Abstract in Portuguese
Esta dissertação de mestrado apresenta a prototipação de uma arquitetura denominada ServidorWeb com Diferenciação de Serviços (SWDS). O trabalho também apresenta a proposta, implementação e a avaliação de desempenho de dois algoritmos de controle de admissão denominados Algoritmo de Negociação e Algoritmo de Reserva de Conexões. O objetivo principal deste trabalho é a avaliação de desempenho dos algoritmos de controle de admissão no protótipo do SWDS. Como resultados, verificou-se que a Classe de maior prioridade consegue atender mais requisições que a Classe de menor prioridade em todos as configurações de carga. Também pode-se observar que o algoritmo de reserva de conexões consegue se adaptar a todas as variações de cargas

Abstract in English
This masters dissertation presents the prototype of an architecture named SWDS. This work presents the proposal, implementation and performance evaluation of two admission control algorithms named negotiation algorithm and connection reserve algorithm. The aim of this work is to evaluate the performance of the control admission algorithms in the SWDS prototype. As a result, it could be seen the high priority Class met a higher number of requests than the low priority Class. Also it could be seen the connection reserve algorithm can adapt to all workloads variation
