                    Home Networking Control Protocol
                       draft-ietf-homenet-hncp-08

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 which supports routing based on both source and
   destination address.
