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

Testing distributed systems and protocols for dependability, fault-tolerance and performance in the real target environment is not usually possible. This is attributed to the cost of setting up a hosting distributed environment and the difficulty of controlling such a dynamic environment. This paper presents a general purpose tool that emulates a distributed networked environment at the application level and gives the user full control over the emulation environment.
