15、2, September 2015) 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. This second edition cancels and replaces the first

16、 edition (ISO 18441:2013), which has been technically revised. BS ISO 18441:2016CCSDS 914.0-M-2 Page ii September 2015 API FOR SLE TRANSFER SERVICESCORE SPECIFICATION STATEMENT OF INTENT The Consultative Committee for Space Data Systems (CCSDS) is an organization officially established by the manage

17、ment 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 Recomm

18、endations 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 sha

19、ll 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 consensus o

20、f, 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 reviewed

21、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-rela

22、ted 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 imp

23、lementations towards the later version of the Recommended Practice.

24、 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 shall not be held responsib

25、le 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 procedures, which are defined

47、o define a C+ Application Program Interface (API) for CCSDS Space Link Extension (SLE) Transfer Services, which is independent of any specific technology used for communications between an SLE service user and an SLE service provider. This API is intended for use by application programs implementing

48、 SLE services. It can be configured to support SLE service user applications or SLE service provider applications. This API is also intended to simplify the implementation of gateways that are required to achieve interoperability between SLE service provider and SLE service user applications using d

49、ifferent communications technologies. Using this Application Program Interface Recommended Practice, API implementations (software packages) able to run on specific platforms can be developed. Once developed, such a package can be supplied to new users of SLE services for integration with their user or production facilities, thus minimizing their investment to buy into SLE support. 1.2 SCOPE 1.2.1 ITEMS COVERED BY THIS RECOMMENDED PRACTICE This Recommended Practice defines the Applicatio
