Evaluation of Quality Service Voice over Internet Protocol in WiMAX Networks based on IP/MPLS Environment

A case study that allows the interconnection of a Wimax structure supported on a MPLS Core is proposed, in order to take advantage of the benefits that offers MPLS working together with traffic engineering, virtual private networks and with the Diffserv technique; using the network Opnet Simulator; and in this way to assess characteristics that offers the switching of labels to transmit voice and video when trying to implement prioritization and differentiation of flows in order to provide QoS IP. Finally, we compare the results found at MPLS against MPLS-TP, and GMPLS technologies, in order to establish which one is the most optimal for sending streams of data susceptible to delays. In this sense the distribution of the article initially establishes a framework that includes a description of the main technologies that provide QoS in data networks, to then describe the methodology used in carrying out the simulations, followed by the presentation and analysis of the results found, to finally present in a comparative table, the validation of the data found against other simulated standards at the same network infrastructure, including their respective conclusions.
