Re: Usage based pricing is coming for good or ill

"As the network will work no different if it was working at 10% utilization or 90% utilization."

Untrue, unfortunately. In a packet-switching environment, average pingtimes goes up rapidly even before 60% utilization hits. By 90% utilization on what's essentially a hub system (cablemodem upload channel), packet loss starts occurring and everyone's connectivity becomes really poor.

For ADSL DSLAMs, they often have very small backhauls relative to the total bandwidth all the ADSL modems could pull if in use at once. There may be 300-500 modems connected sharing a 100 mbit/sec fiber backhaul.
