Hi Tomas,
Because the contained "data" in the PACKET_IN message is an Ethernet frame
message, I guess it is difficult to implement such feature...
For example, you need to open another socket on tap interface for example, then
open "data" in PACKET_IN messages -> extract TCP payload -> forward them to that
socket.
For an alternative way, how about adding another port on your switch to which
your web server connecting?
Ryu Web Sever
| |
+---+ +---+
| |
Host A ---- switch ---- Host B
With this approach, you don't need to analyze "data" in PACKET_IN messages, just
need to install flows for Web Server-Hosts communication.
Thanks,
Iwase

Hello,
I’m working on my phd thesis and I need to establish a TCP connection with a
controller. Is there anyone, who already implemented a full TCP state diagram
in RYU to handle incoming TCP connections towards the forwarders? I’m
implementing a minimalist web server on a forwarders, so I need to be able to
establish a TCP connection with the controller via the forwarders using just
only PACKET_IN and PACKET_OUT messages.
By TCP state diagram I mean the same way as the controller responds with ICMP
or ARP messages.
