      Anyway, it would be great to have some average statistics on cable segment population etc. But you _know_ we'll never see that stuff! [grin] Too much competitive risk to telling us mortals that stuff. Even more interesting would be oversell of IP bandwidth of both cable and DSL.

      I suspect oversell in some cases to be more than 100:1 (For each 100 Mb/s DSL/Cable bandwidth to users, the ISP provides 1Mb/s) I think my ISP is better than that, but I woudn't be at all surprised to see some incredible oversell rates. Again, I don't know current Teir 1 T1 Rates (1.544) but I have heard it's around $1000 USD (I just did some research, and that seems about right...) Thus, to break even (not considering overhead and other costs) at $40/month of 256/256 DSL, you would have to sell 40 accounts. That's an oversell of 6.67:1. Since the DL cap for Cable is so much higher, I would expect much higher oversell rates - but they might not effect some users as much (they use during off peak hours etc)

      The truth?: DSL is shared bandwidth as much as any cable connection!

      This is how the dsl network works (ours, at least -- and everything in here counts only for the average 'residential' connection. no special cases like remote offices on dsl, etc..):

      dsl modem --[copper pair]--> dsl access multiplexer --[atm]--> broadband access server --[atm]--> isp ----> 'the internet'

      The dsl modem communicates at a speed of 1Mbit ( ok... i know that more is possible, but this is for accesses up to about 5km.) with the dsl multiplexer.
      One multiplexer takes 144 dsl line connections. All these connections are piped into one atm virtual path (vp), who has a bandwidth of 4 to 6 Mbit (here bandwidth is shared in a ratio of 36/1)
      Once the information arrives at the access server, authentification is done, and traffic is routed to the appropriate isp, over pvc's with a bandwidth of about 350Mbit/server for the largest isp. Without giving exact numbers, this amounts to about 23Kb/user.

      What all this means is this: you connection to the access server is not shared. Your actually bandwidth is.

The real issues are how many hops the connection has to take, and how much queuing occurs at each hop, e.g. how much time do your packets spend waiting for somebody else's packets, which depends a lot on the total bandwidth available vs. the bandwidth per individual subscriber.

    The Metricom Ricochet network had occasionally significant latency issues, because some radio poletops were directly connected to frame relay data feeds, while other poletops relayed data to each other until they reached a wired poletop, which incurred latency for queuing and copying and CPU processing at each poletop. So not only did you get affected by how many users were sharing a wired poletop directly or indirectly, but also by how far away you were from a wired poletop.
