Rapid Spanning Tree Protocol (RSTP)

Rapid Spanning Tree Protocol (RSTP) is a network protocol designed to prevent loops in Ethernet networks, ensuring reliable data flow. It quickly detects and disables redundant paths that could cause data collisions or broadcast storms, creating a loop-free topology. RSTP enhances traditional Spanning Tree Protocol (STP) by significantly reducing convergence times—how fast the network reorganizes after a change—leading to more efficient network stability. Essentially, RSTP maintains continuous, reliable communication across network switches by dynamically managing connections and preventing problematic loops.
