Project
Introduction
I am doing my assignment on my Honors project, which is a program to visualize network data. So far, I have already created quite a bit of the program, although it is not finished.
Background
The goal of the project is to display network logs in a simple way so the people with little training can get an understanding of whats happening in the network. We want to help people both identify possible threats and better understand the normal flow of network usage. The network logs I am using come from a small network Bob Ward takes care of here in Christchurch, he has given us access to anonymized logs, I currently have just over one month of logs, which amount to a few hundred megabytes. Here is an example network packet log:
| Time | protocol | size | source ip | source port | destination ip | destination port | packet type |
|---|---|---|---|---|---|---|---|
| 1269687620.676725 | IP | 48 | 192.168.100.6 | 4212 | 192.168.83.37 | 9101 | TCP |
| 1269687625.489346 | IP | 48 | 192.168.100.6 | 4213 | 192.168.110.12 | 9100 | TCP |
| 1269687632.684662 | IP | 328 | 192.168.109.26 | 68 | 192.168.99.1 | 67 | UDP |
So basically the program needs to read data from the log files, parse the packet records, and present them to the user by why of the graph as desired.

UML Diagram
This UML class diagram on 16/7/10, it is the beginning state of the project. I will make changes to it an update this page as I go.
Description of Classes
Design Critique
As seen in the initial UML diagram, I have used poor naming style. User:LukeRobinson
Final Design
Design Improvements
The first improvement, a very minor one, is to rename classes so that they all start with uppercase letters.
