Hot Swapping Protocol Implementations in the OPNET Modeler Development Environment (Paperback)

This research effort demonstrates hot swapping protocol implementations in OPNET via the building of a dependency injection testing framework. The thesis demonstrates the externalization (compiling as stand-alone code) of OPNET process models, and their inclusion into custom DLL's (Dynamically Linked Libraries). A framework then utilizes these process model DLL's, to specify, or "inject," process implementations post-compile time into an OPNET simulation. Two separate applications demonstrate this mechanism. The rst application is a toolkit that allows for the testing of multiple routing related protocols in various combinations without code re-compilation or scenario re-generation. The toolkit produced similar results as the same simulation generated manually with OPNET. The second application demonstrates the viability of a unit testing mechanism for the externalized process models. The unit testing mechanism was demonstrated by integrating with CxxTest and executing xUnit style test suits.
