C-SON Evolution for 5G, Hybrid SON Mappings to the ETSI GANA Model, and achieving E2E Autonomic (Closed-Loop) Service Assurance for 5G Network Slices by Cross-Domain Federated GANA Knowledge Planes

This Technical White Paper No.1 is about Demo-1 and Demo-2 (of a series of Demos planned for 2018/2019 and beyond) of the ETSI PoC (Proof-Of-Concept) on 5G Network Slices Creation, Autonomic & Cognitive Management and E2E Orchestration; with Closed-Loop (Autonomic) Service Assurance for Network Slices; using the Smart Insurance IoT Use Case. The Technical White Paper covers the following key topics in the target of operationalizing the ETSI GANA Model Standard (ETSI TS 103 195-2) in the context of 5G Networks and reveals Gaps in Standards that should be addressed by the industry while implementing GANA autonomics (control-loops) in network architectures and associated management and control architectures. The following aspects are covered in the results of the PoC:

• Brief introduction to the ETSI GANA Model for Autonomic Networking, Cognitive Networking and Self-Management 3. Decision Elements (DEs) as the autonomic management and control services that dynamically(adaptively) program (configure) specific Management Entities (MEs) embedded within Network Elements (NEs) or Network Functions (NFs) or Services associated with an NF
• Collaboration/Coordination of Autonomic Functions (DEs) through synchronization of actions/policies on the programming of their corresponding Managed Entities (MEs)
• Multi-Layer Autonomics and the integration of the GANA Knowledge Plane with Orchestrators, SDN Controllers, and OSS/BSS systems
• Technical view of the Overall 5G PoC
• The Four 5G Applications considered in the Overall 5G PoC’s Network Slicing Use Cases
• 5G Slice Provider and Consumer Business View of the Overall PoC (consisting of multiple Demo Cases executed and in plan for 2018/2019 timeframe)
• Vendors’ Business View of the Overall 5G PoC: Supplying GANA conformant Software for E2E Autonomic (Closed-Loop) Service Assurance for 5G Network Slices and required Programmable Traffic Monitoring Fabrics and Solutions for Orchestrated Assurance
• Demo-1: Smart Insurance Providers as Key Requesters and Consumers of 5G Network Slices Delivered by Service Providers in fulfilment of Slice Requests (Showcase by QualyCloud)
• Demo-2: C-SON Evolution for 5G, Hybrid-SON Mappings to the ETSI GANA Model; Federation of GANA Knowledge Planes to achieve E2E Autonomic (Closed-Loop) Service Assurance for 5G Network Slices—through a Real Implementation by Cellwize
• ETSI-GANA Model as key Enabler for 5G: High Level Design Principle 13. Federation of GANA Knowledge Planes for E2E Autonomic (Closed-Loop) Service Assurance across various network segments/domains
• Summary of Further Plans on Demo series planned for the overall 5G PoC in the timeframe 2018/2019 and beyond
