Standardization of messaging topologies for communication in recent distributed object computing architectures is becoming more and more inevitable. The emergence of a structured and flexible document model as XML has made an entry point towards this goal. In this thesis, we are utilizing the flexibility of XML and the simplicity of low -level socket communication to build a generalized messaging model that provides a basis for standardization and supports interoperability among existing distributed object computing architectures. The proposed system is composed of the basic components of a distributed architecture constituting a number of broker components acting as naming services and client/server objects. All components share the same features of having built-in support for XML parsing and communicating with sockets. The proposed model is language independent, so we used heterogeneous programming languages to model various components and test its feasibility. The measurement of invocation time is used for testing to provide an overview of the performance and overhead incurred by the system. Different runs with different types of components using direct and broadcast addressing are tested on multi-node setups and invocation times are measured as round trips from the client’s request to the server’s response.
