Technical Summary

In a Split Network Virtualization Edge (Split-NVE) architecture, the
   functions of the NVE (Network Virtualization Edge) are split across a
   server and an external network equipment which is called an external
   NVE.  The server-resident control plane functionality resides in
   control software, which may be part of hypervisor or container
   management software; for simplicity, this document refers to the
   hypervisor as the location of this software.

   Control plane protocol(s) between a hypervisor and its associated
   external NVE(s) are used by the hypervisor to distribute its virtual
   machine networking state to the external NVE(s) for further handling.
   This document illustrates the functionality required by this type of
   control plane signaling protocol and outlines the high level
   requirements. Virtual machine states as well as state transitioning
   are summarized to help clarify the protocol requirements.

Working Group Summary

   The document was developed to provide input from the IETF community to help guide
   the development of extensions for VDP (VSI Discovery and Configuration protocol) that
   took place in parallel at the IEEE. The draft also describes how VDP is applicable 
   to these split-NVE scenarios. 

   There are no IPR declarations on the draft . 

Document Quality

   No concerns about the quality of the document. It represents 
   WG consensus, and it has been widely reviewed and discussed on the list over a 
   number of years. There was also close interaction between NVO3 and the IEEE during the 
   development of the draft and VDP, including liaisons and presentations at NVO3 WG 
   meetings by IEEE participants.
