Operation Execution Groups: efficient operation processing in widely distributed object systems

Operation Execution Groups (OEGs) address the problem of efficient execution of a sequence of long-distance remote object invocations in widely distributed, cross-organizational systems. OEGs are designed to improve the performance of operation processing with respect to client response time, using distributed replication that can be implemented without significant impact on existing server configurations and server objects. We present the general pattern of our solution, and describe and discuss a CORBA-based OEG implementation.
