Third Essay (due Jan 20) - Set 28.11.11

This essay is to be about trying to define "network architecture".

This is a difficult task, and it may be easier to write an essay about what is not architecture. A specific system may give ideas that could change a 
network architecture. What is trickier is to see when there are papers that
really shift the paradigm (design pattern) fundamentally. 

To write this essay, I'd encourage you to pick any 2 papers we have discussed this term, and use them as working examples for what is and what is not architectural (as opposed to "just" engineering). See
http://www.cl.cam.ac.uk/teaching/1112/R02/papers/
for the list of what was presented by is all in class.

If you have any questions, please don't hesitate to e-mail me at any point
(including over the vacation) and I will try to answer. If you write a draft
of the essay and want feedback on it early, before giving it in, that is 
also fine.
