38、oning of network services across multiple administrative domains 4.1 Introduction NFV-MANO services can be offered and consumed across multiple administrative domains. Those administrative domains can be mapped to different organizations, e.g. different network operators or different departments of

39、the same network operator. Based on the study output of ETSI GR NFV-IFA 028 i.1, multiple administrative domain aspect includes the case of network service offered by multiple administrative domains. The concept of composite NS and nested NS as specified in ETSI GS NFV-IFA 010 2 is utilized. Referen

40、ce point Or-Or is provided in NFV-MANO architecture for supporting the interoperability in this case. The Or-Or reference point is used for the exchanges between NFVOs in different administrative domains, and supports the following interfaces: Network Service Descriptor (NSD) Management; Network Ser

41、vice (NS) Lifecycle Management; NS Lifecycle Operation Granting; NS Instance Usage Notification; NS Performance Management; NS Fault Management. ETSI ETSI GS NFV-IFA 030 V3.1.1 (2018-09) 8 The information elements exchanged via the interfaces above are also part of the present document. 4.2 Relation

42、 to other NFV group specifications The present document is referencing information from the following ISG NFV Group Specifications: Management and Orchestration - Functional requirements specification ETSI GS NFV-IFA 010 2: - Interfaces associated with the Or-Or reference point are based on the func

43、tional requirements specified in ETSI GS NFV-IFA 010 2 for the NFVO. Management and Orchestration - Os-Ma-Nfvo reference point Interface and Information Model Specification ETSI GS NFV-IFA 013 1: - The NSD Management, NS Lifecycle Management, NS Performance Management and NS Fault Management interfa

44、ce on the Or-Or reference point are based on corresponding interfaces defined in ETSI GS NFV-IFA 013 1. For NSD Management and NS Lifecycle Management interface, only a subset of operations in ETSI GS NFV-IFA 013 1 is applied on the relate interfaces of the Or-Or reference point. 4.3 Conventions The

45、 following notations, defined in ISO/IEC 9646-7 i.2, are used for the qualifier column of interface information elements: M mandatory - the capability is required to be supported; O optional - the capability may be supported or not; CM conditional mandatory - the capability is required to be support

46、ed and is conditional on the support of some condition. This condition shall be specified in the Description column; CO conditional optional - the capability may be supported or not and is conditional on the support of some condition. This condition shall be specified in the Description column. The

47、following notation is used for parameters that represent identifiers, and for attributes that represent identifiers in information elements and notifications: If parameters are referring to an identifier of an actual object, their type is “Identifier“. If an object (information element or notificati

48、on) contains an attribute that identifies the object, the type of that attribute is “Identifier“ and the description states that the attribute is the identifier of that particular notification or information element. EXAMPLE 1: Identifier “resourceId“ of the “NetworkSubnet information element“ has t

49、ype “Identifier“ and description “Identifier of this NetworkSubnet information element“. If an object (information element or notification) contains an attribute that references another object or objects defined in an ETSI NFV GS, the type of the attribute is “Identifier“, followed by the list of objects it references. EXAMPLE 2: “Identifier (Reference to Vnfc)“ or “Identifier (Reference to Vnfc, Virtual Link (VL) or VirtualStorage)“. If the type of a parameter or attribute has been marked as “Not spec
