The problem with "sucking
what they can" is actually quite simple: When a router
, packets are lost
. When packet
s beyond a certain percentage
network, performance for everyone
goes way down hill. It is much better
to cap everyone
's pipe at a lower (but still reasonable
) data rate so that packet loss does not ocurr.
If all connections were TCP/IP, packet loss would not be that big a problem; since a lot of people are using streaming protocols that use UDP these days, though, routers can become saturated very easily.
