PIM-SM configuration and scalability on satellite unidirectional links

Abstract

This paper considers satellite unidirectional links having a large number of nodes and discusses the PIM-SM configuration on these links if there is no separate multicast routing information base. Looking closely at the PIM-SM specification documents, we propose a PIM-SM configuration that enables multicast traffic to flow on unidirectional links. We also discuss the scalability of PIM-SM on satellite unidirectional links. We expect that the join/prune message suppression strategy is an important element for scaling PIM-SM on these links.
