Interactive broadband satellite networks targeting consumer and business applications have to meet many stringent requirements and constraint to be competitive with respect to terrestrial broadband networks:
This project studies the efficient networking and MAC techniques that are able to satisfy these requirements in interactive broadband satellite systems (DVB-RCS NG, VSAT, Mesh).
The project takes the DVB-RCS NG commercial requirements as initial point and then, reviews the current status of the Higher Layers for Satellite (HLS) specifications for Interactive Broadband Satellite systems. The main target is to obtain specific recommendations, and perform several efficiency evaluation tasks that will derive a new set of recommendations to complete the standardization.
The first objective of the project is the development of recommendations for the following aspects of DVB-RCS NG:
The second objective is to assist the Agency in the DVB-RCS NG standardization process regarding the above mentioned HLS and MAC aspects: firstly, in the form of contributions to the TM-RCS group, and secondly with white papers and contributions to other standardization groups and General Stakeholders in Broadband Interactive satellite systems. Once the RCS2 HLS normative specification is closed, the focus will move to recommendations to be included in the guidelines document(s) of RCS2.
The recommendations will be supported by performance and functional evaluation, using network simulation tools (e.g., OPNET, OMNET, NS2) and protocol and systems simulation tools (Rational ROSE) to help identify the optimal solution.
Efficient networking and MAC techniques in Next Generation interactive broadband satellite networks addressing:
At no time in history have telecommunications and networking standards and guidelines been more important. Such standards and rules are being developed by a range of IP networking standardisation bodies in order to allow high quality communications and rapid interconnections of different media. The correct definition of the Higher Layer Satellite for interactive satellite broadband satellite networks (not only DVB-RCS2) will be crucial to ensure satellite systems become an integral part of the all-IP network.
The work to be performed in this project will produce a series of white papers describing provision of efficient networking and MAC techniques that satisfy key commercial requirements for the satellite interactive network such as the interoperability among different manufacturers, seamless integration with terrestrial networks, achieving a user experience close to those terrestrial access networks, and costs reduction to make satellite services affordable for consumers. These will be appropriate to a range of satellite systems and will be made available to the wider community. It will apply these results to derive specific recommendations to assist the Agency support for the to the TM-RCS group for the completion of the normative documents.

The work will be performed during 12 months and is divided into four separate Work Packages (WPs):
The output of the WP1000 and WP2000 will propose enhancements in key areas with target objectives and priorities for the work in DVB-RCS NG HLS.
