            The OSS-NS functional components encompass the set of operational-related management capabilities that
            are required in order to manage and control network services offered to customers as part of NaaS services.
            See clause 7.8.2.1 for a description of OSS-NS functionalities.
            Figure 8-4 shows the OSS-NS functional components.






















                                         Figure 8-4 – OSS-NS functional components


            The OSS-NS functional components include:
            –       NS catalogue;
            –       NS provisioning;
            –       NS monitoring and reporting;
            –       NS policy management;
            –       NS automation;

            –       NS level management;
            –       NS incident and problem management;
            –       NS inventory.

            8.3.2.1    NS catalogue
            The NS catalogue functional component provides a listing of all network services of the NaaS CSP. The NS
            catalogue contains and /or references all relevant technical information required to deploy, provision and
            run a network service.
            8.3.2.2    NS provisioning

            The NS provisioning functional component provides the capabilities for provisioning network services, both
            in terms of the provisioning of network service implementations and of network service access endpoints
            and the workflow required to ensure that elements are provisioned in the correct sequence.

            8.3.2.3    NS monitoring and reporting
            The NS monitoring and reporting functional component provides capabilities for:
            –       Monitoring the activities of other functional components throughout the NaaS CSP's system. This
                    includes functional components involved in the support of network services, such as functional
                    components in the OSS-NS itself like the NS automation functional component (e.g., the provisioning
                    of a network service instance for a particular customer).
            –       Providing reports on the behaviour of the NaaS CSP's system, which can take the form of alerts for
                    behaviour which has a time-sensitive aspect (e.g., the occurrence of a fault, the completion of a
                    task), or it can take the form of aggregated forms of historical data (e.g., service usage data).
            –       Storage and retrieval of network service monitoring and event data as logging records.
