Performance Study Of Mpls And Ds Techniques To Improve Qos Routing For Critical Applications On Ip Networks, Salim Alsharif, Mohammad Mehdi Shahsavari

Electrical Engineering and Computer Science Faculty Publications

This paper aims to analyze the QoS performance of two main technology mechanisms, Multi-Protocol Label Switching (MPLS) and Differentiated Services (DS). The introduction of both mechanisms to support throughput and delay sensitive real-time media traffic will have an impact on critical applications with respect to QoS and traffic engineering. MPLS is a traffic forwarding mechanism that allows traffic to use multiple paths and DS is a mechanism that provides for aggregate traffic to be classified and conditioned at the edge of the network routers. The two modeled techniques and their performance will be evaluated with respect to their end-to-end delay. …
