ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrot

15、nous Message Service (AMS) for mission data system communications. The service and its protocols implement an architectural concept under which the modules of mission systemsdistinct sequential flows of application control logic, whether called processes, tasks, or threadsmay be designed as if they

16、were to operate in isolation, each one producing and consuming mission information without explicit awareness of which other modules are currently operating. Communication relationships among such modules are self-configuring; this tends to minimize complexity in the development and operations of mo

17、dular data systems. A system built on this model is a society of generally autonomous interoperating modules that may fluctuate freely over time in response to changing mission objectives, module functional upgrades, and recovery from individual module failure. The purpose of AMS, then, is to reduce

18、 mission cost and risk by providing standard, reusable infrastructure for the exchange of information among data system modules in a manner that is simple to use, highly automated, flexible, robust, scalable, and efficient. This International Standard specifies the protocol procedures and data units

19、 that accomplish automatic configuration of AMS communication relationships, dynamic reconfiguration of those relationships during operations, and the use of those relationships to accomplish the exchange of mission information among data system modules. The scope and field of application are furthe

28、US MESSAGE SERVICE CCSDS 735.1-B-1 Page ii September 2011 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 are common to all

29、 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 issued by, and rep

30、resents 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 Recommended Standard. Estab

31、lishing 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 operational capability

32、. - 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 issuance, this Recommended

33、 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 Recommended Standard i

34、s 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 to direct planning

35、for its new standards and implementations towards the later version of the Recommended Standard.

36、ct space flight mission operations both in flight and on the ground increase in capability, the software operating on those computers tends to increase in functional scope and thus take on greater operational significance. With that increase in scope comes increasing size and complexity, which may b

37、e partially mitigated by decomposition into modules whose functionality can be readily defined and tested. However, this modularity in turn entails a growing reliance on effective communication among modules. That is, mere decomposition cannot diminish the functional complexity implied by complex re

38、quirements. It can only partition that complexity into manageable portions, while the resulting web of communication relationships among modules introduces new complexity of a different order: rather than a relatively simple system of a few increasingly large and complex modules, a modern mission is

39、 increasingly likely to require a large and complex system of relatively simple modules. Increasing complexity tends to increase the likelihood of failure. The increasing complexity of mission systems based on communication among modules therefore tends to increase the chance of such systems failing

40、 even as the success of those systems becomes increasingly critical to the achievement on mission objectives. Measures that can minimize the chance of failure in complex systemsexhaustive regression testing and configuration management, flight rules constraining the exercise of unproven system capab

41、ilities and the introduction of improvementsincrease cost if they are taken and increase risk if they are not. These considerations have led to the present recommendation for a standard system of communicationmessagingamong mission software modules. The objective of this proposed messaging standard

42、is to reduce mission cost and risk by confining much of the complexity of modern mission systems to relatively static and proven reusable infrastructure. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CCSDS shall not be held resp

43、onsible 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 de
