Abstract:
The purpose of this project is to analyze the performance of the newly established network
infrastructure at SEECS, H-12 Campus. At SEECS, a whole new structure of wired and wireless
networks have been setup, and presently it is extremely necessary and important to measure
quantities like delay, throughput, link utilization, packet losses etc so that future improvements
can be easily made. This project, therefore, aims to simulate the current network of SEECS using
OPNET, analyze the results and give suggestions for improvement.
In this project, the wired and wireless parts of the network have been simulated together under
varied types of generated traffic ranging from HTTP, FTP, and SMTP to audio/video streaming
and conferencing. The traffic load has been designed to mimic the network usage behavior of a
typical user. Simulations have been conducted to gather statistics like utilization, throughput,
delays, packet loss, jitter etc followed by an analysis of gathered statistics. Finally, it has also
been explored how VLAN provisioning can give QoS improvements for different types of traffic.
About OPNET: OPNET (Optimized Network Engineering Tool) is a commercially available
network simulation tool that is the first choice of industry since it is easy to train on and a
powerful to simulate up to date network technologies. It allows choosing different load
intensity for each application type (e.g. heavy, light, etc.) and offers a way to predict the impact
of a hardware upgrade, a change in topology, an increase in traffic load or the use of a new
application, on the network.
