Abstract

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 and the observer model with necessary assumptions and justification. We introduce the fault model and the fault detection
algorithm using passive testing. We present our new passive testing approach for fault location, fault identification, and fault coverage based on the CFSM model. Examples are given for each fault management function to illustrate our approach. Then, we illustrate the effectiveness of our new technique through simulation of a practical protocol example, a 4-node mobile Ipv6 network. Finally future extensions and potential trends are discussed. (Cross-referenced as UMIACS-TR-2001-15)
