[e2e] TCP over IP over ATM

First of all, I'ld like to thank for the many papers I've been pointed
to. I'm still to read them in detail.
My objective is not to study TCP/ATM in great detail, however it's the
obvious analogy to wireless networks which is interesting.
Up to now, people tend to think all networks to be wired networks - with
The extremely strong assumption being so made is no more and no less
that a link's service time and a link's workload capacity remain more or
less constant as long as the packet size remains constant.
Either assumption, concerning the service time and concerning the
capacity, is wrong.
This is hardly admitted by anybody from the wireless community - in ATM
it is "don't care" because, at least to my knowledge, ATM fades out.
However, before I fail to convince the community of adverse effects of
link variations on TCP in mobile wireless networks again and again I
thought it useful to have a glance on a wired "analogy", where the
problems are basically pretty much the same.
Not because ATM were error prone. But because ATM, particularly with
ABR, may expose a behaviour similar to that of a mobile network with
error correction to upper layers.
Would you agree? Or would you contradict here?
