Question
A large IPTV service provider primarily uses multicast for delivering IPTV services to its customers. The service provider delivers digital television channels to home viewers by using a set-top box as a home appliance and controls this device through its video middleware. Each video channel uses a unique multicast group address. Recently, some channels have higher channel change times; to alleviate this problem, a number of solutions were discussed between the operations and engineering groups. Adding to the complexity of the issue is the fact that the business has been growing, and the service provider made acquisitions both in its home operating market and new geographic locations. These changes have made the management of source and group addresses a major concern. The engineering team thinks that using static joins for popular channels at the edge routers and moving away from Sparse Mode to SSM-based forwarding will improve performance issues. What are two valid concerns for the operations group? (Choose two.)
Options
- AIf SSM is used in the network, the operations team will need to use the rendezvous point for multicast
- BReplacing a shared multicast tree with SSM offers no security or convergence advantage.
- CUsing DNS-based SSM maps might not be possible.
- DA mix of static and dynamic joins will make troubleshooting difficult.
- EProvisioning and managing static joins can increase operational overhead.
