ETSI ETSI TR 102 603 V1.1.1 (2009-01) 61 Scope The present BSM document provides background information for the specif

23、ication of a Connection Control Protocol (C2P) for DVB-RCS networks i.11, relying on specific DVB-RCS signalling. C2P (and any other connection control protocol) is part of the control plane functionality and is generally used to establish connections with adequate resources in order to satisfy the

24、service requirements of various multimedia applications. In this context, it can be seen as one component of the QoS end-to-end architecture, e.g. as defined in i.3. Recommendations for QoS specifications for DVB-RCS networks have been proposed by the SatLabs Group i.4; they will be considered in th

25、e definition of C2P. Moreover, SatLabs Group has also provided recommendations for the Harmonized Management and Control Plane Specifications in DVB-RCS networks i.7; some of the specified data structures (with enhancements) will be used in the definition of C2P specification i.11. To facilitate the

26、 definition of C2P, the present document provides and overview of the following aspects: Reference scenarios for DVB-RCS networks. C2P core elements and their inter-relationships, captured in various C2P models. Internetworking issues relevant to C2P, including the QoS models adopted for C2P and var

27、ious terminal data structures (tables) for dynamic connectivity support. The intension is to identify those elements common to all network reference scenarios, in order to define a basic framework for the specification of a connection protocol applicable to all scenarios. 2 References References are

28、 either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is acce
