Solution set.

Due date: Apr 23

Files to be submitted:
  Hw4.zip

Purpose:

Related Course Outcomes:

(6) Understand network protocols, RIP and OSPF, and the details of IPv4.

(7) Develop a software simulator simulating RIP, OSPF, forwarding and subnetting in IPv4.

(9) Use networking tools including telnet, ping, traceroute, bing, and Ethereal to evaluate simple network characteristics.

Specification:

For the written part of the homework do the following problems out of the book: Ch 5 #9, #18, #24, #41. Put these in the file Hw4.pdf which you include in Hw4.zip. Each group member who is turning in a Cisco Lab should also turn in their PDF in Hw4.zip

For the coding part of the assignment I want you to do problem #56 out of the text, concerning fowarding in an IP router. Your program should be in a file: Forwarding.java, which will be run from the command line with a statement like:

java Forwarding IP_Address Table_to_Use.txt

Here Table_to_Use.txt is a text file consisting of an IP address, subnet mask and outline to use, each seperated by a space. For example:

192.168.1.0 255.255.255.128 3

Your program should output the line to use, based on the IP address and the table.

For the last part of your homework, I want you to do problem #57 concerning traceroute and submit a summary of your experiements in traceroute.pdf, which you also include in Hw4.zip. You should also do some Google searches to find out about which AT&T address corresponds to the line the NSA supposedly listens to and determine if the government is listening to your traffic.
