Executive summary Satellites are ideally suited to multicast, due to their large coverage areas and inherent broadcasting abilities.
Multicast support requires next-generation satellite systems.
The building blocks will be simulated in order to examine their performance. System overview and specification Perform an overview of existing and forthcoming systems and identify typical reference scenarios to support multicast services. Perform the necessary research work to specify the protocols and building blocks that can bring solutions to the problems raised. CCSR will perform an overview of security challenges and examine a number of issues related to satellite multicast security. This work will be completed by the specification of a live demonstration over a real high-frequency payload.
