Ericsson Technology Review: 5G-TSN integration meets networking requirements for industrial automation

220 vues

Publié le

Time-Sensitive Networking (TSN) is becoming the standard Ethernet-based technology for converged networks of Industry 4.0. Understanding the importance and relevance of TSN features, as well as the capabilities that allow 5G to achieve wireless deterministic and time-sensitive communication, is essential to industrial automation in the future.

The latest Ericsson Technology Review article explains how TSN is an enabler of Industry 4.0, and that together with 5G URLLC capabilities, the two key technologies can be combined and integrated to provide deterministic connectivity end to end. It also discusses TSN standards and the value of the TSN toolbox for next generation industrial automation networks.

  2. 2. ✱ 5G-TSN INTEGRATION FOR INDUSTRIAL AUTOMATION 2 ERICSSON TECHNOLOGY REVIEW ✱ AUGUST 27, 2019 The move toward smart manufacturing creates extra demands on networking technologies – namely ubiquitous and seamless connectivity while meeting the real-time requirements. Today, 5G is good for factories; nevertheless, its integration with Time-Sensitive Networking (TSN) would make smart factories fully connected and empower them to meet all key requirements on industrial communication technology. JÁNOS FARKAS, BALÁZS VARGA, GYÖRGY MIKLÓS, JOACHIM SACHS Industrial automation is one of the industry verticals that can benefit substantially from 5G, including, for example, increased flexibility, the reduction of cables and support of new use cases [1]. At the same time, factory automation is going through a transformation due to the fourth industrial revolution (also known as Industry 4.0), and this requires converged networks that support various types of traffic in a single network infrastructure. ■Asitstands,IEEE(InstituteofElectrical andElectronicsEngineers)802.1Time-Sensitive Networking(TSN)isbecomingthestandard Ethernet-basedtechnologyforconvergednetworks ofIndustry4.0.Itispossiblefor5GandTSNto coexistinafactorydeploymentandaddresstheir primaryrequirements,suchas5Gforflexibility andTSNforextremelylowlatency.Beyondthat, 5GandTSNcanbeintegratedtoprovidesolutions totheaforementioneddemandsofubiquitousand seamlessconnectivitywiththedeterministicQoS FOR INDUSTRIAL AUTOMATION 5G-TSNintegration meetsnetworking requirements
