1. Classificação de tráfego online baseada em sub-fluxos / Online traffic classification based on sub-flows
A classificação baseada em sub-fluxos é um passo no sentido de cumprir os requisitos para a classificação online do tráfego de rede. Este trabalho descreve uma estratégia de classificação baseada em sub-fluxos, aplicada aos tráfegos TCP e UDP, que abre uma perspectiva para classificar todo o tráfego de um link. O trabalho proposto utiliza a decomp

2. Análise de desempenho no uso de pré-busca para distribuição de vídeo sobre redes P2P
Peer-to-Peer Video on Demand Systems have well stabilished its importance in recent years. Such consolidation is due to the high gains that may be archieved in terms savings in transmission bandwidth of the servers. In this work, we evaluate how this technology can enhance the gains for the transmission of continuous media over the Internet. To achieve this

3. Métrica para análise da qualidade de vídeo transmitido em redes sem fio / Metrics to analyze the quality of videos transmitted through wireless networks
The goal of this work is to propose a metric to analyze the quality of videos transmitted through wireless networks. A wireless network is a degenerative means to transmit data given its huge instability, which affects transmitted videos. The present proposal adds a technical network parameter, known as jitter, to clients opinion. For these studies a video w

4. Avaliação de desempenho do protocolo MIPv6 utilizando a rede de telecomunicação aeronáutica (ATN). / Evaluation of performance of protocol MIPv6 using the aeronautical telecommunicaton networking (ATN).
Currently the use of standard IPS (Internet Protocol Suite) in the ATN it comprehends the concepts of IP mobility, convergence in the air-to-ground communication and also ATN sub-nets in land. The ICAO (International Civil Aviation Organization) mentions the ATN/IPS, which is based on connections supported by TCP and UDP protocols in the transport layer and

5. Optimal active queue management for the differentiated services architeture on the Internet / Controladores otimos para gerenciamento ativo de filas na arquitetura de serviços diferenciados da Internet
The Assured Service of Differentiated Services Arehitecture (DiffServ) is currently used for providing throughput differentiation in the Internet. For this, traffic policing and active queue management (AQM) mechanisms must be used. In this dissertation, we use a non-rational approach to develop an optimal AQM controller. Its design considers both adaptative

6. Modelos de trafego para fluxos gerados pelo protocolo UDP / Traffic models for UDP streams
An important characteristic of the traffic generated by IP protocol is the existence of scaling, since it has great impact on the performance of traffic control mechanism. Therefore, it has been the focus of attention in many researches. The scaling nature of IP traffic has generated lots of controversy. At small time scales the traffic is very irregular and

7. Avaliação de desempenho de redes sem fio 802.11b
Wireless Local Area Networks (WLANs) have grown a lot with the popularity of the 802.11 standard. WLAN is different than network wired, it has some specific features from wireless technology and use parameters to configure that affect performance and interoperability. This assignrnent evaluate WLANs 802.11b, with Fat architectures and Thin architecture. It p

8. A PLATFORM OF TESTS WITH SERVICES DIFFERENTIATED FOR MODELING OF TRAFFIC OF VOICE ON IP: impact and performance analyses. / UMA PLATAFORMA DE TESTES COM SERVIÇOS DIFERENCIADOS PARA MODELAGEM DE TRÁFEGO DE VOZ SOBRE IP: análises de desempenho e de impacto
Este trabalho apresenta uma plataforma de testes (testbed) sem custos, construída num ambiente controlado composto por microcomputadores e softwares livres. Implementa-se, em tal plataforma, o modelo de serviço diferenciado (DiffServ), com encaminhamento expresso (PHB EF). Propõe-se, fundamentalmente, a partir da obtenção das principais métricas de QoS
