Abstract:
This paper describe the improvement of traffic engineering in the Internet Protocol (IP) network. The need of this improvement is because the conventional IGP algorithms that controlled the traffic engineering in IP network seem to ineffectively to distribute the traffic flows which will lead to the congestion at some point in the network. While the other traffic flows are underutilized. In this paper, we proposed MPLS to solve the network congestion in the IP network, and also we review the drawback of conventional IGP algorithms in the IP network in order to provide a background for the network simulation, the traffic engineering concept and the MPLS algorithms concept in order to improve the traffic engineering. Then a proposed model network was designed for the network simulation. The network simulation is used to demonstrate how the MPLS with ER-LSP and CR-LDP algorithms have improve the traffic engineering in the IP network while reducing congestion and improve network utilization. Finally, an analysis of the simulation is provided to measure the improvement that achieved from the network simulation. The measurement parameter is in term of its bandwidth, throughput, queue size and packet losses in the network. These all measurement is an essential element to determine the traffic engineering performance in the IP network after the improvement has been done.
