Performance management in avionics telecommunication using passive testing

In this paper, we extend our passive testing based avionics network management approach to serve for not only fault management but performance management as well. First, we introduce the concept of passive testing. Then, we introduce the CFSM model and the observer model with the required extensions to support performance management. We introduce the new fault model including performance flaws. The fault detection algorithm using passive testing is amended with the detection of performance flaws. We briefly describe the fault location procedure together with the newly developed technique for performance management. Then, we illustrate the effectiveness of our new technique through simulation of a practical protocol example, the network layer protocol for the Aeronautical Telecommunication Networks. Finally future extensions and potential trends are discussed.
