> Either it can transmit all of the internet traffic, so it has sufficient bandwidth to theoretically mirror the whole internet traffic, or it can't. A time unit doesn't make sense here. It’s not a time unit. It’s a rate. The rate is twice the rate of traffic on the internet. Therefore it can transmit all the traffic on the internet. Ideas like traffic only make sense in the context of per-unit-time, because they’re fundamentally about a flow.
