- Abstract
- In case of safety-critical embedded systems, software must have high availability to provide non-stop and reliable service. Therefore, we want to measure the availability of our system. However, using past methods, it takes a long time to measure availability because of irregular occurrence of faults. In this paper, we present SYNCEYE, which is a kind of fast availability measurement tool. To get the availability in a short period, SYNCEYE only measures MTTR (or downtime) using a fault injector. And then, it just calculates the availability with the heuristic MTTF (or uptime) such as 13.89 hours for achieving 99.999% availability goal. It helps us to decide a direction of optimization of the embedded systems.
