ITU-T X.501 (2008)/Cor.2 (04/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations

12、specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on t

13、hem with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU

14、-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 prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is use

15、d for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the

16、 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 express requirements. The use of such words does not suggest that compliance with the Recommendation is required of

17、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 Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Pro

18、perty 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 intellectual property, protected by patents, which may be required to implement this Recommendation. However, i

19、mplementers 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/.

21、1, 363, 370 and 371) 1) Correction of the defects reported in defect report 357 In clause 13.7.6 and Annex B replace the STRUCTURE-RULE information object with: STRUCTURE-RULE := CLASS , if it applies to any attribute type the object identifier or any attribute type (id-oa-allAttributeTypes) may be

22、used (defined in Annex B); In Annex B add to the end of the allocation of object identifiers for operational attributes: id-oa-allAttributeTypes OBJECT IDENTIFIER := id-oa 48 6) Correction of the defects reported in defect report 370 In clause 22.5 just before the note, add a new paragraph: The subo

23、rdinate references making up the root naming context are conceptually placed in DSA specific entries (DSEs) immediately subordinate to the root DSE (see 24.2). The DSE type shall be subr. 7) Correction of the defects reported in defect report 371 In clause 27.3.3, change the OP-BIND-ROLE information

Replace clauses 28.2, 28.3 and 28.4 with: 28.2 Establish Operational Binding operation 28.2.1 Establish Operational Binding syntax The Establish Operatio

27、nal Binding operation allows establishment of an operational binding instance of a predefined type between two DSAs. This is achieved through the transfer of the establishment parameters and the terms of agreement which were defined in the definition of the operational binding type. The arguments of

28、 the operation may be signed (see 17.3) by the requestor. If the target component of the SecurityParameters (see 7.10 of Rec. ITU-T X.511 | ISO/IEC 9594-3) in the request is set to signed and a result is to be returned, the result may be signed. Otherwise, the result shall not be signed. ISO/IEC 959

38、e of operational binding is to be established. An operational binding type is defined by an instance of the OPERATIONAL-BINDING information object class which assigns an object identifier value to the operational binding type. If the receiver does not recognize or support the operational binding typ

39、e, it shall return an operationalBindingError with problem unsupportedBindingType. The bindingID component, when present, shall hold an identification of the new operational binding instance. If the bindingID is absent within the operation argument, the responding DSA shall assign an ID to the opera

40、tional binding instance and return it in the bindingID component of the EstablishOperationalBindingResult data type. In either case, when establishing an operational binding, both the identifier and version components of the OperationalBindingID value shall be assigned and issued by the DSA making t

41、he assignment. The identifier component of the OperationalBindingID data type shall be unique for all operational bindings between any two DSAs. However, the DSA not making the assignment shall accept an identifier component that is only unique within a specific operational binding type. If the iden

42、tifier component specifies an identifier already in use for the particular binding type, the responding DSA shall return an operationalBindingError with problem duplicateID. NOTE A pre-edition 5 system may not follow the above rule for assigning identities. The accessPoint component shall specify th

43、e access point of the initiator for subsequent interactions. The initiator component shall specify the role the DSA issuing the Establish Operational Binding operation assumes. The semantics of the roles are defined as part of the definition of the operational binding type. It is a choice of three a

44、lternatives: The symmetric alternative shall be taken, if the type of operational binding requires identical roles for the two DSAs. The establishment parameter for the initiating DSA is determined by the OP-BIND-ROLE associated with the SYMMETRIC field of the instance of OPERATIONAL-BINDING informa

45、tion object class. If this alternative is chosen in the request, but the operational binding type specifies asymmetric roles, then the responding DSA shall return an operationalBindingError with problem notAllowedForRole. The roleA-initiates alternative may be taken if both roles may be the initiato

46、r of an asymmetric operational binding and it shall be taken when only the initiating DSA may take ROLE-A. The establishment parameter for the initiating DSA is determined by the OP-BIND-ROLE associated with ROLE-A field of the instance of OPERATIONAL-BINDING information object class. If the DSA in

47、ROLE-A is not allowed to initiate the operational binding, the responding DSA shall return an operationalBindingError with problem notAllowedForRole. If the responding system does not accept the role allocation, it shall return an operationalBindingError with problem roleAssignment. The roleB-initia

48、tes alternative may be taken if both roles may be the initiator of an asymmetric operational binding and it shall be taken when only the initiating DSA may take ROLE-B. The establishment parameter for the initiating DSA is determined by the OP-BIND-ROLE associated with ROLE-B field of the instance of OPERATIONAL-BINDING information object class. If the DSA in ROLE-B is not allowed to initiate the operational binding, the responding DSA shall return an operationalBindingError with problem notAllowedForRole. If the respo
