13. Modeling and computing of equivalent bandwidth of multifractal flows / Modelagem e computação de banda passante equivalente de fluxos multifractais
Scaling in network traffic can be identified as the absence of a typical time scale at which traffic burstiness can be characterized. Internet Protocol (IP) traffic presents both scaling and long-range dependence. Moreover, at small time scales, IP traffic shows non-uniform scaling and high variability. Moreover, the marginal distribution of counting process

14. Uma metodologia para caracterizaÃÃo de trÃfego de vÃdio baseada nos momentos e primeira e segunda ordem
This thesis presents a new methodology for video traffic characterization. A set of states are defined by a classification algorithm based on the first and second order moments of the codified video sequences. Modulation processes and time series generation that possess statistics associated with the states, defined by the classification algorithm considered

15. Dimensionamento de enlaces em redes com integração de serviços
The subject of this work is the dimensioning of link capacity for networks with integrated services (e.g., voice, video and data). Different types of services demand distinct levels of QoS (Quality of Service) - such as delay, jitter and packet loss ratio - which must be provided by the network. In this sense, two methods for link capacity calculation are pr

16. Analysis of optic nets without commutation using the method of the random traffic equivalent. / Análise de redes ópticas sem comutação usando o método do tráfego aleatório equivalente.
O objetivo deste trabalho é utilizar o método do tráfego aleatório equivalente para analisar e dimensionar redes ópticas sem comutação para arquitetura de nível único. Uma modelagem analítica, baseada nesse método, que possibilita otimizar os parâmetros da rede considerando padrões mínimos de desempenho é descrita. A rede em estudo utiliza ape

17. Ambiente de simulação de redes a eventos discretos
This work presents Hydragyrum, a tool for the simulation, design and teaching of communication systems. Hydragyrum is an application that allows the development of new communication system element models. Hydragyrum has a modular structure composed of processing nucleus (Kernel), models and interfaces that allow easy model set extension. The communication sy

18. Otimização da operação de sistemas de distribuição de agua abastecidos por bombeamento e reservatorios de regularização
In the present work it was developed an optimization model to water distribution systems operation, supplied by multiple pump stations and multiple reservoirs regulation. The difficulties to reach an appropriate modelling and the excessive simplification of the models have been delaying the appearance of practical solutions more adapted to dimensioning and o

19. Dimensionamento de redes de sinalização por canal comum
The Common Channel Signaling Network (CCSN) plays a major role in the modern telecommunication network, which requires robustness and reliability features. This work presents a proposal for the dimensioning of the CCSN integrated to trunk network planning. Beginning with the trunk network, planned for a one year target, a top-down methodology that results in

20. Encaminhamento de chamadas telefonicas : analise de desempenho
This work presents a study about telephone networks routing plan assignment problems. Basically, two problems are studied: minimal cost routing plan assignment and optimal performance routing plan assignment. The junction network dimensioning problem is formulated as a multi-commodity minimal cost flux problem. The solution ofthis problem leads to a routing
