In this sense, researches have been developed and have usually been approached several of the problems that are pertinent to the processes that can be automated in the hospital environment. Considering that in the automation processes, an imperative factor is the communication, because the systems are usually distributed, the network for data transference becomes itself an important point in these processes. Because this network should be capable to provide the exchange of data and to guarantee the demands that are imposed by the automation process. In this context, this doctorate thesis proposed, specified, analyzed and validated the Multicycles Protocol for Hospital Automation (MP-HA), which is customized to assist the demands in these automation processes, seeking to guarantee the determinism in the communications and to optimize the factor of use of the mean of transmission / Os conceitos da automa??o industrial j? est?o a algum tempo sendo incorporados na ?rea m?dica, passando tamb?m a ser utilizados na automa??o hospitalar. Nesse sentido, v?rias pesquisas t?m sido desenvolvidas e geralmente tem abordado v?rios dos problemas que s?o pertinentes aos processos que podem ser automatizados no ambiente hospitalar. Considerando que, nos processos de automa??o, um fator imperativo ? a comunica??o, visto que os sistemas geralmente s?o distribu?dos, a rede para transfer?ncia de dados passa a ser um elemento fundamental desses processos, pois devem ser capazes de prover a troca de dados e garantir ?s exig?ncias impostas pelo processo de automa??o. ? nesse contexto, que a presente tese de doutorado prop?s, especificou, validou e analisou o PM-AH (Protocolo Multiciclos para Automa??o Hospitalar). O PM-AH ? customizado para atender as exig?ncias dos processos de monitoramento de pacientes (redes de controle) em ambientes hospitalares e visa garantir o determinismo nas comunica??es, otimizando o fator de utiliza??o do meio de transmiss?o

With rapid expansion of interest in multimedia and distributed computing applications across the Internet increases importance of optimized delivery of group traffic. According to current situation the best practice to achieve this goal is multicasting. This masters thesis summarizes multicasting methods and facts. Also it draws conclusions from practical application of presented information on commercial project.
