Topic Description
Projects Projects are individual coding efforts that comprise a majority of the class grade. They will involve the authoring of new code to resolve the questions set out in the project agenda.
Paper Writeups Each week there will be a set of papers to read focusing on either the history of networks or hot topics in the field. These will follow the last week's appropriate lecture content and hopefully be relevant and topical for industrial-minded students. The readings will also be discussed in class each week in group form. Each of the papers will require an associated writeup that demonstrates understanding of the content of the work. The writeup must detail:
  • A summary of the paper and its contribution.
  • A question you would like resolved in group discussion.
  • A critique of the work, be it methodological, theoretical, or other.
Paper Leads Each week 4 students (2 on the UW side, 2 on the MS side) will be paper leads. This means they will lead the paper discussion at their location. Sign-up sheet is here.


Note that homeworks and projects run concurrently and are due at 11:59 pm on the due date. Reading responses are due 11:59 two days before (Sunday).
