Architecture and Framework for IPv6 over Non-Broadcast Access

This document presents an architecture and framework for IPv6 access networks that decouples the network-layer concepts of Links, Interface, and Subnets from the link-layer concepts of links, ports, and broadcast domains, and limits the reliance on link-layer broadcasts. This architecture is suitable for IPv6 over any network, including non-broadcast networks, which is typically the case for intangible media such as wireless and virtual networks such as overlays. A study of the issues with IPv6 ND over intangible media is presented, and a framework to solve those issues within the new architecture is proposed.
