     Virtual Machine Mobility Solutions for L2 and L3 Overlay Networks
                          draft-ietf-nvo3-vmm-12

Abstract

   This document describes virtual machine mobility solutions commonly
   used in data centers built with overlay-based network. This document
   is intended for describing the solutions and the impact of moving
   VMs (or applications) from one Rack to another connected by the
   Overlay networks.

   For layer 2, it is based on using an NVA (Network Virtualization
   Authority) - NVE (Network Virtualization Edge) protocol to update
   ARP (Address Resolution Protocol) table or neighbor cache entries
   after a VM (virtual machine) moves from an Old NVE to a New NVE.
   For Layer 3, it is based on address and connection migration after
   the move.
