Fault management using passive testing for mobile IPv6 networks

In this paper, we employ the communicating finite state machine (CFSM) model for networks to investigate fault management using passive testing. First, we introduce the concept of passive testing. Then, we introduce the CFSM model, the observer model and the fault model with necessary assumptions. We introduce the fault detection algorithm using passive testing. Then, we briefly present our new passive testing approach for fault location, fault identification, and fault coverage based on the CFSM model. We illustrate the effectiveness of our new technique through simulation of a practical protocol example, a 4-node mobile IPv6 network. Finally, conclusions and potential extensions are discussed.
