It is usually infeasible to test distributed systems and protocols for dependability, fault-tolerance and performance in the real operation environment. This is attributed to the cost of setting up the hosting distributed environment and the difficulty of controlling such a dynamic environment. The factors are too many and are very dynamic. This paper presents the Wide Area Network Emulator for CORBA Applications: a general purpose software tool that emulates a distributed networked environment for CORBA middleware and applications and gives the user full control over the emulation environment in addition to the ability to inject network-related faults.
