You can't shape to a model you can't develop, but if you're already established, with those 40 customers you can develop a bandwidth-distribution layout and rather simply predict trends.. If you are in a highly volatile market, which xDSL doesn't seem to be quite yet :), this would be impossible, but adding customers at a constant rate with no changing technology would imply a constant trend.. Of course, as soon as technology changes that is no longer valid :), but.. alter the model on a monthly basis? .. I wonder if RX and TX equalize at some point? If you have enough static [customers] machines connected to be transmitting data at a steady level? I'd be curious to see some numbers on that.. -greg > >> Nobody in their right mind would sell T1 to every customer and do 1000:1 > >> overcommit of their transit links without some kind of bandwidth shaping. > >> Since that shaping is part of the engineering plan, the marketroids will > >> have to find some way to come clean about it in the advertising glossies. > > > >We've got 40 T1 ADSL customers coming into a single 1.1Mb SMDS connection > > And I'll bet they're all at different speeds as well, both TX and RX. > It sounds like you have to play it by ear, that coming up with some > mathematical model is *almost* impossible. > > > Regards, > > -- > Martin Hannigan [email protected] > Director of Data Networks V:617.500.0108 > XCOM Technologies, INC.
