Right, got it.

That much seems obvious. But do you have any analytical models that can
actual predict the magnitude of the quality attenuation for a given
network, say? And if so, are they available somewhere?

Also, some of the documents linked to from your web site seems to allude
to a scheduling algorithm of some sort. Is that available in paper form
(or better, code!) anywhere?


Thanks for your answers, will also take a look at the paper you linked
in your other email. :)
