Which protocol is recognized for detecting loops in the network?

The Rapid Spanning Tree Protocol (RSTP) is specifically designed for loop detection and prevention in Ethernet networks. It is an evolution of the original Spanning Tree Protocol (STP) and enhances both convergence time and efficiency. RSTP operates by establishing a tree structure in the network, identifying the best paths for data transmission while blocking redundant paths that could potentially create loops.

Loop detection is crucial in ensuring that data packets do not circulate indefinitely in the network, which can lead to broadcast storms and network congestion. RSTP achieves this by continuously monitoring the network topology and dynamically adjusting to changes, such as the addition or removal of switches. This allows it to effectively prevent loops from forming while ensuring that network resources are used optimally.

In contrast, the other protocols listed serve different purposes. The Ethernet Frame Protocol pertains to the nature of the data packets themselves but does not address loop detection. The Link Aggregation Control Protocol is used for combining multiple physical links into a single logical link to increase bandwidth and redundancy, rather than for loop detection. Finally, the Network Time Protocol is focused on synchronizing clocks across devices in a network and does not involve any looping mechanisms.

Thus, the Rapid Spanning Tree Protocol is the correct answer, as it plays
