Reading Review for Class 5

This class’s readings are:

• Jain89 (Sections 2.2 - 2.5 and 4 optional)
• Dismantling a Religion

Optional:

• Starvation
• Contention

Your review should include both a summary of these papers, which discusses

• the problem the paper addresses
• the paper’s solution
• the evidence the paper provides that the solution was correct. Remember to keep in mind the historical context the papers discuss.

Your review should also discuss, after the summary:

• whether the problem the paper solved is an important one
• whether the solution was a good one
• whether the paper was fun or enjoyable to read.
• what questions you have about the paper, or which parts of the paper (if any) you found hard to understand.

You should answer the above questions in about one sentence each. The remainder of your review (about the below questions) should be about a page (~500 words) long.

Finally, for this week’s papers, please reflect on the following questions:

• What assumptions do Chiu and Jain make in their analysis of AIMD congestion control algorithms? Were these valid assumptions to make in 1989, and do these assumptions still hold today? For example, what would the interaction between a Private WAN network like B4 or SWAN and congestion control be?

• Does the Internet today provide flow-rate fairness? Does it provide cost-rate fairness? If yes to either or both of those, explain why. If no to both, explain what kind of bandwidth allocation the Internet does provide. Do you agree or disagree with Briscoe’s argument? Which Internet actors might agree or disagree with it, and what might their reasoning be?
