Abstract:

In this paper we present IMSS: IP Multicast Shortcut Service for ATM networks. IMSS pursues the ``shortcut'' routing paradigm in order to exploit the underlying ATM QoS and native routing mechanisms in the optimal way.

IMSS is built on top of CONGRESS (CONnection oriented Group-address RESolution Service). CONGRESS is an efficient native ATM protocol for resolution and management of multicast group addresses in a large ATM cloud. CONGRESS resolves multicast group addresses and maintains their membership for applications. It is not designed to handle the applications' data-exchange.

An IMSS extension at a multicast router uses the group membership information that it receives from CONGRESS, in order to open ATM connections that bypass (``shortcut'') the IP routing mechanism.

In this work we deal primarily with the implementation of IMSS. CONGRESS' design, however, will also be provided due to the non-triviality of group address resolution and maintenance problems that it addresses.
