NXM support

[robhoes]

Hi there! Great project! :)

I was wondering whether there are any plans to add support for the Open vSwitch extensions from Nicira (NXM), such as additional matches with masks, multiple tables, and the "learn" action?

Sounds like a great GSoC project!

Well, I might be able to give it a go myself if I get a chance. Sounds like you are open to contributions for this?

Thanks for the kind words, @robhoes. We don't have any immediate plans to support them, but we are open to contributions.

We support OXM from OpenFlow 1.3. Other than learn(), is there a big difference? Can you point to a spec for NXM so we can see what it offers?

[adferguson]

the Nicira extensions have a ton of additional features, some of which have been integrated into recent versions of OpenFlow: http://git.openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=include/openflow/nicira-ext.h;hb=HEAD

NXM and OXM have a few differences. OVS DESIGN file has some coverage: http://git.openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=DESIGN;hb=HEAD

also see the ovs-ofctl man page for info: http://openvswitch.org/cgi-bin/ovsman.cgi?page=utilities%2Fovs-ofctl.8

I am particularly interested in the "learn" action, which is quite powerful. For example, it allows you to do MAC learning, or implement a stateful firewall, on the switch itself.

The tutorial explains it quite well: http://git.openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob;f=tutorial/Tutorial;h=0506a20751efc5eb3ba78b189505d2930f3f6b8a;hb=HEAD

FastKAT folks: another use of network registers?!

Indeed sounds like a network register.

[arjunguha]

yes, totally
