[Ryu-devel] Sending Packet out from Ryu controller to Ryu controller

2018-03-27 Thread emi.hacker via Ryu-devel 
Hello all,

I built my topology to send Table-Miss Packets from (S1 or S2 ) to C2 through 
S3, I need to send the same packet from C2 to C1, and then C1 installs the 
instruction into S1.




C1                             C2 |   \                              |S1 S2 
S3

Is there any previous example !!?



Thanks in advance
