Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). Introdu
22、ction This Technical Report is the output from Task 6 of SES BSM STF 283, “Transition to IPv6“. The terms of reference for task 6 state that this Technical report will address the following issues: A technical review of the transition to IPv6 Provide an overview of the satellite specific issues rela
23、ting to the introduction of IPv6 networks Produce recommendations for further work to support the introduction of IPv6 in satellite communications, and in particular into the BSM architectures and standards The overall structure of this document follows the broad outlines of previous BSM Technical R
24、eports, with Chapters on Services, Functional Requirements and Functional Architecture, followed by a Chapter on Recommendations for Future Work. Running through these topics will be reference to the various underlying Satellite-specific network aspects that have been defined beneath the SI-SAP laye
25、r in previous BSM work. In particular, the impact of transition to IPv6 may be different for star architecture, mesh architecture, transparent and regenerative satellite payloads. ETSI ETSI TR 102 467 V1.1.1 (2007-01) 6 1 Scope The present document examins the transition to IPv6 is in the context of
26、 the forces motivating this transition and both the “end-game“ services and architecture (when IPv6 is ubiquitous) and the transitional phase where interworking between IPv4 equipment and IPv6 equipment will become the norm. The purpose of this document is to survey the major technical and functiona
27、l consequences of these developments on the BSM. It will consider the particular effects on the BSM Functional and Services Architecture as already developed in earlier Technical Reports and Technical Standards. By reference to these documents, especially references 24 to 30 and 36. This Technical R
28、eport identifies areas of the BSM architecture where further Technical Specifications and Reports need to be developed to handle the issues arising from the transition to IPv6 (see clause 12). Aspects of address resolution, configuration management, performance and interworking will form the main fo
29、cus of the work. Consideration will also be given to Quality of Service impacts, multicasting and security. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
