A CORBA design pattern to build load balancing and fault tolerant telecommunication software

As a mature distributed object computing middleware, CORBA is being used more and more widely in many fields to build large scale distributed software system. In telecommunication system, load balance and fault tolerance are especially important because of strict requirements for high reliability and capacity. In former studies, load balance and fault tolerance are considered separately more often. This paper introduces a new CORBA design pattern, named GenericFactory pattern, and discusses how to combine load disturbance and fault tolerance effectively. Advantages of this pattern are pointed out.
