Hi Justin, I knew that you wouldn’t accept the patch (same hooking place, same impact on ovs-vswitchd), but I posted this patch anyway to get feedback on AXM concept that has been demonstrated at the ONF forum (http://youtu.be/jkbkvX2B_kI): how to use and present L4-L7 information at the OpenFlow level.
I’m trying to find a proper way, without success so far, to add the L4-L7 in the Linux datapath, even if this wouldn’t work with HW switches datapath. Adding new AXM fields in the sk_buff or hijacking existing fields doesn’t seems viable ;-) Thanks for your architecture suggestion with a local controller, I’ll work on it. In between, please don’t hesitate to provide feedback on AXM concept/semantic/use cases. I plan to use this patch to progress on this side until I get a datapath based implementation.
