My general course groundrules are here. Exams will count for between 70% to 80% of your grade, with homework and programs making up the rest.

Here is the final exam study guide; solutions are included.

Here is the course survey. You have through Sunday night, May 2, to answer it.

The material divides naturally into three "tracks" that we will alternate between, at will. Here are the tracks:

• LAN basics
• IP and routing (chapters 3 and 4)
• TCP and congestion (chapters 5 and 6)

This looks like the traditional four-layer model (LAN/IP/transit/application), but we're not really abiding by any strict layering. Here is further information about what will be covered in each track:

LAN basics

IP and routing

TCP and congestion

The following classic paper has useful information about TCP/IP security: Security Problems in the TCP/IP Protocol Suite by Steve Bellovin.
