MUlticast Streaming Technology


1. To provide an overview of the available multicast solutions suitable for Grid technology and their relative merits (reliability, scalability, flexibility, network requirements and ease of implementation). Numerous multicast transport protocols currently exist. A number of these protocols are commercial; others are available as Open Source. 2. To evaluate the performance for various transport scenarios relevant to RealityGrid of a number of these protocols. This evaluation will be in terms of the improvement in throughput and bandwidth saving that they provide in comparison to TCP/IP unicast transport and their impact on network traffic. Our focus will be primarily on Open Source and end-to-end protocols, which have the potential to be integrated in the Grid infrastructure (either as an extension to the functionality of Globus toolkit or in parallel to Globus) and require little or no change within internal network equipments, such as routers or switches. 3. To prove the claimed benefits of using Digital Fountain (DF) as an alternative or replacement for GridFTP transfers. This will involve transport level experimental runs over the RealityGrid network testbed using multicast and unicast streams on UDP level according to DF solution implementations. There will be comparative network analysis between the transport utilising TCP and GridFTP on one side and DFs FEC (Forward Error Correcting) coding technology running reliably over UDP level. 4. To investigate the use of reliable UDP on Access Grid sessions (e.g. between Manchester, London, Oxford, Edinburgh and Cambridge). This will enable assessment of its potential for providing highly robust networking to increase Access Grid performance and improve users experience of this technology.
