Mobile Transport and Computing Platform for 5G Verticals: resource abstraction and implementation

This paper has been presented at: 2018 IEEE Conference on Network Function Virtualization and Software Define Networks (IEEE NFV-SDN)The 5G-TRANSFORMER project aims at transforming today's mobile transport networks into an SDN/NFV-based platform, which offers slices tailored to the needs of vertical industries. The paper describes the 5G-TRANSFORMER resource management layer, namely MTP, and its main functionalities such as resource abstraction, resource information modeling and orchestration, and service instantiation. Then, it focuses on the ETSI-based interfaces exploited for the interaction between the control and management plane elements. Finally, the paper reports an MTP implementation including messages reporting resource abstraction.This work has been partially funded by the EU H2020 5G-TRANSFORMER Project (grant no. 761536)

Automating vertical services deployments over the 5GT platform

This article presents a system for 5G networks that makes it possible to meet the diverse needs of vertical industries simultaneously sharing the same physical infrastructure. Orchestration, network slicing, edge computing, and federation are key technologies enabling industry verticals to have their own virtual networks, which might require aggregating transport networking and computing fabric, from the edge up to the core and cloud. Three novel building blocks are defined to meet these challenges in an automated manner: a vertical slicer as the entry point to create services and request slices, a service orchestrator to manage the services and decide their placement and allocation of required resources, and a mobile transport and computing platform virtualizing infrastructure networking and computing resources in an integrated manner. An experimental evaluation of the developed system shows its feasibility and confirms some of the benefits expected

5G-TRANSFORMER: Slicing and Orchestrating Transport Networks for Industry Verticals

This article dives into the design of the next generation Mobile Transport Networks to simultaneously support the needs of various vertical industries with diverse range of networking and computing requirements. Network Slicing has emerged as the most promising approach to address this challenge by enabling per-slice management of virtualized resources. We aim to bring the Network Slicing paradigm into mobile transport networks by provisioning and managing slices tailored to the needs of different vertical industries, specifically: automotive, eHealth and media. Our technical approach is twofold: (i) enabling Vertical Industries to meet their service requirements within customized slices; and (ii) aggregating and federating transport networking and computing fabric, from the edge up to the core and cloud, to create and manage slices throughout a federated virtualized infrastructure. The main focus of the article is on major technical highlights of verticaloriented slicing mechanisms for 5G mobile networks.This work has been partially supported by the EU H2020 5GPPP 5G-TRANSFORMER project (Grant 761536

Business Case and Technology Analysis for 5G Low Latency Applications

A large number of new consumer and industrial applications are likely to change the classic operator's business models and provide a wide range of new markets to enter. This article analyses the most relevant 5G use cases that require ultra-low latency, from both technical and business perspectives. Low latency services pose challenging requirements to the network, and to fulfill them operators need to invest in costly changes in their network. In this sense, it is not clear whether such investments are going to be amortized with these new business models. In light of this, specific applications and requirements are described and the potential market benefits for operators are analysed. Conclusions show that operators have clear opportunities to add value and position themselves strongly with the increasing number of services to be provided by 5G.Comment: 18 pages, 5 figure

Network Slices for Vertical Industries

Network Slicing allows to simultaneously support the specific needs of vertical industries with a diverse range of networking and computing requirements. Network Functions Virtualization (NFV) has been defined to deploy multiple network services on a common infrastructure. We extend the NFV concept to vertical services, i.e. services implemented on top of network services and providing the applications of the verticals. We present a component of the 5G-Transformer system, named vertical slicer, which acts as the interface to verticals. The vertical slicer has two main functionalities: allowing verticals to define vertical services based on a set of service blueprints and arbitrating among several vertical services in case of resource shortage.This work has been partially funded by the EU H2020 5G-Transformer Project (grant no. 761536

5G-TRANSFORMER Service Orchestrator: design, implementation, and evaluation

European Conference on Networks and Communications (EuCNC 2019)5G networks will pose complex network management challenges due to the variety of vertical services they will need to serve and the diversity and heterogeneity of underlying infrastructure. The service orchestration functionality is fundamental to enable fulfilling the requirements of the different verticals while efficiently sharing the infrastructure resources. This paper details the 5G-TRANSFORMER service orchestrator implementation and operation. It also evaluates and profiles service creation time showing how the automation offered by the platform allows reducing it from hours to minutes. It also shows that the most time-consuming steps correspond to the deployment of the virtual network functions and post-deployment configuration, which consume one order of magnitude more time than the rest of steps (e.g., network creation, port creation).This work has been partially funded by the EC H2020 5G-TRANSFORMER Project (grant no. 761536) and grants TEC2017-88373-R (5G-REFINE) and 2017 SGR 1195

5G-PPP Software Network Working Group:Network Applications: Opening up 5G and beyond networks 5G-PPP projects analysis

As part of the 5G-PPP Initiative, the Software Network Working Group prepared this white paper to demystify the concept of the Network Applications. In fact, the Network Application ecosystem is more than the introduction of new vertical applications that have interaction capabilities. It refers to the need for a separate middleware layer to simplify the implementation and deployment of vertical systems on a large scale. Specifically, third parties or network operators can contribute to Network Applications, depending on the level of interaction and trust. Different implementations have been conducted by the different projects considering different API types and different level of trust between the verticals and the owner of 5G platforms. In this paper, the different approaches considered by the projects are summarized. By analysing them, it appears three options of interaction between the verticals and the 5G platform owner: - aaS Model: it is the model where the vertical application consumes the Network Applications as a service. The vertical application deployed in the vertical service provider domain. It connects with the 3GPP network systems (EPS, 5GS) in one or more PLMN operator domain. - Hybrid: it is the model where the vertical instantiates a part of its Vertical App in the operator domain like the EDGE. The other part remains in the vertical domain. A similar approach has been followed in TS 23.286 related to the deployment of V2X server. - Coupled/Delegated: it is the model where the vertical delegates its app to the operator. The Network Applications will be composed and managed by the operator. This approach is the one followed in the platforms like 5G-EVE. In addition, the paper brings an analysis of the different API type deployed. It appears that the abstraction from network APIs to service APIs is necessary to hide the telco complexity making APIs easy to consume for verticals with no telco expertise and to adress data privacy requirements
