Class 29: Routing, Continued

Held Wednesday, April 12, 2000

Overview

Today we conclude our discussion of routing by visiting some upper levels of the routing hierarchy. We also visit some AS protocols in more depth.

Notes

• Assignment 6 is now due.
• Assignment 7 is now ready.
• Assignment 8 is coming soon.
• A fun Internet RFC can be found at
• A few of you have asked how far we're going to get. There are a little more than four weeks left in the semester. We're going to try to do significant parts of chapters 5 (TCP), 6 (Congestion Control) and 9 (High-level Protocols) before the end of the semester.
• How many of you know what an AS is?
• It looks like the ETS Major test will be on Sunday, April 29th from 1-3pm. We're still debating, though.
