Module Assignments

For this module you are required to complete the following assignments:

• Chapter 10: exercises # 1 - 5

1. Does the U.S. government support the Internet? Explain.

2. Given an IP packet of size 540 bytes and a maximum packet size of 200 bytes, what are the IP Fragment Offsets and More flags for the appropriate packet fragments?

3. The Hop Limit field in IP version 6 is 8 bits long (the same size as the equivalent Time to Live field in IPv4). Since this hop count is decremented each time an IP datagram enters a router, what are the implications of such a small field size?

4. Suppose there is a small commercial retail building with essentially one room. On one side of the room is a real estate agency and on the other side of the room is a guy who sells tea. What is the relationship between this setup and the concept of IP addresses with TCP port numbers?

5. Somewhere in the middle of the United States are two Internet routers with routing tables that are all messed up. The two routers keep sending their packets back and forth to each other, nonstop. Will an error message ever be generated from this action? If so, who will generate the error message and what might it look like?
