Read "The Design Philosophy of the DARPA Internet Protocols" by David Clark. Skip Section 10.
Because networking is a new topic for many of you, we've put together a short guide to the very basics of networking. It should help de-mystify some of the vocabulary in the DARPA paper. Lecture 8 will also give you a nice overview, but you need not wait for that lecture before reading this paper.
We also recommend this guide (a bit longer, but still short), which goes into more detail than ours. It's from 2002, but the concepts still apply today.
If you are confused by any part of the DARPA paper, especially terminology, those two guides should be your first resources.
A bit of background on the paper itself:
The paper starts by introducing the goals of the Internet's architecture (Sections 1-3). It then dives into the details of some of these goals (Sections 4-7) before discussing implementation details and concluding.

Question for Recitation
Before you come to this recitation, write up (on paper) a brief answer to the following (really—we don't need more than a couple sentences for each question). If your TA has requested that you email your answer to them, you may do that instead, but it should still be handed in before your recitation begins.
Your answers to these questions should be in your own words, not direct quotations from the paper.
