Previous issue date: 2006-08-02 / New multimedia applications that use the Internet as a communication media are pressing for the development of new technologies, such as: MPLS (Multiprotocol Label Switching) and DiffServ. These technologies introduce new and powerful features to the Internet backbone, as the provision of QoS (Quality of Service) capabilities. However, to obtain a true end-to-end QoS, it is not enough to implement such technologies in the network core, it becomes indispensable to extend such improvements to the access networks, what is the aim of the several works presently under development. To contribute to this process, this Thesis presents the RSVP-SVC (Resource Reservation Protocol Switched Virtual Connection) that consists in an extension of RSVP-TE. The RSVP-SVC is presented herein as a mean to support a true end-to-end QoS, through the extension of MPLS scope. Thus, it is specified a Switched Virtual Connection (SVC) service to be used in the context of a MPLS User-to-Network Interface (MPLS UNI), that is able to efficiently establish and activate Label Switched Paths (LSP), starting from the access routers that satisfy the QoS requirements demanded by the applications. The RSVP-SVC was specified in Estelle, a Formal Description Technique (FDT) standardized by ISO. The edition, compilation, verification and simulation of RSVP-SVC were made by the EDT (Estelle Development Toolset) software. The benefits and most important issues to be considered when using the proposed protocol are also included / O protocolo proposto nesta Tese, denominado Resource Reservation Protocol Switched Virtual Connection (RSVP-SVC), que consiste numa extens?o do RSVP-TE, vai de encontro ao surgimento de novas aplica??es multim?dia, que usam a Internet como meio de interconex?o. Tais aplica??es pressionam pelo desenvolvimento de novas tecnologias, tais como: MPLS, DiffServ e RSVP-TE, que introduzem novas e eficientes caracter?sticas ao backbone Internet, proporcionando uma significativa diferen?a no que tange ? provis?o de QoS (Quality of Service). O presente trabalho leva em conta o fato de que para se conseguir uma QoS fim-a-fim verdadeira, n?o basta implementar tais tecnologias no n?cleo da rede, ? imprescind?vel, estender tais melhorias ?s redes de acesso e qui?? ?s redes locais. Nesse sentido, muitos trabalhos est?o atualmente em desenvolvimento. ? no intuito de contribuir com este processo que este trabalho apresenta a defini??o de uma UNI MPLS SVC atrav?s do RSVP-SVC. Essa extens?o d? ao RSVP-TE a capacidade de estabelecer t?neis LSP (Label Switched Path) a partir de conex?es discadas, ampliando portanto o escopo de utiliza??o do MPLS, levando-o at? ?s redes locais atrav?s das redes de acesso, e provendo tamb?m suporte a uma QoS fim-a-fim verdadeira. O RSVP-SVC foi especificado em Estelle, que ? uma linguagem de especifica??o formal padronizada pela ISO. A edi??o, compila??o, verifica??o e simula??o do RSVP-SVC foi feita atrav?s do programa EDT (Estelle Development Toolset). Ademais, tanto os benef?cios quanto ?s quest?es mais importantes a serem consideradas quando do uso deste protocolo s?o apresentados
