This Technical White Paper No.3 is about Demo-3 (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 (KP) with other systems, e.g. with Orchestrators, SDN Controllers, and OSS/BSS or Configuration Management Systems – The Objectives being addressed by Demo-3 of the ETSI PoC – Capabilities of Big Switch Networks for Programmable Traffic Monitoring Fabrics that meet the Outlined Telecom Operators’ Requirements in line with the ETSI GANA Framework Principles – “Knowledge Plane-Driven” Orchestration—based on Business Goal Incentives or Autonomic Remediation Strategies Execution by the KP; and Selective Multi-Layer Programming Targets by KP Autonomics – Vendors’ Business View of the Overall 5G PoC – Four Examples of the 5G Applications being considered in the Overall 5G PoC’s Network Slicing Use Cases – Technical view of the Overall 5G PoC – QoS Framework on Flow-Oriented (Flow-Level) Services & Telemetry Services delivered within a specific 5G Slice Type and varying in QoS Classes; Prioritization of Slices; and Definitions of QoS Classes and SLAs as inputs to Autonomic Service Assurance – ETSI-GANA Model as key Enabler for 5G: High Level Design Principle – Federation of GANA Knowledge Planes for E2E Autonomic (Closed-Loop) Service Assurance across the various network segments/domains – Conclusions – Further Work (beyond Demo-3) on Programmable Traffic Monitoring Services in NFV environments – On ETSI TC INT AFI WG and its Liaisons with other SDOs/Fora on GANA Autonomics in various Architecture Scenarios
