Verfahren zum Aufbau eines schleifenfreien Pfades zur Übertragung von Datenpaketen in einem Ringnetz

摘要

Method for establishing a loop-free path for transfer of data packets within a circular network upon a failure within the circular network, wherein the circular network comprises at least three bridges and at least three connections, wherein each connection is between two bridges, wherein each bridge has for each connection an incoming and an outgoing port, characterised in that, the method comprises sending from at least one of the bridges adjacent to a connection which is failing to the other bridges of the circular network an instruction to de-block incoming and outgoing ports which are non-adjacent to the connection which is failing.
