The paper states typical latency is 30ms

Thus we are limited to 15 ro= und trips per second.

I h= ave a 960Gbs =3D 120 GBs Internet connection

Assuming 1260 byte packets, that means 95238 packets a= second

So we must have an average of 3174 packets = unacknowledged at 30ms latency

Get latency down to 1ms and the number of = unacknowledged packets goes down to 100.

Is the motive for Edge (i.e., latency) diminishing since its first
concepts were formulated more than a decade ago?

A recent work to share on "Revisiting the Arguments for Edge Computing=
