This Technical White Paper No.2 is about 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
• GANA Decision-Elements/Engines(DEs) as “AMC Services” that dynamically manage and control specific Managed Entities (MEs) embedded within NEs/NFs
• Collaboration/Coordination of Autonomic Functions (DEs) through synchronization of actions/policies on programming their corresponding Managed Entities (MEs)
• Multi-Layer Autonomics and the integration of the GANA Knowledge Plane with Orchestrators, SDN Controllers, Big-Data for Autonomic (closed-loop) Service Assurance, and OSS/BSS systems
• Overall ONAP to GANA Mappings and How ONAP can be used to implement GANA Knowledge Plane Components, and Advancing ONAP accordingly
• Using ONAP Components to Implement GANA Knowledge Planes and Advancing ONAP accordingly—using C-SON – ONAP Architecture as an illustration on GANA Knowledge Plane for the RAN (Radio Access Network)—an implementation by Cellwize
• Using ONAP with other Open Source Products to implement GANA Knowledge Planes for other Network Segments/Domains other than the GANA Knowledge Plane for RAN (C-SON)
• Federation of GANA Knowledge Planes for E2E Autonomic (Closed-Loop) Service Assurance across various network segments/domains
• On APIs (Application Programming Interfaces) that need to be considered in implementing a GANA Knowledge Plane
• Vendors’ Business View of the Overall 5G PoC: Supplying ONAP based GANA Knowledge Planes Software/Platforms for E2E Autonomic (Closed-Loop) Service Assurance for 5G Network Slices
