A Dependable Alternative to the Spanning Tree Protocol

The Spanning Tree Protocol (STP) is known to have stability problems and poor convergence intervals. Several protocols and variants exist targeting the replacement of STP variants, most of them proprietary and with limited scope of operation. The recent protocols, IETF TRILL and IEEE SPB, target mainly data center networks, are based on complex concepts, require great processing power from switches and huge investment in new gear.
