| Abstract | Nowadays, the number of multimedia applications that requires Quality of Service (QoS) guarantees, increases exponentially. But the current Internet provides very poor QoS to these applications. The current Internet does not have any mechanism for quality control. Because it uses normal IP routing that treats all packets in the same way and chooses the shortest path for forwarding the packets. Hence, in a multi-link network where has many links available for packet routing, the shortest path will gets congestion easily while the other longer links are not utilized. Contrary to IP routing, MPLS can support QoS for multimedia applications because of its enhanced features to improve Traffic Engineering (TE). TE is improved in MPLS because MPLS suppo1is explicit routing. By using explicitly routed LSPs, all paths in MPLS can be utilized and conh·olled for sending packets. Thus explicit routing can optimise the utilization of network resources and enhance traffic-oriented perfomrnnce characteristics. In this research study, we implement a MPLS network simulation with several scenarios using different MPLS TE features based on CR-LDP (Constraint routing label distribution protocol). The simulation results shows that MPLS really supports TE and improve the QoS for real-time traffic on an IP network. The overall network performances of all scenarios using MPLS are better than that of nmmal IP routing. |
