Aplicación de la arquitectura Deffserv sobre redes MPLS para la provisión de QoS punto a punto en la transmisión de tráfico en tiempo real.

Abstract

This research aims to implement Architecture DIFFSERV on MPLS networks to provide traffic transmission point to point in the laboratories of the Cisco Networking Local Academy at the Polytechnic University of Chimborazo. Scientific and deductive methods were employed t o obtain the most important aspects of the implementation of the architecture DiffServ on MPLS networks. Experimental research and Descriptive were used for manipulation of the independent variable. The characteristic of the objet study also were analyzed . Observation techniques, evidence gathering and test environment on the laboratories of the Cisco Academy were applied. In each scenario the service quality indicators: delay, jitter and packet loss were evaluated. For the analysis, the D - IGT tool GUI 2.61 0.92 (Distributed Internet Traffic Generator) for IPT4, IPV6 traffic was used. This generated traffic at the network, transport and application level. After collection and tabulation of data it was found that the implementation of DiffServ over MPLS networks, reduced jitter for VoIP one 19.29% and 73.63% for data, one packet loss 85.34% 72.34% VoIP and data delay one 80.19 % and 73.39% for VoIP data in relation to IP networks. As conclusion, the architecture “Differentiated Services” on MPLS network s was appropriate because the measurements made in the parameters jitter, packet loss and delay thresholds were within the appropriate boundaries. A guide for implementing the DiffServ architecture for MPLS networks in the transmission of real - time traffic also was created. It is recommended that to ensure quality of service point to point , the MPLS backbone implementation with a model of Differentiated Services (DiffServ) must be used to ensure the quality of service.
