Internet architecture is at odds with its use  curiouslee.
Flickr curiouslee. Flickr  The largest manmade structure is now
used much differently than was originally intended by its
designers. Of all Internet communication, only a fraction of
traffic is intended to be exchanged between specific network
elements anymore. Instead, the network should find the content
desired by end users.  In his doctoral dissertation for the
Department of Computer Science and Engineering in Aalto
University, Jarno Rajahalme argues that this contradiction is
due to the inability to evolve the network architecture to
better match its use. The present structure of the Internet is a
result of commercial activity and competition. Rajahalme affirms
that this should be taken into account when designing and
modelling alternative Internet architectures. "There is a
mismatch between the way the Internet functions and the ways in
which it is actually used," Rajahalme pinpoints one of the main
issues of Internet communication research. Info
