Executive summary The p

17、resent document summarizes the main functions of the ETSI BSM architecture, with special emphasis on the services offered by Satellite Independent Service Access Point (SI-SAP) interface to the higher protocol layers as well as the primitives defined to invoke those services. In more detail, the pre

18、sent document provides a guide to the use of the related ETSI BSM documentation, worked out since year 2001 and updated in year 2015, providing precise pointers to the ETSI technical specifications (TSes) and reports (TRs), where the ETSI BSM architecture functions and SI-SAP interface services are

19、defined and specified. The aim of the present document is illustrate the main functions of the ETSI BSM architecture and the services offered by the SI-SAP interface. Introduction The present document focuses on the ETSI BSM architecture which defines the main actors involved in satellite communicat

20、ions, including the satellite network itself, external subnetworks, and the related interfaces. In particular, the ETSI BSM architecture defines a layered architecture separating the satellite dependent (SD, physical and datalink layers according to ISO/OSI terminology) from the satellite independen

21、t (SI, network layer) by means of the Satellite Independent Service Access Point (SI-SAP) interface, which provides an hardware abstraction layer easing the implementation of cross-layer mechanisms and interoperability of multi-vendor devices. The SI-SAP interface can be actually implemented as logi

22、cal or physical interface. In the former configuration, the SI-SAP interface extends and adapts the functions already provided by the interface existing between L1 and L2 of the ISO/OSI protocol stack, hence possibly enabling new services. On the other hand, the latter configuration corresponds to t

23、he case where the SI-SAP interface is actually implemented in two physically separated elements (e.g. a user terminal and a satellite modem), whereby the defined SI-SAP services can be run by means of a dedicated message exchange protocol. ETSI ETSI TR 103 444 V1.1.1 (2016-12) 5 The aforementioned c

24、apabilities offered by the SI-SAP interface are defined in terms of specific services that can be requested by the SI layer to the SD layer, respectively implementing SD and SI adaptation functions (provided namely by the SDAF and SIAF modules) for this purpose. In particular, the SI-SAP services cu

25、rrently defined deal with control and user plane functionalities, such as data transfer, address resolution, resource reservation, multicast management, logon/logoff, and configuration of the satellite independent (SI) layer. The present document addresses the functions offered by the ETSI BSM archi

26、tecture and the services implemented by the SI-SAP interface, illustrating the main characteristics and pointing to the related ETSI BSM literature, so as to offer a standalone guidance document for satellite system designers and implementers. ETSI ETSI TR 103 444 V1.1.1 (2016-12) 6 1 Scope The pres

27、ent 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 descriptio

28、n 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

29、 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 po

30、inters 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 transf

31、er. 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. 2 References 2.1 Normative references Normative references are not applicable in the present document.
