Abstract: The present disclosure discloses a method and apparatus for monitoring a link state between nodes. The method includes: determining, by a first node, whether to transmit a first diagnosis message to a second node based on a monitoring result of whether to receive message data transmitted by the second node for a first time duration; processing, by the second node, the received first diagnosis message and transmitting the processed second diagnosis message to a third node; processing, by the third node, the received second diagnosis message and transmitting the processed third diagnosis message to the second node; determining, by the second node, whether to transmit the third diagnosis message to the first node; and determining, by the first node, a link state between the first node and the second node based on a monitoring result of whether to receive the third diagnosis message for a second time duration.
