[0025] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0026] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0027] Figure 1 A flow chart of a campus network quality evaluation method provided for one or more embodiments of this specification. The method can be applied to different types of campuses for network evaluation. The process can be executed by computing devices in the corresponding field. Certain input parameters or intermediate results in the process allow manual intervention and adjustment to help improve accuracy.

[0028] The analysis method involved in the embodiments of the present application can be implemented by a terminal device or a server, and the present application does not impose any special restrictions on this. For the convenience of understanding and description, the following embodiments are described in detail by taking a server as an example.

[0029] It should be noted that the server may be a single device or a system consisting of multiple devices, that is, a distributed server, and this application does not make any specific limitation on this.

[0030] like Figure 1 As shown, the embodiment of the present application provides a campus network quality evaluation method, including:

[0031] S101: Acquire physical resource usage information and device status information of a switch device through a management information base, and generate a physical resource usage score corresponding to the switch device according to the physical resource usage information and the device status information.

[0032] In one embodiment, when generating a physical resource usage score, the physical resource usage information of the switch device must first be obtained. The physical resource usage information here includes at least information such as the processor usage, memory usage, device temperature, fan speed, power status, etc. of the switch device. Then, the excess value of each physical resource usage information of the switch device compared to the preset physical threshold is determined. For example, the preset physical threshold for device temperature is 60 degrees. If the device temperature of a certain switch device reaches 63 degrees, the excess value is 3 degrees. Then, based on the size of the excess value and the number of switch devices, the physical resource usage score of the switch device in the target park is determined. For example, taking the full score as the total number of switch devices of 100 as an example, the number of switch devices that exceed the preset physical threshold can be directly used as the deduction value. If 30 devices exceed the preset physical threshold from a certain indicator or multiple physical indicators, the physical resource usage score is 70 points.

[0033] S102: Read virtual resource usage information of the switch device through a simple network management protocol channel, and generate a virtual resource usage score of the switch device according to the virtual resource usage information.

[0034] In one embodiment, when determining the virtual resource usage score, firstly, the virtual resource usage information of the switch device is obtained, where the virtual resource usage information at least includes the number of virtual LANs and the number of LAN addresses of the switch device, and then it is determined whether the number of virtual LANs and the number of LAN addresses corresponding to the switch device exceed the preset virtual threshold. If exceeded, the virtual resource usage score is determined according to the number of switch devices exceeding the preset virtual threshold. That is, the virtual device is equal to the total score minus the deduction value of the switch device regarding the number of virtual LANs and the number of LAN addresses, and the deduction value here is related to the number of switch devices exceeding the preset virtual threshold.

[0035] S103: Receive alarm information from the switch device, and generate a device alarm score according to the alarm information and preset rules.

[0036] In one example, when a switch device fails, an alarm is sent to the ELK server. At this time, the software-defined network controller receives alarm information from the switch device, where the alarm information at least includes the fault description and the fault time. Then, according to the fault description and the fault time, as well as the preset alarm rules, the fault impact level corresponding to the alarm information is determined, and the device alarm score is determined according to the fault impact level corresponding to the switch device. For example, the total score of the device alarm is 100 points, and the device alarm level is zero to six levels, where the level deduction value corresponding to each alarm information can be: 10 points for level zero, 5 points for level one and two, and 1 point for level three.

[0037] S104: Obtain port traffic information of the switch device through the ELK server, and generate a network traffic score according to the port traffic information.

[0038] S105: Generate a communication quality score by acquiring packet loss information of the switch device.

[0039] In one embodiment, when determining the network traffic score, it is necessary to determine the number of traffic monitoring lost devices in the switch device based on the port traffic information, and then determine the network traffic score based on the number of traffic monitoring lost devices. Specifically, the network traffic score is related to the number of remaining devices obtained by subtracting the number of monitoring lost devices from the total number of devices.

[0040] When calculating the communication quality score, it is necessary to determine the number of packet loss nodes in the switch device based on the packet loss information, and then generate the communication quality score based on the number of packet loss nodes. Specifically, the communication quality score is related to the number of remaining nodes obtained by subtracting the number of packet loss nodes from the total number of nodes.

[0041] S106: Generate a network quality score for the target campus according to the physical resource usage score, the device alarm score, the network traffic score, the device virtual resource score, and the communication quality score.

[0042] In one embodiment, when generating the network quality score of the target park, the preset weight coefficients corresponding to the physical resource usage score, the device alarm score, the network traffic score, the device virtual resource score, and the communication quality score must be determined first, that is, in the network quality score, whichever of these intermediate scores is more important, then its preset weight coefficient is larger. Then, according to the preset weight coefficients, the sum of the scores of the physical resource usage score, the device alarm score, the network traffic score, the device virtual resource score, and the communication quality score is determined, and then the score ratio of the sum of the scores to the total score of the physical resource usage score, the device alarm score, the network traffic score, the device virtual resource score, and the communication quality score is determined. The total score here refers to the sum of the total scores of these intermediate scores, and then the network quality score can be determined by the score ratio.

[0043] like Figure 2As shown in the figure, before obtaining various types of information, the software-defined network controller needs to access the switch device in the campus network environment, and the device has initialized the configuration account password and SNMP information. In addition, all devices are bound to monitoring items on the software-defined network controller page. The software-defined network controller obtains information such as CPU, memory, temperature, power supply, disk, etc. through the device management information library at regular intervals. Then the software-defined network controller regularly accesses the device through the simple network management protocol channel to query the device virtual resource usage information. The software-defined network controller monitors the import and export traffic of each port of the device and the alarm information reported on the device through the open source tools Elasticsearch, Logstash, and Kibana. Users can view the panoramic monitoring of the device on the software-defined network controller interaction page, which mainly includes the device physical resource usage information, virtual resource usage information, device alarm information, device port traffic information, and packet loss information. Figure 2 The sdn controller is the software defined network controller, and the elk server refers to the open source tools Elasticsearch, Logstash, and Kibana. Access devices, aggregation devices, core devices, etc. are all switch devices.

[0044] In one embodiment, after the network quality score of the target campus is generated, the physical resource usage score, the device alarm score, the network traffic score, the device virtual resource score, the communication quality score, and the network quality score can also be summarized; then, based on the physical resource usage score, the device alarm score, the network traffic score, the device virtual resource score, and the communication quality score, the network quality improvement suggestions for the target campus are generated. For example, if the physical resource usage score is low, the score can be improved by improving the switch equipment. Then, the network quality improvement suggestions and the score summary are sent to the network responsible person.

[0045] In one embodiment, in order to prevent abnormal operation of the device and thus damage to the device, the device status of the switch device can be monitored within a short period of time. At this time, the physical state change value of the target switch device in a specific state within the first preset time can be determined first, where the target switch device refers to the switch device that needs to be monitored. The specific state refers to no change in the working state within a period of time, such as power on and power off. If the physical state change value exceeds the preset warning threshold, an alarm is sent to the network responsible person to prevent the switch device from malfunctioning.
