Advanced communication networks, such as 5G and beyond, will be a complex ecosystem made of multiple physically interconnected elements, implying that the upcoming network will have to address capabilities such as flexibility, programmability and extensibility. This article, describes an Open and Extensible 5G Network Function Virtualisation (NFV) based Reference ecosystem of experimental facilities, named 5GinFIRE, that integrates existing facilities with new vertical-specific ones but also lays down the foundations for instantiation fully softwarised architectures of vertical industries and experimenting with them. Additionally, we present 5GinFIRE as the forerunner experimental playground, together with three uses cases, wherein new components, architecture designs and APIs may be tried and proposed before they are ported to more industrially mainstream 5G networks that are expected to emerge in large scale.
The always growing need, for innovative products, forces manufacturing plants to improve their ability to quickly respond to market requirements by designing competitive products and modifying existing ones. The function block concept, promises to improve productivity in terms of reuse, reliability, flexibility and interoperability. IEC, with standards like 61499, defines the basic concepts and a methodology for the design of modular, re-usable distributed Industrial Process, Measurement and Control Systems (IPMCSs). To support the whole life cycle of these systems, new function block oriented Engineering Support Systems (ESSs), are highly required. In this paper, we consider, the process of interconnecting heterogeneous fieldbus islands and, the design and implementation of integrated distributed applications over them. The architecture of the interworking unit was defined, to obtain interoperability in fieldbus level and to allow a uniform development of applications from the ESS point of view. A 4-layer architecture was also defined to facilitate the design and development of the new generation function block oriented ESSs.
Abstract-5G does not only aim at higher capacity and lower latency than current 4G in mobile broadband networks, but also to increase the level of programmability, control and flexibility to meet the requirements from innovative use cases such as IoT, smart manufacturing, and immersive media. However, several difficulties still need to be overcome for a better technological adoption. To reduce the time-to-market for networked services and to lower the entry barrier to third party developers of VNFs and network services, an integrated development and operations (DevOps) methodology is a promising way. One of the biggest challenges in upcoming 5G DevOps is the validation and verification (V&V) of individual VNFs and network services (VNF graphs) so that operators can be sure of their behavior. In this paper, we propose an NFV architecture that supports the DevOps methodology with a V&V platform and an advanced NFV catalogue. The conceptual components of the V&V platform, the foreseen methodology and the outcomes are explained. Finally, we explore some perspectives in applying such V&V approach in another 5G research project.
The IP Multimedia Subsystem (IMS) is an architectural framework for delivering IP multimedia services. The appearance of Software Defined Networks (SDNs) concept in the IMS fabric can unleash the potential of the IMS technology which enables access agnostic services including applications like video-conferencing, multi-player gaming, white boarding all using an all-IP backbone. SDN requires some method for the control plane to communicate with the data plane. One such mechanism is OpenFlow which is a standard interface for controlling computer networking switches. This work presents our experience and implementation efforts in integrating OpenFlow mechanisms within IMS. Since this work also is done within the Future Internet Research and Experimentation domain, we also describe how we enabled our infrastructures with experimentation mechanisms.
