Thank you for your interest in P4 and for subscribing to the P4
announcement mailing list. Today a few quick notes related to P4.

P4 and OVS

P4 appeared in multiple talks at the November Open vSwitch conference. 

 	* Johann Tonsing mentioned P4 in his talk on accelerating OVS.
 	* P4 was discussed during John Fastabend's talk on Flow APIs for
hardware offloads.
 	* Dan Talayco presented Programmable Parsing and P4 to the Open
vSwitch community listing the benefits of supporting programmable
parsing in OVS. This would allow OVS to support newer protocols and
changes to existing ones with greater agility and ease. It would also be
an important step towards supporting P4 and protocol independent
forwarding in OVS.

Slides for all the talks are available at:
