Detailed Description
The present application is described more fully hereinafter with reference to the accompanying drawings of illustrative embodiments of the application. This application may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. The embodiments described above are intended to be a complete and complete disclosure of the present disclosure, so as to more fully convey the scope of the present application to those skilled in the art.
In the present specification, words such as "comprise" and "comprises" mean that in addition to elements and steps directly and unequivocally stated in the specification and claims, the technical solutions of the present application do not exclude other elements and steps not directly or unequivocally stated.
Terms such as "first" and "second" do not denote an order of the elements in time, space, size, etc., but rather are used to distinguish one element from another.
In this specification, a pdu (power Distribution unit) device refers to a power Distribution unit that is connected between a network device and a power supply as a power Distribution outlet for a cabinet, thereby providing power Distribution for the network device.
In this specification, network devices may include, but are not limited to, switches, routers, firewalls, Intrusion Prevention Systems (IPS), and the like. Embodiments of a deployment architecture for a system for monitoring the status of network tunnels are described below with switches and routers as examples. However, it should be noted that the embodiments described herein are equally applicable to a variety of other network devices.
FIG. 1 illustrates a schematic block diagram of a system for monitoring a status of a network channel in accordance with some embodiments of the present application. The system 10 for monitoring the status of a network path shown in fig. 1 comprises a monitoring unit 110, a judging unit 120 and a processing unit 130. Illustratively, the network channel may be connected between data centers to provide a channel for data transmission between the two.
The monitoring unit 110 may be disposed at each of a plurality of nodes included in the network channel and configured to monitor a status of a network device at the respective node to generate a monitoring result. As an example, the monitoring unit 110 may be configured to monitor a communication status of the network devices at the corresponding nodes, and when the monitoring unit 110 monitors that the network device at a node cannot communicate with the network devices at other nodes, generate a corresponding monitoring result to alert the network device at the node of the abnormality.
Alternatively, the monitoring unit 110 may have a binding relationship with the network devices at the respective nodes and be connected with ports of the bound network devices.
Optionally, the monitoring unit 110 is further configured to monitor the status of the network devices at the respective nodes using service commands based on one or more of the following protocols: ICMP, TCP, HTTP network protocols. For example, the monitoring unit 110 may use various service commands such as Ping, Crul, Nc, etc. in various network protocols to monitor the status of the network devices at the respective nodes. In one example, the monitoring unit 110 may use Ping commands to monitor whether the local network device can successfully exchange (e.g., send and receive) data packets with another network device, and then infer from the returned information whether the TCP/IP parameters of the local network device are set correctly and are running normally, the network is unobstructed, and the like, thereby generating corresponding monitoring results. In another example, the monitoring unit 110 may use Nc commands to establish and listen to any TCP and UDP connections of the network device, thereby generating corresponding monitoring results.
By using various service commands in the various network protocols, the comprehensiveness and the accuracy of the monitoring process can be improved, and different network protocols can cover different network OSI layers.
In addition, a plurality of nodes in the network channel can support capacity expansion, for example, the nodes can be expanded according to monitoring requirements to improve the monitoring range, so that full-coverage monitoring of the network equipment is realized.
The monitoring unit 110 may be implemented as a monitoring server directly connected to a port of a network device, or any other device having a monitoring function.
The determination unit 120 may be configured to determine whether a state of the network device is abnormal based on the monitoring result and generate an automatic disposition command when the state is abnormal. Optionally, the auto-handle command may indicate an occurrence time of an anomaly of the network device, an identification of the anomalous network device, an identification of a PDU device socket to which the anomalous network device is connected, and the like. Optionally, the automatic processing command may further indicate an identifier of a PDU device socket connected to the standby machine corresponding to the network device in which the abnormality occurs.
Optionally, the determining unit 120 is further configured to perform the following operations: periodically determining whether the state of the network device at the corresponding node is abnormal based on the monitoring result received from the monitoring unit 110; generating an automatic disposition command in response to a determination result that the abnormality occurs; issue an automatic disposition command to the processing unit 130; and generating alarm information in response to the abnormal judgment result so as to inform relevant personnel to pay attention, so that the relevant personnel can conveniently perform subsequent processing. Optionally, the automatic disposition command and the alert information may be generated substantially synchronously. As an example, when each monitoring unit 110 transmits the monitoring result to the determination unit 120, the determination unit 120 completes the warehousing of the information of the monitoring result and periodically (e.g., every 30 seconds) determines whether the state of the network device at the corresponding node is abnormal based on the monitoring result. An auto-disposition command is generated when it is judged that the state of the network device at the corresponding node is abnormal, and the auto-disposition command is issued to the processing unit 130. Meanwhile, the determination unit 120 may be configured to generate an alarm command in response to a determination result of the occurrence of the abnormality to notify the relevant person of attention, so as to facilitate subsequent processing by the relevant person.
Optionally, the determining unit 120 is further configured to perform the following operations: monitoring whether the monitoring unit 110 uploads a monitoring result within a set time; and generating alarm information in response to an event that the monitoring unit 110 does not upload the monitoring result within a set time. As an example, the determining unit 120 may be configured to monitor whether all the monitoring units 110 upload the monitoring results every 15 seconds, so as to monitor the states of the monitoring units 110, thereby effectively preventing the monitoring units 110 from failing to obtain the monitoring results. Thereby, the reliability of the monitoring process performed by the monitoring unit 110 is further improved.
The processing unit 130 may be configured to perform exception handling operations for network devices at respective nodes based on the auto-handle command. Optionally, the exception handling operation includes implementing a master/slave switching operation between the network devices by remotely controlling the PDU device. As an example, the network device may be equipped with a high availability mechanism, i.e., the network device is deployed in a master standby mode. During normal operation, various services are provided by the host of the network device, and the standby of the network device is enabled to take over the services when the host of the network device is abnormal.
However, in the implementation process, although the network device may be equipped with a high availability mechanism, when conditions such as network device performance degradation, network device blocking, and the like occur, the data center surface may not seem to have an influence on the operation of part of the traffic, resulting in failure to generate a complete monitoring result. In view of this, the monitoring unit 110 monitors the states of the network devices at the corresponding nodes by using the multiple network protocols and the multiple service commands corresponding thereto, so as to ensure that various non-perceptible abnormal states of the network devices are monitored in time, thereby improving the comprehensiveness and accuracy of the monitoring process, and meanwhile, different network protocols can cover different network OSI layers.
Optionally, the processing unit 130 is further configured to perform active/standby switching between the network devices via the PDU device, so as to implement exception handling on the network devices at the corresponding nodes. As an example, the processing unit 130 may instruct the PDU device to disconnect the network device in which the abnormality occurs from the power supply by way of remote control based on the identification of the network device in which the abnormality occurs, which is indicated by the received auto-disposition command. In order to shorten the process of master/slave switching, processing unit 130 optionally performs disconnection of a pair of PDUs from the network device in a synchronous manner or a nearly synchronous manner. By the synchronous or nearly synchronous mode, the abnormal events can be processed quickly without sensing by the outside.
Optionally, the processing unit 130 may implement remote control on the PDU device through an ssh (secure shell) secure channel protocol to implement active/standby switching by using a high availability mechanism of the network device, so as to reduce the influence of the exception handling operation on the data center.
Optionally, the above-mentioned determining unit 120 and the processing unit 130 may be disposed at a node where the core switch is located, so as to improve the reliability and efficiency of the determination for the abnormal network device and the abnormal processing operation.
Although not shown in fig. 1, the system 10 for monitoring the status of the network channel may further include various other functional modules, such as a monitoring unit management module, a judgment unit management module, a processing unit management module, a device deployment information management module, an emergency manual management module, an alarm notification management module, and the like, so that multi-module integration can be implemented in the system 10 for monitoring the status of the network channel to provide more efficient and convenient operation and maintenance services for operation and maintenance personnel.
According to the system for monitoring the state of the network channel, the state of the network equipment at multiple nodes on the network channel can be monitored, abnormal network equipment is judged, and the automatic handling of the abnormal network equipment is integrated, so that the operation and maintenance difficulty and the management cost of the data center are obviously reduced, and the safety and the reliability of the data center are improved. In addition, compared with the existing abnormal device processing flow or means, the integrated operation improves the processing efficiency for the abnormal device, and meanwhile, the influence of the abnormal network device on the data center is reduced through the main/standby switching operation of the abnormal network device.
Fig. 2 illustrates a deployment architecture diagram of a system for monitoring the status of a network channel in accordance with some embodiments of the present application.
Referring to fig. 2, each circle represents a monitoring node in a network path, where a corresponding monitoring unit may be deployed at monitoring nodes 1-11 as shown. Illustratively, the monitoring units deployed at monitoring nodes 1-11 may have the features and structure of monitoring unit 110, wherein the monitoring unit deployed at monitoring node 11 is configured to monitor the state of switches in network a and generate monitoring results, the monitoring unit deployed at monitoring node 10 is configured to monitor the state of firewall switches in network a and generate monitoring results, and the monitoring unit deployed at monitoring node 9 is configured to monitor the state of routers in network B and generate monitoring results.
It is understood that the number and the deployment location of the monitoring nodes 1-11 shown in fig. 2 are only exemplary, a person skilled in the art may deploy the monitoring units at other monitoring nodes according to the actual needs of the data center, and the number of monitoring nodes or monitoring units is not limited to the specific example shown in fig. 2. It will be appreciated that the monitoring node may be selected based on the network architecture of the data center to maximize coverage of various network devices. In addition, the monitoring node can support the dilatation, and is applicable to novel cloud network framework, for example can carry out the dilatation to the node according to the monitoring demand in order to further promote monitoring range to the realization is to network equipment's full coverage monitoring.
Alternatively, the determination unit 120 and the processing unit 130 shown in fig. 1 may be disposed at a node (e.g., the monitoring node 5 shown in fig. 2) where the core switch is located, where the determination unit 120 may receive monitoring results generated from the monitoring units 110 disposed at the respective monitoring nodes (e.g., the monitoring nodes 1 to 11) and determine whether the state of the network device is abnormal based on the monitoring results, and generate an auto-disposition command when the state is abnormal, and the processing unit 130 may perform an abnormal processing operation on the network device at the corresponding monitoring node based on the auto-disposition command. By deploying the determination unit 120 and the processing unit 130 at the node where the core switch is located, the determination unit 120 can determine, based on the monitoring result, the network device in which the abnormality occurs and generate the automatic handling command at the first time, and the processing unit 130 can perform, based on the automatic handling command, the abnormality processing operation on the network device at the corresponding monitoring node at the first time, thereby improving the reliability and efficiency of the determination for the abnormal network device and the abnormality processing operation.
Optionally, the automatic disposition command may include an exception occurrence time of the network device, an identifier of the abnormal network device, an identifier of the PDU device socket connected to the standby device corresponding to the abnormal network device, and the like. Alternatively, the binding relationship between the abnormal network device and the standby device is stored at the processing unit 130, so that the processing unit can find the identifier of the PDU device socket connected to the corresponding standby device based on the identifier of the abnormal network device.
Optionally, various network devices (e.g., a switch, a router, a firewall, and an IPS) shown in fig. 2 are connected to the power supply via the PDU device, so that the processing unit 130 can implement active/standby switching of the network devices by remotely controlling a socket specified in the PDU device, thereby completing exception handling of the network devices at the corresponding monitoring nodes.
For example, when the determination unit 120 determines that an abnormality occurs in the switch at the monitoring node 11 based on the monitoring result, an auto-disposal command may be generated and transmitted to the processing unit 130. The processing unit 130 instructs the PDU device to cut off the connection between its socket and the switch based on the identification of the switch where the exception occurs, which is indicated by the received auto-disposition command; at the same time. Therefore, the fast switching operation between the host machine and the standby machine is realized.
Alternatively, the determination unit 120 may generate alarm information in response to the determination result of the occurrence of the abnormality to notify the relevant person of attention, so as to facilitate subsequent processing by the relevant person. Meanwhile, the determining unit 120 may monitor whether the monitoring units 110 deployed at the monitoring nodes upload monitoring results within a set time; and generating alarm information in response to an event that the monitoring unit 110 does not upload the monitoring result within a set time. For example, the determining unit 120 may monitor whether all the monitoring units 110 upload the monitoring results every 15 seconds, so as to monitor the states of the monitoring units 110, thereby effectively preventing the monitoring units 110 from failing to obtain the monitoring results. Thereby, the reliability of the monitoring process performed by the monitoring unit 110 is further improved.
It is understood that the deployment architecture of the system for monitoring the status of the network channel shown in fig. 2 above is only exemplary, and those skilled in the art can implement other deployment architectures according to the actual needs of the data center (e.g., network device monitoring of multi-level multi-network protocol, monitoring of decentralized network devices).
Fig. 3 is a flow diagram of a method for monitoring a status of a network channel in accordance with some embodiments of the present application.
In these embodiments, the steps in the method flow are implemented by means of the computer device shown in fig. 4 below or the above determination unit 120 shown in fig. 1.
In step 310, the monitoring results are received from the monitoring unit 110.
In step 320, it is determined whether the state of the network device is abnormal based on the monitoring result and an auto-handle command is generated when the state is abnormal. Optionally, the auto-handle command may indicate an occurrence time of an anomaly of the network device, an identification of the anomalous network device, an identification of a PDU device socket to which the anomalous network device is connected. Optionally, the automatic processing command may further indicate an identification of the PDU device socket to which the standby corresponding to the abnormal network device is connected.
In step 330, an auto-handle command is sent to the processing unit 130 to cause the processing unit 130 to perform exception handling operations for the network devices at the respective nodes based on the auto-handle command.
Alternatively, step 320 may be performed in the following manner: periodically determining whether the state of the network device at the corresponding node is abnormal based on the monitoring result received from the monitoring unit 110; generating the automatic handling command in response to a determination result that an abnormality occurs; and issuing the automatic disposition command to the processing unit 130.
Optionally, the method further includes generating warning information in response to the determination result of the occurrence of the abnormality to notify the relevant person to pay attention, so that the relevant person can perform subsequent processing conveniently.
Optionally, the method further includes monitoring whether the monitoring unit 110 uploads the monitoring result within a set time; and generating alarm information in response to an event that the monitoring unit 110 does not upload the monitoring result within a set time.
According to the method for monitoring the state of the network channel, the state of the network equipment at multiple nodes on the network channel can be monitored, abnormal network equipment is judged, and the abnormal network equipment is automatically disposed, so that the operation and maintenance difficulty and the management cost of the data center are obviously reduced, and the safety and the reliability of the data center are improved. In addition, compared with the existing abnormal device processing flow or means, the integrated operation improves the processing efficiency of the abnormal device, and meanwhile, the influence of the abnormal network device on the data center is reduced through the main/standby switching operation of the abnormal network device.

The memory 410 stores a computer program 430 executable by the processor 420. The processor 420 is configured to execute the computer program 430 to implement a corresponding method flow for monitoring the status of a network channel.
