A Reliable Transport Mechanism for PIM
Abstract
This document defines a reliable transport mechanism for the PIM
protocol for transmission of Join/Prune messages. This eliminates
the need for periodic Join/Prune message transmission and processing.
The reliable transport mechanism can use either TCP or SCTP as the
transport protocol.
