargs)
And I run this application using ryu-manager.
At the same time, I want the ryu controller connecting to another TCP server,
acting as a client, and receive data message from that server.
I didn't know how to achieve this. Does anyone have any ideas?
Thanks!
