[e2e] packet-pair probe implementation

[Arnaud Legout]

Constantine,
may be you could also have a look at a paper I wrote with Ernst Biersack 
that is about
an application of PP in the context of multicast congestion control:

A. Legout, and E. W. Biersack. *PLM: Fast Convergence for Cumulative 
Layered Multicast Transmission Schemes*. In /Proceedings of ACM 
SIGMETRICS'2000/, Santa Clara, CA, USA, June 2000
http://www.eurecom.fr/~legout/Research/research.html

Even if it is not on the PP technique itself, it could be quite 
interesting to see how effective PP can be to support
a congestion control algorithm.

Of course, in a FQ network, PP gives the available bandwidth which is, 
in the context of congestion control,
more interesting than the bottleneck bandwidth available in FIFO networks.

However, as Vern Paxson pointed out, the PP technique is subject to a 
lot of noise in a real world. The PP technique in a real
FQ network will be subject to even more noise, as it depends highly on 
the exact implementation of the FQ scheduling policy.
