Optical access networks present several characteristics (tree-like topology, distributed shared access to the upstream channel, partial centralization of the complex operations in the OLT device) that make them appealing for the virtualization of some of their functionalities. We propose a novel EPON architecture where OLTs and ONUs are partially virtualized and migrated to the network core following SDN and NFV paradigms, thus decreasing CAPEX and OPEX, and improving the flexibility and efficiency of network operations.

Application of these calculates are optical signals with nano antennas, nano electronic device (Resistance, Inductance and Capacitor) and even nano scale negative-index optical structures.

The neutral host model is key for this vertical, specially to promote the infrastructure sharing between operators for a pervasive infrastructure deployment. However, it demands enhancements in today's virtualization technologies to support geographically scattered and resource constrained computing and networking elements (i.e., core data centers, edge computing point of presences, and far-edge servers at lampposts, etc.). This paper presents the virtualization enhancements developed within the H2020 5GCity project to support the neutral host model for smart city deployments. The envisioned virtualization technology demands security and technology extensions with a unified view of sliceable and heterogeneous devices and radio technologies (e.g., LTE, 5G, and Wi-Fi). In our solution, security is enhanced by deploying a robust compute node authentication, monitoring, and geo-tagging. In addition, wireless connectivity is extended via an innovative multiple RAN controller approach for the management and control of heterogeneous radio resources. In order to be validated, our virtualization approach is being deployed and demonstrated in the cities of Bristol, Barcelona, and Lucca.

By exploiting the concept of network slicing, as one key enabler in the transition to 5G, infrastructure and service providers can logically split a shared physical network into multiple isolated and customized networks to flexibly address the specific demands of those tenant slices. Motivated by this reality, the H2020 5GCity project proposed a novel 5G-enabled neutral host framework for three European cities: Barcelona (ESP), Bristol (UK), and Lucca (IT). This article revises the main achievements and contributions of the 5GCity project, focusing on the deployment and validation of the proposed framework. The developed neutral host framework encompasses two main parts: the infrastructure and the software platform. A detailed description of the framework im...

Passive Optical Networks (PON) have emerged as a viable option for 5G access and backhaul networks due to their cost effectiveness and high bandwidth. Improving the flexibility of network management is a key requirement of 5G, and Software Defined Networking (SDN), due to network programmability capabilities, is considered a key component of 5G. However, OpenFlow (OF), the current southbound SDN interface, has several limitations. P4 is a new language for Programming Protocol-Independent Packet Processors that promises to overcome OF’s limitations and brings in more flexibility for controlling the data plane of SDN devices. This paper presents a P4-based SDN architecture for PONs, by building a PON headend around a programmable P4 switch

To meet the needs of future communication, a paradigm shift both in the terrestrial and satellite segments is needed, transforming them from data-only transport media to intelligent services, equipped with computational, storage and decision-making capacities. In this article, we present H2020 SaT5G project vision to integrate the next generation satellite systems into 5G terrestrial networks at different levels. To this end, after highlighting the benefits of the integrated satellite-5G systems via some potential use ...

It enables a new range of features such as agile service provisioning, multi-tenancy, software controlled and dynamic management, on-demand service-oriented resource allocation, universal multi-access, and ubiquitous connectivity. Standardization bodies as 3GPP and ETSI recognize and promote terrestrial and satellite interworking. The complete integration can be achieved with the combination of radio networks, including core and access, and the satellite systems, with computational resources expanded from the core to the network’s edge. In this novel ecosystem, a coordination framework is an essential enabler to realize 5G vision. Combined management of different resources will be performed through a MANO-like framework, which is the focus of this paper. The proposed solu...

Service providers require seamless connectivity between terrestrial and satellite system, considering the best transport options available according to bandwidth, latency, network conditions and other application-specific requirements. The interworking between terrestrial and satellite is well recognized and promoted in the standardization bodies like 3GPP and ETSI. Full integration foresees coexistence of satellite system, with the radio networks (core and access) as well as computational resources expanded from the core to the network edge. A suite of orchestration of heterogeneous resources is fundamental enabler to realize this vision.

WDM has a high cost of initial set up and maintenance of the components, as well as power consuming. Considering end-user requirements (i.e. multi services, high bandwidth and performance), it is extremely essential to provide a framework to manage multi-wavelengths in PON networks. Software defined Networking (SDN) and Network Function Virtualization (NFV) paradigms are potential solutions, paving the way for efficient management and operation, enabling softwarization, virtualization and centralization of distributed functions. In this work, we proposed an SDN-based AI solution for managing the wavelength based on user requirements and daily internet usage patterns. For this, a monitoring module is used for telemetry and event collector. To make the best decision, all daily collected data will be sent to the AI layer.

The newest 3GPP study items under 5G created opportunity to integrate satellite systems, even beyond 5G networks. Integration between these two technologies will bring new range of features such as universal multi-access, dynamic management and ubiquitous connectivity, as well as increasing coverage, availability and reliability. This can be achieved through virtualization of satellite ground segment components, APIs and orchestration platform. In this work, we proposed an orchestration solution to manage and coordinate inter and intra satellite communication (i.e. GEO, MEO, LEO), together with terrestrial network resources. The solution is highly flexible and allows easy configuring of satellite systems including, baseband user segment, network user segmen...
