6、rds 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. International organ

7、izations, 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 given i

8、n 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 least 75 %

9、 of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 17355 was prepared by the Consultative Committee for Space

10、Data Systems (CCSDS) (as CCSDS 727.0-B-3, June 2005) 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 third editi

11、on cancels and replaces the second edition (ISO 17355:2004), which has been technically revised. BS ISO 17355:2007blank1Space data and information transfer systems CCSDS file delivery protocol 1 Scope This International Standard defines a CCSDS file delivery protocol (CFDP) and associated service fo

12、r application in the space environment. It is intended for use over the current and envisaged packet delivery services used in the space environment, including CCSDS conventional packet telecommand; CCSDS conventional packet telemetry; CCSDS advanced orbiting systems (AOS) path service. It may also

13、operate over a wide variety of ground network services, including those specified by the CCSDS for cross-support purposes. The protocol operates in the space-to-ground, ground-to-space, and space-to-space directions of transfer. It may be initiated by the file sending or receiving entity. In the int

14、erests of interoperability, protocol elements are included for generalized forms of standard file manipulation operations based on assumptions of a common model for a filestore, or medium used to store files. It is recognized, however, that the precise nature and capabilities of filestore management

15、 systems are operating-system dependent and, for that reason, the protocol assumes a virtual filestore and associated services that an implementation must map to the capabilities of the actual filestore used. The scope and field of application are furthermore detailed in subclauses 1.2 and 1.3 of th

16、e enclosed CCSDS publication. 2 Requirements Requirements are the technical recommendations made in the following publication (reproduced on the following pages), which is adopted as an International Standard: CCSDS 727.0-B-3, June 2005, CCSDS file delivery protocol (CFDP).

24、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 are common to all participants, and to formulate sound technical solutions to these problems. I

25、nasmuch 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 issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommendatio

26、n 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 Recommended Standard. Establishing such a standard does not preclude other provisions which a member may

27、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 operational capability. - The anticipated duration of operational service. o Specific service arran

28、gements 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 issuance, this Recommended Standard will be reviewed by the CCSDS to determine whether it should: (1)

29、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 Recommended Standard is issued, existing CCSDS-related member standards and implementations are no

30、t 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 to direct planning for its new standards and implementations towards the later version of the R

31、ecommended Standard. BS ISO 17355:2007CCSDS RECOMMENDED STANDARD FOR CCSDS FILE DELIVERY PROTOCOL (CFDP) CCSDS 727.0-B-3 Page iii June 2005 FOREWORD Until relatively recently the typical storage medium for spacecraft has been the tape recorder, a complex device offering limited data storage and data

32、 access. The use of this type of storage has typically been limited to the recording and subsequent dump to the ground of telemetry data. Manipulation from the ground has required significant human intervention and used ad hoc, privately developed protocols. The introduction of solid state mass memo

33、ry providing gigabytes of storage with random access opens up a whole new ethos of spacecraft operation where much of the routine traffic to and from the spacecraft will be in the form of files. Furthermore, because of the random access nature of the onboard storage medium, it becomes possible to re

34、peat transmission of data lost on the link and thus guarantee delivery of critical information. To exploit the potential advantages of onboard mass memory, protocol support is required to provide a standard means to move data to and from the onboard storage medium in the form of files. While the onb

35、oard storage medium has rapidly evolved, the essential constraints of space missions remain: limited systems resources in terms of computational power and memory capacities; environmental restrictions including noisy, bandwidth limited, asymmetrical, and interrupted communications links, some with v

36、ery long propagation delay; varying user needs including a requirement for early access to transferred data regardless of its quality. In view of these constraints, it is clear that there is a need for a file delivery service capable of transferring files to and from mass memory located in the space

37、 segment. Such a capability must not only operate under the constraints associated with space data communication, but it must also be applicable to the diverse range of mission configurations ranging from single low earth orbiting spacecraft to complex networks of relays, orbiters, and landers. Thro

38、ugh the process of normal evolution, it is expected that expansion, deletion, or modification of this document may occur. This Recommendation is therefore subject to CCSDS document management and change control procedures which are defined in reference A1. Current versions of CCSDS documents are mai

The first bit in th

49、e field to be transmitted (i.e., the most left justified when drawing a figure) is defined to be Bit 0; the following bit is defined to be Bit 1 and so on up to Bit N1.
