Uma arquitetura de proxy com prioridades de serviços para chamadas remotas de procedimentos de tempo real

Abstract

During the last few years is possible to observ an significant increase of real time applications, , mainly of multimedia applications (e.g. video and voice streamming). Factors such as the popularization of broadband (e.g. XDSL) and wireless (e.g. 802.11 familiy and 802.15 pattern) networks, associated to the appearance of better devices and the increase of user s communications need, have contributed. Currently, with the appearance of new concepts of communications like home networks, it is possible to predict that real time applications will be part of user s daily. Anticipating a solution to that predict, this work proposes a proxy architecture with priorities of services for real time remote procedure calls, that uses the earlier amount of tra_c to predict the future occupation network, and choose the most appropriate policy to adapt the proxy to the environment future states.
