Cloud-network slicing is a promising approach to serve vertical industries delivering their services over multiple administrative and technological domains. However, there are numerous open challenges to provide end-to-end slices due to complex business and engineering requirements from service and re-source providers. This article presents a reference architecture for the cloud-network slicing concept and the practical realization of the Slice-as-a-Service paradigm, which are key results from the NECOS (Novel Enablers in Cloud Slicing)project. The NECOS platform has been designed to consider modularity, separation of concerns, and multi-domain dynamic operation as prime attributes. The architecture comprises a set of inter-working components to automatically create, manage,and decommission end-to-end Cloud-Network slice instances in a lightweight manner. NECOS orchestrates slices at run-time,spanning across core / edge data centres and wired / wireless net-work infrastructures. The novelties of the multi-domain NECOS platform are validated through three proof-of-concept experiments: (i) a touristic content delivery service slice deployment featuring on-demand virtual infrastructure management across three countries in different continents to meet particular slice requirements; (ii) intelligent slice elasticity driven by machine-learning techniques; and (iii) marketplace-based resource discovery capabilities.

The authors would like to thank the Editor and the anonymous reviewers for their valuable comments and suggestions as well as the whole NECOS team and stakeholders. |
