RESUMO

This work describe proposals for the implementation of quality of service (QoS) in VPN MPLS architecture, and their performance analysis based on simulations are presented. New systems are developed based on the VPN MPLS architecture, and it is being proposed an extension for the VPN MPLS architecture to construct a dynamic mapping of VPN clients priorities into service provider network through the insertion of priority field at vrf table and MP-BGP protocol modification. All these systems were specified using the SDL object-oriented formal language with the SDL TAU Suite tool (Telelogic, Sweden). This tool allows the simulation with MSC diagrams of the specified systems, and the validation of these systems by detecting and correcting logical and specification errors. The performance analysis of these proposals were realized through the Opnet Modeler simulator.
