Subject: [ovs-discuss] Setting TCP rwnd value in Open vSwitch

Dear All,

I want to modify value of receiver window field(used for flow control) in the TCP header using OpenFlow rule at Open vSwitch. To make it clear what I am trying to do, lets illustrate this in the following way,

In_port=1, match src_ip=, action:set_tcp_rwnd=10, out_port=2


Controller ryu
OpenFlow 1.3
OVS 2.5.2

Help/Clue would be highly appreciated, If anyone has done similar work. Thanks in advance!

Best regards,
