Slicing 5G fronthaul networks using programmable switches

Proceedings of the 16th International Conference on emerging Networking EXperiments and Technologies, 2020
Slicing is a critical technology in 5G, as it allows operators to slice a physical network into multiple virtual networks, each dedicated to a different use case/Mobile Virtual Network Operator (MVNO) [2]. Network slicing enables network operators to deploy a tailored set of resources for specific use cases or MVNO.

Fiber-Wireless Fronthaul/Backhaul Network Architectures for 5G

2018 IEEE 23rd International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD), 2018
5G-PHOS R &D project aims at architecting and evaluating 5G broadband networks for dense, ultra-dense and hotspot area use cases by capitalizing on existing wireless and optical technologies, while migrating from CPRI -based towards integrated Fiber-Wireless (FiWi) fronthaul/backhaul supporting mmWave mMIMO communications.

Assessment of fixed mobile converged backhaul and fronthaul networks

2016 18th International Conference on Transparent Optical Networks (ICTON), 2016
To cope with the forecasted traffic increase in mobile networks small cell deployments are considered as a key enabler. Compared with Macro Sites (MS), Small Cells (SC) will be deployed on a larger scale and thus require a more cost effective transport connection than in today's CWDM backhaul networks.

Joint relay selection and beamforming for mmWave fronthauling network

2017 IEEE/CIC International Conference on Communications in China (ICCC), 2017
Millimeter-wave (mmWave) fronthaul for Cloud-RAN has been considered as a promising 5G technique to meet the surging demand for high data rate. However, the Non-line-of-sight (NLOS) transmission problem seriously impacts the reliability of fronthauling network, and may leads to the breakdown of network.

Delay analysis of fronthaul traffic in 5G transport networks

2017 IEEE 17th International Conference on Ubiquitous Wireless Broadband (ICUWB), 2017
Cloud Radio Access Network (C-RAN) architecture claims to reduce capital costs and facilitate the implementation of multi-site coordination mechanisms. This paper studies the delay constraints imposed by the Common Public Radio Interface (CPRI) protocol in ring-star topologies used by mobile operators.

Assessment of future backhaul and fronthaul networks for HetNet architectures

2015 17th International Conference on Transparent Optical Networks (ICTON), 2015
Mobile traffic is heavily increasing in the last years and a massive continuous growth is forecasted for the next decade. To cope with this significant traffic increase in mobile networks and the further evolving competitive market situation, operators are looking for solutions to increase the capacity of their mobile networks, while keeping the cost ...

Handling Delay in 5G Ethernet Mobile Fronthaul Networks

2018 European Conference on Networks and Communications (EuCNC), 2018
In this paper we discuss how to handle delay in 5G Ethernet mobile fronthaul networks. The reasons for the delay requirements, addressing both service and protocol specific requirements, are discussed together with prime carrier needs of scalability of networks and easy migration to new network solutions.

Low-Latency Routing Scheme for a Fronthaul Bridged Network

Journal of Optical Communications and Networking, 2017
A fronthaul bridged network has attracted attention as a means of efficiently constructing the centralized radio access network (C-RAN) architecture. If we change the functional split of C-RAN and employ timedivision duplex (TDD), the data rate in fronthaul will become variable, and the global synchronization of front-haul streams will occur.

Fronthaul integration and monitoring in 5G networks

Intégration et supervision des liens Fronthaul dans les réseaux 5G Le Cloud RAN a été préconisé pour la 5G. Cependant, sa mise en place rencontre des difficultés notamment sur l'intégration du fronthaul, ce dernier généralement basé sur l’interface CPRI représente le segment situé entre la Digital Unit et la Radio Unit.
