There is no new paper for this recitation. But be ready to refer back to the Ethernet paper from last week!

Question for Recitation

Before you come to this recitation, you'll turn in a brief answer to the following questions (really—we don't need more than a sentence or so for each question). Your TA will be in touch about exactly how to turn that in.

Your answers to these questions should be in your own words, not direct quotations from the paper.

  • What does the term "layering" mean in the context of networking?
  • Why do we use a layered model?
  • How do you imagine that layered model is reflected in actual packets?

As always, there are multiple correct answers for each of these questions. For the last question especially, make an educated guess! It's okay if you don't know how this actually works yet.
