Abstract
The primary goals of Quality of Service (QoS) are managed bandwidth, controlled jitter, minimized latency, and improved packet loss characteristics to provide satisfactory services for users. Shaping network optimization is crucial for the service provider, too. To implement QoS mechanisms optimizing the current network physical and logical architectures is among the best practices. In this paper, an attempt has been made to investigate the end-to-end QoS parameters of multiprotocol border gateway protocol multiprotocol label switching virtual private network (MP-BGP MPLS VPN) EthioTelecom service level agreement (SLA) customers. That is done using differentiated service (DiffServ) model to manage end-to-end traffic delay, jitter, and packet losses. The traffics are classified and marked depending on their priorities. The proposed network architecture has used weighted fair queueing (WFQ) for congestion management and weighted random early detection (WRED) for congestion avoidance. The Huawei’s Enterprise Network Simulation Platform (eNSP) and Wireshark are used to design, demonstrate and evaluate the network architectures. When the results of the existing network are compared with the proposed network architecture its delay, jitter, packet loss and traffic utilization have shown improvements.
