Abstract: A gateway for a computer network includes a programmable integrated circuit device, and a first port and a second port coupled to the programmable integrated circuit device. The programmable integrated circuit device is structured and configured to, responsive to a restoration of power to the gateway following a loss of power at the gateway, read configuration information stored by the gateway, and if indicated by the configuration information, forward first data traffic from the first port to the second port and forward second data traffic from second port to first port until the programmable integrated circuit device is configured to do otherwise.

Abstract: Methods, devices, and systems for facilitating communications using a parallel redundancy protocol (“PRP”) bridge device are described herein. A PRP bridge device, in one embodiment, includes a first data port in communication with a first network, and a second data port in communication with a second network. Upon receiving a data packet at the first data port, the PRP bridge device is structured to determine whether or not the data packet includes a PRP data tag. If so, then the data packet is discarded. If no PRP data tag is present within the data packet, and a value of an EtherType header of the data packet is one of the values that the PRP bridge is structured to accept, then the PRP bridge device is capable of sending, using the second data port, the data packet to the second network.
