           Homenet Naming and Service Discovery Architecture
                  draft-ietf-homenet-simple-naming-03

Abstract

   This document describes how names are published and resolved on
   homenets, and how hosts are configured to use these names to discover
   services on homenets.  It presents the complete architecture, and
   describes a simple subset of that architecture that can be used in
   low-cost homenet routers.
