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

28、plane management functions ETSI ETSI TS 102 429-1 V1.1.1 (2006-10) 7 Management Station (MS): controls and manages the RSM-B network NOTE: It is composed of three elements: - the Network Control Center (NCC); - the Network Management Center (NMC); - the satellite terminal of the MS (NCC_RCST), which
29、 supports the modulation and demodulation functions to access to the satellite. multicast: communication capability which denotes unidirectional distribution from a single source access point to a number of specified destination access points Network Control Center (NCC): RSM-B network element which
30、 controls the Interactive Network, serves users satellite rquests and manages the OBP configuration Network Management Center (NMC): RSM-B network element composed in charge of element management functions and for the network and service provisioning and management On Board Processor (OBP): satellit
31、e payload digital processor on-board the satellite that allows MPEG packets switching from up-link to down-link beams in a flexible way Return Channel Satellite Terminal (RCST): RSM-B network element installed in the user premises NOTE: It is a low cost and high-performance satellite terminal that p
32、rovides interfaces with final users. It allows its users access to users of others RCSTs or to external users of terrestrial networks through the RSGW, or to services delivered by the Service Provider attached to the RSGW GateWay Return Channel Satellite Terminal (GW_RCST): RSM-B network element ins
33、talled inside an RSGW NOTE: It corresponds to an RCST with enhanced properties in routing, IP multicast, connection control and management. Regenerative Satellite GateWay (RSGW): RSM-B network element that interfaces the RSM-B network with external users of terrestrial networks such as PSTN or ISDN
34、and with external Service Providers NOTE: A Gateway and one or several GW_RCST (Gateway Return Channel Satellite Terminal) compose the RSGW. A Gateway includes all the network elements that will assure the interface with terrestrial networks (e.g. IP router, Voice gateway, Video gateway, Gatekeeper,
35、 etc.). Quality of Service (QoS): measure of the parameters of a network that influence perceived quality of communications, including the delay, jitter, bandwidth, and packet loss that packets sent by the application experience when being transferred by the network user plane: plane which has a lay

The compatibility with these two standards is combined together with multispot capabilities and full cross-connectivity between the different Up-L
47、ink and Down-Link in the system. Figure 4.1 illustrates the previous concept. Satellite Satellite Satellite DVB-S transparent DVB-RCS transparent DVB-RCS DVB-S DVB-RCS / DVB-S Cross Connected RSM-B Figure 4.1: RSM-B system concept The RSM-B network is configured to fit both Star and Mesh topologies.
48、 The RSM-B network is based on DVB-RCS specification for the return channel (uplink) and DVB-S specification for the forward channel (downlink) communications. The RSM-B network provides broadband data services and access to terrestrial networks, mainly IP network and PSTN through gateways, star com
49、munications. RSM-B system may also be seen as a broadband multimedia platform oriented to mesh communications based in only one hop, very especially for those scenarios where broadband services and real-time communications are desired in a single and unique offer.
