There is a growing awareness of the potential for IP-based multicast services, initial applications include video streaming, with data-oriented services expected to follow. Satellite systems are ideally suited to deliver such services at a national/continental level. This project proposes research and analysis to address key challenges in the use of reliable IP multicast in future satellite networks.Reliable multicast is sometimes regarded as something of an 'oxymoron': When people talk about 'reliable multicast', they usually mean a single protocol at a single layer of the protocol stack. Building on the complementary expertise of the two collaborating research teams, this project departs from this strict layered-design methodology: It proposes integrating protocol mechanisms for security, link reliability and transport reliability to build a flexible, but efficient, reliable multicast protocol. Research will design, analyse, and optimise a novel adaptive Packet FEC mechanism that employs cross-layer methods to provide a significant (at least order of magnitude) improvement in performance. The security research will augment the transfer protocol by investigating and specifying new techniques employing hierarchical keys distributed using integrated reliability mechanisms to enable encryption, authentication, confirmation of delivery and measures to mitigate the impact of Denial of Service attacks.The overall goal will be to provide strong security together with high reliability, while offering a significant reduction in the cost associated with satellite transmission.
