Abstract

   The document [RFC4908] proposes to rely on multiple Care-of Addresses
   (CoAs) capabilities of Mobile IP [RFC6275] an Network Mobility (NEMO;
   [RFC3963]) to enable Multihoming technology for Small-Scale Fixed
   Networks.  In the continuation of [RFC4908], this document specifies
   a multiple proxy Care-of Addresses (pCoAs) extension for Proxy Mobile
   IPv6 [RFC5213].  This extension allows a multihomed Mobile Access
   Gateway (MAG) to register more than one proxy care-of-address to the
   Local Mobility Anchor (LMA).

1.  Introduction

   Using several links, the multihoming technology can improve
   connectivity availability and quality of communications; the goals
   and benefits of multihoming are as follows:

   o  Redundancy/Fault-Recovery

   o  Load balancing

   o  Load sharing

   o  Preferences settings

   According to [RFC4908], users of Small-Scale Networks can take
   benefit of multihoming using mobile IP [RFC6275] and Network Mobility
   (NEMO) [RFC3963] architecture in a mobile and fixed networking
   environment.  This document is introducing the concept of multiple
   Care-of Addresses (CoAs) [RFC5648] that have been specified since
   then.
