8、l standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internation

9、al organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules

10、 given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at le

ISO shall not be held responsible for identifying any or all such patent rights. ISO 20206 was prepared by the Consultative Committee fo

12、r Space Data Systems (CCSDS) (as CCSDS 702.1-B-1, September 2012) and was adopted (without modifications except those stated in clause 2 of this International Standard) by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 13, Space data and information transfer systems.

18、ts members. The Committee meets periodically to address data systems problems that are common to all participants, and to formulate sound technical solutions to these problems. Inasmuch as participation in the CCSDS is completely voluntary, the results of Committee actions are termed Recommended Sta

19、ndards and are not considered binding on any Agency. This Recommended Standard is issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommendation is entirely voluntary. Endorsement, however, indicates the following understandings: o Whenever a member establishes a C

20、CSDS-related standard, this standard will be in accord with the relevant Recommended Standard. Establishing such a standard does not preclude other provisions which a member may develop. o Whenever a member establishes a CCSDS-related standard, that member will provide other CCSDS members with the f

21、ollowing information: - The standard itself. - The anticipated date of initial operational capability. - The anticipated duration of operational service. o Specific service arrangements shall be made via memoranda of agreement. Neither this Recommended Standard nor any ensuing standard is a substitu

22、te for a memorandum of agreement. No later than three years from its date of issuance, this Recommended Standard will be reviewed by the CCSDS to determine whether it should: (1) remain in effect without change; (2) be changed to reflect the impact of new technologies, new requirements, or new direc

23、tions; or (3) be retired or canceled. In those instances when a new version of a Recommended Standard is issued, existing CCSDS-related member standards and implementations are not negated or deemed to be non-CCSDS compatible. It is the responsibility of each member to determine when such standards

24、or implementations are to be modified. Each member is, however, strongly encouraged to direct planning for its new standards and implementations towards the later version of the Recommended Standard.

These terms are to be understood in a generic sense, i.e., in the sense that the terms are generally applicable to any of a variety of technologies that provide for the exchange of information between real systems. T

44、he terms are: a) Data Link Layer; b) protocol data unit; c) real system; d) service; e) Service Access Point (SAP); f) SAP address; g) Service Data Unit (SDU). 1.3.1.2 Definitions from OSI Service Definition Conventions This document makes use of a number of terms defined in reference 2.

IP PDU: Internet Protocol Protocol Data Unit; includes all IP data types e.g., IPV4, IPV6, compressed header IP PDUs. Physical Channel

48、: a stream of bits transferred over a space link in a single direction. space link: a communications link between a spacecraft and its associated ground system or between two spacecraft. A space link consists of one or more Physical Channels in one or both directions. 1.4 CONVENTIONS 1.4.1 NOMENCLAT

49、URE The following conventions apply for the normative specifications in this Recommended Standard: a) the words shall and must imply a binding and verifiable specification; b) the word should implies an optional, but desirable, specification; c) the word may implies an optional specification; d) the words is, are, and will imply statements of fact. NOTE These conventions do not imply constraints on diction in text that is clearly informative in nature. 1.4.2
