Abstract: A method is disclosed for providing a network bridge between a source and a receiving network of a communication network, wherein the network bridge includes two content-bridging nodes connected between the source and the receiving networks according to a redundancy schema defined in IEC62439-3. The method can include assigning a common source network node identifier to the two content-bridging nodes; receiving, by each of the two content-bridging nodes, network traffic within the source network; and forwarding, by each of the two content-bridging nodes using the source network identifier, the network traffic from the source to the receiving networks.
