The Spanning Tree Protocol (STP) is a network protocol that guarantees that every bridged Ethernet local area network has a loop-free topology. Dr. Radia Perlman, a distinguished engineer at Sun Microsystems, invented STP . Dr. Perlman came up with a way for bridges to achieve Layer 2 routing utopia: redundant and loop-free service. Consider a spanning tree to be a tree that the bridge holds in memory for fault-tolerant and optimised data forwarding. In a nutshell, the spanning tree STP is a technique for preventing loops in an Ethernet network through blocking connections. If active links crash, blocked links may be reactivated. The conceptual centre of a spanning tree is the root bridge, which sees all network traffic. When the network switches, spanning tree recalculations are done automatically, however they trigger a brief network outage. Newer protocols, such as TRILL, avoid loops while maintaining connections operational that would otherwise be interrupted by STP.
