Re: [arch-d] ETSI launches new group on Non-IP Networking addressing 5G new services

[Henning Schulzrinne <[e-mail]>]

Since we're talking slides, I'll throw in my take:

http://www.cs.columbia.edu/~hgs/papers/2019/2019%20Internet40%20IIT-RTC.pdf

Every single failed network architecture has promised QoS by making bits
more expensive; every successful technology has lowered the total cost of
deployment and operations and making bits cheaper.
