Group communication services are most efficiently implemented on the
lowest layer available.  However, as the deployment status of
multicast distribution largely varies throughout the Intenet,
globally operational group solutions are frequently restricted to
using a stable, upper layer protocol controlled by the application
itself.  This document describes a common multicast API that serves
the requirements of data distribution and maintenance for multicast
and broadcast on a middleware abstraction layer, suitable for
transparent underlay and overlay communication.  It proposes and
discusses mapping mechanisms between different namespaces and
forwarding technologies.  Additionally, it describes the application
of this API at gateways operating between current multicast instances
throughout the Internet.
