No. of bitstreams: 1 Alberto Lotito.pdf: 2153365 bytes, checksum: 3433c9bb5371bcce62f119c4593fe360 (MD5) Previous issue date: 2007-12-05 / This work intends to perform end-to-end traffic engineering through simulations in broadband multiprotocol networks and evaluate used parameters. We ve proposed and tested parameters used by the network administrator to dimension the action of an algorithm for Traffic Engineering. We dedicated special attention to IP networks interconnected to MPLS networks. Through simulations, we ve addressed questions of performance optimization, evaluating the network packet losses and compare the results with packet loss in the traditional OSPF network achieving improvements of up to 50%. This work contributes with improvements in traffic performance for real world networks, developing practical application since the traditional IP networks up to the present MPLS networks and also for mixed technologies. / Este trabalho tem como objetivos realizar simula??es de engenharia de tr?fego fim a fim em redes que trabalham com protocolos distintos e avaliar par?metros usados. Propusemos e testamos par?metros que servem para que o operador da rede dimensione a atua??o de um algoritmo para engenharia de tr?fego. Demos especial aten??o ?s redes que trabalham com IP interconectando-se a redes MPLS. Executando diversas simula??es, trabalhamos quest?es de melhoria de desempenho por meio de avalia??o da perda de pacotes nas redes testadas comparando-se os resultados com as tradicionais redes com protocolo OSPF e chegando a melhoria de at? 50% se comparado com este. Este trabalho contribui com melhorias em engenharia de tr?fego em redes do mundo real, desenvolvendo aplica??o pr?tica desde as tradicionais redes IP at? as atuais redes MPLS e tamb?m em redes de tecnologias mistas.
