TL;DR: An experimental study on deploying a network slicing solution for an NPN in health environments that aims to provide both performance isolation over WiFi networks and privacy isolating the service traffic over the NPN network backhaul on the way to the application server, thus providing data confidentiality.
Abstract: 5G networks are envisioned to provide high Quality of Service (QoS) for several use cases that differ on their network requirements and where they should be deployed. Some use cases are deployed in Public Land Mobile Network (PLMN) infrastructures that are managed by mobile network operators. However, for other use cases, devices connect to the services over private networks or Non-Public Network (NPN). The NPN deployment is mostly envisioned by companies that will benefit from Industry 4.0 and also eHealth to enhance QoS and network security. Network slicing is the 5G concept that comes to address the different service requirements over the same network. In this paper, we present an experimental study on deploying a network slicing solution for an NPN in health environments. This solution aims to provide both performance isolation over WiFi networks and privacy isolating the service traffic over the NPN network backhaul on the way to the application server, thus providing data confidentiality.

TL;DR: In this article, the authors proposed multiple multi-domain solutions to deploy private 5G networks for vertical industries across their local premises and interconnecting them with the public networks, which can support interactions at different layers among various stakeholders, allowing for distinct levels of service exposure and control.
Abstract: Private 5G networks have become a popular choice of various vertical industries to build dedicated and secure wireless networks in industry environments to deploy their services with enhanced service flexibility and device connectivity to foster industry digitalization. This article proposes multiple multi-domain solutions to deploy private 5G networks for vertical industries across their local premises and interconnecting them with the public networks . Such scenarios open up a new market segment for various stakeholders, and break the current operators’ business and service provisioning models. This, in turn, demands new interactions among the different stakeholders across their administrative domains. To this aim, three distinct levels of multi-domain solutions for deploying vertical’s 5G private networks are proposed in this work, which can support interactions at different layers among various stakeholders, allowing for distinct levels of service exposure and control. Building on a set of industry verticals (comprising Industry 4.0, Transportation and Energy ), different deployment models are analyzed and the proposed multi-domain solutions are applied. These solutions are implemented and validated through two proof-of-concept prototypes integrating a 5G private network platform ( 5Growth platform) with public ones. These solutions are being implemented in three vertical pilots conducted with real industry verticals. The obtained results demonstrated the feasibility of the proposed multi-domain solutions applied at the three layers of the system enabling various levels of interactions among the different stakeholders. The achieved end-to-end service instantiation time across multiple domains is in the range of minutes, where the delay impact caused by the resultant multi-domain interactions is considerably low. The proposed multi-domain approaches offer generic solutions and standard interfaces to support the different private network deployment models.

TL;DR: In this article, a solution for non-public networks (NPNs) in e-health environments is proposed, which maintains QoS and privacy requirements among slices and also proposes a blockchain mechanism to secure the NS management layer.
Abstract: The new 5G networks must face the challenge to fulfill multiple requirements in different use cases, applications and verticals. These networks are designed to provide strict Quality of Service (QoS) compliance independently of the network conditions in each use case. Some use cases are deployed in Public Land Mobile Network (PLMN), infrastructures that are managed by mobile network operators. However, for other use cases, devices are connected to services in private networks named Non-Public Networks (NPNs). Network slicing is the 5G concept that addresses the compliance of multiple services requirements on the same network by virtualizing the physical network infrastructure. Network Slices (NSs) are created to manage the different requirements above and to ensure coexistence between these different requirements. In this work, we avail from network slicing concept to create a solution for NPNs in e-health environments which maintains QoS and privacy requirements among slices. Moreover, we also propose a blockchain mechanism to secure the NS management layer. This mechanism ensures data integrity and reliability for the NSs settings. We validate our approach by demonstrating our comprehensive solution to secure e-health environments sensitive data and the management of the slices by the e-health environments. We deployed a Proof of Concept (PoC) using the 5G EmPOWER system and a public blockchain and we evaluate some performance metrics in different scenarios.

TL;DR: The diverse use cases and network requirements of network slicing, the pre-slicing era, considering RAN sharing as well as the end-to-end orchestration and management, encompassing the radio access, transport network and the core network are outlined.
Abstract: Network slicing has been identified as the backbone of the rapidly evolving 5G technology. However, as its consolidation and standardization progress, there are no literatures that comprehensively discuss its key principles, enablers, and research challenges. This paper elaborates network slicing from an end-to-end perspective detailing its historical heritage, principal concepts, enabling technologies and solutions as well as the current standardization efforts. In particular, it overviews the diverse use cases and network requirements of network slicing, the pre-slicing era, considering RAN sharing as well as the end-to-end orchestration and management, encompassing the radio access, transport network and the core network. This paper also provides details of specific slicing solutions for each part of the 5G system. Finally, this paper identifies a number of open research challenges and provides recommendations toward potential solutions.

TL;DR: This paper introduces a flexible, programmable, and open-source SDN platform for heterogeneous 5G RANs, building on an open protocol that abstracts the technology-dependent aspects of the radio access elements, allowing network programmers to deploy complex management tasks as policies on top of a programmable logically centralized controller.
Abstract: Software-defined networking (SDN) is making their way into the fifth generation of mobile communications. For example, 3GPP is embracing the concept of control-user plane separation (a cornerstone concept in SDN) in the 5G core and the radio access network (RAN). In this paper, we introduce a flexible, programmable, and open-source SDN platform for heterogeneous 5G RANs. The platform builds on an open protocol that abstracts the technology-dependent aspects of the radio access elements, allowing network programmers to deploy complex management tasks as policies on top of a programmable logically centralized controller. We implement the proposed solution as an extension to the 5G-EmPOWER platform and release the software stack (including the southbound protocol) under a permissive APACHE 2.0 license. Finally, the effectiveness of the platform is assessed through three reference use cases: 1) active network slicing; 2) mobility management; and 3) load-balancing.

TL;DR: An overview of 5G non-public networks, studying their applicability to the industry 4.0 ecosystem, and a comparative analysis of these options, assessing their feasibility according to different criteria, including technical, regulatory and business aspects.
Abstract: The on-going digital transformation is key to progress towards a new generation of more efficient, sustainable and connected industrial systems allowing the so-called factories of the future. This new generation, commonly referred to as industry 4.0, will be accompanied by a new wave of use cases that will allow companies from logistics and manufacturing sectors to increase flexibility, productivity and usability in the industrial processes executed within their factory premises. Unlike typical use cases from other vertical sectors (e.g. energy, media, smart cities), industry 4.0 use cases will bring very stringent requirements in terms of latency, reliability and high-accuracy positioning. The combination of 5G technology with enterprise network solutions becomes crucial to satisfy these requirements in indoor, private environments. In this context, the concept of 5G non-public networks has emerged. In this article we provide an overview of 5G non-public networks, studying their applicability to the industry 4.0 ecosystem. On the basis of the work (being) developed in 3GPP Rel-16 specifications, we identify a number of deployment options relevant for non-public networks, and discuss their integration with mobile network operators’ public networks. Finally, we provide a comparative analysis of these options, assessing their feasibility according to different criteria, including technical, regulatory and business aspects. The outcome of this analysis will help industry players interested in using non-public networks to decide which is the most appropriate deployment option for their use cases.

TL;DR: Lasagna is introduced, a novel end-to-end solution that enables flexible management of slices encompassing both the wired and the wireless segments of an Enterprise WLAN and can ensure both functional and performance isolation between the different slices and efficient radio resource utilization.
Abstract: Current 802.11-based WLANs are asked to support an ever increasing number of services and applications, each of them characterized by a diverse set of requirements in terms of bitrate, latency, and reliability. Network virtualization and programmability are two emerging trends that can support the realization of such a vision in a cost-effective fashion. In this paper we introduce Lasagna, a novel end-to-end solution that enables flexible management of slices encompassing both the wired and the wireless segments of an Enterprise WLAN. Lasagna allows flexible management of network slices to meet their respective service requirements. An experimental evaluation carried out over a real-world testbed shows that Lasagna can ensure both functional and performance isolation between the different slices and efficient radio resource utilization. We release the entire implementation including the controller and the datapath under a permissive license for academic use.
