 Notes on Rapid Spanning Tree

e Rapid Spanning Tree Protocol (RSTP) is a standardized method (IEEE 802.802.1w/

IEEE 802.1d) that enables the use of Ethernet networks with redundant data paths. Ethernet

networks with redundant data paths form a meshed topology with impermissible loops.

Due to these loops, data packets can circulate endlessly within the network and can also be

duplicated. As a consequence, the network is usually overloaded because of circulating data

packets, and thus communication is interrupted. e meshed structure is then replaced by

a logical, deterministic path with a tree structure without loops using the Spanning Tree al-

gorithm. In the event of data path failure, some of the previously disconnected connections

are reconnected to ensure uninterrupted network operation.

e Rapid Reconguration Spanning Tree Protocol (RSTP) is a standardized method (IEEE

802.1w) that enables the use of Ethernet networks with redundant data paths and prevents

the long timer-controlled switch-over times of STP. Usually, the formal term “Rapid Recon-

guration Spanning Tree” is not used, rather just “Rapid Spanning Tree Protocol” (RSTP).
