Abstract

Verfahren, um Netzwerke wie Kommunikationsnetzwerke, insbesondere Ethernet Netzwerke, redundant und rückwirkungsfrei miteinander zu verbinden, wobei in dem zumindest ein, vorzugsweise mehrere Netzwerksegmente aufweisenden Netzwerk mehrere Netzwerkgeräte, die über Datenleitungen miteinander kommunizieren und Daten austauschen, vorhanden sind, dadurch gekennzeichnet, dass auf den Netzwerkgeräten zur Kopplung von Netzwerksegmenten zumindest mehr als eine RSTP-Protokollinstanz implementiert wird, so dass je RSTP-Protokollinstanz ein Netzwerksegment angebunden werden kann.
