akamai yesterday - what in the world was that

Fri Feb 14 14:24:46 UTC 2020

All,
There has been some initial discussions about beyond 400G for Ethernet.  It would be interesting to better understand how often this problem is now occurring - because I would imagine the problem is only going to get worse as the "binary blob" blobs out, which will only stress networks more.

Regards

John

I must admit, I'm blissfully unaware of CDN commercials, but I'd have expected that if I give a CDN my binary 100G binary blob and six people download it, I'd be billed a different amount to if six million people download it - and similarly if that blob is 1G vs 100G.

I guess I'm asking if there's an underlying problem with the model here, or if it's just the details of the numbers that are "wrong" in encouraging / discouraging certain behaviou

Tim.
