How do multi-layer networks improve fault detection capabilities?

Multi-layer networks offer benefits in improving fault detection and minimizing downtime by providing redundancy and fault isolation at different levels. This means that if a fault occurs in one layer, the impact is localized and does not affect the entire network. Additionally, multi-layer networks allow for better monitoring and management of network resources, which can help in quickly identifying and resolving issues before they lead to downtime. The segregation of functions in different layers also contributes to more efficient troubleshooting and maintenance processes. Overall, multi-layer networks enhance fault tolerance, increase network reliability, and reduce the risk of extended downtime.
