Spanning Tree Protocol, supported on most bridges and switches, is the tried and tested method for providing path redundancy while eliminating loops in bridged networks. Loops create never-ending data paths, resulting in excessive system overhead.
The key difference between STP and RSTP is the time it takes to converge. Once a link is lost or the topology has changed, STP requires 30 to 60 seconds to detect the changes and reconfigure, which affects network performance. When properly implemented, RSTP reduces the time it takes to reconfigure and restore service on link failures and restorations to sub-second levels, while retaining compatibility witequipment based on STP.
RSTP ensures rapid recovery of connectivity following the failure of a bridge/switch, bridge port or LAN. A new root port can transition rapidly to the forwarding port state. Explicit acknowledgements between bridges and switches in the LAN allow designated ports to transition rapidly to the forwarding port state.
