Abstract

Since communication systems software is very large and complex, it requires component based architecture for software reusability, hardware transparency, high performance, and easy software reconstruction in different applications. In order to meet these requirements, we analyze performance and inter-process communication techniques of existing CORBA IIOP, and designed a shared memory-based CORBA inter-ORB protocol that would best fit for communication systems software. The designed protocol supports the same interface and can minimize the message transfer overhead in the same host environment. The test results of our protocol compared with other protocols show that the performance is increased by about 15%-200%. We are thus assumed that our protocol can be used in developing CORBA-based component software architecture for communication systems.
