From Automation to Autonomous: Driving the Optical Network Management to Fixed Fifth-generation (F5G) Advanced

abstract-An autonomous optical network operates with little or no human involvement and has the capability to configure, oversee, and sustain itself without external intervention. This paper presents the latest advances of autonomous networking (AN) proposed in TM Forum for optical networks. Each step in the procedure for the operator’s daily work is mapped into the AN framework, with detailed features specified in each level. The solution is based on a standard architecture and data models specified in IETF, known as Abstraction and Control of Traffic Engineering Networks (ACTN). Use cases are presented and conducted. This paper presents the result in three typical use cases for optical network management and maintenances: optical service provisioning, healthy assurance, and intelligent alarm processing.
