Modern campus networks supporting many applications (for both real-time and other services) sometime lack the capacity to guarantee Quality of Service (QoS) for voice, video, and other interactive applications due to unattainable bandwidth requirement and high end-to-end delay. In this paper, best-effort services model and differentiated services model defined in RFC 2474 were analyzed. Enhanced differentiated services model was developed to improve and achieve better reduction in packet end-to-end delay of interactive traffic for video conferencing and voice streaming in a Campus Area Network (CAN). The simulation results obtained from the three services models show that enhanced differentiated services model with mean packet end-to-end delay of 0.10481s has 26% delay reduction as compared with differentiated services model with mean packet end-toend delay of 0.10757s. The enhanced differentiated services model has 32% delay reduction as compared to the best-effort services model with mean packet end-to-end delay of 0.15417s.
