Abstract

Technology presented in the paper [1] allows validation of software architecture before component upgrades. This paper presents a case study of applying this method to the upgrade of a wireless monitoring system. After the validation showed the feasibility for an on-line upgrade, an actual upgrade was carried out and proven to be successful. A wireless monitoring system collects network data to deduce voice quality of voice-over-IP (VoIP) and notifies wireless users of network failures. Voice networks traditionally operate with an availability of 99.999%. Software upgrade must be done on-line to maintain such a high availability. Our experimental results show that the outcome of the actual upgrade is consistent with the validation result of the method in paper [1]. Our method is effective in providing round-the-clock wireless network activities while upgrading network protocols or application software.
