Hello,
 In my academic project i'm applying some wan optimization techniques with SDN. (I'm using Floodlight controller with mininet virtual topology). Now that i have arrived to compression, i would like to ask you some questions.

i want to do something like this:
Host A <-------> OpenFlowSwitch(S1) <----anything----> OpenFlowSwitch(S2) <-------> Host B
i want the compression/decompression to be on the switches level(S1,S2) and not on hosts.

1) How do i create  virtual interfaces rohc0 between the switches? I am confused because the installation and configuration here is done on hosts and not the switches  http://rohc-lib.org/wiki/doku.php?id=rohc-tunnel
2) Is there a specific advantage for doing ROHC using the centralized control provided by SDN ?
3) Are there any specific requirements for the switches to support ROHC ?

sorry for these questions as i'm new this environment. Thanks in
advance.

Johnny
