[Gregory Elkinbard <gelkinbard@xxxxxxxxxxxx>]

Hi guys,
the key features that I am looking for are actually
1) efficient operation at 40 gigabit/s throughput (2x10 gig ethernet
links going in both directions). This will require 2-3 cores
2) partial mesh support. As I understand older ovs will retransmit all
broadcasts and multicasts to all nodes regardless of whether they need
them or not in GRE and VXLAN modes. Per Andrew W. this needs OVS 2.1
or greater.

+ Alexander S. as the platform team is also looking at OVS and performance.

Thanks
Greg
