By clicking on the submission, some or all of the steps of the network status monitoring method provided by the present application may begin to be performed.
Specifically, please refer to fig. 3, where fig. 3 is a flowchart of a network status monitoring method according to an embodiment of the present application, and the method is applied to a network controller. The method comprises the following steps:
s101: and acquiring monitoring range information, and determining at least one target node according to the monitoring range information.
The monitoring range information is used for determining a network range for receiving the monitoring state, and the monitored node can be determined according to the monitoring range information. The data form of the monitoring range information is not limited in this embodiment, and may be, for example, a node number of the target node or a network address of the target node. In one embodiment, the monitoring range information may be manually entered by a user; in another embodiment, the monitoring range information may be imported from the outside, for example, the monitoring range information sent by a specific device may be received, or the monitoring range information may be read from an accessed removable storage device, or the monitoring range information may be acquired from a cloud; in another embodiment, a plurality of candidate range information may be pre-stored locally, and when the network state monitoring is required, one of the candidate range information is selected as the monitoring range information, for example, the monitoring range information may be selected according to an input selection instruction, so as to complete the acquisition of the monitoring range information.
After the monitoring range information is obtained, the corresponding target node can be determined according to the monitoring range information. The number of the target nodes is multiple, each target node and at least one other target node are provided with a communication link, and each communication link and the target node jointly form a network subjected to state monitoring. The present embodiment does not limit the device type of the target node, and the types of the target nodes may be the same or different.
S102: and sending the monitoring configuration information to each target node so that each target node establishes a monitoring link by using the monitoring configuration information.
The monitoring configuration information is used to instruct the target node to establish the monitoring link, and specifically, the monitoring configuration information includes neighbor node information used to instruct neighbor nodes corresponding to each target node, so as to establish the monitoring link between the target node and the neighbor nodes. It should be noted that the monitoring configuration information corresponding to each target node is different. In another embodiment, monitoring mode information may be further included, which is used to specify a specific mode for establishing the monitoring link and a specific form of the monitoring link. The specific form of the monitoring link is not limited, and for example, the monitoring link may be a BFD (Bidirectional Forwarding Detection, which is a Bidirectional Forwarding Detection mechanism and can provide millisecond Detection and implement fast Detection of the link) link. The monitoring configuration information may be locally generated, for example, after the monitoring range information is acquired, corresponding monitoring configuration information may be generated for each target node according to the monitoring range information and the network topology. In another embodiment, the monitoring configuration information may be obtained from the outside, for example, corresponding monitoring configuration information may be obtained simultaneously when the monitoring range information is obtained, and each monitoring configuration information is issued according to the corresponding relationship between the monitoring configuration information and the target node. By issuing the monitoring configuration information, the target node can determine the neighbor node by using the monitoring configuration information, and then a monitoring link is established between the target node and the neighbor node. The establishment mode of the monitoring link is not limited, for example, whether a link establishment request sent by a neighbor node is received or not can be judged; if the link establishment request is received, sending a link establishment request to the neighbor node; and if so, responding to the link establishment request.
In a possible implementation, the network controller and each target node have a communication link therebetween, so that the monitoring configuration information can be directly sent to each target node. In another possible embodiment, part of the target nodes in the network subject to condition monitoring and the network controller do not have a direct communication link, in which case the process of sending the monitoring configuration information to each target node may include the following steps:
step 11: a forwarding node is determined in the target node.
In this embodiment, the forwarding nodes are target nodes having direct communication links with the network controller, and the number of the forwarding nodes is less than or equal to the number of all the target nodes. As for the determination method of the forwarding node, in a specific implementation manner, all or part of nodes directly connected to the network controller may be labeled in advance, and determined as candidate forwarding nodes, information of the candidate forwarding nodes is stored in the network controller, and after the monitoring range is determined, the candidate forwarding nodes in the monitoring range are determined as the forwarding nodes.
Step 12: and sending the monitoring configuration information to the forwarding node so that the forwarding node forwards the monitoring configuration information to the rest target nodes.
After the forwarding node is determined, the monitoring configuration information is sent to the forwarding node, so that the forwarding node forwards the monitoring configuration information to other target nodes. It can be understood that, in an embodiment, the monitoring configuration information sent by the network controller to each forwarding node is completely the same, and the forwarding node selects part of the monitoring configuration information to forward; in a second embodiment, the monitoring configuration information sent by the network controller to each forwarding node is completely the same, and the forwarding nodes forward all the acquired monitoring configuration information; in the third embodiment, the forwarding node only obtains monitoring configuration information that the forwarding node can forward, and selects part of the monitoring configuration information to forward; in the fourth embodiment, the forwarding node only acquires monitoring configuration information that it can forward, and forwards all the acquired monitoring configuration information.
The four embodiments described above will be specifically described below by way of examples. For example, there are A, B, C, D, E five target nodes in the monitoring range, the node a and the node D are forwarding nodes, the node a has a communication link with the node B and the node C, does not have a communication link with the node D, and has a communication link with the node D.
For monitoring configuration information acquired by a node a and a node D in the first embodiment, which is monitoring configuration information corresponding to A, B, C, D, E five nodes, after acquiring all monitoring configuration information, the node a sends a part corresponding to a node B to the node B, and a part corresponding to a node C to the node C, or sends parts corresponding to the node B and the node C together, that is, both the node B and the node C acquire monitoring configuration information corresponding to both the node B and the node C, and the node B and the node C screen out content corresponding to the node B from the acquired monitoring configuration information, for example, parts of the monitoring configuration information corresponding to different nodes have different node identity information (for example, node serial numbers), and each node may select a part matching with itself as content corresponding to itself. And after the D node acquires all the configuration information, sending the part corresponding to the E node.
For the second embodiment, the monitoring configuration information acquired by the node a and the node D is A, B, C, D, E monitoring configuration information corresponding to five nodes, after the node a and the node D acquire all the configuration information, the node a and the node D send the monitoring configuration information corresponding to the A, B, C, D, E five nodes to the B, C, E node, and the B, C, E node screens out the content corresponding to the node a from the acquired monitoring configuration information.
For the third embodiment, the monitoring configuration information acquired by the node a is A, B, C and the monitoring configuration information corresponding to three nodes, and the monitoring configuration information acquired by the node D is D, E and the monitoring configuration information corresponding to two nodes. After the node A acquires all the monitoring configuration information, the part corresponding to the node B is sent to the node B, the part corresponding to the node C is sent to the node C, or the parts corresponding to the node B and the node C are sent to the node B and the node C together. And after the D node acquires all the configuration information, sending the part corresponding to the E node.
For the fourth embodiment, the monitoring configuration information acquired by the node a is A, B, C and the monitoring configuration information corresponds to three nodes, and the monitoring configuration information acquired by the node D is D, E and the monitoring configuration information corresponds to two nodes. After the node A acquires the configuration information, monitoring configuration information corresponding to A, B, C three nodes is sent to the node B, C, and after the node D acquires the configuration information, monitoring configuration information corresponding to D, E two nodes is sent to the node E. B. C, E node screens out the corresponding content from the acquired monitoring configuration information.
Or may be A, B, C, D monitoring configuration information corresponding to the four nodes. During the delivery, the node a may send all the acquired monitoring configuration information to the node B, or only send the monitoring configuration information corresponding to the node B. By using the method, the monitoring configuration information can be issued to all target nodes under the condition of various network topologies.
S103: and receiving node network information which is sent by a target node and obtained based on the monitoring link, and generating network state information by utilizing the node network information.
After the monitoring configuration information is sent, the target node can establish a monitoring link and monitor the state of the network based on the monitoring link, namely, the monitoring link is used for judging whether the network communication state between the target node and each neighbor node is normal or not. The target node combines the detection results corresponding to the monitoring links of the target node to obtain corresponding node network information, so that the node network information can indicate whether the network communication state between the target node and the neighbor nodes is normal or not. The network controller receives and combines the node network information of each target node to generate the network state information capable of reflecting the network state, so that the network state information can indicate whether the network communication state among each node in the network formed by the target nodes is normal or not, and the state monitoring of the network is completed. In a specific implementation manner, the network state information is specifically information indicating whether a communication link between the target node and a corresponding neighboring node is normally connected, where the connection is normal and may be represented by a character 1, and the connection is disconnected or abnormal and may be represented by a character 0; in another embodiment, the network state information may indicate whether the communication speed of the communication link between the target node and its corresponding neighbor node is normal, for example, to indicate whether the signal transmission speed is lower than a threshold value; in another embodiment, the network state information may indicate whether signal quality of a communication link between the target node and its corresponding neighbor node is normal. It should be noted that the network controller may receive the node network information sent by all the target nodes at each time of receiving, and generate the network state information by using the new node network information; in another embodiment, the network controller may receive node network information sent by a part of nodes, update current network state information with new node network information to obtain new network state information, that is, replace old node network information corresponding to the target node with the new node network information, and generate new network state information together with node network information newly sent by other target nodes. The network status information may be in the form of a graph or may be in the form of data. By generating the network state information, the network fault or abnormity can be timely found when the network is in fault or abnormity, fault or abnormity positioning is carried out without checking the state information of each node, and the positioning speed is improved.
In one possible embodiment, the network status information may be provided in the form of a topology map in order to enable a user to visually view the network status information. In this case, the step of receiving node network information sent by the target node and obtained based on the monitored link, and generating network state information by using the node network information may specifically include:
step 21: and receiving node network information respectively sent by each target node, and integrating the node network information to obtain link state information.
In this embodiment, each target node may send node network information to the network controller, and the node network information of different target nodes may include information corresponding to the same monitoring link. The present embodiment does not limit the specific type of the fault, and for example, the fault may be an operation fault of a node, for example, a node downtime; or it may be a node communication failure, i.e. the node communication therefore needs to be integrated after obtaining the node network information. The specific process of the integration processing is not limited, for example, the information corresponding to the same monitoring link is deduplicated; or the missing node network information can be filled by using the standard abnormal information to obtain the link state information.
Step 22: and generating a network state topological graph by using the link state information, and determining the network state topological graph as the network state information.
The link state information can reflect the state information of each monitoring link in the monitoring range, so the generated network state topological graph can intuitively reflect the state of each monitoring link in the network, and further intuitively reflect the state of the network.
In another possible implementation manner, in order to enable the user to know the network abnormality in time and then perform abnormality repairing in time, the embodiment may further include the following steps:
step 31: and carrying out network anomaly detection on the network state information.
It should be noted that, the embodiment does not limit the specific manner of network anomaly detection, and the manner of network anomaly detection may also be different according to the form of the network state information. For example, when the network state information is in a data form, whether an abnormal mark exists in the network state information can be judged, and if the abnormal mark exists, the network state information is determined to be detected; or when the network state information is in the form of a topological graph, comparing the network state information with the network topology to judge whether topology loss or topology abnormity exists, and if the topology loss or topology abnormity exists, determining that the network abnormity is detected.
Step 32: and if the network abnormality is detected, performing abnormality alarm.
If the network abnormality is detected, an abnormality alarm can be performed, and the alarm form of the abnormality alarm is not limited, and can be one or more of a video alarm, an audio alarm, a notification alarm and the like.
By applying the network state monitoring method provided by the embodiment of the application, the network controller sends monitoring configuration information to the target nodes in the monitoring range, and the target nodes can establish monitoring links among the nodes after acquiring the monitoring configuration information. The monitoring link is only used for monitoring the network communication condition between two target nodes. After the monitoring link is established, the target node can acquire node network information by using the monitoring link, and the node network information can represent the network communication condition between the target node and each neighbor node. The target node sends the node network information to the network controller after acquiring the node network information, the network controller can further generate network state information by using the node network information, and the network state information can represent the conditions of each target node and each link in a monitoring range, so that the network state can be rapidly and accurately monitored by using the node network information, the abnormal reason can be timely determined when the network is abnormal, and further fault recovery is rapidly performed. Network state information can be generated by the monitoring link established at the target node and acquiring node network information sent by the target node based on the monitoring link. The network state information can represent the network condition in the monitoring range information, and the abnormal position can be quickly determined based on the network state information when the network link, the node and the like are abnormal or have faults.

s201: and receiving monitoring configuration information sent by the network controller.
It will be appreciated that the monitoring configuration information may be sent directly by the network controller; in another embodiment, the monitoring configuration information may be forwarded by a forwarding node, in this case, the step S201 may specifically be:
step 41: monitoring configuration information forwarded by the forwarding node is received.
S202: and establishing a monitoring link with the neighbor node by using the monitoring configuration information.
It should be noted that the neighbor node in this embodiment may be a physical neighbor node, or may also be a logical neighbor node, that is, a neighbor node on a link or a neighbor node of a specified different network segment. The specific process of establishing the monitoring link is related to the type of the monitoring link, and the specific establishing process is not limited in this embodiment. The number of monitoring links corresponding to one target node is not limited, and may be multiple.

It should be noted that, the generation and sending time of the node network information is not limited in this embodiment, for example, in an implementation, the node network information may be generated according to a preset period; in another embodiment, the node network information is sent once after the monitoring link is established for the first time, so that the network controller initializes the network state information, and the node network information is generated and sent only when the change of the communication state of the monitoring link is detected in the following.
It can be understood that, if the monitoring configuration information is forwarded by the forwarding node, the node network information cannot be directly sent to the network controller, and therefore, the process of sending the node network information to the network controller may specifically include the following steps:
step 42: and sending the node network information to the forwarding node so that the forwarding node sends the node network information to the network controller.
In a specific embodiment, in order to avoid the waste of computing resources, the target node may upload the node network information when detecting that the communication state of a certain monitoring link changes. The process of obtaining the node network information based on the monitoring link and sending the node network information to the network controller may specifically include the following steps:

It should be noted that the customized network region may cover different network segments, and therefore, the neighbor node of each target node may be a neighbor device node on a link, and may also be a logical neighbor device node, that is, the target node and the neighbor node are designated neighbor device nodes in different network segments. After the network neighbor information table is created, a BFD session is created according to the network neighbor information table and a neighbor node, and a network neighbor communication quality table is created at the same time. The network neighbor communication quality table is the node network information, and the updating and reporting of the node network information can be completed by starting the quality table and updating the state machine. And in the circulating process of the state machine, periodically updating the state machine according to the BFD monitoring state, further updating a network neighbor communication quality table by using the state machine, and reporting the quality table to the network controller. If a network communication fault is detected, the state machine can be updated, the quality table is updated, and the network controller can know the network state in a quality target reporting mode.
Referring to fig. 6, fig. 6 is a schematic diagram of a specific network topology according to an embodiment of the present application. After receiving the "network monitoring" configuration (i.e., the monitoring configuration information), the network node device in the customized network area starts network monitoring according to a network monitoring start-up procedure (i.e., as shown in fig. 5), and periodically reports the network neighbor communication quality table to the network controller. When the link between the sw5 and the sw2 has network failure, the sw2 can quickly detect the communication failure through the BFD module. The BFD module in sw2 reports the monitored communication failures to the "network monitoring" function. And after receiving the communication fault report, the network monitoring module updates the network neighbor communication quality table corresponding to the user-defined network area in the sw2 according to the relevant information of the communication fault report. After the network monitoring module finishes updating the network neighbor communication quality table, the network monitoring module immediately reports the network neighbor communication quality table to the network controller. And after receiving the network neighbor communication quality table reported by the sw2, the network controller updates the network neighbor communication quality table corresponding to the user-defined network area in the network controller. When a network administrator checks the communication state in the user-defined network area through the network controller, the network controller draws the current communication state according to the network neighbor communication quality table in the user-defined network area, and the network administrator can very intuitively check the node or link where the network fault occurs in the current user-defined area.
