9、al 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. Internatio

BS ISO 18446:2016CCSDS RECOMMENDED PRACTICE: API FOR THE SLE FSP SERVICE CCSDS 916.3-M-2 Page ii September 2015 STATEMENT OF INTENT The Consultative Committee for Space Data Systems (CCSDS) is an organization officially established by the ma
17、nagement 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 results of Committee actions are termed Re
18、commendations 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 their space mission support infrastructure
19、 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 Practice is issued by, and represents the consens
20、us 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 issuance, this Recommended Practice will be revie
21、wed 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 newdirections; or (3) be retired or canceled.In those instances when a new version of a Recommended Practice is issued, existing CCSDS-
22、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 to direct planning for its new Practices and
23、 implementations towards the later version of the Recommended Practice.

24、 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 CCSDS. This Recommended Practice specifies se
25、rvice type-specific extensions of the Space Link Extension Application Program Interface for Transfer Services specified by CCSDS (reference 4). It allows implementing organizations within each Agency to proceed with the development of compatible, derived Standards for the ground systems that are wi
26、thin 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 some of the elements of this document may be the
27、 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 shall not be held responsible for identifying a
28、ny 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 procedures, which are defined in Organization and
29、 Processes for the Consultative Committee for Space Data Systems (CCSDS A02.1-Y-4).

43、d Practice Space Link ExtensionApplication Program Interface for Transfer ServicesCore Specification (reference 5) specifies a C+ API for CCSDS Space Link Extension Transfer Services. The API is intended for use by application programs implementing SLE transfer services. Reference 5 defines the arch
44、itecture of the API and the functionality that is independent of specific SLE service types. The purpose of this document is to specify extensions to the API needed for support of the Forward Space Packet Service defined in reference 3. 1.2 SCOPE This specification defines extensions to the SLE API
45、in terms of: a) the FSP-specific functionality provided by API components; b) the FSP-specific interfaces provided by API components; and c) the externally visible behavior associated with the FSP interfaces exported by the components. It does not specify: a) individual implementations or products;
46、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 Forward Space Packet service in addition to the specification in reference 5.

48、ion 2 identified by the version number 1 in the BIND operation, as specified by reference C8; b) Generation 3 identified by the version number 4 in the BIND operation, as specified in reference 3. NOTES 1 The use of the term Generation follows the definition in the API Core Specification (reference
49、4), where it is used to classify all SLE Transfer Services. 2 Support for Generation 1 is not valid in this book because the FSP initial issue was written as part of Generation 2 of the RAF, RCF and CLTU specific version 1 recommendations. Support for Generation 2 of the service is included for backward compatibility purposes for a limited time and may not be continued in future versions of this specification.
