9、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. International organizations, governmental
10、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. The procedures used to develop this document and those intended for its further maintenance are
11、 described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives Attention is drawn t

20、ganization officially established by the management of its 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
21、 results of Committee actions are termed Recommendations and are not in themselves considered binding on any Agency. CCSDS Recommendations take two forms: Recommended Standards that are prescriptive and are the formal vehicles by which CCSDS Agencies create the standards that specify how elements of
22、 their space mission support infrastructure shall operate and interoperate with others; and Recommended Practices that are more descriptive in nature and are intended to provide general guidance about how to approach a particular problem associated with space mission support. This Recommended Practi
23、ce is issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommended Practice is entirely voluntary and does not imply a commitment by any Agency or organization to implement its recommendations in a prescriptive sense. No later than five years from its date of issuan
24、ce, this Recommended Practice 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 directions; or (3) be retired or canceled. In those instances when a new version of a Re
25、commended Practice is issued, existing CCSDS-related member Practices and implementations are not negated or deemed to be non-CCSDS compatible. It is the responsibility of each member to determine when such Practices or implementations are to be modified. Each member is, however, strongly encouraged
26、 to direct planning for its new Practices and implementations towards the later version of the Recommended Practice.

27、s a technical Recommended Practice for use in developing ground systems for space missions and has been prepared by the Consultative Committee for Space Data Systems (CCSDS). The Application Program Interface described herein is intended for missions that are cross-supported between Agencies of the
28、CCSDS. This Recommended Practice specifies service type-specific extensions of the Space Link Extension Application Program Interface for Transfer Services specified by CCSDS (reference 3). It allows implementing organizations within each Agency to proceed with the development of compatible, derived
29、 Standards for the ground systems that are within their cognizance. Derived Agency Standards may implement only a subset of the optional features allowed by the Recommended Practice and may incorporate features not addressed by the Recommended Practice. Attention is drawn to the possibility that som
30、e of the elements of this document may be the subject of patent rights. CCSDS has processes for identifying patent issues and for securing from the patent holder agreement that all licensing policies are reasonable and non-discriminatory. However, CCSDS does not have a patent law staff, and CCSDS sh
31、all not be held responsible for identifying any or all such patent rights. Through the process of normal evolution, it is expected that expansion, deletion, or modification of this document may occur. This Recommended Standard is therefore subject to CCSDS document management and change control proc
32、edures, which are defined in Organization and Processes for the Consultative Committee for Space Data Systems (CCSDS A02.1-Y-4).

44、BS ISO 18442:2016CCSDS RECOMMENDED PRACTICE: API FOR THE SLE RAF SERVICE CCSDS 915.1-M-2 Page 1-1 September 2015 1 INTRODUCTION 1.1 PURPOSE The Recommended Practice Space Link ExtensionApplication Program Interface for Transfer ServicesCore Specification (reference 3) specifies a C+ API for CCSDS Sp
45、ace Link Extension Transfer Services. The API is intended for use by application programs implementing SLE transfer services. Reference 3 defines the architecture of the API and the functionality on a generic level, which is independent of specific SLE services and communication technologies. It is
46、thus necessary to add service type-specific specifications in supplemental Recommended Practices. The purpose of this document is to specify extensions to the API needed for support of the Return All Frames (RAF) service defined in reference 2. 1.2 SCOPE This Recommended Practice defines extensions
47、to the SLE API in terms of: a) the RAF-specific functionality provided by API components; b) the RAF-specific interfaces provided by API components; and c) the externally visible behavior associated with the RAF interfaces exported by the components. It does not specify a) individual implementations
48、 or products; b) the internal design of the components; and c) the technology used for communications. This Recommended Practice defines only interfaces and behavior that must be provided by implementations supporting the Return All Frames service in addition to the specification in reference 3. ISO
