Foreword This Technical Specification (TS) has been produc
44、ed by ETSI Technical Committee Satellite Earth Stations and Systems (SES). Introduction The present document is the first published version of a converged C2P specification for DVB-RCS systems, bringing together requirements for a range of different system scenarios. The present document is based on
45、 existing C2P implementation but with several important extensions and changes. Readers of the present document are therefore advised that the present document may be subject to changes in order to incorporate any possible corrections that may result from the testing and verification of the first im
46、plementations of the present document. ETSI ETSI TS 102 602 V1.1.1 (2009-01) 8 1 Scope The present BSM document defines and specifies a Connection Control Protocol (C2P) for DVB-RCS satellite networks, relying on specific DVB-RCS layer 2 signalling (DULM on the return link, unicast TIM on the forwar
47、d link). C2P is part of the control plane layer 2 functionality and is generally used for the dynamic establishment and management of connections between the ground elements of DVB-RCS networks (RCSTs, Gateways, NCC), regardless of their architectures and topologies (single-beam/multiple-beam archit
48、ectures, transparent/regenerative satellite payloads, star/mesh topologies). In this context C2P can be seen as a complement to the functionality of the interfaces already defined in the DVB-RCS and DVB-S/S2 standards 1 and i.1. The present document is organized as follows: Clause 4 contains the des
49、cription of the network reference scenarios (clause 4.2), of the C2P core elements (clause 4.3), of the connection types (clause 4.4) and of various data structures for dynamic connectivity support (clause 4.6). Clause 5 describes the state machines, including the timer and counter definitions and examples of state machines diagrams. Clause 6 describes the normal procedures and a few examples of exception procedures. Clause 7 describes the C2P Information Elements (IEs). Clause 8 defines the C2P messages. Annex A includes the description of C2P State Mac
