The present document is part 1 of a multi-part deliverable covering the Broadband Satellite Multimedia (BSM) Regenerative Satellite Mesh - B (RSM-

19、B); DVB-S / DVB-RCS family for regenerative satellites, as identified below: Part 1: “System Overview“; Part 2: “Satellite Link Control layer“; Part 3: “Connection control protocol“; Part 4: “Specific Management Information Base“. ETSI ETSI TS 102 429-1 V1.1.1 (2006-10) 6 1 Scope The present documen

20、t is an introduction to SES BSM Regenerative Satellite Mesh - B (RSM-B) system architecture. It contains the description of the overall network and layered architecture of the BSM Regenerative Satellite Mesh - B (RSM-B). RSM-B network combines two standards, DVB-RCS for the uplink signal and DVB-S f

21、or the downlink signal. This document also describes the DVB-RCS and DVB-S profiles for the air interfaces so that Return Channel Satellite Terminals (RCSTs) have access to star services, meaning access to terrestrial networks, and mesh services, direct communication between RCSTs in only one hop. 2
