Creating Tailored and Adaptive Network Services with the Open Orchestration C-RAN Framework

Next generation wireless communications networks will leverage software-defined radio and networking technologies, combined with cloud and fog computing. A pool of resources can then be dynamically allocated to create personalized network services (NSs). The enabling technologies are abstraction, virtualization and consolidation of resources, automatization of processes, and programmatic provisioning and orchestration. ETSI's network functions virtualization (NFV) management and orchestration (MANO) framework provides the architecture and specifications of the management layers. We introduce OOCRAN, an open-source software framework and testbed that extends existing NFV management solutions by incorporating the radio communications layers. This paper presents OOCRAN and illustrates how it monitors and manages the pool of resources for creating tailored NSs. OOCRAN can automate NS reconfiguration, but also facilitates user control. We demonstrate the dynamic deployment of cellular NSs and discuss the challenges of dynamically creating and managing tailored NSs on shared infrastructure.Comment: IEEE 5G World Forum 201

Development of an orchestrator layer for a wireless cloud

In the last years mobile devices have gained much popularity, that's why the current mobile infrastructure is becoming obsolete. Cloud-RAN arises as an excellent candidat to overcome the strong limitations of the existing infrastructure as it uses a centralized administration of the resources. However, the implementation of such infrastructure presents a significant challenge due to the strict real time requirements of the wireless standards and the implementation of efficient administration algorithms. In order to provide solutions to the problems presented above, in this project we have focused on the implementation of a Cloud-RAN infrastructure. Specifically, we have focused on the study of algorithms that allows a better use of the wireless resources. Later, we have carried out a study to analyse the feasibility of the proposed infrastructure and we have compared it with the current infrastructures. Results obtained show that Cloud-RAN allows a better management of the wireless resources thanks to its flexibility and the fact that it is totally reconfigurable. Furthermore, its implementation reduces the CAPEX/OPEX costs significantly with respect to the current infrastructure
