ABSTRACT:
A method for switching between a first network element and a second network element, the first and second network elements each connected to a first network and a second network. The method may be carried out by configuring the first network element and the second network element to recognize the same data from the second network. Next, data may be readdressed so that it may be recognized by both network elements. After readdressed data are sent to the first network element and the second network element, the first network element may be disconnected from the first network and the second network element may be connected to the first network. Data may be forwarded from the second network to the first network with little or no loss during the switchover.
