A reliability estimation method for reconfigurable routing and switching software

Recent years, a large number of open routing software architectures have emerged, such as XORP, ForCES, Ryu in SDN, reconfigurable platform, and so on. All of these architectures are open and comprising of components. They use components as the smallest resources, through the support of different assembly and release, to construct the complex routing and switching system. This paper take reconfigurable routing platforms for example, proposes a reliability valuating method based on Petri net and Fokker-Plank equations. Through the theory, it can verify the software component robustness ahead of time. Experiments show that the reliability evaluating results are coincident. The method of this paper solved the function robustness testing and reliability estimation problems of asynchronous interacted software in the reconfigurable routing platform with components dynamic loading and unloading. The practical significance is to reduce the workload of the testing staff and provides guidance to the routing software design to a certain extent.
