      Discovery Of Restconf Metadata for Source-specific multicast
                       draft-ietf-mboned-dorms-00

Abstract

   This document defines DORMS (Discovery Of Restconf Metadata for
   Source-specific multicast), a method to discover and retrieve
   extensible metadata about source-specific multicast channels using
   RESTCONF.  The reverse IP DNS zone for a multicast sender's IP
   address is configured to use SRV resource records to advertise the
   hostname of a RESTCONF server that publishes metadata according to a
   new YANG module with support for extensions.  A new service name and
   the new YANG module are defined.
