The correct answer is B. halving effect. The halving effect is a general rule in network design stating that adding a parallel path between two points roughly halves the probability of downtime caused by a single failure, thereby increasing resilience.
Question
Adding a parallel path between any two points in a network will increase resilience by removing a single point of failure however, it should also be measured how much adding this second link increases resilience by reducing potential downtime. Which general rule can be adopted in network designs to account for additional links?
Options
- Amean time between failure
- Bhalving effect
- Cmean time to repair
- Dtotal up time
