Virtual Machine Mobility Solutions for L2 and L3 Overlay Networks
draft-ietf-nvo3-vmm-05
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 VM (virtual machine) moves from Old NVE to the New NVE. For
Layer 3, it is based on address and connection migration after the
move.
