My 2 cents. I don't design these things, but you'd think people would start realizing that static allocation is kind of limiting. Giving someone 50mb/s with 20mb/s waste is annoying when they are saturating 3mb/s the opposite direction. Wouldn't it be cool if your backup at night could use 50mb/s upstream and drop your downstream to 5mb/s because you aren't downloading anything?
That's possible with multicarrier technology, such as xDSL. When you get into the data-over-cable technology, you find a completely different story -- it's a system limitation that you have an upstream channel that is less efficient than the downstream channel because the upstream channel has to be accessed by a number of sources, with access control, whereas the downstream channel is nothing more than a broadcast pipe (just like 10base-2 Ethernet) where you pick your packets out of the stream. Other technologies have their quirks, too...
