Hi,

We have updated the VXLAN-SOE draft according to earlier comments. Now it is fully compatible with VXLAN-GPE. And some examples are added for better understanding.

A prototype is also implemented here (patch based on Open vSwitch):
https://github.com/hzhou8/openvswitch/commit/9a7deb8b432ce83a9c09d7d4ff85fa050f7dd2be

netperf TCP_STREAM test result between a pairs of VMs on hosts with 10G interfaces:

Before the change: 2.62 Gbits/sec
After the change: 6.68 Gbits/sec
Speedup is ~250%.

The patch attracted some interests in OVS community, but since this RFC draft is in very early stage so it is regarded as inappropriate by Jesse to apply the change to OVS tree.
The discuss mail-thread: 
http://openvswitch.org/pipermail/discuss/2014-May/013981.html
http://openvswitch.org/pipermail/discuss/2014-May/013898.html

So we would like to request a review here by NVO3/TOFOO groups and VXLAN authors: is this VXLAN extension is worth formally put into VXLAN as a standard, so that more people can benefit from it?

Best regards,
Han

        Title           : Segmentation Offloading Extension for VXLAN
        Authors         : Han Zhou
                          Chengyuan Li

Abstract:
   Segmentation offloading is nowadays common in network stack
   implementation and well supported by para-virtualized network device
   drivers for virtual machine (VM)s. This draft describes an extension
   to Virtual eXtensible Local Area Network (VXLAN) so that segmentation
   can be decoupled from physical/underlay networks and offloaded
   further to the remote end-point thus improving data-plane performance
   for VMs running on top of overlay networks.
