R1 | Support for PNF - Onboarding | 1 | Disaggregated 5G RAN consists of hybrid network elements (PNF and VNF) and will require a cloud infrastructure deployment at the edge. This sub-case will expand/enhance ONAP capabilities to support limited lifecycle management aspects of PNF (including enhancements in SDK / certification, PNF onboarding, and SO, DCAE, A&AI support for PNF). This requires addressing the missing platform capabilities: 2.Enhance SDC (e.g. PNF onboarding) | 5G | New | SDC, AAI | For details on items 1,2,3,4,5 in Summary, please see: https://wiki.onap.org/display/DW/Missing+Platform+capabilities Scaled carrier deployments will include some PNFs to meet specialized requirements - hence, support for PNF is a critical requirement for a carrier-grade ONAP | Modeling / On-boarding | 5G SubCase1 participants: AT&T Wind River | |

R4 | Slice Management - Orchestration & Control | 1 | Many providers are interested in using ONAP to manage the general concept of Slicing (Extending the cloud notion of sharing network/compute/storage to sharing network functions and Services implemented across PNFs & VNFs). Supporting such a generic slicing concept could require ONAP enhancements in the areas of SDC/AAI modeling and service definition, lifecycle management of slices (whether done within the existing SO/controller context or via a new layer of control e.g. slice controller) since slices could have their own state, metrics and scaling procedures different and distinct from those of the underlying network functions (e.g. service/slice across multiple NFs from different providers). This requires addressing the missing platform capabilities: | 5G | Enhancement | SDC, SO, SDN-C, APP-C, Portal | For details on items 2,3,4,5,6,7,8 in Summary, please see: https://wiki.onap.org/display/DW/Missing+Platform+capabilities Typical carrier deployments will be complex enough to need support for nested / complex services, service aggregation, service path, correlation across multiple services - hence, these are critical functional requirements for a carrier-grade ONAP | Modeling / On-boarding | 5G SubCase2 participants: AT&T Wind River ZTE | |

R8 | Optimization - Configuration & Control | 2 ? | Many providers are interested in flexibly deploying network optimization functions from various vendors into the ONAP framework. We need such an ONAP Optimization Framework (OOF) to support two aspects. The first one is for the optimal placement of 5G virtual network functions. The second one is for performance optimization, where SON is a key functionality. | 5G | Enhancement |
SDC, SO, SDN-C, APP-C, Policy, Portal | Typical carrier deployments are expected to be very distributed requiring low-latency data collection & policy-based analysis at the edges (potentially across different clouds) - hence need for OOF enhancements for optimal placement of resources and multi-cloud, Policy framework enhancements for conflict resolution, DCAE scalability enhancements for high-volume & low-latency collection & analysis are critical to make ONAP carrier grade | Optimization | 5G SubCase3 participants: AT&T Amdocs Wind River | |||
