A company has been monitoring the performance of its network routers over a 2-year period and observed the following outages: Year 1 experienced 4 outages, totaling 16 hours, and Year 2 experienced 2 outages, totaling 12 hours. Assuming the network was operational for a total of 17,520 hours across both years, what is the Mean Time Between Failures (MTBF) for the network routers?
To calculate MTBF, divide the total operational time by the total number of failures. The total operational time over the 2-year period is 17,520 hours, and there were 4+2=6 outages. Therefore, the MTBF is 17,520 hours / 6 outages = 2,920 hours. Accurate calculation of MTBF is essential for gauging the reliability of equipment and scheduling maintenance to minimize downtime.
