In networking one of the most critical tasks is to supervise the traffic generated by the connected devices. It is even more important on a network with over a thousand of endpoints, mostly used by university students of a faculty of IT engineering.
There are many ways of network monitoring, however considering the sizeable traffic, the NetFlow generated by the dormitory's Cisco 6500 core switch brings the best solution. In my thesis I will process and store the traffic information gathered by that device. The collected and interpreted data will be displayed to provide relevant information for both the users and administrators of the network in a clean, easily perceptible form. As a rapidly growing need, the system must be able to handle IPv6 traffic. Apart from displaying traffic information, the system will be ready to enforce the currently applied rules of the dorm network.
The complete system is designed to perform in a real-life environment, since it will provide the monitoring tasks of the whole network. Therefore the outcome of my thesis has to be a fully functional solution, which is integrated in the existent topology. In the implemented service an easy-to-use Web-based user interface is included, which will provide different functionality for network administrators and regular users.
