I'm not aware of MSOs configuring their upstreams to attain rates for 9 and 27 Mbps for version 1 and 2, respectively. The numbers you quote are the theoretical max, not the deployed values.

Well, according to wikipedia DOCSIS 3.0 gives 108 megabit/s upstream as opposed to 27 and 9 megabit/s for v2 and v1 respectively. That's not what I would call revolution as I still guess hundreds if not thousands of subscribers share those 108 megabit/s, right? Yes, fourfold increase but ... that's still only factor 4.
expands it's offering (currently, you can get 50Mb/s down and 30Mb/sec up), etc. If things are really as fragile as some have been saying, then the bottlenecks will slowly make themselves apparent.
Upstream capacity will still be scarce on shared media as far as I can see. -- Mikael Abrahamsson email: swmike@swm.pp.se
