9、 authorities: General procedures and top arcs of the international object identifier tree Summary Recommendation ITU-T X.660 | ISO/IEC 9834-1 defines a tree structure that supports international object identifiers (OIDs). It includes registration of the top-level arcs of the OID tree. It also specif

10、ies procedures for the operation of an International Registration Authority for use, when needed, by other ITU-T Recommendations and/or International Standards. For easy reference, and to emphasize that this tree is an extended form of the original OID tree (defined in earlier versions of this Recom

11、mendation | International Standard), this specific tree can be referred to as “the International Object Identifier tree“, or more commonly as just “the OID tree“. The original OID tree required all arcs to be unambiguously identified by a primary integer value, with the use for human readability of

12、(not necessarily unambiguous) secondary identifiers (restricted to the Latin alphabet). Secondary identifiers were not normally carried in protocols or used for machine identification. The international object identifier tree extends this by allowing an arc to also be unambiguously identified by a U

13、nicode label (a string of Unicode characters) that can be carried in protocols and can be used for machine identification. The primary integers and secondary identifiers of the international object identifier tree continue to be used in encodings (primary integer values only) and value notation (pri

14、mary integer values and secondary identifiers) of the ASN.1 OBJECT IDENTIFIER type, which is unchanged. The Unicode labels can only be used in encodings and value notation of the ASN.1 OID-IRI type. This Recommendation | International Standard also provides recommendations on an appropriate fee stru

15、cture for registration of lower level arcs.

16、17 ii Rec. ITU-T X.660 (07/2011) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of I

17、TU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics

18、for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepare

19、d on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may c

20、ontain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to expr

21、ess requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Prop

22、erty Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of

23、 intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2012 A

32、erarchical structure of Registration Authorities, called the international OID tree, which supports the ASN.1 OBJECT IDENTIFIER type and the ASN.1 OID-IRI type (see Rec. ITU-T X.680 | ISO/IEC 8824-1); b) registers top-level arcs of the international object identifier tree; c) specifies procedures wh

33、ich are generally applicable to registration at any level of the international OID tree; d) provides guidelines for the establishment and operation of International Registration Authorities for use, when needed, by other ITU-T Recommendations and/or International Standards; e) provides guidelines fo
