Abstract

DIMMA — A Distributed Interactive Multi-Media Architecture — is an open distributed processing (ODP) platform that facilitates the production of distributed applications. It has particular support for those applications that have soft real-time constraints, and those that make use of multi-media.

DIMMA consists of a portable layer of distribution engineering (middleware), together with tools to interface applications to this engineering. The most popular commercial ODP platform is the Common Object Request Broker Architecture (CORBA) whose definition is managed by the Object Management Group (OMG). In recognition of this popularity, DIMMA supports a CORBA compliant API so that CORBA applications may be easily ported to or from the DIMMA platform.

This paper describes the example implementation of DIMMA. It gives an overview of the motivations behind the design of DIMMA and then highlights some key features of the DIMMA implementation. It concludes with a brief analysis of DIMMA’s performance
