The design and implementation of a multi-threaded object request broker
Multi-threaded programming is a well-known technique for improving the performance of applications. In a CORBA environment, clients can invoke shared remote objects. If these objects are single-threaded, the performance of the system in the large distributed applications is affected. This paper presents a detailed description of the design and implementation of a multi-threaded Object Request Broker (ORB) on CORBA. The ORE was implemented on top of Windows NT and the underlying TCP protocol. The system's performance in both one-way and two-way requests is compared with that of a well-known commercial product, the IONA Orbix.
