Time Sensitive Networks: How changes to standard Ethernet enable convergence with industrial IoT

2,114 views

Published on

Standard Ethernet continues to expand its range, functionality and applications with the IEEE open standard, Time Sensitive Networking (TSN). The capabilities of TSN provide the industrial community with the ability to use standard Ethernet to support highly reliable and precise synchronized networking for industrial control. The presentation provides an update on the roadmap for TSN and an explanation around ways in which TSN enables seamless convergence within control networks. TSN updates to standard Ethernet will meet industrial control and measurement applications' needs, and solve interoperability issues by incorporating new capabilities needed in distributed systems. This presentation was held at the Hannover Messe Industry 4.0 Forum by Intel's Neil Stroud and National Instruments' Erik van Hilten.
