NO RATINGS
We've been aggregating data from smart devices in factories for 10 years.  Ethernet is the dominate protocol, but only for non-time critical (non-deterministic) uses.  The problem is always the protocol for information exchange (not talking about TCP/IP but at the app level), OPC tried to address it in a general way, XML gose a long way too, but none get rid of custom programming.  Until there is a generally accepted way of communicating INFORMATION (not just the bits and bytes) this will be a hard thing to get a grip on.  Not to mention most plant managers couldn't give a fig about the technology, SHIP PRODUCT!

Thanks for the out fo the box thinking though!

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
