Submission Guidelines

Implementation Requirements

1- You should submit a tar file that contains the source code for your implementation.

2- Like the previous programs, you should submit a tar file. The tar file should include:

1. Makefile that compiles your implementation. The executable file should be named "node"
2. Source code of your implementation.
3. The typescripts output of running your implementation. There should be one typescript per node (numbered typescript.1, ...) for the scenario given below.

Questions

1- What should I display?

There are two cases in which you are going to display information.
Case 1: Change of topology as a result of receiving a HELLO packet or LSP (Link State Packet)

Your code should display the information received in the following format:

Case 2: Change In Routing Table

2- How are you going to run my program?

1. First, I'll untar the submitted file. Please don't create any directories.

2- Then, copy network.parameters, and network.config to the current directory. The first file will contain my parameters as defined in the assignment handout. The second file will contain the network topology I am going to use to test your code. I am going to use different topologies to test different cases.
You have to make sure that your code reads these files from the current directory.

3- Type "make". The name of the executable file should be node.
   There is no partial credit if your code does not compile successfully with no errors.

4- Run your program by typing "node node-number" where node number represents the number of the current running node. For example:

3- How do I submit my project?
You make a tar archive and then call a certain program from my directory called submit. The exact path is

Finally to submit your program, type

There is only one filename which is the tar file.

4- How am I going to test your code?
Assume that your program has compiled with no errors and an executable file, node, has been successfully generated. Also assume that I am using the topology defined in network.config . Following is a simple scenario that I can use to test your code:
 

Receiving HELLO Packet from node fe90::0003
Link (fe90::0002, fe90::0003) is ON
Node fe90::0003 is ALIVE

Receiving HELLO_ACK Packet from node fe90::0004
Link (fe90::0003, fe90::0004) is ON
Node fe90::0004 is ALIVE

Receiving HELLO_ACK Packet from node fe90::0002
Link (fe90::0004, fe90::0002) is ON
Node fe90::0002 is ALIVE
Receiving HELLO_ACK Packet from node fe90::0003
Link (fe90::0004, fe90::0003) is ON
Node fe90::0003 is ALIVE

Receiving LSP from node fe90::0003
Link (fe90::0003, fe90::0004) is ON

Receiving LSP from node fe90::0004
Link (fe90::0004, fe90::0003) is ON

The order of displaying the above information is not important.

Receiving LSP from node fe90::0002
Link (fe90::0002, fe90::0003) is ON

Receiving LSP from node fe90::0003
Link (fe90::0003, fe90::0002) is ON

Receiving HELLO Packet from node fe90::0001
Node fe90::0001 is ALIVE

(Note: routing table is not displayed since it does not change)
 

Receiving HELLO_ACK Packet from node fe90::0002
Link (fe90::0001, fe90::0002) is ON
Node fe90::0002 is ALIVE

Receiving LSP from node fe90::0003
Link (fe90::0002, fe90::0003) is ON
Link (fe90::0002, fe90::0004) is ON
Node fe90::0003 is ALIVE
Node fe90::0004 is ALIVE

Receiving LSP from node fe90::0002
Node fe90::0001 is ALIVE

(Note: routing table is not displayed since it does not change)
 

Receiving LSP from node fe90::0002
Node fe90::0001 is ALIVE

(Note: routing table is not displayed since it does not change)
 

Receiving LSP from node fe90::0003
Link (fe90::0003, fe90::0002) is ON
Receiving LSP from node fe90::0004
Link (fe90::0004, fe90::0002) is ON

(Note: routing table is not displayed since it does not change)

The order of the above communications is not important.

Grading Guidelines:
These are only guidelines to give you a hint about what I am going to test in your code. The points may be redistributed later during grading the assignment.
