Abstract in Portuguese
Avanços nas tecnologias de comunicação e processamento de sinais além de mudar a forma de como realizar negócios em todo o mundo, têm motivado o surgimento de serviços e aplicações multimídia na Internet de forma crescente. Como conseqüência, é possível conceber, desenvolver, implantar e operar serviços de distribuição de vídeo digital na Internet, tanto na abordagem sob-demanda quanto ao vivo. Com o aumento das aplicações multimídia na rede, torna-se cada vez mais complexo e necessário definir um modelo eficiente que possa realizar o gerenciamento efetivo e integrado de todos os elementos e serviços que compõe um sistema computacional. Pensando assim, este trabalho propõe uma arquitetura de gerenciamento baseado em políticas aplicada à distribuição de conteúdo multimídia com controle de QoS (Quality of Service) em redes de sobreposição (overlay). A arquitetura é baseada nos padrões de gerenciamento por políticas definida pela IETF (Internet Engineering Task Force) que, através de informações contextuais (rede e clientes) administra os serviços disponíveis no sistema. Faz uso dos requisitos de QoS providos pela rede de distribuição e os compara com os requisitos mínimos exigidos pelos perfis das aplicações previamente mapeados em regras de políticas. Dessa forma é possível controlar e administrar os elementos e serviços do sistema, afim de melhor distribuir recursos aos usuários deste sistema.

Abstract in English
Advances in communication technologies and signal processing have not only changed the way business is conducted around the world, but have also driven the development of services and multimedia applications on the Internet. As a result, it is possible to design, develop, deploy and operate services for digital video distribution on the Internet, both according to an on-demand approach and live. Because of the increase in multimedia applications on the network, it has become increasingly more complex and necessary to define an efficient architecture that can achieve the effective and integrated management of all the elements and services that compose a computer system. With this in mind, this study proposes developing a robust and efficient architecture based on IETF (Internet Engineering Task Force) policy management standards applied to multimedia distribution content with QoS (Quality of Service) control in Overlay Networks. This architecture makes use of QoS requirements provided by the distribution network and compares them to the minimum requirements demanded by each type of application previously mapped in the policy rules. This system makes it possible to control and manage system information and services and also to distribute resources to system users better.
