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

Referenced documents which are not found to be publicly available in the expected location might be found at http:/docbox.etsi.org/Reference. F
30、or online referenced documents, information sufficient to identify and locate the source shall be provided. Preferably, the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the reference should, as far as possible, remain valid for the expected
31、 life of the document. The reference shall include the method of access to the referenced document and the full network address, with the same punctuation and use of upper case and lower case letters.
