Automating Software Validation Of A Gpon Network

This paper presents the automation of a Gigabit Passive Optical Network (GPON) embedded software validation, which improves the coverage of tests and eliminates faults that may compromise system availability. A fault injection (FI) campaign based on a state machine model was performed emulating physical faults that automatically break down the communication between GPON network devices. Consequently, new failures were disclosed even after one-and-a-half year period using conventional test techniques. © 2013 IEEE.59Arlat, J., Aguera, M., Amat, L., Crouzet, Y., Fabre, J.-C., Laprie, J.-C., Martins, E., Powell, D., Fault injection for dependability validation - A methodology and some applications (1990) IEEE Trans. on Sw Eng, 16 (2), pp. 166-182http://www.cpqd.com.br/en, CPqD Website.
