ETSI - TS 102 460

Satellite Earth Stations and Systems (SES); Broadband Satellite Multimedia (BSM); Address Management at the SI-SAP

scope:

The present document concerns the address management functions that are required to support interworking of a BSM network with an IP network, including use as part of the general Internet, in particular the address management functions related to the BSM SI-SAP.

The SI-SAP is described in the BSM functional architecture [1] and defined in the SI-SAP specification [3]. A key element in the present document is the BSM_Identifier (BSM_ID) which is the SI-SAP address that identifies a BSM subnetwork point of attachment (SNPA). A BSM network uses the BSM_ID when sending and receiving data via the SI-SAP: the BSM_ID is an abstraction of the lower layer address that would otherwise be used. The present document describes the relationships between IP Addresses and BSM_IDs and also describes how to create, manage, and query the BSM_IDs for the purpose of sending and receiving user data (in particular IP packets) via the SI-SAP.

NOTE 1: In some systems, requesting to pass traffic across the network also causes reservation of bandwidth. This is to be considered out of scope of the present recommendation, but assumptions that a notification (e.g., bandwidth allocation) will be sent by a QoS Manager will be made.

The present document divides into two parts:

• address management scenarios and architectures;

• unicast address resolution at the SI-SAP.

Lower layer address management (i.e. management of addresses below the SI-SAP) is beyond the scope of the present document.

NOTE 2: Examples of lower layer addresses that are out-of-scope include Data Link layer addresses, MAC layer addresses and Physical layer addresses.

The present document elaborates the details of the address management functions, notably the address resolution function, as defined in the SI-SAP specification ETSI TS 102 357 [3]. It also builds on several other reports:

• ETSI TR 101 984 [i.1];

• ETSI TR 101 985 [i.2];

• ETSI TR 102 155 [i.7].
