A CORBA-based Middleware for an Adaptive Streaming Server

Abstract

A CORBA-based infrastructure for an adaptive multimedia server is introduced, enabling dynamic migration or replication of certain multimedia applications among a set of available server nodes. The requirements from both the server's and the middleware's point of view are discussed. A specification of a CORBA interface and a corresponding implementation is presented. Finally, as a proof of concept, measurements of the implementation are shown and discussed. The measurements show the importance of the related servers' distribution on the network.
