Network Architectures

This course is mainly based around reading papers and learning how to find the positive and negative (in that order) in those papers. There is a preliminary schedule of when you will be speaking. Student's speaking assignments are to give a 20-25 minute prepared talk on the paper. I am very happy to discuss paper assignments and talks beforehand.

Here's some jolly good advice on How to read a paper by Keshav from Waterloo, plus how to write a great paper and give a great talk about it by Simon Peyton-Jones, from Microsoft.

We'll go through these topics at roughly one per week. There are also guest lectures from experts on their topics.

One thing I'd like readers to bear in mind is that one can take an evolutionary approach to network architecture change, or one can try to be revolutionary. In discussing a given paper, try to see which approach it is taking and whether this supports or undermines the viability of the proposed idea - this notion originated with Constantine Dovrolis and Jenifer Rexford in this nice counterpoint discussion. An important evolutionary refinement is Punctuated Equilibrium: which may be how technology (including networks) evolve really.

A very interesting complex systems/systems bio/eco/evolutionary view on how layered architectures evolve is this paper on Architecture, constraints, and behavior by John C. Doyle & Marie Cseteb.

Forwarding/Addressing & IPv6 for Oct 8 to 10

Course Introduction and Lecture 1

This paper by Dave Clark of MIT is the starting point for all network architecture papers in form and content: The Design Philosophy of the DARPA Internet Protocols

For presentation & discussion on Oct 15 to 17

To contrast with unified view of network architecture, (which reuse the form, but have very different conclusions from the Clark Internet Architecture paper above), see these two papers

to contrast with "always on" view that IP takes.

Other tricks are also centered around using names and identifiers differently - the first is near term:
