The pivotal deployment of 5G and network slicing has triggered the need for a radical change in the way networks and services are managed and orchestrated. Full end-to-end automation of network and service management has become an urgent necessity for delivering services with agility and speed and ensuring the economic sustainability of the very diverse set of services offered by Digital Service Providers. The ultimate automation target is to enable largely autonomous networks which will be driven by high-level policies and rules (AKA intent); these networks will be capable of self-configuration, self-monitoring, self-healing and self-optimization without further human intervention. All this requires a new flexible end-to-end architecture framework designed for closed-loop automation and optimized for data-driven machine learning and artificial intelligence algorithms. The ETSI ISG ZSM was formed with the goal to accelerate the definition of the required end-to-end architecture, and the presenter will introduce the ETSI ZSM architecture that was published on August 2019.
