The news that Comcast, Time Warner, and AT&T are all considering capping use of their networks — so that “overuse” would trigger a charge — has prompted intense discussion of just why these network operators are moving in this direction. One camp suggests that these operators have to do something to manage congestion, and because any protocol-specific discrimination plan raises howls of protest from the Net Neutrality side of the fence adopting bit-usage discrimination schemes is inevitable. It’s the least-bad approach, following this view.
The Net Neutrality side, for its part, points out that (1) each of us will fall into the 5% of “over-users” at some point or another, (2) the operators want to make sure that they remain the chief sources of video content, rather than allowing internet access to video undermine their business plans, and (3) it seems odd to manage to scarcity rather than invest in improved access for everyone. It’s as if the operators would prefer to keep internet access expectations at 2003 levels. And if you really wanted to manage congestion you’d charge differently for usage at different times.
