Making Ethernet work in realtime
Ethernet wasn't designed to deliver the determinism required to handle real-time network traffic. But high-speed Ethernet, especially with switching, can deliver the necessary performance. Combine it with Internet protocol, and you have an architecture that may become the best choice for real-time network applications.
