Abstract:
1. A method of communicating between a first communication node at a first site and a second communication node at a second site, wherein the first communication node is adapted to receive a protection command as an input signal from a relay connected to the first node, the method comprising: sending, by the first communication node, a message including operational data over a communication channel to the second communication node, and monitoring a channel quality of the communication channel based on the message; sending continually, by the first communication node, data packets including operational data over a non-deterministic communication channel including a packet-switched network to the second communication node; verifying, by the second communication node, whether data packets with an expected type of payload are received; monitoring, by the second communication node and based on said data packets, the channel quality; and increasing, as soon as the input signal from the relay is received, a repetition rate of the continually sent data packets.
