Description: A link failure is an event in which a network link becomes unavailable or fails to transmit data. This type of failure can occur at various layers of the network infrastructure, affecting both connectivity and overall network performance. Link failures can be caused by a variety of factors, including physical issues such as damaged cables, hardware failures in network devices, or even configuration problems. Detecting and managing these failures is crucial for maintaining the availability and reliability of network services. In a network environment, a link failure can result in packet loss, increased latency, and, in extreme cases, total disruption of communication between devices. To mitigate these issues, various redundancy techniques and recovery protocols are implemented to allow the network to adapt to failures and maintain service continuity. The ability of a network to handle link failures is a key indicator of its robustness and efficiency, and it is a fundamental aspect of modern network design, especially in critical environments where availability is essential.
