The scope of the present document is the review of study topics with respect to the provision of IP-based services via Broadband Satellite Multimedia (BSM) networks. The present document builds on the following two earlier reports:
- TR 101 374-1 [i], "Survey on Standardization Objectives for Broadband Satellite Multimedia".
- TR 101 374-2 , "Standardization Objectives for Broadband Satellite Multimedia: The Standardization Scenario".
The present document also builds on the general BSM Services and Architectures defined in:
- TR 101 984 , "Services and Architectures"
The present document discusses the standardization approach, relevant issues and provides a reference framework for further work that should be undertaken within ETSI with regard to the use of Broadcast Satellite Multimedia (BSM) networks to transport IP-structured traffic. The report is focussed on the following aspects off IP over satellite:
- BSM systems based on GeoSynchronous Orbit (GSO) satellites;
- integration of BSM services with IP-based services;
- integration of BSM satellite networks with terrestrial networks;
- integration of BSM broadcast and multicast services with IP-based services, including IP multicast services.
The structure defined in the present document is intended to provide a framework for a series of detailed studies on specific issues which are expected to identify existing standards and to identify areas where new standards are required, in order to achieve these objectives. The objectives of BSM standardization are:
- to enable users to access a wide range of telecommunications services, with particular emphasis on multi-media services and high data rates;
- to provide an efficient means of using network resources (particularly radio spectrum);
- to enable the benefits of satellite technology to be made available to a wide range of users;
- to facilitate the provision of a high quality of service for transporting IP traffic over BSM networks;
- to facilitate the provision of low cost terminals.
