Strategies for Migrating from DCE to CORBA

Communication software middleware and distributed services for next-generation applications must be reliable, flexible, reusable, and capable of providing the necessary quality of service to applications like multimedia and telecommunication systems running over high-speed networks. Requirements for reliability, flexibility, and reusability motivate the use of object-oriented middleware like the Common Object Request Broker Architecture (CORBA). This document provides an indepth analysis of DCE and CORBA in terms of their key similarities and differences. It evaluates the advantages of porting DCE applications to CORBA, and describes the key areas where the porting effort is most likely to face the hardest problems.
