Abstract

   This document describes the Multicast Address-Set Claim (MASC)
   protocol which can be used for inter-domain multicast address set
   allocation.  MASC is used by a node (typically a router) to claim and
   allocate one or more address prefixes to that node's domain.  While a
   domain does not necessarily need to allocate an address set for hosts
   in that domain to be able to allocate group addresses, allocating an
   address set to the domain does ensure that inter-domain group-
   specific distribution trees will be locally-rooted, and that traffic
   will be sent outside the domain only when and where external
   receivers exist.
