Abstract: 

Exogenous losses --which are produced outside the transmission control
system of a traffic source, {\em i.e.}, independently of that source's
behavior and its long-term fair share of network resource-- have
always been regarded as introducing undesirable "noise" that needs to
be filtered out or hidden from the end points. In the first part of
the talk we will show that they can be sometimes surprisingly
beneficial. The second part of the talk will focus on leveraging the
presence of exogenous losses in favor of the TCP connections. In
particular, we propose a Flow-Profiled Queue Management (FPQM), being
exogenous aware, will actively accounts for the the exogenous losses
to guarantee efficiency and fairness.
