25. PLEX MPLS : analise, projeto e implementação de uma plataforma para experimentos com MPLS com suporte a QoS
Dados a banda de transmissão atualmente disponível, o protocolo (IP) utilizado para transmitir a maior parte de tráfego e a quantidade de tráfego e seus requisitos de aos, a Engenharia de Tráfego (TE, de Traffic Engineering) tomou-se um componente cada vez mais importante nas redes de comunicações. O padrão do IETF para enncaminhamento roteamento ent

26. Uma estrategia de roteamento OSPF adaptativo baseado em estimação de banda / An adaptive OSPF routing strategy based on bandwidth estimation
Internet increase and diversity demand "smart" tools that could make possible to routing protocols self-adapt to network current state (its topology and congestion situation). Smart tools, although, can result in great processing and communication overload. This work presents, besides a new adaptive OSPF routing strategy based on bandwidth estimations, a sim

27. Um estudo do desempenho dos protocolos iSCSI e Fibre Channel
Nowadays, most of the corporations face a growing demand for efficient methods to manipulate information. Applications are becoming more sophisticated with richer content and consequent there is the need for more storage and faster access to information. In the past, storage systems and computer networks were two independent entities, but due to the huge dem

28. Utilizando CCM no suporte a sessÃes cooperativas sÃncronas
The Computer Supported Cooperative Work (CSCW) is concerned with investigating how people cooperate to solve problems and how that cooperation can be supported using computer resources. Synchronous cooperative applications provide functionalities that allow synchronous interaction among members of a group, who may be in the same place or geographically separ

29. Protocolos para difusão confiavel de mensagens em grupos de comunicação
In a Distributed System, computers cooperate to provide a service. One of the features in such systems is the exchange of messages among theses computers using a communication network. Many distributed applications, like replicated databases, require frequent broadcasts to/from the servers of data. In this case, a useful abstraction is the Group Communicatio

30. SECURITY PROTOCOLS IN NETWORKS OF COMPUTERS / PROTOCOLOS DE SEGURANÇA EM REDES DE COMPUTADORES
This work analyses several algoritms of cryptography; among them, the DES (Data Encryption Standard), the public key algorithm RSA and the public key distribution algorithm DH of Diffie-Hellman. Three security protocols are then proposed for interactive and one-way communication in packet switched networks. The sirst protocol was proposed with the assumption

31. The Open System Interconnection as a building block in a health sciences information network.
The interconnection of integrated health sciences library systems with other health sciences computer systems to achieve information networks will require either custom linkages among specific devices or the adoption of standards that all systems support. The most appropriate standards appear to be those being developed under the Open System Interconnection

32. The MAClinical Workstation Project at Georgetown University.
The intent of the MAClinical Workstation Project is to develop computer workstations for medical students of the sort they will use in future medical practice. The idea is to instill information query habits in the daily clinical activities of these young physicians-in-training. The Georgetown University Medical Center Library spearheads the project in conju
