Closed Loop Automation for Telecom Cloud Infrastructure

Use cases & Demos for Closing the Loop for Telco Services with Hardware Infrastructure

Figure 1: Various Feedback Loops in a Virtualized Network Infrastructure [2]

Abstract

Transformation of network softwarization towards 5G inherently requires satisfying the requirements across a broad scope of verticals like virtualized infrastructure, Internet of Things (IoT), Edge Computing, Visual Cloud, etc., while maintaining Quality of Service (QoS) and Quality of Experience (QoE) criteria required to satisfy service constraints including latency. While individual aspects of telemetry, monitoring, service assurance, remote analytics, offline telemetry processing, observability, load balancing, etc., have always existed, there is an urgent need for ensuring these aspects work together across ETSI NFV [1] layers in a consistent, predictable & automated way in order to provide true capabilities of scalable and resilient closed loop automation. This articles shares various aspects of closed loop automation in 5G networks with emphasis on various closed loops possible and/or available and are common across various verticals. This article contextualizes telemetry & monitoring constraints, importance of closed loop across NFVI, common interfaces & APIs across MANO layer with reference to open source initiatives across OPNFV and ONAP communities to help…
