1) on the second part of Chapter 5, and go through the slides for Chapter 5. Please explain, how TCP sets

the TimeOut value in the Original Algorithm, and in the improved Jacobson/Karels Algorithm. Write

down related formulas in each algorithm.

In the Original Algorithm:

In the Jacobson/Karels Algorithm:

2. Assume that we use a UDP-based protocol for a file service application, where a client sends an initial

file request, and the server answers with the first data packet if the file can be sent. Client and server then

continue with a stop-and-wait transmission mechanism. Describe a scenario by which a client might

request one file but get another; you may allow the client application to exit abruptly and be restarted

with the same port.
