The work of preparing International Standards is normally
9、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 and non-governmental, in liaison with ISO, also take part in the wo

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the dif

16、ERNET PROTOCOL FOR TRANSFER SERVICES CCSDS 913.1-B-2 Page ii September 2015 STATEMENT OF INTENT The Consultative Committee for Space Data Systems (CCSDS) is an organization officially established by the management of its members. The Committee meets periodically to address data systems problems that
17、 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 Standards and are not considered binding on any Agency. This Recommended Standard is
18、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 CCSDS-related standard, this standard will be in accord with the relevant Recommend
19、ed 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 following information: - The standard itself. - The anticipated date of initial ope
20、rational 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 substitute for a memorandum of agreement. No later than five years from its date of issuan
21、ce, 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 directions; or (3) be retired or canceled. In those instances when a new version of a Re
22、commended 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 or implementations are to be modified. Each member is, however, strongly encouraged
23、 to direct planning for its new standards and implementations towards the later version of the Recommended Standard.

24、s drawn to the possibility that some 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 ha
25、ve a patent law staff, and CCSDS shall 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
26、 management and change control procedures, which are defined in Organization and Processes for the Consultative Committee for Space Data Systems (CCSDS A02.1-Y-4).

44、ansfer Services that enable missions to send forward space link data units to a spacecraft and to receive return space link data units from a spacecraft. A subset of these services is specified by the SLE Transfer Service Recommended Standards (references 2, 3, 4, 5, and 6). The SLE Transfer Service
45、 Recommended Standards specify a) the operations necessary to provide the transfer service; b) the parameter data associated with each operation; c) the behaviors that result from the invocation of each operation; and d) the relationship between, and the valid sequence of, the operations and resulti
46、ng behaviors. However, they deliberately do not specify the methods or technologies required for communications. The purpose of this Recommended Standard is to define a protocol for transfer of SLE Protocol Data Units (PDUs) defined in the SLE Transfer Service Recommended Standards using the Interne
47、t protocols TCP (Transmission Control Protocol, reference 7) and IP (Internet Protocol, reference 8) for data transfer and the Abstract Syntax Notation One (ASN.1, references 9 and 10) for data encoding. This protocol is referred to as the Internet SLE Protocol One (ISP1). 1.2 SCOPE This Recommended
48、 Standard defines a protocol for transfer of SLE PDUs between an SLE user and an SLE provider system in terms of: a) the procedures used to establish and release associations; b) the messages exchanged on an established association; c) the procedures used to monitor the status of data communication
49、connections; and d) the methods used to ensure that data are converted between different formats and representations on different platforms. It does not specify: a) individual designs, implementations, or products; b) the configuration of the data communications infrastructure, including configuration of the TCP and IP protocols; ISO 18440:2016 (E) ISO 2016 All rights reservedBS ISO 18440:2016SPACE LINK EXTENSIONINTERNET PROTOCOL FOR TRANSFER
