Previous issue date: 2006-11-30 / The Ethernet technology dominates the market of computer local networks. However, it was not been established as technology for industrial automation set, where the requirements demand determinism and real-time performance. Many solutions have been proposed to solve the problem of non-determinism, which are based mainly on TDMA (Time Division Multiple Access), Token Passing and Master-Slave. This work of research carries through measured of performance that allows to compare the behavior of the Ethernet nets when submitted with the transmissions of data on protocols UDP and RAW Ethernet, as well as, on three different types of Ethernet technologies. The objective is to identify to the alternative amongst the protocols and analyzed Ethernet technologies that offer to a more satisfactory support the nets of the industrial automation and distributed real-time application / A tecnologia Ethernet domina o mercado de redes locais de computadores.

Este trabalho de pesquisa realiza medidas de desempenho que permite comparar o comportamento das redes Ethernet quando submetidas ?s transmiss?es de dados sobre os protocolos UDP e RAW Ethernet, bem como, sobre tr?s tipos diferentes de tecnologias Ethernet. O objetivo ? identificar a alternativa dentre os protocolos e tecnologias Ethernet analisadas que oferecem um suporte mais satisfat?rio ?s redes da automa??o industrial, e aplica??es de tempo real distribu?das
