Improving quality of service (QoS) in Multi-Protocol Label switching module

Until now, in the traditional IP network, the data packets take systematically the shortest path between two nodes through a core network. However, this system presents a major inconvenience: all the traffic follows the shortest path to go from the source to the destination. So the clutter state in a part of the network will be problematic. Today the new technology MPLS-TE permits to share the data according to the available resources in networks to guarantee the quality of service. Therefore, every packet will on label to assure a strict control according to the associated ticket, and the portion of the traffic can be deviated to some paths according to the rules of the mechanism MPLS-TE and constraints required by the operator. In this article, we modify the MPLS module, we propose MPLS-M to increase the throughput and reduce the number of lost packets.
