            The descriptions on the planes are as follows:
            •       5G Application and Service Plane
            The  5G  Application  and  Service  Plane  (5G-ASP)  enables  a  service-aware  behaviour  of  5G  network  in  a
            programmatic  manner  via  various  APIs  which  exposes  softwarized  network  capabilities.  It  consists  of
            application & service plane management support/softwarization/orchestration functional component that
            interacts with 5G multi-layer management function and multiple 5G application functional components that
            interacts with 5G Control Plane via standard interfaces.
            –       ASP Management Support, Softwarization, & Orchestration

            The ASP Management Support, Softwarization, and Orchestration (ASP-MSSO) softwarizes and orchestrates
            5G applications with the support of Multi-Layer Management.
            It  includes  applications  code  repository  management,  application  lifecycle  management  (creation,
            modification, and deletion), performance monitoring of applications to meet SLA requirements, detection,
                                                                                         rd
            isolation,  and  correction  of  application  faults,  and  security  management  of  3   party  applications
            (authentication and identity management).
            It  also  provides  the  capabilities  for  provisioning  of  ASP  resources  (resources  that  are  used  to  run  ASP
            applications) based on the requests received from the Management Plane. It coordinates provisioning of ASP
            service resources and network resources in Resource Layer in cross-layer manner and also performs atomic
            transactions to ensure the integrity of the requested provisioning service. ASP-MSSO provides capabilities
            for managing of ASP resources. It manages the capacity and performance related to each ASP service. ASP-
            MSSO obtains  resource  quality of  service  information  in  order to measure  and  record key  performance
            indicators (KPIs) for the ASP service. Capacity for an ASP service is allocated or de-allocated based on these
            KPIs.

            In case when virtual networks have been created by Softwarization capability, they are built with the support
            of the Control Layer, and may use the same Application Layer, or to attach an ASP instance to each virtual
            network.
