Abstract
The Distributed object computing is a paradigm that allows objects to be distributed across a heterogeneous network, and allows each of the components to interoperate as a unified whole. This paper compares the layered architectures of various platforms such as COM/DCOM, RMI, CORBA, SOAP supporting distributed computing. While the fundamental structure of each is similar, there are differences that can profoundly impact an application developer or the administrator of a distributed simulation exercise. This paper compares the features of these distributed technologies and provides a more desirable support for distributed computing, as compared to rest of the object or component technologies.
