Internet Service Providers (ISPs) have been quick to blame problems with service quality on so-called “bandwidth hogs.” According to AT&T, the top 5% of their Digital Subscriber Line (DSL) subscribers use 46% of the consumed bandwidth, and the top 1% of subscribers use 21%. But it is unclear what these figures mean, and if congestion problems could even be caused by those who use the network the most. These figures would seem to be describing the bandwidth consumption totals at the end of some designated time period (day, week, month). If this is the case, then 5% of subscribers using 46% of bandwidth consumed is not necessarily cause for alarm.
Excessive bandwidth usage is only a problem when it degrades the quality of service for other users of the network.
