Computer Networks by Andrew S. Tanenbaum 4th edition chapter 6 Question 4
Suppose that the clock-driven scheme for generating initial sequence numbers is used with a 15-bit wide clock counter. The clock ticks once every 100 msec, and the max- imum packet lifetime is 60 sec. How often need ... place (a) in the worst case? (b) when the data consumes 240 sequence numbers/min? Thank you!

Computer Networks 5th edition by Tanenbaum chapter 4 question 4
A large population of ALOHA users manages to generate $50 \hspace{0.1cm} requests/sec$, including both originals and retransmissions. Time is slotted in units of $40 \hspace{0.1cm} msec$. What is the chance ... is the probability of exactly k collisions and then a success? What is the expected number of transmission attempts needed?
