"On the Rollout of Network Slicing in Carrier Networks: A Technology Radar", Jose Ordonez-Lucena, Pablo Ameigeiras, Luis M. Contreras, Jesus Folgueira, Diego R. Lopez, Sensors, 21 (23), 2021. DOI: 10.3390/s21238094

Network slicing is a powerful paradigm for network operators to support use cases with widely diverse requirements atop a common infrastructure. As 5G standards are completed, and commercial solutions mature, operators need to start thinking about how to integrate network slicing capabilities in their assets, so that customer-facing solutions can be made available in their portfolio. This integration is, however, not an easy task, due to the heterogeneity of assets that typically exist in carrier networks. In this regard, 5G commercial networks may consist of a number of domains, each with a different technological pace, and built out of products from multiple vendors, including legacy network devices and functions. These multi-technology, multi-vendor and brownfield features constitute a challenge for the operator, which is required to deploy and operate slices across all these domains in order to satisfy the end-to-end nature of the services hosted by these slices. In this context, the only realistic option for operators is to introduce slicing capabilities progressively, following a phased approach in their roll-out. The purpose of this paper is to precisely help designing this kind of plan, by means of a technology radar. The radar identifies a set of solutions enabling network slicing on the individual domains, and classifies these solutions into four rings, each corresponding to a different timeline: (i) as-is ring, covering today’s slicing solutions; (ii) deploy ring, corresponding to solutions available in the short term; (iii) test ring, considering medium-term solutions; and (iv) explore ring, with solutions expected in the long run. This classification is done based on the technical availability of the solutions, together with the foreseen market demands. The value of this radar lies in its ability to provide a complete view of the slicing landscape with one single snapshot, by linking solutions to information that operators may use for decision making in their individual go-to-market strategies.

This article introduces the key innovations of the 5Growth service platform to empower vertical industries with an AI-driven automated 5G end-to-end slicing solution that allows industries to achieve their service requirements. Specifically, we present multiple vertical pilots (Industry 4.0, transportation, and energy), identify the key 5G requirements to enable them, and analyze existing technical and functional gaps as compared to current solutions. Based on the identified gaps, we propose a set of innovations to address them with: (i) support of 3GPP-based RAN slices by introducing a RAN slicing model and providing automated RAN orchestration and control; (ii) an AI-driven closed-loop for automated service management with service level agreement assurance; and (iii) multi-domain solutions to expand service offerings by aggregating services and resources from different provider domains and also enable the integration of private 5G networks with public networks.

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.

"Harmonizing 3GPP and NFV Description Models: Providing Customized RAN Slices in 5G Networks", O. Adamuz-Hinojosa, P. Munoz, J. Ordonez-Lucena, J. J. Ramos-Munoz, J. M. Lopez-Soler, IEEE Vehicular Technology Magazine, 14 (4), pp. 64-75, 2019. DOI: 10.1109/MVT.2019.2936168

The standardization of radio access networks (RANs) in mobile networks has traditionally been led by the 3rd Generation Partnership Project (3GPP). However, the emergence of RAN slicing has introduced new aspects that fall outside the 3GPP scope. Among them, network virtualization enables the particularization of multiple behaviors over a common physical infrastructure. Using virtualized network functions (VNFs) that comprise customized radio functionalities, each virtualized RAN (i.e., RAN slice) could meet its specific requirements. Although the 3GPP specifies the description model to manage RAN slices, it can neither particularize the behavior of a RAN slice nor leverage the network function virtualization (NFV) descriptors to define how its VNFs can accommodate its spatial and temporal traffic demands. In this article, we propose a description model that harmonizes 3GPP and the European Telecommunication Standard Institute (ETSI)-NFV Group viewpoints to manage RAN slices. The proposed model enables the translation of RAN slice requirements into customized, virtualized radio functionalities defined through NFV descriptors. To clarify this proposal, we provide an example describing three RAN slices with disruptive requirements following our solution.

"Automated Network Service Scaling in NFV: Concepts, Mechanisms and Scaling Workflow", Oscar Adamuz-Hinojosa, Jose Ordonez-Lucena, Pablo Ameigeiras, Juan J. Ramos-Munoz, Diego Lopez, Jesus Folgueira, IEEE Communications Magazine, 56 (7), pp. 162-169, 2018. DOI: 10.1109/MCOM.2018.1701336

Next-generation systems are anticipated to be digital platforms supporting innovative services with rapidly changing traffic patterns. To cope with this dynamicity in a cost-efficient manner, operators need advanced service management capabilities such as those provided by NFV. NFV enables operators to scale network services with higher granularity and agility than today. To this end, automation is key. In search of this automation, ETSI has defined a reference NFV framework that makes use of model-driven templates called NSDs to operate network services. For the scaling operation, an NSD defines a discrete set of instantiation levels among which a network service instance can be resized throughout its life cycle. Thus, the design of these levels is key for ensuring effective scaling. In this article, we provide an overview of the automation of the network service scaling operation in NFV, addressing the options and boundaries introduced by ETSI normative specifications. We start by providing a description of the NSD structure, focusing on how instantiation levels are constructed. For illustrative purposes, we propose an NSD for a representative network service. This NSD includes different instantiation levels that enable different ways to automatically scale this network service. Then we show the different scaling procedures the NFV framework has available, and how it may automate their triggering. Finally, we propose an ETSI-compliant workflow to describe in detail a representative scaling procedure. This workflow clarifies the interactions and information exchanges between the functional blocks in the NFV framework when performing the scaling operation.

"The Creation Phase in Network Slicing: From a Service Order to an Operative Network Slice", J. Ordonez-Lucena, O. Adamuz-Hinojosa, P. Ameigeiras, P. Munoz, J. J. Ramos-Munoz, J. F. Chavarria, D. Lopez, "2018 European Conference on Networks and Communications (EuCNC)", pp. 1-36, 2018. DOI: 10.1109/EuCNC.2018.8443255

Network slicing is considered a key mechanism to serve the multitude of tenants (e.g. vertical industries) targeted by forthcoming 5G systems in a flexible and cost-efficient manner. In this paper, we present a SDN/NFV architecture with multi-tenancy support. This architecture enables a network slice provider to deploy network slice instances for multiple tenants on-the-fly, and simultaneously provision them with isolation guarantees. Following the Network Slice as-a-Service delivery model, a tenant may access a Service Catalog, selecting the slice that best fits its needs and ordering its deployment. This work provides a detailed view on the stages that a network slice provider must follow to deploy the ordered network slice instance, accommodating it into a multi-domain infrastructure, and putting it operative for tenant's consumption. These stages address critical issues identified in the literature, including (i) the mapping from high-level service requirements to network functions and infrastructure requirements, (ii) the admission control, and (iii) the specific information a network slice descriptor should have. With the proposed architecture and the recommended set of stages, network slice providers can deploy (and later operate) slice instances with great agility, flexibility, and full automation.
