Up in the Clouds: A Taxonomical Analysis of Network Management Functionalities From a Network as a Service Perspective
The externalization of network control and maintenance tasks, enabled by the emerging Networking as a Service (NaaS) paradigm, is an appealing opportunity for large Telcos to expand their network management offering to SMEs. In this paper, the authors propose an architecture for network control and management capable of efficiently supporting the NaaS paradigm. Their methodology is based on a set of orthogonal requirements that forms the platform to assess the admissibility of different network management functions in the remote management plane. Such assessments are realized based on the taxonomical evaluation of the management functions classified according to the requirements they impose on the remote management plane in terms of security and robustness.
