A monitoring framework for 5G service deployments

Network softwarization - through the adoption of Software Defined Networking (SDN), Network Functions Virtualization (NFV) and Cloud-Fog computing technologies - is deeply impacting telecom and ICT industries. This transformation, along with numerous advantages, brings also considerable challenges. In this paper, we discuss the main features of monitoring in the afore-mentioned landscape as well as the main requirements imposed to resource monitoring systems for supporting future 5G deployments and services. Moreover, a generic architecture for monitoring both physical and virtual resources, either SDN/NFV-compliant or legacy, is presented and its main components are discussed. Finally, a preliminary implementation of a monitoring framework is presented that follows the identified design principles.
