[0055] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0056] The link bandwidth quality monitoring method provided in the embodiment of the present application can be applied to the same-region software-defined wide area network (SDWAN) networking scenario as shown in Figure 1, or can also be applied to the cross-region SDWAN networking scenario as shown in Figure 2. Figure 1 is a same-region branch interconnection scenario, where two branch networks at the site are connected to the edge gateway (POP) of the local domain through the customer premise equipment (Customer Premise Equipment, CPE), and interconnection is achieved through POP forwarding. When the CPE accesses the POP, virtual IPsec interfaces will be established on the CPE and POP respectively. The two interfaces form an overlay link through IPsec negotiation. The traffic accessing the CPE is encrypted through the IPsec port and forwarded to the POP through the overlay link. The traffic received by the POP will also be encrypted through the corresponding IPsec port and forwarded to the corresponding CPE through the overlay link. Figure 2 shows a cross-regional branch interconnection scenario, where sites in different regions are connected to the edge gateway POP in their respective regions through CPEs, and the link in the CPE-POP segment is also an IPsec virtual link; the POPs in the two locations mainly form an overlay link by creating a vxlan tunnel to achieve cross-regional traffic forwarding. When the traffic is from A to B, it is first encrypted by the CPE device in A and then transmitted to the POP in A. The POP in A sends the traffic to the POP in B through a vxlan tunnel, and then the POP in B encrypts the traffic and transmits it to the CPE in B through IPsec, and then forwards it to the corresponding target address in B, achieving cross-regional traffic interconnection between A and B. In addition, it should be noted that the link bandwidth quality monitoring method provided in the embodiment of the present application is not only applicable to SDWAN networking, but also to other cloud network overlay networking scenarios, such as cross-cloud resource pool networking. FIG3 is an application environment diagram of link bandwidth quality monitoring provided by an embodiment of the present application. In this application environment, the control and alarm platform can be implemented through a server or a server cluster. The monitoring component is composed of monitoring devices on node devices in the network. Each monitoring device can be deployed on each node device in the network, such as CPE and POP, etc. The main function is to monitor and count the sending and receiving message rates of the corresponding interfaces of the networking overlay links in real time, and transmit them to the control and alarm platform. The control and alarm platform is the core component of the system, and its main functions include three points: first, configure the networking information and alarm conditions that need to be monitored and analyze the configuration information, and send the overlay link interface information that needs to be monitored in real time to the monitoring devices of the CPE and POP devices; second, analyze the monitoring data transmitted by the configured monitoring device to obtain the bandwidth quality of each link segment; third, determine whether to send alarm information to the alarm recipient based on the configured monitoring conditions and the current bandwidth quality of each link segment.

[0057] In an exemplary embodiment, as shown in FIG4 , a link quality monitoring method is provided, which is described by taking the method applied to the management and control alarm platform in FIG3 as an example, including:

[0058] S201, determining device information of a link to be monitored according to networking information; the device information includes information of node devices in the link to be monitored and information of virtual link interfaces corresponding to the node devices.

[0059] First, it should be noted that the networking in this embodiment can be SDWAN networking, or other cloud network overlay networking, etc. This embodiment does not limit the networking type of the application. Optionally, in this embodiment, the networking information can be parsed to analyze the node devices and related virtual link interfaces involved in the networking. For example, when the networking is SDWAN networking, the networking may involve CPE devices, POP devices, virtual link interfaces on CPE devices, and virtual link interfaces on POP devices. When the networking is overlay networking, the networking may involve cloud hosts and virtual link interfaces on cloud hosts. Further, after determining the node devices involved in the networking, the control and alarm platform can send monitoring instructions to the node devices in the networking, and the monitoring instructions may include the virtual link interface information corresponding to each node device. The monitoring instructions can be used to instruct each node device in the networking to monitor the message transmission rate of the corresponding virtual link interface, and upload the collected message transmission rate of the corresponding virtual link interface to the control and alarm platform according to the preset time interval.

[0060] Optionally, in this embodiment, the virtual links included in the networking can be determined based on the node devices involved in the networking, the connection relationship between the node devices, and the flow direction of the message, and then the link to be monitored can be determined from the virtual links included in the networking. Further, the device information of the link to be monitored can be determined based on the networking information, that is, the information of the node devices included in the link to be monitored and the information of the virtual link interface corresponding to the node devices can be determined.

[0061] S202: Based on the device information, obtain a message transmission rate of a virtual link interface corresponding to the node device within a preset time period.

[0062] Optionally, in this embodiment, after determining the node devices in the link to be monitored and the virtual link interface information corresponding to the node devices, the message transmission rates of the corresponding virtual link interfaces collected by the node devices in the link to be monitored within the preset time period can be accumulated and counted to obtain the message transmission rate of the virtual link interface corresponding to the node devices within the preset time period. Exemplarily, assuming that the networking in this embodiment is the cross-regional networking shown in FIG5, the node devices involved in the networking are CPE1, POP1, CPE2, and POP2, and the virtual link interfaces involved are ipsec100 on CPE1, ipsec100 and vxlan100 on POP1, vxlan100 and ipsec100 on POP2, and ipsec100 on CPE2. Taking the link to be monitored as the CPE1-POP1 link as an example, it is necessary to obtain the message transmission rate of the ipsec100 interface of CPE1 within the preset time period, and the message transmission rate of the ipsec100 interface of POP1.

[0063] S203: Obtain a bandwidth quality monitoring result of the link to be monitored according to the message transmission rate.

[0064] Optionally, in this embodiment, the message transmission rate of the virtual link interface corresponding to the node device in the link to be monitored can be compared with a preset threshold. If the message transmission rate of the virtual link interface corresponding to each node device in the link to be monitored is greater than or equal to the preset threshold, the bandwidth quality monitoring result of the link to be monitored is determined to be normal; if the message transmission rate of the virtual link interface corresponding to a node device in the link to be monitored is less than the preset threshold, the bandwidth quality monitoring result of the link to be monitored is determined to be abnormal.

[0065] In the above-mentioned link quality monitoring method, since the device information of the link to be monitored can be determined according to the networking information, wherein the device information of the link to be monitored includes the information of the node device in the link to be monitored and the information of the virtual link interface corresponding to the node device, the message transmission rate of the virtual link interface corresponding to the node device in the link to be monitored within a preset time period can be obtained based on the device information of the link to be monitored, and the bandwidth quality of the link to be monitored is monitored according to the message transmission rate of the virtual link interface. There is no need to introduce an additional interactive process to obtain the bandwidth information of the link to be monitored and monitor the bandwidth quality. The bandwidth quality monitoring result of the link to be monitored can be quickly obtained, thereby improving the monitoring efficiency of the link quality. In addition, based on the bandwidth quality monitoring result of the link to be monitored, the link where the packet loss occurs can be quickly located, so that relevant alarm information can be sent to the operation and maintenance personnel in time, so that the operation and maintenance personnel can obtain the link fault location in time for troubleshooting and recovery, thereby improving the networking operation and maintenance efficiency.

[0066] In this embodiment, the detailed process of obtaining the bandwidth quality monitoring result of the link to be monitored according to the message transmission rate of the virtual link interface corresponding to the node device is explained. In an exemplary embodiment, as shown in FIG6 , the above S203 includes:

[0067] S301, determining a message sending rate of a sending port and a message receiving rate of a receiving port of a link to be monitored within a preset time period according to a message transmission rate.

[0068] In this embodiment, the sending port and receiving port in the link to be monitored can be determined based on the device information of the link to be monitored, and then the message sending rate of the sending port and the message receiving rate of the receiving port of the link to be monitored within the preset time period can be determined according to the message transmission rate of the virtual link interface corresponding to the node device of the link to be monitored. Continuing to use the networking example in the above-mentioned Figure 5 as an example for explanation, taking the link to be monitored as the CPE1-POP1 link as an example, the sending port is the virtual link interface on CPE1, and the receiving port is the virtual link interface on POP1. The message sending rate can be obtained by obtaining the message transmission rate of the virtual link interface on CPE1, and the message receiving rate can be obtained by obtaining the message transmission rate of the virtual link interface on POP1.

[0069] S302: Obtain a bandwidth quality monitoring result of the link to be monitored according to a message sending rate and a message receiving rate.

[0070] Optionally, in this embodiment, the ratio of the message receiving rate to the message sending rate can be obtained, and the ratio of the message sending rate to the message receiving rate can be compared with a preset threshold to obtain the bandwidth quality monitoring result of the link to be monitored. For example, if the ratio of the message receiving rate to the message sending rate is less than 1, it can be determined that the bandwidth quality monitoring result of the link to be monitored is abnormal.

[0071] In this embodiment, according to the message transmission rate of the virtual link interface corresponding to the node device of the link to be monitored, the message sending rate of the sending port and the message receiving rate of the receiving port of the link to be monitored within a preset time period can be quickly determined, so that the bandwidth quality monitoring result of the link to be monitored can be quickly obtained according to the message sending rate and the message receiving rate, thereby ensuring the efficiency of obtaining the bandwidth quality monitoring result of the link to be monitored and being able to monitor the bandwidth quality of the link to be monitored in a timely manner.

[0072] In some scenarios, the bandwidth quality monitoring result of the link to be monitored can be obtained by obtaining the bandwidth quality value of the link to be monitored. In one embodiment, as shown in FIG7 , the above S302 includes:

[0073] S401: Obtain a bandwidth quality value of a link to be monitored according to a message sending rate and a message receiving rate.

[0074] Optionally, in this embodiment, the ratio of the message receiving rate to the message sending rate can be determined as the bandwidth quality value of the link to be monitored. Alternatively, the difference between the message sending rate and the message receiving rate can be obtained, and the bandwidth quality value of the link to be monitored can be determined based on the difference and the ratio of the message sending rate. For example, the absolute value of the difference and the ratio of the message sending rate can be determined as the bandwidth quality value of the link to be monitored. For example, assuming that the message sending rate of the sending port of the link to be monitored within a preset time period is , the message receiving rate of the receiving port is , the bandwidth quality value of the link to be monitored is , then according to the formula Determine the bandwidth quality value of the link to be monitored.

[0075] S402: If the bandwidth quality value is less than a preset threshold, determine that the bandwidth quality monitoring result is abnormal.

[0076] Optionally, in this embodiment, the bandwidth quality value of the link to be monitored can be compared with a preset threshold value. If the bandwidth quality value is less than the preset threshold value, it means that there may be packet loss in the link to be monitored and the bandwidth quality is reduced, and the bandwidth quality monitoring result of the link to be monitored can be determined to be abnormal; on the contrary, if the bandwidth quality is greater than or equal to the preset threshold value, it means that the bandwidth quality of the link to be monitored is normal, and the bandwidth quality monitoring result of the link to be monitored can be determined to be normal. As an optional implementation method, when it is determined that the bandwidth quality monitoring result of the link to be monitored is abnormal, an alarm message can be generated, and the alarm message can be sent to the terminal corresponding to the alarm object in accordance with a preset alarm method, such as SMS, email, etc., wherein the alarm object can be an operation and maintenance personnel who repairs the networked link, so that the operation and maintenance personnel can obtain the link fault location in time and conduct troubleshooting and recovery, thereby improving the operation and maintenance efficiency of the network. It can be understood that the preset threshold in this embodiment can be an empirical value determined by the control and alarm platform based on historical data; or, the preset threshold can also be determined by the control and alarm platform based on the message transmission rate of the virtual link interface corresponding to the node device of the link to be monitored. For example, the average value of the message transmission rate of the virtual link interface corresponding to all node devices of the link to be monitored can be determined as the preset threshold, or the difference between the maximum and minimum values ​​of the message transmission rate of the virtual link interface corresponding to the node device of the link to be detected can be determined as the preset threshold. This embodiment does not limit the method for determining the preset threshold.

[0077] In this embodiment, the process of obtaining the bandwidth quality value of the link to be monitored based on the message sending rate and the message receiving rate of the link to be monitored is relatively simple, and the bandwidth quality value of the link to be monitored can be quickly obtained. Therefore, when the bandwidth quality value of the link to be monitored is less than a preset threshold, it can be quickly determined that the bandwidth quality monitoring result of the link to be monitored is abnormal, thereby improving the efficiency of determining the bandwidth quality monitoring result of the link to be monitored.

[0078] In this embodiment, the specific process of obtaining the message transmission rate of the virtual link interface corresponding to the node device within the preset time period is explained. In one embodiment, as shown in FIG8 , the above S202 includes:

[0079] S501, sending a monitoring instruction to a node device; the monitoring instruction is used to instruct the node device to collect the message transmission rate of the virtual link interface corresponding to the node device.

[0080] In this embodiment, after determining the information of the node device in the link to be monitored and the information of the virtual link interface corresponding to the node device, a monitoring instruction can be sent to the node device, and the monitoring instruction can include the information of the virtual link interface corresponding to the node device. Through the monitoring instruction, the node device can be instructed to collect the message transmission rate of the corresponding virtual link interface. Continuing to use the networking example in Figure 5 as an example, a monitoring instruction can be sent to CPE1 in the link to be monitored, and the monitoring instruction includes the information of the virtual link interface ipsec100 interface corresponding to CPE1. Through the monitoring instruction, CPE1 can be instructed to collect the message transmission rate of the corresponding ipsec100 interface. The monitoring instruction is also sent to other node devices in the networking in the same way, and this embodiment will not be described one by one here.

[0081] S502: Determine the message transmission rate of the virtual link interface corresponding to the node device within a preset time period according to the message transmission rate of the corresponding virtual link interface reported by the node device.

[0082] Optionally, in this embodiment, after the node device collects the message transmission rate of the corresponding virtual link interface, it can send the message transmission rate of the virtual link interface to the management and alarm platform at a preset time interval. After the management and alarm platform receives the message transmission rate of the corresponding virtual link interface reported by the node device in the link to be monitored, it can perform statistics on the message transmission rate of the corresponding virtual link interface collected by the node device within the preset time period to determine the message transmission rate of the virtual link interface corresponding to the node device in the link to be monitored within the preset time period.

[0083] In this embodiment, by sending a monitoring instruction to the node device in the link to be monitored, the node can be instructed to collect the message transmission rate of the corresponding virtual link interface through the monitoring instruction, so that the management and control alarm platform can quickly determine the message transmission rate of the virtual link interface corresponding to the node device within a preset time period based on the message transmission rate of the corresponding virtual link interface reported by the node device in the link to be monitored, thereby improving the efficiency of determining the message transmission rate of the virtual link interface corresponding to the node device in the link to be monitored.
