Hi Iwase,
Let me clarify the use case a little bit more.
Lets say, you run on Linux
# ethtool -S enp1s0
you will get a bunch of NIC stats. I want to wrap the same in an openflow
message and send it to a Ryu controller running my special Ryu App which
will connect to this client and
- ask for
http://ryu.readthedocs.io/en/latest/ofproto_v1_3_ref.html#ryu.ofproto.ofproto_v1_3_parser.OFPPortStatsRequest
- and I want to wrap the NIC stats and send response via
http://ryu.readthedocs.io/en/latest/ofproto_v1_3_ref.html#ryu.ofproto.ofproto_v1_3_parser.OFPPortStatsReply
So, I want to use the Ryu Openflow API to do this.
Does this help?
Thanks
