Homework 3—TCP

Due: Monday, October 2, 2017 (beginning of class)

The purpose of this assignment is to give you a deeper understanding of the TCP protocol.

Please submit your answers on paper (preferably typed and formatted with LaTeX). The due date is the beginning of class on Monday, October 2, 2017.

All problems from the book are taken from Chapter 3.

1. Problem P3. Note that the problem is asking for the 1's complement of the 1's-complement sum. In other words, add things using the 1's-complement addition rules, and then invert the bits in the result (which in 1's complement is equivalent to negation).
2. Problem P15.
3. Problem P23.
4. Problem P28.
5. Problem P40. Note that “above” in the problem refers to Figure 3.58, below it.
6. Problem P46. (And note that the answer to P48c is nearly two hours!)
7. Problem P53.
8. How much time did you spend on this assignment?
