Implementação da tecnologia MPLS-TE avaliando seus benefícios no setor de telecomunicações

Abstract

This work proposes to apply Multiprotocol Label Switching (MPLS) technology in conjunction with traffic engineering in order to provide better performance for a service provider's WAN network, using tunnels to manipulate traffic in the best possible way. Four simulated scenarios were performed using the GNS3 software, showing common situations in service providers: point-to-point failure, link failure, node failure and congested link. MPLS-TE techniques, such as RSVP-TE and Fast Reroute, were applied in them, evaluating whether they were capable of solving the proposed problems and showing the provider's and client's view in a virtualized environment, through Oracle VirtualBox. To demonstrate the efficiency of the technology, the Wireshark tool was used, in which it was possible to collect and analyze network packets and compare them with other common protocols in service providers
