The present disclosure provides a fault detection method, a fault detection apparatus, an electronic device, and a machine-readable storage medium, so as to solve the problem that the number of users cannot be counted in a BRAS device.
The specific technical scheme is as follows.
In one embodiment, the present disclosure provides a fault detection method applied to a link node device, where the method includes: acquiring a sending plan of a detection message sent by opposite-end link node equipment to local link node equipment; comparing the actually received detection message with the sending plan, and if the actually received detection message does not accord with the sending plan, generating link fault information; and sending the link failure information to a main control unit for controlling the link node equipment.
Specifically, as shown in fig. 1, the method comprises the following steps:
step S11, obtaining a sending plan of the detection message sent by the opposite end link node device to the local link node device;
step S12, comparing the actually received detection message with the transmission plan, if not, generating link failure information;
step S13, sending the link failure information to a main control unit that controls the link node device.
And comparing the locally received detection message with the detection message which should be received, if the detection message meeting the conditions is not received, determining that the link reaching the local has a fault, and reporting fault information to the main control unit through a special channel so that the main control unit judges the link node with the fault according to the collected fault information.
When a certain link fails, the link node devices of the whole link behind the link cannot normally receive the detection message, and then report the failure information to the main control unit through the dedicated channel, the main control unit analyzes which link node devices report the failure information and which link node devices do not report the failure information according to the collected failure information, and meanwhile, the position where the failure occurs can be accurately obtained by combining the number of the failure information, and information is provided for maintenance and positioning.
In an embodiment, the sending plan of the detection packet sent by the peer link node device to the local includes: and the opposite-end link node equipment connected with the local link node equipment sends the detection message according to a preset rule.
For example, the detection message is sent according to a set periodic frequency, so that the local link node device can accurately analyze the receiving condition of the detection message.
In one embodiment, the comparing the actually received detection packet with the transmission plan, and if the actually received detection packet does not meet the transmission plan, generating link failure information includes: acquiring the number threshold of the detection messages which should be received in each period in the latest N statistical periods according to the sending plan; acquiring the number of detection messages actually received in each period in the latest N statistical periods; and if the number of the detection messages actually received in M statistical periods is smaller than the corresponding threshold value of the number of the detection messages which should be received in the latest N statistical periods, determining that the actually received detection messages do not accord with the sending plan.
In order to reduce the false alarm situation, whether the local link node equipment should report the fault information is judged in a window dividing mode. Illustratively, for example, 1 second is taken as a statistical period, N is taken as 6, in the last 6 periods, M is taken as 6, and the threshold value is taken as 1, and if no detection packet is received in any of the 6 periods, it is considered that the local link node device should report the fault information, in other embodiments, M, N, the threshold value, and the statistical period may all be selected as appropriate values according to actual needs.
In one embodiment, the comparing the actually received detection packet with the transmission plan, and if the actually received detection packet does not meet the transmission plan, generating link failure information includes: generating link failure information including source node information and destination node information; the source node information comprises source node slot position information and/or source node chip information and/or source node port information; the source node information comprises destination node slot position information and/or destination node chip information and/or destination node port information.
For example, the service detection packet is forwarded from the CPU0 to the LC0 to the SFC0 to the LC1 Fabric to the LC1 Chip0 to the CPU1 according to the following link path, where the CPU0 and the CPU1 are CPUs at both ends of the link, and are respectively a source CPU and a destination CPU, the SFC0 is a network board, i.e., a packet switching board, and the LC0, the LC1 Fabric, and the LC1 Chip0 are respectively a line card board and an associated Chip or node.
According to the prior art scheme, after the message is discarded on the link, the CPU1 only detects that the whole link is not through, and does not know which segment the message is discarded.
In this embodiment, the format of the message sent by the CPU0 is as shown in table 1, where unicast forwarding is performed based on the destination device in the switching network header field when forwarding is performed on each chip. E.g., to LC1 Chip0, the destination device is DEVID 1.
DMAC is a target MAC address, SMAC is a source MAC address, Ether type is a message type, Srcslot is source node slot position information, Srcchip is source node chip information, SrcPort is source node port information, Dstslot is target node slot position information, Dstchip is target node chip information, and DstPort is target node port information.
TABLE 1
If the SFC0 forwarding chip receives the message, judging whether the Ether type in the message is 0xdeff, if not, processing the message as normal. If the message is the service detection message, the Srcslot, Srcchip and SrcPort in the message are taken, 2 forwarding chips and 24 ports of each chip are taken as examples for calculation, and the value is adjusted according to the actual application environment. ((Srcslot. sup.2) + Srcchip. sup.24) + SrcPort acquires the offset address addr of the counter watchdog. And accumulating the watchdog counter corresponding to the addr. Thus, the monitoring and recording of the locally received detection message are completed.
The watchdog counter sets Event Threshold and Min Threshold, the change number of the scanned messages in each period is compared with the Event Threshold, if the change number of the messages is not less than the Event Threshold, the period is considered to be a normal period, otherwise, the period is considered to be an abnormal period, the number of abnormal periods in N periods is counted, if the number of the abnormal periods is more than or equal to the Min Threshold, interruption is triggered and fault information is reported, and an address value addr corresponding to the watchdog is reported, so that the main control unit receiving the fault information knows the position of the detected message which is not normally received.
If the sections from LC0 to SFC0 are not passed, the reported fault information comprises the slot number and the chip number corresponding to LC0 and the slot number and the chip number corresponding to SFC 0.
If the segment from SFC0 to LC1 Fabric is not passed, the reported fault information comprises the slot number and the chip number corresponding to the SFC0 and the slot number and the chip number corresponding to the LC1 Fabric.
If the section from LC1 Fabric to LC1 Chip0 is not passed, the reported fault information includes the slot number and the Chip number corresponding to LC1 Fabric, and the slot number and the Chip number corresponding to LC1 Chip 0.
In this way, the whole path through which the detection message passes can be acquired, but the whole path is not reported, and only the information of the local link node equipment and the opposite end link node equipment related to the fault part is reported.
The main control unit is used for comprehensively analyzing:
if the gathered information is that LC0 to SFC0 to LC1 Fabric to LC1 Chip0 and LC0 to SFC0 are not communicated, and the maximum number of fault nodes is LC0 and SFC0, the section of LC0 to SFC0 can be determined to be faulty.
If the gathered information is that LC0 to SFC0 to LC1 Fabric to LC1 Chip0 and SFC0 to LC1 Fabric are not passed, and the maximum number of fault nodes is SFC0 and LC1 Fabric, it can be determined that the segment from SFC0 to LC1 Fabric is faulty.
If the gathered information is that LC0 to SFC0 to LC1 Fabric to LC1 Chip0 and LC1 Fabric to LC1 Chip0 are not passed, and the largest number of fault nodes are LC1 Fabric and LC1 Chip0, the section from LC1 Fabric to LC1 Chip0 is determined to be faulty.
