Abstract
Organizations make rules for their users in order to optimize network usage and network
administrators control the users’ network traffic flow over the link. To have full control on
activities occurring on network is essential for managing bandwidth utilization to achieve
expected service quality. Managing the network is also useful for detecting attacks from
malwares, intrusion, or any restricted applications accessing the network. Bandwidth is the most
important thing in networking which is the line where traffic data passes through. The larger the
bandwidth, the more network traffic flows in it.
This study presents approaches to determine bandwidth utilization by using network traffic
analysis. Monitoring traffic data helps to know the bandwidth capacity and to filter applications
that make the network crowded with traffic. The ingoing and outgoing traffic is analyzed using
solarwinds which is efficient for capturing data from continuous streams of network traffic and
convert those raw numbers into easy to interpret charts and tables that quantify exactly how the
corporate network is being used, by whom, and for what purpose. Continuously, it records
ingoing and outgoing traffic from the router, core switch and firewall devices then logs the data
to generate daily, weekly and monthly statistics.
This study shows an effective use of network bandwidth by using network traffic analysis from
three campuses of AAU and traffic data recorded from network devices at the university data
center which shows the current bandwidth usage of AAU. As the experiment result shows, the
bandwidth usage in the university needs to be managed to serve all the university community.
Based on network traffic analysis and SARG report, bandwidth optimization model is proposed
which considered bandwidth consumption in weekly and monthly within different campuses.
Therefore, the ICT office has to take a measure to effectively distribute network bandwidth to
campuses.
