    Network Virtualization NVE to NVA Control Protocol Requirements
                   draft-ietf-nvo3-nve-nva-cp-req-01

Abstract

   The document "Problem Statement: Overlays for Network Virtualization"
   discusses the needs for network virtualization using overlay networks
   in highly virtualized data centers.  The problem statement outlines a
   need for control protocols to facilitate running these overlay
   networks.  This document outlines the high level requirements to be
   fulfilled by the control protocols related to building and managing
   the mapping tables and other state information used by the Network
   Virtualization Edge to transmit encapsulated packets across the
   underlying network.

1.  Introduction

   "Problem Statement: Overlays for Network Virtualization"
   [I-D.ietf-nvo3-overlay-problem-statement] discusses the needs for
   network virtualization using overlay networks in highly virtualized
   data centers and provides a general motivation for building such
   networks.  "Framework for DC Network Virtualization"
   [I-D.ietf-nvo3-framework] provides a framework for discussing overlay
   networks generally and the various components that must work together
   in building such systems.  The reader is assumed to be familiar with
   both documents.

   Section 4.5 of [I-D.ietf-nvo3-overlay-problem-statement] describes
   three separate work areas that fall under the general category of a
   control protocol for NVO3.  This document focuses entirely on those
   aspects of the control protocol related to the building and
   distributing the mapping tables an NVE uses to tunnel traffic from
   one VM to another.  Specifically, this document focuses on work areas
