Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and

23、 Systems (SES). The present document is part 3 of a multi-part deliverable covering the Broadband Satellite Multimedia (BSM) Regenerative Satellite Mesh - B (RSM-B); DVB-S/DVB-RCS family for regenerative satellites, as identified below: Part 1: “System overview“; Part 2: “Satellite Link Control laye

24、r“; Part 3: “Connection control protocol“; Part 4: “Specific Management Information Base“. ETSI ETSI TS 102 429-3 V1.1.1 (2006-10) 6 1 Scope The present document defines the Connection Control Protocol (C2P) used within SES BSM Regenerative Satellite Mesh B (RSM-B) to provide connections in a DVB-RC

25、S network using Type A terminals. The C2P is the protocol used for NCC and RCST communication (N interface) . The information elements used to build the C2P messages are identical to the ones defined in EN 301 790 1 and TR 101 790. The present document includes the definition of the C2P messages and

26、 protocol procedures required to support RSM-B system as a connection oriented network. The aim of the present document is a complement for the DVB-RCS and DVB-S standards defining the NCC and RCST interface to ensure RSM-B interworking with IP multimedia networks and services.
