12、 October 2009 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 participants, and to formulate sound techni
13、cal 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 represents the consensus of, the CCSDS members.
14、 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 inaccord with the relevant Recommended Standard. Establishing such a standarddoes not preclude othe
15、r provisions which a member may develop.o Whenever a member establishes a CCSDS-related standard, that member willprovide other CCSDS members with the following information:- The standard itself. - The anticipated date of initial operational capability. - The anticipated duration of operational serv
16、ice. o Specific service arrangements shall be made via memoranda of agreement. Neitherthis Recommended Standard nor any ensuing standard is a substitute for amemorandum of agreement.No later than five years from its date of issuance, this Recommended Standard will be reviewed by the CCSDS to determi
17、ne 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 Standard is issued, existing CCSDS-related member standards an
18、d 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 for its new standards and implementations towards th
19、e later version of the Recommended Standard. ISO 10537:2016(E) ISO 2016 - All right reserverd BS ISO 10537:2016CCSDS RECOMMENDED STANDARD FOR ENCAPSULATION SERVICE CCSDS 133.1-B-2 Page iii October 2009 FOREWORD This document is a Recommended Standard for use in developing flight and ground systems f
20、or space missions and has been prepared by the Consultative Committee for Space Data Systems (CCSDS). The Encapsulation Service described herein is intended for missions that are cross-supported between Agencies of the CCSDS. This Recommended Standard specifies a communications service to be used by
21、 space missions to transfer protocol data units that are not directly transferred by the Space Data Link Protocols (references 1-4) over a ground-to-space or space-to-space communications link. The data units transferred with this service are encapsulated in either Space Packets, defined in referenc
22、e 5, or Encapsulation Packets, defined in this document. This Recommended Standard is developed from the Encapsulation Service that was defined in the Advanced Orbiting Systems (AOS) Recommended Standard (reference B2). In this Recommended Standard, that service is re-defined so that it can be used
23、with any of the Space Data Link Protocols (references 1-4). Also, the Encapsulation Packet that was defined in references B2-B4 is included in this Recommended Standard as an alternative packet structure for encapsulation. In order to define all Space Data Link Protocols in a unified way, a few tech
24、nical specifications of the Encapsulation Service in reference B2 have been changed. Also, some technical terms in references B2-B4 have been changed in order to unify the terminology used in all the CCSDS Recommended Standards that define space link protocols. These changes are listed in annex C of
25、 this Recommended Standard. Through the process of normal evolution, it is expected that expansion, deletion or modification to this document may occur. This Recommended Standard is therefore subject to CCSDS document management and change control procedures, as defined in reference B1. Current vers

41、Recommended Standard is to specify the Encapsulation Service. This service is to be used by space missions to transfer data units that are not directly transferred by the Space Data Link Protocols (references 1-4) over a ground-to-space or space-to-space communications link. 1.2 SCOPE This Recommend
42、ed Standard defines the Encapsulation Service in terms of: a) the service primitives provided to the users of this service;b) the protocol data units employed by the service provider; andc) the procedures performed by the service provider.It does not specify: a) individual implementations or product
43、s;b) the implementation of service interfaces within real systems;c) the methods or technologies required to perform the procedures; ord) the management activities required to configure and control the service.1.3 APPLICABILITY This Recommended Standard applies to the creation of Agency standards an
44、d to the future data communications over space links between CCSDS Agencies in cross-support situations. The Recommended Standard includes comprehensive specification of the service for inter-Agency cross support. It is neither a specification of, nor a design for, real systems that may be implement
45、ed for existing or future missions. The Recommended Standard specified in this document is to be invoked through the normal standards programs of each CCSDS Agency, and is applicable to those missions for which cross support based on capabilities described in this Recommended Standard is anticipated
46、. Where mandatory capabilities are clearly indicated in sections of the Recommended Standard, they must be implemented when this document is used as a basis for cross support. Where options are allowed or implied, implementation of these options is subject to specific bilateral cross support agreeme
47、nts between the Agencies involved.

48、osen, so that future evaluations of proposed changes or improvements will not lose sight of previous decisions. Concept and rationale behind the decisions that formed the basis for this Recommended Standard is documented in reference B5. 1.5 DOCUMENT STRUCTURE This document is divided into five numb
49、ered sections and three annexes: a) Section 1 presents the purpose, scope, applicability and rationale of thisRecommended Standard and lists the conventions, definitions, and references usedthroughout the document;b) Section 2 provides an overview of the Encapsulation Service;c) Section 3 defines the service primitives provided for this service;d) Section 4 specifies the protocol data units and procedures employed by the serviceprovider;e) Section 5 lists the managed parameters associ
