Interface

The parallel redundancy protocol (PRP) makes redundant transmissions on two (bundled) interfaces. To use this, you select two interfaces which the device internally combines into one interface. The device duplicates outgoing packets so that the packets are transmitted on each of the two interfaces. On the receiving side, the device recognizes the duplicates and discards them. This leads to a reduced packet error rate and to lower latency on the bundled interface in comparison to transmission on a single interface.
