"From Ethernet to TSN: real-time communication a small step, a big industrial 4.0"
--Xena Networks.
- TSN demand for more and more!
Industrial Ethernet, Ethernet automotive, aircraft-related networks, more and more network applications require "low latency delivery," "controllable delay in delivery," "low jitter", "bandwidth guarantees" and "security."
- TSN vendor support more and more!
TSN standards are maturing, more and more manufacturers to come Follow domestic industrial Ethernet Alliance is getting hot, Alliance members broke 20K mark.
- TSN achieve really challenging!
TSN = + Ethernet industrial control, how the use of high-bandwidth Ethernet performance and avoid their weaknesses unreliable transport, to achieve "high-bandwidth" + "controlled low-latency" is indeed a great technical challenge.
- TSN network testing need to focus on the following points:
- Network forwarding performance test ( traffic scheduling and reliable delivery of low-latency, low jitter protection, preemptive multi-terminal resources ... )
- TSN Protocol Conformance Test
