IPv6 Home Networking Architecture Principles
Abstract
This text describes evolving networking technology within residential
home networks with increasing numbers of devices and a trend towards
increased internal routing. The goal of this document is to define a
general architecture for IPv6-based home networking, describing the
associated principles, considerations, and requirements. The text
briefly highlights specific implications of the introduction of IPv6
for home networking, discusses the elements of the architecture, and
suggests how standard IPv6 mechanisms and addressing can be employed
in home networking. The architecture describes the need for specific
protocol extensions for certain additional functionality. It is
assumed that the IPv6 home network is not actively managed and runs
as an IPv6-only or dual-stack network. There are no recommendations
in this text for the IPv4 part of the network.
