scope:

The present document provides a guide to ETSI BSM architecture and SI-SAP interface for satellite system designers and implementers, in terms of pointers to the relevant ETSI BSM literature. Firstly, the document addresses the functions that are offered by the ETSI BSM architecture, providing the description of the main features and pointing to the specific TSs and TRs that detail these functions. In more detail, the following functions are illustrated:

• Data transfer.

• QoS management.

• Address resolution.

• Multicast management.

• Security.

• Network integration.

• Performance management

Secondly, the document addresses the services that are offered by the SI-SAP interface and are run between the satellite independent (SI) and satellite dependent (SD) layers. Similarly to the description of the aforementioned ETSI BSM architecture functions, illustration of the main features is provided along with the pointers to the relevant ETSI BSM documents where the SI-SAP services are defined, specified, and analysed. The considered SI-SAP interface services are:

• Logon/logoff.

• Satellite independent layer configuration.

• Address resolution.

• Resource reservation.

• Multicast group receive and transmit.

• Data transfer.

The aim of the present document is to provide a standalone guide to the ETSI BSM standardization track, which is based on several technical specifications and reports.
