[ovs-dev] [PATCH 1/2] DPI plugin addition proposal v2

[Justin Pettit]

It looks like this patch still slow-paths packets until the classification is done.  As I stated last time[1], this is a non-starter because of the impact it will have on performance.  As such, I'm not going to review any patches or comment on future ones that do this.  If you want to integrate with OVS, you must find a way to classify the packets in the datapath.

If that's not possible, then I would recommend creating a local controller to which you send packets for classification.  You can have it program flows that send Packet-Ins to it until the classification is done.  Once you've determined the classification, you can push down a flow that applies the policy into the fast-path.  If you want to work with other OpenFlow controllers, you'll need to coordinate with them or create a Flowvisor-like proxy, though.
