Jacopo Cesareo will present his MSE talk on Monday May 7 at 11AM 
in Room 302 (note room!).  The members of his committee are:  
Jen Rexford, advisor and Michael Freedman, reader.  Everyone is 
invited to attend his talk.  His abstract follows below.

Traffic filters block clients from communicating with certain Internet 
destinations. To prevent clients from evading the filtering policies, 
traffic filters may also block access to well- known anonymizing 
proxies. In response, researchers have designed more sophisticated 
circumvention techniques that rely on implicit proxies, lying along the 
path to unfiltered destinations. An implicit proxy transparently 
deflects traffic directed to an unfiltered destination toward the 
filtered destination.
However, the effectiveness of implicit proxies highly depends on their 
presence in paths between clients and unfiltered destinations. In this 
paper we formulate and solve the problem of proxy placement, and 
evaluate our algorithms on snapshots of the Internet topology for a 
variety of client and destination sets. We also consider smart filtering 
techniques that select alternate routes to avoid implicit proxies, as 
well as the effects of asymmetric Internet routing. Our results show 
that a relatively small number of proxies can satisfy a large group of 
clients across a range of geographic locations.
