[0048] First, for the convenience of understanding, the terms involved in the writing process of the present invention are introduced as follows:

[0049] 5G network: The fifth generation mobile communication technology (5th Generation Mobile Communication Technology, referred to as 5G) is a new generation of broadband mobile communication technology with high speed, low latency and large connection characteristics. It is the network infrastructure for realizing the interconnection of man, machine and things. The International Telecommunication Union (ITU) has defined three major application scenarios for 5G, namely enhanced mobile broadband (eMBB), ultra-high reliability and low latency communication (uRLLC) and massive machine type communication (mMTC). Enhanced mobile broadband (eMBB) is mainly aimed at the explosive growth of mobile Internet traffic, providing mobile Internet users with a more extreme application experience; ultra-high reliability and low latency communication (uRLLC) is mainly aimed at vertical industry application needs with extremely high requirements for latency and reliability, such as industrial control, telemedicine, and autonomous driving; massive machine type communication (mMTC) is mainly aimed at smart cities, smart homes, environmental monitoring and other applications with sensing and data collection as the goal. In order to meet the diverse application scenario requirements of 5G, the key performance indicators of 5G are more diversified. ITU has defined eight key performance indicators for 5G, among which high speed, low latency and large connections have become the most prominent features of 5G. The user experience rate reaches 1Gbps, the latency is as low as 1ms, and the user connection capacity reaches 1 million connections / square kilometer.

[0050] Bridge: A two-port Layer 2 network device that forwards frames. A bridge, also called a bridge, is a storage / forwarding device that connects two local area networks. It can divide a large LAN into multiple segments, or interconnect more than two LANs into a logical LAN, so that all users on the LAN can access the server.

[0051] The most common way to extend a LAN is to use a bridge. The simplest bridge has two ports, and more complex bridges can have more ports. Each port of the bridge is connected to a network segment.

[0052] ebtables: Linux kernel bridge firewall tool; specifically, Ebtables is a Linux kernel firewall configuration tool, which is specially used to control and filter the traffic of the bridge interface in the Linux system kernel, and can also control the takeover of the ARP protocol by the bridge interface;

[0053] VXLAN (Virtual eXtensible Local Area Network): used to achieve Layer 2 network expansion that penetrates Layer 3 networks; in addition, VXLAN technology is a large Layer 2 virtual network technology. The main principle is to introduce an outer tunnel in UDP format as the data link layer, and the original data message content is transmitted as the tunnel payload. Since the outer layer uses UDP as the transmission method, the payload data can be easily transmitted in the Layer 2 and Layer 3 networks.

[0054] The present application provides a communication link protection method, which can be applied to Figure 1 In the application environment shown, Figure 1 is a schematic diagram of an application environment of a communication link protection method according to an embodiment of the present application, such as Figure 1 As shown, the first 5G device 110 and the client 130 are connected by wired communication, and the second 5G device 120 and the server 140 are connected by wired communication. Based on the 5G network, the first 5G device 110 and the second 5G device 120 establish a primary link; when an abnormality is detected in the primary link, the communication link between the first 5G device 110 and the second 5G device 120 is switched from the primary link to the backup link, so that the client 130 and the server 140 communicate through the backup link between the first 5G device 110 and the second 5G device 120 to ensure the stable operation of the entire communication link. Among them, the backup link is a wired connection link connected between the first 5G device 110 and the second 5G device 120. In addition, the client 130 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers and portable wearable devices, and the server 140 can be implemented by an independent server 140 or a server 140 cluster composed of multiple servers 140.

[0055] This application proposes a communication link protection method, which is applied to 5G networks. Figure 2 is a first flow chart of a communication link protection method according to an embodiment of the present application, such as Figure 2 As shown, the method comprises the following steps:

[0056] Step S201, communicating with the client 130 through the first 5G device 110, and communicating with the server 140 through the second 5G device 120;

[0057] Step S202, based on the 5G network, the first 5G device 110 and the second 5G device 120 establish a primary link; that is, the communication link formed between the client 130 and the server 140 through the 5G network is used as the primary link to provide a dedicated line service;

[0058] Step S203, when an abnormality is detected in the primary link, the communication link between the first 5G device 110 and the second 5G device 120 is switched from the primary link to the backup link, so that the client 130 and the server 140 communicate through the backup link between the first 5G device 110 and the second 5G device 120, wherein the backup link is a wired connection link connected between the first 5G device 110 and the second 5G device 120. Those skilled in the art can monitor the communication status of the primary link through some existing software, programs or algorithms, that is, as long as the monitoring purpose can be achieved, it is not specifically limited here;

[0059] Through the above steps S201 to S203, compared with the previous situation where the 5G network number is unstable or the signal is abnormal, which causes the main link to be abnormal and the entire system is paralyzed, when the main link is detected to be abnormal, the communication link between the first 5G device 110 and the second 5G device 120 is switched from the main link to the backup link in this embodiment, so that the client 130 and the server 140 can communicate normally through the backup link between the first 5G device 110 and the second 5G device 120. In this way, not only the stability of the communication of the entire system is improved, but also a good experience is brought to the user, and the problem that the relevant technology cannot exclude the situation that the 5G signal is unstable or the 5G network is interrupted due to an emergency, resulting in the communication system being in a paralyzed state, thereby seriously affecting the user experience is solved.

[0060] Figure 3 is a first schematic diagram of an overall structure of a communication link according to an embodiment of the present application, Figure 4 is a second schematic diagram of the overall structure of a communication link according to an embodiment of the present application, referring to Figure 3 and Figure 4 In some embodiments, establishing a primary link between the first 5G device 110 and the second 5G device 120 based on the 5G network includes the following steps:

[0061] Establish a first VXLAN tunnel link through the first 5G device 110 and the second 5G device 120;

[0062] The first VXLAN tunnel link is used as the primary link, so that the client 130 and the server 140 communicate through the primary link between the first 5G device 110 and the second 5G device 120, wherein the first VXLAN tunnel link is established by the communication connection between the first wireless port 310 of the first 5G device 110 and the first wireless port 311 of the second 5G device 120. Figure 3 and Figure 4In this embodiment, the name of the first wireless port 310 of the first 5G device 110 is lte1, and the name of the first wireless port 311 of the second 5G device 120 is lte2. Of course, in other embodiments, the interface names of the above wireless ports can be set to other names, which are not specifically limited here;

[0063] In some embodiments, after establishing the first VXLAN tunnel link through the first 5G device 110 and the second 5G device 120, the method further includes the following steps:

[0064] Bridge the second wired port 330 of the first 5G device 110 and the first virtual interface 3100 to generate a first bridge interface 3101;

[0065] A first large Layer 2 link is formed based on the second wired port 330 of the first 5G device 110, the first virtual interface 3100, and the first bridge interface 3101;

[0066] While bridging the second wired port 330 and the first virtual interface 3100 of the first 5G device 110, the second wired port 331 and the second virtual interface 3110 of the second 5G device 120 are bridged to generate a second bridge interface 3111; Figure 3 and Figure 4 The name of the first bridge interface 3101 is br-vxlan-lte1-lan1, and the name of the second bridge interface 3111 is br-vxlan-lte2-lan2. Of course, in other embodiments, the names of the above bridge interfaces can be set to other names, which are not specifically limited here.

[0067] A second large Layer 2 link is formed based on the second wired port 331, the second virtual interface 3110 and the second bridge interface 3111 of the second 5G device 120, so that the client 130 and the server 140 establish a communication connection based on the first large Layer 2 link and the second large Layer 2 link, wherein the first virtual interface 3100 is a virtual interface connected to the first wireless port 310 of the first 5G device 110 generated when the first VXLAN tunnel link is established, and the second virtual interface 3110 is a virtual interface connected to the first wireless port 311 of the second 5G device 120 generated when the first VXLAN tunnel link is established. Figure 3 and Figure 4 In this embodiment, the name of the first virtual interface 3100 is vxlan-lte1, and the name of the second virtual interface 3110 is vxlan-lte2. Of course, in other embodiments, the names of the above virtual interfaces can be set to other names, which are not specifically limited here;

[0068] To facilitate monitoring, in some embodiments, when the first VXLAN tunnel link is used as the primary link, the step of monitoring the working status of the primary link includes the following steps:

[0069] The first virtual interface 3100 and the second virtual interface 3110 are respectively configured with IP addresses of the same network segment; for example, the first virtual interface 3100 and the second virtual interface 3110 are respectively configured with IP addresses of 1.1.1.1 / 24 and 1.1.1.2 / 24 of the same network segment;

[0070] Based on the ebtables tool, the kernel is configured to allow the ARP message to bypass the first bridge interface 3101 and the second bridge interface 3111 respectively, and the ping command is used to confirm whether the first virtual interface 3100 and the second virtual interface 3110 are connected. If so, the first VXLAN tunnel link works normally, and if not, the first VXLAN tunnel works abnormally, wherein the ARP message is a message sent by the client 130 based on the ARP protocol. That is, if the ping is successful, it is considered that the first VXLAN tunnel link works normally, otherwise, it is considered that the first VXLAN tunnel link works abnormally. Since those skilled in the art know how to use the ping command, they will not be described one by one here.

[0071] In order to prevent the entire system from being paralyzed due to an abnormality in the primary link, in some embodiments, while the primary link is established between the first 5G device 110 and the second 5G device 120 based on the 5G network, the method further includes the following steps:

[0072] Establish a second VXLAN tunnel link through the first 5G device 110 and the second 5G device 120;

[0073] The second VXLAN tunnel link is used as a backup link. In this way, even if an abnormality occurs in the primary link, the client 130 and the server 140 can communicate through the backup link between the first 5G device 110 and the second 5G device 120 to ensure the stability of the communication of the entire system. The second VXLAN tunnel link is established by the communication connection between the first wired port 320 of the first 5G device 110 and the first wired port 321 of the second 5G device 120.

[0074] In order to ensure that the entire system can communicate normally, in some embodiments, when an abnormality occurs in the primary link, the communication link between the first 5G device 110 and the second 5G device 120 is switched from the primary link to the backup link, so that the client 130 and the server 140 communicate through the backup link, including the following steps:

[0075] When an abnormality is detected in the primary link, the bridge connection between the second wired port 330 of the first 5G device 110 and the first virtual interface 3100 is canceled, and the bridge connection between the second wired port 331 of the second 5G device 120 and the second virtual interface 3110 is canceled, and then the second wired port 330 of the first 5G device 110 and the third virtual interface 3200 are bridged to generate a third bridge interface 410;

[0076] A third layer 2 link is formed based on the second wired port 330 of the first 5G device 110, the third virtual interface 3200 and the third bridge interface 410;

[0077] While bridging the second wired port 330 of the first 5G device 110 and the third virtual interface 3200, the second wired port 331 of the second 5G device 120 and the fourth virtual interface 3210 are bridged to generate a fourth bridge interface 411; Figure 3 and Figure 4 The name of the third bridge interface 410 is br-vxlan-wan1-lan1, and the name of the fourth bridge interface 411 is br-vxlan-wan2-lan2. Of course, in other embodiments, the names of the above bridge interfaces can be set to other names, which are not specifically limited here.

[0078] A fourth Layer 2 link is formed based on the second wired port 331 of the second 5G device 120, the fourth virtual interface 3210 and the fourth bridge interface 411, so that the client 130 and the server 140 establish a communication connection based on the third Layer 2 link and the fourth Layer 2 link. In other words, when an abnormality occurs in the 5G network communication, it immediately switches to the wired backup link, reducing the risk of communication abnormality.

[0079] The third virtual interface 3200 is a virtual interface connected to the first wired port 320 of the first 5G device 110 generated when the second VXLAN tunnel link is established, and the fourth virtual interface 3210 is a virtual interface connected to the first wired port 321 of the second 5G device 120 generated when the second VXLAN tunnel link is established. Figure 3 and Figure 4 In this embodiment, the name of the third virtual interface 3200 is vxlan-wan1, and the name of the fourth virtual interface 3210 is vxlan-wan2. It should be noted that the above-mentioned wired ports can be implemented by Ethernet ports. Of course, other ports can also be used in other embodiments, which are not specifically limited here;

[0080] Since the transmission speed of communication data in the 5G network is faster than the transmission speed of the wired link based on the backup link, in order to improve the user experience, in some embodiments, when an abnormality is detected in the primary link, the communication link between the first 5G device 110 and the second 5G device 120 is switched from the primary link to the backup link, so that the client 130 and the server 140 communicate through the backup link, and the method further includes the following steps:

[0081] When it is monitored that the main link has resumed normal communication, the communication link between the first 5G device 110 and the second 5G device 120 is switched from the backup link to the main link, so that the client 130 and the server 140 can communicate through the main link between the first 5G device 110 and the second 5G device 120, so as to re-enable the 5G network, which not only achieves faster data transmission but also improves the user experience.

[0082] In another embodiment, switching the communication link between the first 5G device 110 and the second 5G device 120 from a backup link to a primary link includes:

[0083] When it is monitored that the first VXLAN tunnel link has resumed normal communication, the bridging between the second wired port 330 of the first 5G device 110 and the third virtual interface 3200 is canceled, and the bridging between the second wired port 331 of the second 5G device 120 and the fourth virtual interface 3210 is canceled. Then, the second wired port 330 of the first 5G device 110 and the first virtual interface 3100 are re-bridged, and the second wired port 331 of the second 5G device 120 and the second virtual interface 3110 are re-bridged.

[0084] It should be noted that the steps shown in the above process or the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0085] This embodiment also provides a system for protecting a communication link, which is used to implement the above-mentioned embodiments and preferred implementation modes, and will not be repeated hereafter.
