Ethernet Consortia Wants To Unlock a More Time-Sensitive Network (networkworld.com)
Does Ethernet need new features like "stream reservation" and time synchronization to make sure time-sensitive data isn't delayed on the network? coondoggie quotes Network World: The demand from Internet of Things, automotive networking and video applications are driving changes to Ethernet technology that will make it more time-sensitive. Key to those changes are a number of developing standards but also a push this week from the University of New Hampshire InterOperability Laboratory to set up three new industry specific Ethernet Time-Sensitive Networking consortiums -- Automotive Networking, Industrial Networking, and ProAV Networking aimed at developing deterministic performance within standard Ethernet for real-time, mission critical applications. "Standards-based precise time, guaranteed bandwidth, and guaranteed worst-case latency in a converged Ethernet network is a game-changer to many industries," said Bob Noseworthy, Chief Engineer, UNH-IOL.
The article also acknowledges the work of the Avnu Alliance, which is also trying to build an ecosystem of "low-latency, time-synchronized, highly reliable synchronized networked devices using open standards through certification."

Dear Internet of Things,
First, fix your damned security problems. Then we'll talk about your "demands".
Sincerely,
The rest of the internet
Irony: Agile development has too much intertia to be abandoned now.
Networks aren't deterministic, so any protocol has to handle lost and delayed frames anyway. There is very little benefit to the complexity of low level traffic management, compared to using a simpler design and just adding more bandwidth. The internet is a "dumb network, smart edge" design, and it left "smarter" network designs in the dust for a reason.
It's the wrong layer to do "stream reservations" or any such kind of prioritising. Ethernet is supposed to deliver bits and frames as-is, managing buffers or the order of packets belongs to a higher layer. Such a layering violation results in no end of bloat and complexity. Complexity = errors.
The creatures outside looked from Alt-Right to Antifa; but already it was impossible to say which was which.
"Consortia" is plural. So Consortia agrees with "want", not "wants".
Even worse, the original submission was correct, so you went out of your way to make it incorrect. That takes dedication to bad English.
The real "Libtards" are the Libertarians!
Ethernet works well if you have over-provisioning. It is simple, almost zero-configuration, robust and reliable. This really bad idea would destroy all these characteristics. Why some (really bad) engineers cannot stay the hell away from things that work well is beyond me.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.

In that case, they need their own dedicated network. The public internet cannot guarantee a packet gets from Point A to Point B, let alone gets there in a specified time. All this does is provide an excuse to throttle "less important traffic", i.e. any website that doesn't pay greedy ISPs for higher priority.

Jeez, and I was just clicking into this article to post a sarcastic remark that ethernet was finally coming full circle from beatng out ATM, to becoming ATM, just like IDE/ATA became SCSI and USB is becoming firewire. Now I find I've been totally out-bus-protocol-geeked. Thanks for the interesting read.
Someone had to do it.
If you need all that, use ATM. Ethernet is meant to be a low cost technology for the vast majority who don't need those features.
