"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 [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 [3]@ ""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."
