5、 in the Technical Report ISO/IEC TR 10000. The purpose of an International Standardized Profile is to recommend when and how certain information technology standards shall be used. ISOAEC ISP 12068 specifies application profile FDI 4 as defined in the Technical Report ISOAEC TR 10000-2. ISOllEC ISP
6、12068 is one of a set of International Standardized Profiles relating to the Directory (see ISOllEC TR 10000-2). It specifies the schema of information for the OSI TP application to be stored in the Directory according to ISO/IEC 9594. ISOAEC ISP 10616 profiles information to be stored within the Di
7、rectory which is common to a variety of applications. This ISP augments that information with OSI TP specific information. Statements and conformance requirements stated in ISP for the information profiled by ISOAEC ISP 10616 are also valid for the OSI TP specific information profiled by this ISP. I
8、SOAEC ISP 12068 specifies the use of the Directory for OSI TP, using existing object class and attribute type definitions from the Directory specifications themselves, and additional definitions. These existing and additional definitions are also intended to support the use of the Directory by users

This part of ISOllEC ISP 12068 defines those additional information which are needed to retrieve basic addressing information for applications using the OSI TP service. 1.2 Position within the taxonomy ISO/IE
14、C ISP 12068 is identified in ISOllEC TR 10000-2 as “Information technology - International Standardized Profile FDI 4 - Directory data definitions - Use of the Directory for OSI TP. 1.3 Scenario An OSI TP application, by means of its associated DUA, obtains Directory information by accessing directl

17、y and Illustrative Representation of LAN MAC Addresses An illustrative (in hexadecimal) representation of LAN MAC addresses has been defined ISO/IEC 10039 and is used throughout this Technical Report.

19、f LAN MAC Addresses The 48-bit address (universal or local) is represented as a string of six octets. The octets are displayed from left to right, in the order that they are transmitted on the LAN medium, separated by hyphens. Each octet of the address is displayed as two hexadecimal digits. The bit
20、s within the octets are transmitted on the LAN medium from left to right. In the binary representation the first bit transmitted, of each octet, on the LAN medium is the least significant bit of that octet. The Individual/Group address bit is the least significant bit. The left-most bit of the binar
21、y representation (Individual/Group address bit) of a MAC address distinguishes individual from group addresses. The Universally/Locally administered address bit is the next bit following the Individual/Group address bit. The U/L bit indicates whether the MAC address has been universally or locally a
22、ssigned. For the previous example, the first octet transmitted is AC and the last octet transmitted is 80. The first bit transmitted is the low order bit of AC, a zero. The last bit transmitted is the high order bit of 80, a one. 5 Standard Group MAC Addresses 5.1 General All MAC protocol data units
23、 contain addressing information. The addressing information consists of two fields: the destination MAC address and the source MAC address. Both of these address fields are 48-bit fields; the structure and semantics of the address field are defined in ISO/IEC 10039. 2 Copyright International Organiz

A feature (object class, attribute type, attri
26、bute syntax) is supported by a DSA implementation if the DSA is able to process the feature in accordance with the base standard or as specified ISOllEC ISP (see also clauses 8, 9 and 10). 4.2.2 optionally supported; o : The support of the feature (object class, attribute type, attribute syntax) is

29、ted in ISO/IEC ISP 10616. In addition, a Directory System Agent shall after suitable set up be capable of storing, modifying and retrieving entries which fulfill all of the following conditions : - the entry lies within the scope of the minimum set of structure and naming elements specified in claus

The requirements formulated in ISO/IEC ISP 10616 with respect to supported object classes, supported attribute types and supported attribute syntaxes according to ISOllEC ISP 1
33、0616 are also valid for the additional supported object classes, supported attribute types and supported attribute syntaxes according to this part of ISO/IEC ISP 12068. 6.2 DUA conformance DUAs typically need schema information as outlined in this part of ISO/IEC ISP 12068 to support Use of the Dire
34、ctory for OSI TP. However, this part of ISO/IEC ISP 12068 makes no statements about DUA conformance. 7 DIT structure The purpose of this clause is to relate information specified in ISO/IEC ISP 12068 to the minimum set of structure and naming elements defined in ISOllEC ISP 10616 and thus to provide
35、 locations for entries of selected object classes. The DIT structure which shall as a minimum be supported by implementations claiming conformance to ISO/IEC ISP 12068 is that defined in ISO/IEC ISP 10616 and in clause 8 and 9. The DIT structure which shall as a minimum be supported by implementatio
36、ns claiming conformance to ISOllEC ISP 12068 is the superset of - structure elements listed in ISO/IEC ISP 10616, and - structure elements listed in A.6.5.1. This DIT structure is supported in the sense that a conformant DSA shall be capable of storing, modifying and retrieving entries which are par
37、t of a tree with this structure (for a more formal definition see ISO/IEC ISP 10616). 8 Object classes The following object class shall be supported in addition to those specified in ISO/IEC ISP 10616: - tpsu To define the application entity objects that are the objects stored in the Directory descr
38、ibing OSI TP entities, it is necessary to have Object Identifiers to identify the various objects and attributes.
