Home Networking Control Protocol
Abstract
This document describes the Home Networking Control Protocol (HNCP),
an extensible configuration protocol, and a set of requirements for
home network devices. HNCP is described as a profile of and
extension to the Distributed Node Consensus Protocol (DNCP). HNCP
enables discovery of network borders, automated configuration of
addresses, name resolution, service discovery, and the use of any
routing protocol that supports routing based on both the source and
destination address.
