1. Gerenciamento de políticas de qualidade de serviço com suporte à mobilidade
This work provides a means to ensure the quality of service offered to users independently of their location. To manage the user mobility, it is used the Mobile IPv4 (MIP) architecture, and the QoS methodology used is Differentiated Services (diffserv). The diffserv architecture requires the use o multiple devices that need to be configured properly, and one

2. Uma arquitetura baseada em políticas para o provimento de QoS utilizando princípios de Autonomic Computing / A policy-based architecture for QoS provisioning using autonomic computing principles
Sistemas corporativos modernos cada vez mais dependentes da rede e a integração de serviços entorno do modelo TCP/IP elevam a exigência de Qualidade de Serviço da infraestrutura de TI. Neste cenário, o dinamismo das redes atuais em conjunto com os novos requisitos de QoS exigem que a infra-estrutura de TI seja mais autônoma e confiável. Para tratar e

3. Proposta de arquitetura de medição e estimativa de tráfego em redes DIFFSERV
This work presents a framework for estimating the delay in networks that implements the Differentiated Services QoS methodology. The work considers the use of the Policy Based Network Management (PBNM) model to perform the collection of data from the core and border routers in a DiffServ domain. The architecture is based on the IETF (Internet Engineering Tas

4. Configuração dinâmica de classes DiffServ e provisão de QoS para aplicações multimídia / Dynamic configurations of the DiffServ classes and provision of QoS for multimedia aplications
O crescimento contínuo da Internet é resultado da convergência dos vários mercados de comunicação (p.ex., telefonia, entretenimento e transmissão de dados) que utilizam-se de sua infra-estrutura para oferecer serviços. A qualidade de serviço das aplicações é influenciada por esse crescimento e a maioria delas trabalha com mídias contínuas, como

5. Infra-estrutura de transcodificaÃÃo para distribuiÃÃo de Ãudio em uma Intranet adaptÃvel ao estado da rede
With the advent of Computer Networks and their popularization, principally in 80 and 90âs decades, the traditional, secure and reliable centralized architecture, represented by mainframes, was rapidily substituted by a descentralized architecture haracterized by tring to resolve old problems already resolved by the old architeture and facing new problems, d

6. Clock synchronization in computer networks with quality of service
The Network Time Protocol (NTP), a protocol that synchronizes clocks from networked computers, has nearly two decades of existence and is continuously evolving. Due to its robust treatment of phase and frequency, an algorithm that disciplines the local machine clock, implementations available for a great deal of platforms and operating systems, it became a �

7. 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

8. 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
