[ovs-discuss] ct_state and tcp sessions

*OVS version: 2.70*

Howdy!

*Goal:* instantiate a flow(s) based on completion of tcp 3-way handshake
and have those flows live ONLY as long as the respective tcp session
exists. Once the tcp session has ended, I want the flow(s) to be removed. I
don't want the flows to be removed if the respective hosts stop talking for
whatever reason for say 5 minutes. They would be removed only in the event
the tcp session is terminated.

Can I use ct_state and associated conn-track to accomplish this?

Any ideas?

Thanks!

Steve
