assigning, to each monitoring point (MP), a unique sender MP ID and a unique receiver MP ID, each of the sender MP IDs uniquely
identifying a sender MP from which a corresponding MP receives valid monitoring messages, each of the receiver MP IDs uniquely
identifying a receiver MP to which the corresponding MP transmits a valid corresponding monitoring message;
transmitting monitoring messages in a unidirectional cycle of MPs, each of the monitoring messages including a sender MP ID
and a receiver MP ID; and
detecting defects in connectivity at each of the MPs based on the sender and receiver MP IDs in the monitoring message received
at the MP.
