The fifth generation (5G) of mobile networks is seen as a key enabler to support the introduction of digital technologies in multiple sectors, empowering different verticals and enabling new business models. Thanks to native capabilities of 5G networks, especially network slicing, edge computing and multi-tenancy, highly integrated telecom...

Fifth generation (5G) mobile networks will lead to a deep integration between networks and applications. Through novel paradigms like network functions virtualization and edge computing, the new classes of heterogeneous application services will be enabled to run close to the mobile end-user devices with zero-perceived latency and...

Network softwarization has paved the way for 5G technologies, and a wide-range of (radically new) verticals. As the telecommunications infrastructure evolves into a sort of distributed datacenter, multiple tenants such as vertical industries and network service providers share its aggregate pool of resources (e.g., networking, computing, etc.)...

Low latency and integration with edge computing facilities are two of the main enablers of the upcoming fifth-generation mobile network. The geographical distribution of virtualized compute and storage resources (e.g., NFVI PoPs) allows to deploy application/service instances/components closer to mobile subscribers, and to provide much higher...

5G is expected to bring forth disruptive indus-trial-societal transformation by enabling a broad catalog of (radically new, highly heterogeneous) applications and services. This scenario has called for zero-touch network and service management (ZSM). With the recent advancements in artificial intelligence, key ZSM capabilities such as the...

Since the adoption of virtualization paradigms is seen as a viable way to fulfil the requirements of next-generation applications in a sustainable way, this paper examines the virtualization of the Radio Access Network (RAN), focusing on the C-RAN architecture, in order to better understand the impact of NFV technologies on power consumption...

In an attempt to assess the suitability of current Infrastructure-as-a-Service (IaaS) technologies for fulfilling 5G-ready applications requirements, this paper has exploited the CNIT S2N testbed to perform a validation over a complete 5G ecosystem. The testbed supports the telecom network platform developed within the MATILDA Project, which...

While the integration of fourth-generation (4G) networks with Edge Computing technologies would anticipate the improvements foreseen by the coming of 5G, as well as smoothen the transition to the new technology, 4G does not natively support Edge Computing. Therefore, specific functionalities for user-plane integration and isolation of tenant...

We examine some aspects of modelling and control in modern telecommunication networks, in the light of their evolution toward a completely virtualised paradigm on top of a flexible physical infrastructure. The trade-off between performance indicators related to user satisfaction of services (e.g., in terms of perceived quality, delay and ease...

Today's networks and services undoubtedly require a high level of protection from cyber threats and attacks. State-of-the-art solutions that implement Machine Learning (ML) have shown to improve the accuracy and confidence in threat detection compared to previous approaches, making it suitable for detecting today's sophisticated attacks such as...
