Source Specific Multicast (SSM)
Multicast supports both many-to-many and one-to-many models, which are also known
as Any Source Multicast (ASM). In this model, receivers may join and leave multicast
groups with (*, G) state that indicates any source and group G. Since there is no means to
specify the source
’s information, source discovery such as the RP mechanism in PIM-SM
is needed, which is the key feature of ASM. Each group address is identified as 224.0.0.0
