| 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. Service is only likely to be degraded for other users during peak usage hours because that is when the most people are on the network. In order for a user to fall within the top 5% of bandwidth users for a given time period they would have to be downloading content all day, not just during heavy usage times. For example, lets assume we study two users on the network, lets call them Alice and Bob. Both are on the same service plan and network, which allow them 5mbps normally, but the network gets congested during peak hours (5pm - 11pm) allowing a user to use at most 2mbps. Alice gets online at 2 am and starts downloading large files, maxing out her internet connection until the ... |
