What is STP? IEEE 802.1D.
It is based on an algorithm that was invented by Radia Perlman.

a. The Spanning Tree Protocol is important for loop avoidance
to create loop free paths
b. By comparing the throughput transferred to the destinations,
RSTP is a change to the original STP introduced to decrease
the amount of time required to react to a link or bridge failure.
