7、to support the management of the Virtual Private Network Service as outlined in ITU-T M.3208.3. Source ITU-T Recommendation M.3108.3 was prepared by ITU-T Study Group 4 (2001-2004) and approved under the WTSA Resolution 1 procedure on 19 January 2001. ii ITU-T M.3108.3 (01/2001) FOREWORD The Interna
8、tional Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. 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 Recommendati
9、ons 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 for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approva
10、l 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 prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration
11、“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. 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
12、. 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 intellect

19、GDMO-based information model to support the management of the Virtual Private Network Service as outlined in ITU-T M.3208.3. 1.2 Purpose The purpose of this Recommendation is to support the standard interfaces, across the X-interface, between service customers and service providers for the purposes
20、of managing the virtual private network services in the service management layer of the TMN. It specifically intended to support the requirements provided in ITU-T M.3208.3. 1.3 Application This Recommendation is applicable to the interfaces between systems that participate in the ordering and the m
21、anagement of the virtual private network services. 2 References The following ITU-T Recommendations, and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

Clause 6 p
30、rovides the formal definition of the GDMO-based information model. The management of a VPN service starts when a Service Customer (SC) requests the service. This can be achieved by the SC requesting SP to create an instance of vpnService. The SP then informs the SC of the availability of the request
31、ed service through a notification of the creation of an instance of vpnService. ITU-T M.3108.3 (01/2001) 3 After the SC has been notified about the creation of the vpnService instance, the SC can modify the service through management operations for some attributes. An instance of the networkR1 is us
32、ed for naming. All entries in that MOI can be changed only by the SP, though the SC can read (GET) such information. A vpnService MOI contains zero or more serviceAccessGroups, though a vpnService MOI containing less than two serviceAccessGroups is not very useful. The SC can create instances of ser
33、viceAccessGroup MOC. A serviceAccessGroup MOI contains zero or more SAPs. A serviceAccessGroup MOI is created without any SAPs. After creation a instance of serviceAccessGroup, the SC can add or remove SAPs from the serviceAccessGroup. The SC can identify some or all of the SAPs desired in a service
34、AccessGroup. If the SC adds to a serviceAccessGroup more SAPs than are explicitly identified, then the SP assigns additional SAPs, from the same service location to the serviceAccessGroup, and informs the SC about the identity of those SAPs. The SC can add or remove SAPs from a serviceAccessGroup th
35、rough management operations. After the requested VPN service has been implemented by the SP, the SC can request the creation of one or more VPN Leased Circuit in the VPN service. The VPN Leased Circuit connects the VPN service access points that are included in the specified service access groups. T
36、he SC can create instances of vpnLeasedCircuit MOC. Figures 5-1 and 5-2 represent the inheritance of the MOCs and the containment relationships of the MOIs respectively. Inheritance and containment are not shown for all of the MOs that are imported from other Recommendations. Figure 5-2 does not sho
