Dear Glenn,

The IETF NVO3 Working Group has been developing the requirements for a
Control Plane Protocol between server Hypervisors and Network Virtualization
Edge (NVE) devices in virtualized overlay networks. The current draft can be
found at

This requirements document suggests extending the VDP (VSI Discovery and
Configuration Protocol) protocol specified by IEEE Std 802.1Qbg as a
solution. We would particularly welcome IEEE 802.1 Working Group’s review of
Section 5 of the draft. That section compares the conceptually similar terms
in NVO3 and the VDP context. It also summarizes the potential technical
extension work required for VDP to be used as the control plane protocol
between the hypervisor and NVE.

In view of the progress of this work, we would like to suggest IEEE 802.1
Working Group to use that draft as a base requirement reference for VDP
extensions in the aforementioned context. Please note that the status of this
draft in the IETF, a “Working Group draft”, indicates that the Working Group
considers it an appropriate starting point but it is still subject to change
based on NVO3 WG consensus. While a determination has not yet been made that
there is technical consensus on all the details of the draft, there is
consensus on basing the Hypervisor to NVE protocol on VDP with appropriate

Sincerely Yours,
