QoS in the MPLS-DiffServ network

The service types deployed (streaming) as well as the difficulties inherited from IP protocol make networks are vulnerable in terms of QoS management. It is thus necessary to fulfill customers´ requirements with regard to the transmission of the data conveyed through network IP, which can occur only by setting up suitable protocols (MPLS and DiffServ). Moreover, MPLS architecture introduces advanced functionalities in terms of QoS management such as the resource sharing and the optimization of flow. We highlighted functionality MPLS and to study the various algorithms and concepts of QoS for management of the performance Policy. In this article, we into practice put the techniques of video transfer in streaming and ftp. One studies the progressive installation of policies of QoS; we will show via a demonstration the importance of the choice of MPLS-DiffServ solution.
