A dynamic network simulator for testing TP monitor system performance and behavior

Network virtualization simulation tools had become very useful in the process of testing different new algorithms to which they are going to be applied in the distributed systems. In our recent experiments on benchmarking and analysis of an online Transaction Processing (TP) monitor system, we realize the necessity of using a network simulation tool in order to generate middle and large scale traffics to be able to test its reliability and failure tolerance. We must be able to produce series of signals, as well as some kinds of traffic with different and complex behaviors, failures and other random actions that could possibly occur in real situations. In this paper, we analyze some of the popular network virtualization tools in order to find the most suitable application for our ongoing research project.
