Abstract

This memo provides an analysis of the architectural aspects of multi-homing support for the IPv6 protocol suite. The purpose of this analysis is to provide a taxonomy for classification of various proposed approaches to multi-homing. It is also an objective of this exercise to identify common aspects of this domain of study, and also to provide a framework that can allow exploration of some of the further implications of various architectural extensions that are intended to support multi-homing.
