Questionnaire guidelines:
Typically, you just have to spend an hour skimming through the first paper on
the list. Spend a few minutes thinking about the problem/approach/contributions
of the paper and then answer the questionnaire briefly. This is mainly testing
your ability to think critically about the problem at hand. A response of
around 100 words is fine, although longer responses are also welcome. 


Question: 
---------

Routing in Interconnection Networks

Equation-2 in the first paper quantifies energy per flit transmission:
E_flit = E_R . H  + E_wire . D

E_R = energy per router
H = number of hops
E_wire = wire transmission energy per unit length
D = Manhattan distance between source and destination

Can you suggest mechanisms (not mentioned in these papers) to reduce the
above values and hence, network energy. For example, techniques to reduce 
the energy of a router, techniques to reduce the number of hops, etc.
