Abstract-- Source Specific Multicast (SSM) provides native
support for single sender multicast applications. Current propos-
als for supporting multiple sender applications on top of SSM
includes using multiple SSM channels or using an application
layer relay mechanism on top of SSM. These approaches have
potential scalability or single point of failure problems, respec-
tively. In this paper, we propose network layer extensions to
SSM. Our extensions provide a convenient mechanism for SSM
group owners to include additional senders in their multicast
applications. We present our SSM extensions model and provide
a detailed discussion on the protocol operation under various sce-
narios. We also examine the protocol performance by comparing
