Source Specific Multicast (SSM) with IPv6

Source-Specific Multicast (SSM) is a more recent form of IP Multicast compared to the traditional Any Source Multicast (ASM) model. In making a fundamental assumption that there is only a single source in a specific Multicast group, simplifications can be made that lead to a new form of multicast that should be easier to deploy than ASM. The 6NET and Euro6IX projects have been at the forefront of SSM testing and deployment. In this paper we describe the results of work undertaken in these projects.
