With the development of computer, network and communication technologies, network management technologies are also increasing, and network fault management is one of the most basic functions in network management. Network element nodes of network equipment accessed into a network system are managed through network management, abnormal crash of the network equipment can occur during operation, the management node cannot receive a response of a managed node, and the managed node is out of management at the moment, such as situations of computer blue screen, router out of management and the like. Sometimes, the managed node is out of management only to be a task exception, the main service works normally, but the network management cannot manage the managed node and only the system is reset manually.
Under the condition of the prior art, in response to a small-probability serious event that a managed node is out of management, network equipment usually resets a system when no response is detected by adopting a hardware or software watchdog mode. The watchdog is actually a counter, and typically gives the watchdog a preset number, and the watchdog starts to count down after the program starts running. If the program runs normally, the CPU sends an instruction to reset the watchdog after a period of time, counting down is restarted, if the watchdog is reduced to 0, the program is considered not to work normally, and the whole system is forced to reset.
Although the hardware or software watchdog is adopted when the managed node is out of management, the partial stability of the network system can be improved, sometimes the watchdog is unreliable, and the watchdog is lack of flexibility, and when some faults which need to be kept on site without immediate reset occur, the watchdog can also force the whole system to reset, and the solution of potential problems is not helpful.

Fig. 1 is a schematic flow chart of a network device fault processing method according to an embodiment of the present invention, and as shown in fig. 1, the embodiment provides a network device fault processing method, including:
s101, receiving a special query message which is sent by a management node and used for querying fault information of a managed node by the managed node through a local bottom driver; the inquiry special message is determined by the management node and the managed node in advance;
specifically, after learning that the managed node is abnormal, the management node sends a special query message in a specific message format to the managed node for querying fault information of the managed node, and the managed node receives the special query message through the local bottom driver; the inquiry dedicated packet is determined by the management node and the managed node through negotiation in advance, and the bottom layer driver may identify and process the inquiry dedicated packet through a specific packet format determined by the management node and the managed node through negotiation in advance, or may identify and process the inquiry dedicated packet through other manners, which is not limited specifically here.
S102, the managed node returns the fault information to the management node through the local bottom layer driver, so that the management node performs fault processing on the managed node according to the fault information.
Specifically, after receiving the query dedicated packet sent by the management node, the managed node returns the fault information to the management node in the specific packet format through the local bottom layer driver, so that the management node performs fault processing on the managed node according to the fault information after receiving the fault information.
For example, a specific packet format negotiated in advance by the management node and the managed node is shown in table 1, where a destination PORT number of a UDP sent by the management node to the local bottom driver of the managed node is DST _ PORT, a source PORT number may be self-determined, and this is not specifically limited here; and when the local bottom layer driver of the managed node replies the message, interchanging the source port and the destination port of the received message. After the management node judges that the managed node is abnormal, a special query message with the specific message format and the OP (4) is sent to the managed node to query the fault information of the managed node, the managed node receives the special query message through the local bottom layer driver, sends a message with the specific message format and the OP (5) to the management node through the local bottom layer driver, and returns the fault information to the management node, so that the management node performs fault processing on the managed node according to the fault information after receiving the fault information.
TABLE 1
Wherein:
the OP-1 management node sends a special message for reset preparation to the managed node;
the OP is 2, the managed node replies a special response reset message to the management node;
the OP-3 management node sends a special message for immediate reset to the managed node;
the OP-4 managed node replies a special reset confirmation message to the management node and resets;
the OP-5 management node sends a special query message to the managed node to query the fault information;
the managed node with the OP being 6 responds to the command with the OP being 5 and returns fault information to the managing node;
the OP-7 management node sends a special command message to the managed node to request to execute the command;
the managed node with the OP being 8 responds to the command with the OP being 7, executes the command and replies a command execution result;
the OP is 9, the management node sends a message special for inquiring the bottom layer drive to the managed node, and inquires the bottom layer drive state information;
the OP-10 managed node responds to the inquiry request of OP-9 and replies the bottom-layer driving state information.
In the method for processing a network device fault provided by the embodiment of the present invention, after receiving, by a managed node, a query dedicated packet for querying fault information of the managed node, which is sent by a management node, through a local bottom driver, the managed node returns the fault information to the management node through the local bottom driver, so that the management node performs fault processing on the managed node according to the fault information, thereby improving flexibility of fault processing.
On the basis of the above embodiment, further, the method further includes:
and if the local bottom driver of the managed node judges that the upper protocol stack of the managed node is abnormal, processing and replying the received ARP message through the local bottom driver, and recording fault information corresponding to the upper protocol stack abnormality.
Specifically, if the local bottom driver of the managed node determines that the upper protocol stack of the managed node is abnormal according to a preset condition, the managed node receives an ARP packet sent by a router through the local bottom driver, and processes and replies the received ARP packet through the bottom driver, so as to maintain network connection between the managed node and the management node.
On the basis of the foregoing embodiment, further, if it is determined that the upper protocol stack exception of the managed node is known by the local bottom driver of the managed node, the method includes:
if the local bottom driver of the managed node judges that the received ARP message is not responded within the first preset time of the managed node; and/or
And the local bottom layer of the managed node is inquired to know that the residual number of the network port hardware buffer areas of the managed node is less than a first preset number, and then the upper layer protocol stack of the managed node is determined to be abnormal.
Specifically, under normal conditions, a router may periodically send an ARP packet to the managed node, a bottom driver of the managed node receives the ARP packet and transfers the ARP packet to an upper protocol stack of the managed node for processing and replying, and the ARP packet that has not been processed and replied in time is stored in a network port hardware buffer. If the managed node judges that the ARP message is received and transferred to the upper protocol stack, the upper protocol stack does not process and reply the ARP message within preset time, and the upper protocol stack is determined to be abnormal; if the local bottom layer driver of the managed node inquires that the residual number of the network port hardware buffer area of the managed node is smaller than the first preset number, it can also be determined that an upper layer protocol stack is abnormal, and the ARP message occupies the network port hardware buffer area due to being not processed in time, so that the residual number of the network port hardware buffer area is reduced. Of course, the local bottom driver of the managed node may also determine whether the upper protocol stack is abnormal in other ways, which is not specifically limited herein. It can be understood that, after the local bottom driver of the managed node judges that the upper protocol stack is abnormal, the managed node can increase a network port hardware buffer area by discarding an ARP packet that cannot be processed due to the abnormality of the upper protocol stack in time or by using a memory managed by a non-managed node, so as to ensure that the managed node reserves a certain number of network port hardware buffer areas for receiving and processing the dedicated packet.
For example, the managed node judges that the upper layer protocol stack of the managed node does not process and reply the ARP message within 2s after receiving the ARP message, and judges that the upper layer protocol stack is abnormal; and/or, if the local bottom layer driver of the managed node queries that the remaining number of the network port hardware buffer area of the managed node is less than 20% of the total number of the network port hardware buffer areas, it may also be determined that an upper layer protocol stack is abnormal.
In the method for processing a network device fault provided in the embodiment of the present invention, if the local bottom driver of the managed node determines that the upper protocol stack of the managed node is abnormal, the local bottom driver processes and replies the received ARP packet and records fault information corresponding to the upper protocol stack abnormality, and after the managed node receives, through the local bottom driver, a query dedicated packet sent by the management node and used for querying the fault information of the managed node, the fault information is returned to the management node by the local bottom driver, so that the management node performs fault processing on the managed node according to the fault information, thereby improving flexibility of fault processing.
In the foregoing embodiments, the fault information includes:
and when the upper protocol stack is abnormal, the state information, the statistical information, the task information and the memory information of the managed node are acquired.
Specifically, the fault information may include state information, statistical information, task information, and memory information of the managed node when the upper layer protocol stack is abnormal, or may include other information, which is not specifically limited herein. If the local bottom driver of the managed node judges that the upper protocol stack of the managed node is abnormal, the local bottom driver processes and replies the received ARP message and records state information, statistical information, task information and memory information corresponding to the managed node when the upper protocol stack is abnormal, and of course, the management node can also inquire the state information, the statistical information, the task information and the memory information corresponding to the managed node when the upper protocol stack recorded by the managed node is abnormal.
In the method for processing a network device fault provided by the embodiment of the present invention, after receiving, by a managed node, a query dedicated packet for querying fault information of the managed node, which is sent by a management node, through a local bottom driver, the managed node returns the fault information to the management node through the local bottom driver, so that the management node performs fault processing on the managed node according to the fault information, thereby improving flexibility of fault processing.
Fig. 2 is a schematic flow chart of a network device fault processing method according to another embodiment of the present invention, and as shown in fig. 2, a network device fault processing method according to an embodiment of the present invention includes:
s201, if judging that the managed node is abnormal, the management node sends a special query message for querying the fault information of the managed node to the managed node; the inquiry special message is determined by the management node and the managed node in advance;
specifically, after the management node judges that the managed node is abnormal, the management node sends a special query message in a specific message format to the managed node to query the fault information of the managed node, and the managed node receives the special query message through the local bottom driver; the inquiry dedicated packet is determined by the management node and the managed node through negotiation in advance, and the bottom layer driver may identify and process the inquiry dedicated packet through a specific packet format determined by the management node and the managed node through negotiation in advance, or may identify and process the inquiry dedicated packet through other manners, which is not limited specifically here. It can be understood that the management node may determine, according to a command packet, which is sent by the managed node and is not in the specific packet format, that the managed node does not respond to the command packet, which is sent by the management node within a preset time, that the managed node is abnormal, or may determine that the managed node is abnormal in other manners, which is not specifically limited herein.
S202, the management node receives the fault information returned by the managed node and carries out fault processing on the managed node according to the fault information.
Specifically, after receiving the query dedicated packet sent by the management node, the managed node returns the fault information to the management node in the specific packet format through the local bottom layer driver, and the management node receives the fault information returned by the managed node and performs fault processing on the managed node according to the fault information.
For example, referring to table 1, where the UDP destination PORT number sent by the management node to the local bottom driver of the managed node is DST _ PORT, the source PORT number may be self-determined, and is not specifically limited herein; and when the local bottom layer driver of the managed node replies the message, interchanging the source port and the destination port of the received message. After the management node judges that the managed node is abnormal, the management node sends an inquiry special message with the specific message format and OP (4) to the managed node to inquire the fault information of the managed node, the managed node receives the inquiry special message through the local bottom layer driver, sends a message with the specific message format and OP (5) to the management node through the local bottom layer driver, and returns the fault information to the management node, and the management node carries out fault processing on the managed node according to the fault information after receiving the fault information.
In the method for processing a network device fault provided in the embodiment of the present invention, if the management node determines that the managed node is abnormal, the management node sends a query dedicated packet for querying fault information of the managed node to the managed node, receives the fault information returned by the managed node, and performs fault processing on the managed node according to the fault information, thereby improving flexibility of fault processing.
On the basis of the foregoing embodiment, further performing fault processing on the managed node according to the fault information includes:
and if the management node judges that the managed node needs to be immediately reset according to the fault information, the management node sends a special reset message to the managed node so as to immediately reset the managed node.
Specifically, if the management node determines that the managed node needs to be immediately reset according to the received fault information returned by the managed node, the management node sends a reset dedicated message to the managed node, so that the managed node is immediately reset. It can be understood that the management node may match the fault information returned by the managed node according to a plurality of types of fault information counted in the past, and determine that the managed node needs to be immediately reset if it is determined that the fault information returned by the managed node matches the fault information that needs to be immediately reset; the fault information returned by the managed node is displayed through a display device, confirmation information used for prompting whether reset is needed is displayed, and after the confirmation information sent when the fact that the managed node needs to be reset immediately is judged manually according to experience is received, the fact that the managed node needs to be reset immediately is determined.
For example, after receiving the fault information returned by the managed node, the management node displays the fault information through a display device, and displays a dialog box of "whether reset is required" on the display device, and when it is determined manually according to the fault information in combination with experience that the managed node needs to be reset immediately, clicks "yes" in the dialog box of "whether reset is required", and when the management node determines that the managed node needs to be reset immediately, the management node sends a reset dedicated message to the managed node, so that the managed node is reset immediately.
In the method for processing a network device fault provided in the embodiment of the present invention, if it is determined that a managed node is abnormal, a management node sends a query dedicated packet for querying fault information of the managed node to the managed node, receives the fault information returned by the managed node, and sends a reset dedicated packet to the managed node when it is determined that the managed node needs to be immediately reset according to the fault information, so that the managed node is immediately reset, thereby improving flexibility of fault processing.
On the basis of the foregoing embodiment, further performing fault processing on the managed node according to the fault information includes:
and if the management node judges that the managed node does not need to be immediately reset according to the fault information, the management node sends a special command message to the managed node, so that the managed node executes a corresponding command and replies a command execution result to the management node.
Specifically, if the management node determines that the managed node does not need to be immediately reset according to the received fault information returned by the managed node, the management node sends the special command packet in the specific format to the managed node, so that the managed node executes a corresponding command and replies a command execution result to the management node. It can be understood that the management node may match the fault information returned by the managed node according to a plurality of types of fault information counted in the past, and determine that the managed node does not need to be immediately reset if it is determined that the fault information returned by the managed node is not matched with the fault information that needs to be immediately reset; the fault information returned by the managed node is displayed through a display device, confirmation information used for prompting whether reset is needed or not is displayed, and the managed node is determined not to need to be reset immediately after the confirmation information which is selected not to need to be reset immediately when the fact that the managed node does not need to be reset immediately is judged manually according to experience is received.
For example, referring to table 1, after receiving the fault information returned by the managed node, the management node displays the fault information through a display device, and displays a dialog box of "whether reset is required" on the display device, and when it is determined manually according to experience that the managed node does not need to be reset immediately according to the fault information, if it is determined that the managed node does not need to be reset immediately, the management node clicks "no" in the dialog box of "whether reset is required", and determines that the managed node does not need to be reset immediately, the management node sends a command-specific message in a specific format with an OP of 7 to the managed node, so that the managed node executes a corresponding command and sends a message in a specific format with an OP of 8 to the management node, and replies a command execution result to the management node.
In the method for processing a network device fault provided in the embodiments of the present invention, if it is determined that a managed node is abnormal, a management node sends a query dedicated packet for querying fault information of the managed node to the managed node, receives the fault information returned by the managed node, and sends a command dedicated packet to the managed node when it is determined that the managed node does not need to be immediately reset according to the fault information, and the managed node executes a corresponding command and replies a command execution result to the management node, thereby improving flexibility of fault processing.
On the basis of the foregoing embodiment, further, the sending a reset dedicated packet to the managed node includes:
sending a special message for resetting preparation to the managed node;
after receiving the response reset special message returned by the managed node, sending an immediate reset special message to the managed node, so that the managed node is reset and returns a reset confirmation special message to the management node.
Specifically, when the management node judges that the managed node needs to be immediately reset according to the fault information returned by the managed node, the management node sends a special reset preparation message with a specific format to the managed node; the managed node returns a response reset special message to the management node after receiving the preparation reset special message, and the management node sends an immediate reset special message to the managed node after receiving the response reset special message returned by the managed node, so that the managed node is reset and returns a reset confirmation special message to the management node.
For example, continuing to refer to table 1, when the management node determines that the managed node needs to be immediately reset according to the fault information returned by the managed node, the management node sends a special reset-preparing message with an OP of 1 to the managed node; the managed node receives the special reset preparation message and sends a special reset response message with OP being 2 to the management node; after receiving the response reset special message returned by the managed node, the management node sends an immediate reset special message with the OP of 3 to the managed node, so that the managed node resets and returns a confirmation reset special message with the OP of 4 to the management node. It is understood that the OP-1 message dedicated to preparation reset may include a password encrypted by a key, and accordingly, the information in the OP-2 message dedicated to response reset includes information of a password error or successful operation. In addition, before the management node sends the preparation reset dedicated message to the managed node, a query bottom layer driving dedicated message with OP-9 may be sent to the managed node to query the bottom layer driving state information, and the managed node replies a message with OP-10 to the management node and replies the bottom layer driving state information in response to the query request with OP-9.
In the method for processing a network device fault provided in the embodiment of the present invention, if it is determined that a managed node is abnormal, a management node sends a query dedicated packet for querying fault information of the managed node to the managed node, receives the fault information returned by the managed node, and when it is determined that the managed node needs to be immediately reset according to the fault information, sends a reset dedicated packet to the managed node, so that the managed node is immediately reset, thereby improving flexibility of fault processing and safety of fault processing.
