Objectives
The aim of this project is to implement the next-generation gateway, optimized for broadband multi-media communications over satellites. It will draw on the full power of the DVB-RCS protocol, and will merge technical advances on transport layer optimization, Quality of Service (QoS) provisioning and dynamic bandwidth allocation. It will represent a significant advance in TCP/IP acceleration utilizing the Space Communications Protocol Specification – Transport Protocol (SCPS-TP) standard, targeted at dynamic bandwidth systems; providing both more effective network utilization and enhance the user experience to a level that makes full use of the broad bandwidth available.
Challenges
The key issues addressed in this project are to adapt XipLink SCPS-TP Gateways for optimum bandwidth use within the unique and challenging communications environment presented by DVB-RCS satellite networks.
Plan
Techniques to improve the performance will be designed, simulated by the Communications Research Centre (using a simulation previously correlated with the XipLink implementation), and finally implemented within XipLink Gateways and tested. Interested parties are encouraged to contact us if they would like to participate in testing.
Current Status
The project has been completed successfully in the first quarter 2004. As an integrated component of XipLink, the technology is currently being successfully deployed commercially worldwide, licensed into DVB-RCS terminals and sold as standalone XipLink Gateways.
