     Virtual Machine Mobility Solutions for L2 and L3 Overlay Networks
                          draft-ietf-nvo3-vmm-15

Abstract

   This document describes virtual machine (VM) mobility solutions
   commonly used in data centers built with an overlay 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 network.

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