[e2e] TCP flow count estimation

[Jon Crowcroft]

here's a daft idea for xmas:

if tcp is sending instead of MSS, alternate packets of size
MSS-1, and size 1
(well payload size)
and every packet elicits an ack,
it can use path char style estimation of the bottleneck line rate

it can use equation basedestimation of the bottlenck avaialble
capacity

between these two, it can deriv an estimate of the number of other
tcps (wel module notknowing their RTTs)

this might be useful for somethig....

j.
oh, if every other packet elicits an ack, then you need to intersperse
the small/large alternation over  3 packets - simple tho

think of it like running 2 seperate tcp flows tho, one with MSS 1
bute, one with mtu-41 and estimators for both
