First communication node reports this node to receive the link down fault to management node, after management node receives the reception link down fault message of this node that first communication node reports, whether normal by the heartbeat detection between management private communication this management node of channel check and first communication node, be checked through this management node and first communication node, after heartbeat detection between the second communication node is also normal, management node is determined the reception link down fault message of first communication node, first communication node itself does not break down, and to the reception link down fault message of user notification first communication node.
Embodiment four
In this embodiment, if first communication node itself breaks down, cause first communication node can't carry out any normal process, management node detects schematic diagram that first communication node breaks down itself as shown in Figure 5.In this case, the second communication node can detect and first communication node between heartbeat detection break down, the generation heartbeat is lost, also can not receive any announcement or data that first communication node sends over, and the second communication node does not detect its RX and breaks down, so the second communication node sends the fatal event announcement to first communication node, but first communication node can't be handled this fatal event announcement.
The second communication node to management node report and first communication node between heartbeat detection break down, can not receive any announcement or the data message that first communication node sends over.After management node receives the above-mentioned information that the second communication node reports, and it is whether normal by the heartbeat detection between the passage detection of management private communication and first communication node, because this moment, first communication node can't carry out any normal process, therefore, the heartbeat detection that detects between this management node and first communication node of management node is undesired.So management node judges that first communication node itself breaks down, management node itself breaks down to user notification first communication node.
