8、nization for Standardization) is a worldwide federation of national standards 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 establis
9、hed has the right to be represented on that committee. International organizations, 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

BS ISO 21323:2016CCSDS RECOMMENDED STANDARD FOR CCSDS BUNDLE PROTOCOL SPECIFICATION CCSDS 734.2-B-1 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 Committe
16、e meets periodically to address data systems problems that 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 consi
17、dered binding on any Agency. This Recommended Standard is 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, t
18、his standard will be inaccord with the relevant Recommended Standard. Establishing such a standarddoes not preclude other 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 s
19、tandard itself. - The anticipated date of initial operational capability. - The anticipated duration of operational service. o Specific service arrangements shall be made via memoranda of agreement. Neitherthis Recommended Standard nor any ensuing standard is a substitute for amemorandum of agreemen
20、t.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) remain in effect without change; (2) be changed to reflect the impact of new technologies, new requirements, or newdirections; or (3) be retired or cancel
21、ed.In those instances when a new version of a Recommended 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 modifi
22、ed. Each member is, however, strongly encouraged to direct planning for its new standards and implementations towards the later version of the Recommended Standard.

23、 734.2-B-1 Page iii September 2015 FOREWORD Attention is 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 reason
24、able 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 rights. Through the process of normal evolution, it is expected that expansion, deletion, or modification of this document may occur. This Reco
25、mmended Standard is therefore subject to CCSDS document 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).

34、that is communication-resource poor and is subject to long latencies and/or temporary network partitions, regardless of complexity. It is intended that this Recommended Standard become a uniform standard among all CCSDS Agencies. In addition, this specification exists to utilize the underlying servi
35、ce of various internetworking protocols both onboard and in transit between ground and space-based assets. This Recommended Standard is intended to be applied to all systems that claim conformance to the CCSDS Bundle Protocol. It is agnostic to the choice of underlying transmission protocol in that
36、BP can function over AOS, Space Packet, Proximity-1 Space Link Protocol, and various Internet and ground based protocols. The CCSDS believes it is important to document the rationale underlying the recommendations chosen, so that future evaluations of proposed changes or improvements will not lose s
37、ight of previous decisions. The concept and rationale for the use of a bundle protocol in space links may be found in reference H1. 1.3 ORGANIZATION OF THIS RECOMMENDED STANDARD This Recommended Standard is organized as follows: Section 2 contains an overview of the Bundle Protocol and the reference
38、s from which it is derived. Section 3 contains the CCSDS modification to RFC 5050. Section 4 contains the service descriptions. Section 5 contains services BP requires of the system.

As used in this Recommended Standard those te
42、rms are to be interpreted in a generic sense, i.e., in the sense that those terms are generally applicable to any of a variety of technologies that provide for the exchange of information between real systems. Those terms are: indication; primitive; request; response. 1.4.2 DEFINITIONS FROM OSI BASI
43、C REFERENCE MODEL This Recommended Standard makes use of a number of terms defined in reference 3. As used in this Recommended Standard those terms are to be understood in a generic sense, i.e., in the sense that those terms are generally applicable to any of a variety of technologies that provide f
44、or the exchange of information between real systems. Those terms are: entity; Protocol Data Unit (PDU); service; Service Data Unit (SDU).

45、er 2015 1.4.3 DEFINITIONS FROM RFC 5050 1.4.3.1 Overview This Recommended Standard makes use of a number of terms defined in reference 1. Some of the definitions needed for section 2 of this document are reproduced here for convenience. A graphical representation of a bundle node is given in figure
46、1-1. A bundle node is any entity that can send and/or receive bundles. Each bundle node has three conceptual components described in more detail below: a bundle protocol agent, a set of zero or more convergence layer adapters, and an application agent. The major components are illustrated in figure
47、1-1 and include the addition of storage for enqueued traffic and a Management Information Base (MIB) element. Figure 1-1: Graphical Representation of a Bundle Node It should be noted that there is one application agent per conceptual bundle node. That application may register in multiple endpoints (
48、may provide multiple endpoint identifiers to the bundle protocol agent, requesting delivery of bundles to any of those endpoints). 1.4.3.2 RFC 5050 Terms bundle: A protocol data unit of the DTN Bundle Protocol. NOTE Each bundle comprises a sequence of two or more blocks of protocol data, which serve
49、 various purposes. Multiple instances of the same bundle (the same unit of DTN protocol data) might exist concurrently in different parts of a network, possibly in different representations, in the memory local to one or more bundle nodes, and/or in transit between nodes. In the context of the operation of a bundle node, a bundle is an instance of some bundle in the network that is in that nodes local memory. ISO 21323:20
