Abstract:
1. A device comprising a controller hardware arranged to send update commands to a first network element so as to control the first network element to update first configuration data stored in a configuration table of the first network element according to changes of second configuration data stored in a configuration table of a second network element, wherein the controller hardware is arranged to send the update commands in response to a situation in which the changes are made to the second configuration data and the second network element operates according to the second configuration data as a part of a data transfer network and the first network element constitutes a backup network element for the second network element, so as to keep the first network element capable of replacing the second network element in the data transfer network, and wherein the update commands are arranged to control the first network element to write, prior to an event causing a need to activate the backup network element, hardware specific data of the second network element to the configuration table of the first network element so as to enable the first network element to emulate the second network element in the data transfer network.
