Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of a network link determining method provided by the present invention, and as shown in fig. 1, an execution main body of the network link determining method may be an electronic device, for example, a Customer Premises Equipment (CPE) or the like. The method comprises the following steps:
step 101, acquiring first network detection information;
specifically, in order to achieve high availability of wireless communication, a Virtual Private Network (VPN) link in a wireless communication Network may be detected to obtain first Network detection information, where the first Network detection information may include communication status information of a primary VPN Network link, and further, whether the primary VPN Network link is abnormal may be determined based on the first Network detection information.
Alternatively, the active VPN network link may be probed by executing a network diagnostic tool (Packet Internet Groper, ping) command, and the probing period may be determined according to an actual network service requirement.
For example, the active VPN network link may be subjected to real-time ping packet monitoring by executing an fping command, where the fping command may include: the destination IP address of the ping packet, the number of times each destination is ping (e.g., 3), the ping packet interval for the same destination (e.g., 1000 milliseconds), or the timeout time for a single destination (e.g., 500 milliseconds), etc.
102, determining that the primary VPN network link has abnormity based on the first network detection information;
specifically, after the first network probe information is acquired, whether the primary VPN network link is abnormal or not may be determined according to the communication condition information of the primary VPN network link, and when the communication condition information of the primary VPN network link satisfies a first preset abnormality determination condition, it may be determined that the primary VPN network link is abnormal.
For example, the first network probe information may include a communication packet loss rate of the primary VPN network link; the first preset abnormal determination condition may be satisfied, where a packet loss rate of the primary VPN network link is greater than or equal to a first preset packet loss rate threshold (e.g., the threshold is 100%).
103, determining a standby VPN network link as a target network link in two or more VPN links, where the target network link is used for network communication between the convergence side communication device and the access side communication device;
the two or more VPN links correspond to different wireless physical network links, and the two or more VPN links include the primary VPN network link and one or more standby VPN network links, and the wireless physical network link corresponding to the primary VPN network link is a fifth Generation Mobile Communication technology (5 th Generation Mobile Communication technology,5 g) physical network link.
Specifically, after it is determined that the primary VPN network link is abnormal, one standby VPN network link may be determined as a target network link in two or more VPN links, and then the target network link may continue to carry the communication service between the aggregation side communication device and the access side communication device, so as to avoid interruption of network communication due to the abnormality of the primary VPN network link.
Optionally, two or more VPN links may be provided between the convergence side communication device and the access side communication device, and the two or more VPN links correspond to different wireless physical network links respectively.
For example, there may be two VPN links between the aggregation side communication device and the access side communication device, where a wireless physical network link corresponding to one VPN link may be a 5G physical network link a, and a wireless physical network link corresponding to the other VPN link may be a 5G physical network link B, where the 5G physical network link a and the 5G physical network link B are not the same link.
For example, two VPN links may be provided between the aggregation-side communication device and the access-side communication device, where a wireless physical network link corresponding to one VPN link may be a 5G physical network link a, and a wireless physical network link corresponding to the other VPN link may be a WIFI physical network link C, where the 5G physical network link a and the WIFI physical network link C are not the same link.
It can be understood that, when an abnormal VPN link occurs, a communication abnormality may also occur in the wireless physical network link corresponding to the abnormal VPN link, but since two or more VPN links respectively correspond to different wireless physical network links, even if a communication abnormality occurs in the wireless physical network link corresponding to the abnormal VPN link, the communication of other VPN links will not be affected.
Optionally, the convergence side communication device is communicatively connected to a service device of the convergence side, and the access side communication device is communicatively connected to a service device of the access side, where the service device of the convergence side may be a server bearing a specific service, and the service device of the access side may be a front-end device of the specific service.
For example, the aggregation side communication device may be an aggregation side CPE device, and the access side communication device may be an access side CPE device.
It can be understood that two different wireless physical network links may exist between the convergence side communication device and the access side communication device, both the convergence side communication device and the access side communication device support VPN creation, and after the convergence side communication device and the access side communication device access the two different wireless physical network links, a VPN link may be created, so as to ping Internet Protocol (IP) addresses of opposite ends between the convergence side communication device and the access side communication device, respectively, and if there is no packet loss in a ping packet, it may be determined that the VPN link service is normal.
It can be understood that the two or more VPN links include the active VPN network link and one or more backup VPN network links, and in a case that the active VPN network link is abnormal, one of the one or more backup VPN network links may be determined as a target network link, so as to ensure normal communication between the convergence side communication device and the access side communication device.
The network link determining method provided by the invention can judge whether the main VPN network link is abnormal or not by acquiring the first network detection information, can determine one standby VPN network link as a target network link from two or more than two VPN links under the condition of determining that the main VPN network link is abnormal, can ensure that the communication between the communication equipment at the convergence side and the communication equipment at the access side is not interrupted by switching between the main VPN network link and the standby VPN network link, and can realize the high availability of wireless communication.
Optionally, the wireless physical network links corresponding to the one or more backup VPN network links include one or more of the following links:
a 5G physical network link;
a WIFI physical network link.
Optionally, there may be only one standby VPN network link, where the wireless physical network link corresponding to the one standby VPN network link may be a 5G physical network link, and the 5G physical network link corresponding to the standby VPN network link is not the same as the 5G physical network link corresponding to the active VPN network link.
Optionally, there may be only one backup VPN network link, and the wireless physical network link corresponding to the one backup VPN network link may be a WIFI physical network link.
Optionally, there may be two standby VPN network links, where a wireless physical network link corresponding to one standby VPN network link may be a 5G physical network link, and a wireless physical network link corresponding to the other standby VPN network link may be a WIFI physical network link.
Therefore, two different wireless physical network links may exist between the convergence side communication device and the access side communication device, and when a certain VPN link is abnormal, the wireless physical network link corresponding to the abnormal VPN link may also have communication abnormality.
Optionally, the determining, in two or more VPN links, one standby VPN network link as the target network link includes:
determining the first standby VPN network link as the target network link when the one or more standby VPN network links only include a first standby VPN network link and a wireless physical network link corresponding to the first standby VPN network link is a 5G physical network link;
or determining the second standby VPN network link as the target network link when the one or more standby VPN network links only include a second standby VPN network link and the wireless physical network link corresponding to the second standby VPN network link is a WIFI physical network link.
Specifically, after it is determined that the active VPN network link is abnormal, if only one backup VPN network link is present, that is, the first backup VPN network link, and the wireless physical network link corresponding to the first backup VPN network link is a 5G physical network link, it may be determined that the first backup VPN network link is used as a target network link, and then the target network link may continue to carry the communication service between the aggregation side communication device and the access side communication device, so as to avoid network communication interruption caused by the abnormality of the active VPN network link.
Specifically, after it is determined that the primary VPN network link is abnormal, if only one backup VPN network link is present, that is, the second backup VPN network link, and the wireless physical network link corresponding to the second backup VPN network link is a WIFI physical network link, it may be determined that the second backup VPN network link is used as a target network link, and then the target network link may continue to carry the communication service between the aggregation-side communication device and the access-side communication device, so as to avoid network communication interruption caused by the abnormality of the primary VPN network link.
Optionally, the determining, in two or more VPN links, one standby VPN network link as the target network link includes:
determining a third backup VPN network link as the target network link when the one or more backup VPN network links include two backup VPN network links;
the third backup VPN network link is a link with higher communication quality in the two backup VPN network links.
Specifically, after it is determined that the primary VPN network link is abnormal, if two backup VPN network links exist, one of the two backup VPN network links with higher communication quality may be determined to serve as a third backup VPN network link, and then the third backup VPN network link may be determined to serve as a target network link, so that the communication service between the convergence side communication device and the access side communication device may be continuously carried through the target network link, and network communication interruption caused by the abnormality of the primary VPN network link is avoided.
Optionally, after determining one backup VPN network link as the target network link, the method further includes:
acquiring second network detection information of the primary VPN network link;
determining that the link of the primary VPN network is recovered to be normal based on the second network detection information;
and determining the primary VPN network link as the target network link.
Optionally, the active VPN network link may be detected to obtain second network detection information, where the second network detection information may include communication status information of the active VPN network link, and further, based on the second network detection information, whether the active VPN network link is abnormal may be determined.
Optionally, the active VPN network link may be probed by executing the fping command to obtain the second network probing information, and the probing period may be determined according to an actual network service requirement.
For example, the real-time ping packet monitoring may be performed on the active VPN network link by executing an fping command, where the fping command may include: the destination IP address of the ping packet, the number of times each destination is ping (e.g., 3), the ping packet interval for the same destination (e.g., 1000 milliseconds), or the timeout time for a single destination (e.g., 500 milliseconds), etc.
Optionally, after the second network probe information is acquired, whether the primary VPN network link is abnormal may be determined according to the communication condition information of the primary VPN network link, and when the communication condition information of the primary VPN network link satisfies a second preset abnormal determination condition, it may be determined that the primary VPN network link is recovered to be normal.
For example, the second network detection information may include a communication packet loss rate of the primary VPN network link; when the second preset abnormality determination condition is satisfied, the packet loss rate of the primary VPN network link may be smaller than or equal to a second preset packet loss rate threshold (for example, the threshold is 0%).
