PDSI-based Static Route Online Configuration Method for QualNet Simulator

Network simulation has been widely utilized to test the rationality and reliability of the network protocols and models before practical implementation. Among the testing and experiments, data transmission based on the static routing protocol is inevitable and a huge repetitive works of static routing pre-setting are needed, especially for the case of large scale networks. In this paper, together with programmable dynamic simulation interface (PDSI), a static route online configuration method for QualNet simulator has been proposed, which allows users to configure static routes through the graphical interface (GUI) during the simulation process. After receiving the online configuration messages, QualNet will parse them, and then update the routing tables according to the time labels as well as the routing parameters. Experiment results demonstrate that the proposed approach is effective and the static routes can be successfully added and removed during the simulations.
