High Level Objectives for Casablanca: Deployment of the hybrid 5G Radio Network (PNFs & VNFs) Complete PNF Support Platform Enhancements to Deploy Edge Virtual Radio Network Functions (e.g. CU) Creation & Management of Radio Network Slice Subnet within the deployed network Lifecycle management of Radio Network Slice Subnet Instances Optimization of the deployed 5G network and the slices Near-real Time Data Collection (e.g. streaming) Edge Analytics to Support 5G Network Optimization OOF enhancements for optimal placement of edge resources

A: 5G Radio Network Deployment Requirements Description Disaggregated 5G RAN may include PNFs and VNFs, in which case cloud infrastructure deployment at the edge is required. Beijing implemented the first phase of PNF discovery and instantiation. Our goal for Casablanca is expand on that work, include VNF deployment at the edge, and fully integrated lifecycle management. Key enhancements needed are: Support full Application level Configuration (+Ansible), allow various mobile network elements to be controlled from same controller persona created from CC-SDK Add Lifecycle management functions to controller persona Support an integrated configuration design tool in SDC that can be used with any controller persona (next gen CDT) Add support for PNF Software Management and Change management Edge Cloud Support Add needed support for deploying Mobility Virtual Network Elements (e.g. CU) at the Edge locations Further automation of PnP Discovery for PNF Rationale Support for deploying and managing 5G mobility network is critically important for most ONAP members.

B: Radio Network Slice Management – ONAP Requirements Description Many providers are interested in using ONAP for slice management and extending the cloud notion of sharing network/compute/storage to sharing network functions and network slice subnet instances . 3GPP standards are still evolving and early versions are not expected to be available before June 2018. However, we would like to demonstrate these concepts in ONAP initially using a simple slice definition, creation, and management for 5G Radio Network. Radio Access Network slice subnet instances supported and demonstrated in Casablanca will be limited to simple examples such as eMBB (enhance Mobile Broad Band). Key enhancements needed are: Enhance SDC to model & define network slice subnets for Radio network Enhance SO Instantiate and lifecycle manage network slice subnet instances Enhance A&AI to inventory and store state of slice segments Integrated design (e.g. configuration and service designs) Support Complex Service Modeling (e.g. service composition, nested allotted resources) Define and instantiate monitoring and management of network slice subnet instances, network slice instances Rationale (why R2?) Typical carrier deployments will be complex enough to need support for nested / complex services, correlation across multiple elements - hence, these are critical functional requirements for a carrier-grade ONAP Impacted ONAP components SDC, SO, CC-SDK (SDN-C, APP-C), AAI, DCAE Participating Companies AT&T Amdocs China Mobile Ciena Cisco Ericsson Huawei Intel Nokia
