Enhanced IP-based satellite architecture compatible with many satellite platforms

In this document we describe the architecture of BRAHMS (Broadband Access for High speed Multimedia via Satellite), project sponsored by EU in the framework of IST research programme. BRAHMS aims at specifying an IP-based architecture for broadband satellite access independently of the particular GEO or LEO satellite technology adopted in the satellite link. Broadband Multimedia Satellite System (BMSS) is intended as a generic solution for provision of multimedia services via satellite access networks within a future worldwide IP-based terrestrial public network. This scenario is defined to promote integration and harmonization of many access networks services and functions (e.g. QoS, multicast, roaming, security) whilst allowing flexibility for optimized or proprietary air interfaces (i.e. frequency, access type, orbit, space segment architecture, etc.).
