American bandwidth: What data-usage trends can teach us about the future

Calculate the effective bandwidth for the following cases. For (a) and (b) assume there is a steady supply of data to send; for (c) simply calculate the average over 12 hours. (a) 10-Mbps Ethernet through three store-and-forward switches as in Exercise 18(b). Switches can send on one link while receiving on the other. (b) Same as (a) but with the sender having to wait for a 50-byte acknowledgment packet after sending each 5000 -bit data packet. (c) Overnight (12-hour) shipment of 100 compact dis
