Performance evaluation of a multimedia server for ATM networks

Multimedia applications will need high speed networks. When designing dedicated servers for these new applications, it is necessary to estimate their performance. The work presented is a common work between CCETT (Centre Commun d´Etudes de Telediffusion et de Telecommunications) and INT (Institut National des Telecommunications). It is a performance evaluation of a multimedia server, a device able to offer audiovisual sequences to several users simultaneously, through a high speed network (such as an ATM network). A queueing network model has been developed and results are analyzed. Many simulations allowed the optimization of the dimensioning and the implementation of the server, depending on several parameters. A prototype has been built
