14. SER OU NÃO SER INTERNAUTA? Os significados da internet a partir do seu uso para jovens graduandos em redes de computadores na cidade de Salvador
Aiming to understand the importance of becoming an internet user, "To be or not to be an internet user?" reflects on the meanings of internet for young people, who according to PNAD 2005 and the search for 2007 of the Management Committee of the Internet in Brazil (CGI . ph), are among the majority of internet users in Brazil. The use of this technology is a

15. Uma alternativa a inundação baseada em tabelas de dispersão para planos de controle de redes opticas / A hash table based flooding alternative for optical networks control plane
The transport layer structure of the Internet is moving towards a model of highspeed routers interconnected by intelligent optical core networks. A consensus has been reached on wavelength division multiplexing (WDM) as the way to increase the transmission capacity. However there are few proposals for distributed control planes under dynamic Quality of Servi

16. Gerenciamento ativo de filas para o protocolo "High Speed Transmission Control Protocol" em redes com produto banda-atraso elevado / Active queue management High Speed Transmission Control Protocol in high bandwidth-delay networks
The efficient utilization of bandwidth in high speed and large delay networks, called high bandwidth-delay product networks (BDP), has become a major challenge. This is due to adjustments of the Transmission Control Protocol (TCP). The High Speed TCP HSTCP): a TCP variant to high BDP networks, employs more aggressive adjustments, allowing scalable bandwidth

17. Estudo sobre sistema de detecção de intrusão por anomalias: uma abordagem utilizando redes neurais / Anomaly based intrusion detection system using neural networks
The probability of occurring attacks in computers networks, and as a consequence the emergence of traffic anomalies, increased with the complexity growth of computer networks. The identification, analysis, and treatment of these anomalies in the shortest time possible have become more important and an essential part in network management. The main goal of an

19. MODEL-DRIVEN RESOURCE MANAGEMENT: ADAPTABILITY AND INTEROPERABILITY ON END-TO-END QOS SUPPORT / GERENCIAMENTO DE RECURSOS DIRIGIDO POR MODELOS: ADAPTABILIDADE E INTEROPERABILIDADE NO SUPORTE A QOS FIM-A-FIM
The evolution of codification techniques for continuous media is making distributed multimedia applications even more popular. This kind of application has performance requirements that must be met in an end-to-end fashion, which can be achieved only if quality-of-service (QoS) provisioning mechanisms are applied on each participant subsystem. These mechanis

21. Modelo de gerenciamento para infra-estrutura de medições de desempenho em redes de computadores / Management model for measurement infrastructure in computer networks
A avaliação do comportamento das redes de computadores através de métricas de desempenho é útil para avaliação de protocolos, para o aperfeiçoamento de aplicações, na escolha de conteúdo, entre outros. A obtenção destas métricas, porém, continua sendo uma tarefa complexa porque na maioria das vezes não se tem instrumentos adequados para tal.

22. UM ARCABOUCO PARA APLICAÇÕES DE ACESSO A SERVIÇOS DE MONITORAMENTO MULTI-DOMÍNIO / A FRAMEWORK FOR ACCESS APPLICATIONS TO MULTI-DOMAIN MONITORING SERVICES
Network performance measurements that cross different administrative domains are difficult to be obtained, due to use policy issues, security, etc. For these reasons, some national networks started efforts to allow the access to these types of measures, among them the Internet2, Géant2 and RNP. Given these efforts, it was created a document that defined and
