| Summary: | Source Specific Multicast (SSM) has been
introduced to overcome the issues in Any Source
Multicast (ASM) such as security, deployment
complexity and address allocation. However, the
scalability issue of SSM still poses a problem. To solve
this state scalability problem, a scheme called
aggregated multicast is proposed. The key idea is that
multiple groups are forced to share a single delivery
tree. In this paper, the basic idea of SSM and ASSM is
give and a comparison between both is done. Based on
what we have done, we conclude that aggregated
multicast is an effective way to solve the scalability
issue of SSM. However, it may suffer from routers
under utilization problem. To achieve higher routers
utilization, this paper proposes a new approach. The
new approach was also discussed. |
