13. O impacto de controladores de banda em domÃnios diffServ e roteamento dinÃmico
Quality of Service (QoS) to TCP/IP networks is a technology that promises to improve applications by guarantying their reliability, in the biggest network of computers in the world, the Internet. Amongst the architectures to implement QoS, there is the Differentiated Service (DiffServ). An architecture based on the priorization of packets or services that de

14. AVALIAÇÃO DE DESEMPENHO DE FLUXOS TCP EM REDES DE SERVIÇOS DIFERENCIADOS / PERFORMANCE EVALUATION OF TCP FLOWS IN DIFFERENTIATED SERVICES NETWORKS
This work presents a Diffserv architecture study to provide QoS in the Internet. The emphasis of the study is on the performance of flows that use the TCP transport protocol. Initially, basic concepts, TCP characteristics in its different versions and the main mechanisms of traffic control are reviewed. A modeling of the Diffserv architecture, aiming at the

16. QoSPY an approach for QoS monitoring in diffserv networks.
Emerging applications with strict performance requirements have introduced needs for distinguishing services in computer networks so as to prioritize some applications more important or profitable than others. Actually it is possible to deliver only one service for all kinds of traffic so far, known as Best-effort service. Therefore, some Quality of Service
