Virtual Machine Mobility Protocol for L2 and L3 Overlay Networks
draft-ietf-nvo3-vmm-03.txt
Abstract
This document describes a virtual machine mobility protocol commonly
used in data centers built with overlay-based network virtualization
approach. For layer 2, it is based on using a Network Virtualization
Authority (NVA)-Network Virtualization Edge (NVE) protocol to update
Address Resolution Protocol (ARP) table or neighbor cache entries at
the NVA and the source NVEs tunneling in-flight packets to the
destination NVE after the virtual machine moves from source NVE to
the destination NVE. For Layer 3, it is based on address and
connection migration after the move.

1. Introduction
Data center networks are being increasingly used by telecom operators
as well as by enterprises. In this document we are interested in
overlay-based data center networks supporting multitenancy. These
networks are organized as one large Layer 2 network geographically
