| Abstract | ||
| All the new emerging QoS architectures are motivated by the desire to improve the overall performance of an IP network. Differentiated Services (Diffserv) define a model for implementing scalable differentiation of QoS in the Internet. Multiprotocol Label Switching (MPLS) is a fast label-based switching technique that offers new QoS capabilities for large scale IP networks. When an MPLS network supports DiffServ, traffic flows can receive class-based network treatment that provides bases for QoS guarantees.The objective of this work is to study the influence of the QoS mechanism via DiffServ-MPLS on network parameters such as jitter, delay and throughput . The comprehensive study showed general improvement in the throughput, jitter and delay particularly of voice and video transmission when using DiffServ-aware MPLS network as compared to pure IP only or MPLS only. | ||
