The formula for calculating the MTTR is: MTTR = Fault detection time + Board replacement time + System initialization time + Link recovery time + Route convergence time + Forwarding recovery time. The smaller the addends are, the smaller the MTTR is and the higher the device availability is.

MTTR (Mean Time to Repair) is the total time taken to repair a failure and restore a system to full functionality. Reducing the time taken for each component of the repair process decreases the overall MTTR, thereby increasing device availability.
