Introduction

The Policy Manager is the entity of the service platform responsible for runtime policies enforcement over the deployed network services. Policies enforcement regard mainly elasticity actions (scaling in and out VNFs), events identification and triggering of relevant alerts as well as security actions (e.g. application of a firewall rule). It consists of a set of components supporting the formulation of the policies and their enforcement, including the interfaces for interaction with the 5GTANGO monitoring framework,the message broker for publication and consumption of monitoring data, alerts and suggested actions, the catalogue and repository databases,the gatekeeper and the MANO orchestration mechanisms.

The objective is to support the injection of intelligence in the various MANO orchestration mechanisms by exploiting inference mechanisms over the collected data in real-time. Inference mechanisms are applied over a set of rules that specify what action can be enforced upon the fulfilment of set of conditions. In this way, runtime policies design can be realised by service providers, targeted at runtime management of network services as well as network slices. Conflict resolution mechanisms are also available, promoting the enforcement of policies with higher priority in case of conflicts.
