Abstract: The primary goals of Quality of Service (QoS) are bandwidth management, controlled jitter, latency and improved packet loss characteristics to provide satisfactory services for users. Shaping network optimization is crucial for the service provider. To implement the network QoS, optimizing the current network physical and logical architectures is among the best practice. In this work, an attempt has been made to investigate the end-to-end QoS parameters of EthioTelecom service level agreement (SLA) customers network by using differentiated service (DiffServ) model, to manage end-to-end traffic delay, jitter, and packet loss. The traffics are classified and marked depending on their priorities. The proposed network architecture has used weighted fair queueing for congestion management and weighted random early detection for congestion avoidance method. The eNSP and Wireshark have used been to design, demonstrate and evaluate the network architectures. When the results of the existing network are compared with the proposed network architecture that is designed using the DiffServ model; delay, jitter, and packet loss have decreased whereas the traffic utilization increased.
