11、 this International Standard) by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 13, Space data and information transfer systems. DEDICATION This book is dedicated to Adrian Hooke, whose end-to-end sensibilities and tireless advocacy for standardization of space data syst

12、ems directly contributed to the formation of the Consultative Committee for Space Data Systems in 1982. His unique combination of technical skill, management abilities, and vision served CCSDS well for over 30 years. During that time CCSDS solidified the standardization of Physical and Data Link Lay

13、er protocols, and developed standards and technologies that had important and wide-ranging impacts in both the space and terrestrial communications industries. In the late 1990s, Adrian envisioned a new era for space communications leveraging a confluence of terrestrial internetworking and space-bas

14、ed data transport technologies. This led to the development of a concept that has come to be known as the Solar System Internetwork (SSI), of which the Licklider Transmission Protocol described here is a part. Adrian will be missed, by CCSDS for the scope of his technical contributions and his leade

15、rship, and by his colleagues and friends for the greatness of his spirit and his wit. But his legacy to the space community remains. CCSDS will continue to provide useful and innovative solutions to space communication challenges so that Adrians vision of an interoperable, standards-based communicat

16、ion system that reduces mission development time, cost, and risk will eventually be realized.

20、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 are common to all participants, and to formulate sound technical solutions to these p

21、roblems. 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 issued by, and represents the consensus of, the CCSDS members. Endorsement of this Rec

22、ommendation 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 m

23、ember 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 operational capability. - The anticipated duration of operational service. o Specific ser

24、vice 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 issuance, this Recommended Standard will be reviewed by the CCSDS to determine whether it sh

25、ould: (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 Recommended Standard is issued, existing CCSDS-related member standards and implementati

26、ons 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 to direct planning for its new standards and implementations towards the later versio

27、n of the Recommended Standard.

28、 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 any or all such patent rig

29、hts. 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 Processes for the Consul

30、tative Committee for Space Data Systems (CCSDS A02.1-Y-4).

For space data links, LTP will typically be deployed over a CCSDS data link that supports CCSDS Encapsulation Packets so that one LTP segment can be encapsulated in a single Encapsulation Packet.

38、 LTP may also operate over a wide variety of ground-network services including those specified by the CCSDS for cross-support purposes. 1.3 ORGANIZATION OF THE DOCUMENT This Recommended Standard is organized as follows: a) Section 2 contains a descriptive overview of LTP operation as well as a brief

39、 history of the protocols heritage. Users not already familiar with LTP may want to start with this section. b) Section 3 contains a profile of RFC 5326 (reference 3) for use by CCSDS. c) Section 4 contains the abstract service specification for LTP. d) Section 5 specifies the services that LTP requ

40、ires from the underlying system. e) Section 6 contains conformance requirements for the CCSDS profile of LTP. f) Section 7 defines a client operations service that allows multiple layer-(N+1) SDUs to be aggregated into a single LTP block in order to improve efficiency. g) Annex A contains the Protocol Implementation Conformance Statement (PICS) proforma. h) Annex B specifies how to layer LTP over the CCSDS Space Packet Service or the CCSDS Encapsulation Service. i) Annex C contains the Management Information Base (MIB) for the protocol.
