This research proposes the design and performance evaluation of a Campus Area Network (CAN) for the University of Zawia using OPNET Modeler Academic 14.5. The study focuses on the northern campus, which consists of seven colleges and administrative offices, aiming to enhance academic and administrative communication through efficient network design. The proposed network supports multiple services, including FTP, printing, VoIP, email, database applications, and HTTP under heavy traffic loads. The network performance was evaluated based on key Quality of Service (QoS) metrics, such as delay, throughput, traffic sent and received, response time, jitter, end-to-end packet delay, and queuing delay. The results indicate that the proposed CAN demonstrates satisfactory performance under heavy loads, with efficient handling of applications like HTTP, email, and printing. However, applications such as VoIP and FTP require further optimization to reduce delays and improve throughput. The study also highlights the scalability of the network, suggesting that the northern campus can be connected to the southern campus without significant performance degradation. Recommendations for future research include optimizing VoIP, FTP and database performance. With potential for future expansion and improvement through advanced technologies and optimized network management. Keywords: Campus Area Network, Quality of Service, Network Performance, Scalability, Traffic Management.
