Hello everyone.
I want to add some TCP flag based rules as flow table entries.
Like, adding a rule for TCP Syn and TCP Ack on flow table entries so that i
can track who can initiating tcp connection request to whom (based on
policy).
After searching about this, i end up with a confusion whether OFP v1.3
allows it or not. Because some old threads state that it is not supported
and new threads state that it can be possible by using extensible match
fields of OFP Match.
now the question is : is it possible to add flow table rules that match
inner tcp control bits ? if yes, how ?
if no ? is it because of openflow's support is limited to only addresses
and MPLS- VLAN fields ? are there any alternatives ?
Thank you so much.
