[0061] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0062] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0063] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0064] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0065] First combine Figure 1a The technical background of the present disclosure is further described. Figure 1a The schematic diagram of the data flow of quantum communication lines in related technologies is shown schematically. In some business scenarios in the financial industry, data transmission uses quantum communication lines to achieve real-time synchronization of data between the main and backup databases in the same city, greatly improving security. Figure 1a As shown in the figure, a special encryption device for quantum communication is introduced to realize the encryption of data transmitted on traditional lines. A special key device for quantum communication is introduced to generate a key and use a separate optical fiber link to transmit the key. A router is deployed between the central computer room network and the computer room in the same city, and the data flow of the electronic file is pulled to the router through policy routing. The quantum communication device passes the negotiated key to the VPN encryption gateway, and the VPN gateway encrypts / decrypts the data. The data flow will be encrypted after passing through the VPN gateway and sent to the peer node through the metropolitan area network transmission device. The data flow will be decrypted after passing through the peer VPN gateway and sent to the peer intranet.

[0066] In order to ensure the high availability of data transmission, it is necessary to be able to use traditional lines to complete data transmission when quantum communication and other equipment fail. Since quantum encryption equipment and secret key equipment are dedicated equipment, according to the division of operation and maintenance responsibilities, quantum-related equipment is maintained by quantum equipment maintenance units, and users cannot log in and implement monitoring. After a quantum device fails, the quantum equipment maintenance unit can only manually notify the operation and maintenance personnel, and then perform emergency operations according to the emergency manual, and the overall processing time is long. According to the traditional monitoring mode, only the internal equipment and line status of the enterprise can be monitored, and the normal operation of the entire link cannot be ensured. Multiple possible fault points need to be monitored on the quantum communication link. Any point failure will cause the quantum communication line to be unavailable, and multiple points need to be monitored uniformly. If the transmission path is manually switched after the fault is found, the recovery time is long and the business impact is large.

[0067] Based on the above technical problems, an embodiment of the present disclosure provides a communication network fault self-recovery method, which is applied to a quantum communication network, wherein the quantum communication network includes a quantum communication device, a key device, a first routing device and a second routing device, and a general routing encapsulation tunnel is pre-built between the first routing device and the second routing device. The method includes: real-time monitoring of the link status of the general routing encapsulation tunnel; determining the quantum communication link status according to the link status of the general routing encapsulation tunnel; and switching the data transmission path after determining that the quantum communication link fails.

[0068] Figure 1b The data flow diagram of the communication network fault self-recovery device according to the embodiment of the present disclosure is schematically shown. Figure 1b As shown, the communication system provided by the embodiment of the present disclosure includes: a main database, a backup database and a quantum communication network, wherein the quantum communication network includes a quantum communication device, a key device, a first routing device and a second routing device, and a GRE (Generic Routing Encapsulation, GRE) general routing encapsulation tunnel is pre-built between the first routing device and the second routing device. When any node on the quantum communication link fails, the communication quality of the GRE tunnel will be affected. Therefore, unified monitoring of multiple fault points is achieved by monitoring the link status of the GRE tunnel. When the quantum communication link failure is determined, the data transmission path is automatically switched to ensure normal data transmission.

[0069] Figure 2a The communication network fault self-recovery device according to the embodiment of the present disclosure is schematically shown. Figure 2aAs shown, the communication network fault self-recovery device provided by the embodiment of the present disclosure includes: A1 quantum communication link monitoring module, A2 link state judgment module, A3 transmission path switching module, A4 fault recovery judgment module, A5 data diversion module, and A6 alarm module. The A1 quantum communication link monitoring module is used to detect the state of the quantum communication link through a script. When the detection result is normal, this information is passed to the link state to the A4 fault recovery judgment module. When the detection result is abnormal, this information is passed to the A2 link state judgment module. The A2 link state judgment module receives information from the A1 quantum communication link monitoring module and the A4 fault recovery judgment module to judge and adjust the link state. The A3 transmission path switching module is used to switch the data transmission path to the traditional communication link in the event of a quantum communication link failure. The link state information input by the A2 link state judgment module is received, and the route pointing to the traditional link is effective by deleting the policy routing configured on the router port, thereby realizing the switching of the communication link. The A4 fault recovery judgment module is used to judge the recovery state of the quantum communication link, and after the quantum communication link is restored to stability, the data transmission is switched to the quantum encryption link. Receive the link status information input by the A1 quantum communication link monitoring module and the link status information input by the A2 link status judgment module. The A5 data diversion module receives the call from the A4 fault recovery judgment module, diverts the data transmission to the quantum communication link, and increases the policy routing configuration on the router port so that the route pointing to the quantum communication link takes effect, and data is transmitted through the quantum communication link. At the same time, the normal information of the quantum communication link is transmitted to the A5 alarm module. After receiving the information transmitted by the A2 transmission path switching module and the A5 data diversion module, the A6 alarm module sends an alarm information about the status of the quantum communication link.

[0072] The user can use the terminal devices 201, 202, 203 to interact with the server 205 through the network 204 to receive or send messages, etc. Various communication client applications can be installed on the terminal devices 201, 202, 203, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, social platform software, etc. (only as examples).

[0073] The terminal devices 201 , 202 , and 203 may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, and desktop computers.

[0074] Server 205 can be a communication network failure self-recovery server. The server can execute the communication network failure self-recovery method provided in the embodiment of the present disclosure, set a monitoring thread to run a script to monitor the communication quality of the GRE tunnel in real time, and then determine the state of the quantum communication link. After determining that the quantum communication link fails, the data transmission path is switched to minimize the impact on the business.

[0075] It should be noted that the communication network fault self-recovery method provided in the embodiment of the present disclosure can generally be executed by the server 205. Accordingly, the communication network fault self-recovery device provided in the embodiment of the present disclosure can generally be set in the server 205. The communication network fault self-recovery method provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the server 205 and can communicate with the terminal devices 201, 202, 203 and / or the server 205. Accordingly, the communication network fault self-recovery device provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the server 205 and can communicate with the terminal devices 201, 202, 203 and / or the server 205.

[0076] It should be understood that Figure 2b The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0077] It should be noted that the communication network fault self-recovery method and device determined in the embodiments of the present disclosure can be used in the field of quantum communication technology, the field of financial technology, and any field other than the financial field. The application field of the communication network fault self-recovery method and device determined in the embodiments of the present disclosure is not limited.

[0078] The following will be based on Figure 2a Describe the system architecture and Figure 2b The application scenario described by Figure 3 to Figure 5 The communication network failure self-recovery method of the embodiment of the present disclosure is described in detail.

[0079] Figure 3 The flowchart of a communication network fault self-recovery method provided according to an embodiment of the present disclosure is schematically shown. Figure 3 As shown, the communication network fault self-recovery method of this embodiment includes operations S210 to S230, and the method can be executed by a server or other computing devices.

[0080] In operation S210, the link status of the general routing encapsulation tunnel is monitored in real time.

[0081] According to an embodiment of the present disclosure, the method provided by the present disclosure is applied to a quantum communication network, which includes a quantum communication device, a key device, a first routing device and a second routing device, and a general routing encapsulation tunnel is pre-constructed between the first routing device and the second routing device.

[0082] According to an embodiment of the present disclosure, the quantum communication device includes a first quantum communication device and a second quantum communication device, the key device includes a first key device and a second key device, the quantum communication device is used to transmit a quantum key, the key device is used to quantum encrypt data to generate a quantum encrypted data stream, and the first routing device and the second routing device are used to transmit the quantum encrypted data stream.

[0083] In one example, a routing encapsulation tunnel is pre-built between the first routing device and the second routing device, and the link status of the general routing encapsulation tunnel is monitored by setting a script, which can be real-time monitoring or obtaining the link status of the general routing encapsulation tunnel at a preset frequency.

[0084] In operation S220, the quantum communication link state is determined according to the link state of the general routing encapsulation tunnel.

[0085] In operation S230, after determining that the quantum communication link fails, the data transmission path is switched.

[0086] In one example, after the link state of the GRE tunnel is determined according to operation S210, the current state of the quantum communication link is determined according to the link state of the GRE tunnel. When it is determined that the link state of the GRE tunnel is abnormal, it indicates that the current quantum communication link is faulty. After determining that the quantum communication link is faulty, the data transmission path is switched, and the quantum communication link is switched to a traditional data transmission link.

[0087] A communication network fault self-recovery method is provided by an embodiment of the present disclosure. The quantum communication network includes a quantum communication device, a key device, a first routing device and a second routing device. A general routing encapsulation tunnel is pre-constructed between the first routing device and the second routing device. The quantum communication link state is determined by real-time monitoring of the link state of the general routing encapsulation tunnel. After determining that the quantum communication link fails, the data transmission path is automatically switched to reduce the impact of the quantum communication link failure on the service, thereby improving the high availability of the service and user experience.

[0088] Figure 4 A flowchart of a communication network fault self-recovery method provided according to another embodiment of the present disclosure is schematically shown. Figure 5 A flowchart of a communication network fault self-recovery method provided according to another embodiment of the present disclosure is schematically shown.

[0089] like Figure 4 As shown, operations S310 to S360 are included.

[0090] In operation S310, the network transmission quality of the general routing encapsulation tunnel is detected in real time.

[0091] In operation S320, a link state of the general routing encapsulation tunnel is determined according to the network transmission quality.

[0092] In operation S330, the quantum communication link state is determined according to the link state of the general routing encapsulation tunnel.

[0093] According to an embodiment of the present disclosure, if it is determined that the link state of the general routing encapsulation tunnel is abnormal, a quantum communication link failure is determined; and the quantum communication link state flag is changed to failure.

[0094] According to an embodiment of the present disclosure, if it is determined that the link state of the general routing encapsulation tunnel is normal and the quantum communication link state flag is faulty, the quantum communication link state flag is changed to normal.

[0095] In one example, the link status of the GRE tunnel is determined by real-time monitoring of the network transmission quality of the GRE tunnel. If the link status is normal, regardless of whether the current quantum communication link status is normal or faulty, it indicates that the quantum communication link status is normal, and the current quantum communication link status is updated to normal. If the link status is abnormal, regardless of the current quantum communication link status, it indicates that the quantum communication link status is abnormal, and the current quantum communication link status is updated to faulty.

[0096] In operation S340, the policy routing configured on the router port is deleted.

[0097] In operation S350, the quantum communication link is switched to a target communication link, where the target communication link is a traditional communication link.

[0098] In operation S360, warning information of the quantum communication link status is sent.

[0099] like Figure 5 As shown, after operation S350, the following steps are also included: operation S410 to operation S440.

[0100] In operation S410, after determining that the link state of the general routing encapsulation tunnel has returned to normal for a preset time, the quantum communication link state flag is changed to normal.

[0101] In operation S420, adding a policy routing configuration on the router port; and

[0102] In operation S430, the target communication link is switched to the quantum communication link.

[0103] In operation S440, warning information of the quantum communication link status is sent.

[0104] In one example, after determining that the quantum communication link is faulty, the transmission path switching module switches the data transmission path to the traditional communication link. Specifically, by deleting the policy routing configured on the router port, the routing pointing to the traditional link takes effect, thereby realizing the switching of the communication link. After completing the automatic switching of the communication link, an alarm message of the quantum communication link status is sent, for example, an alarm message of "quantum communication link failure, transmission path has been switched" may be sent.

[0105] In one example, after the link status of the GRE tunnel is restored, in order to ensure the quality of data transmission and avoid link switching back and forth, it is necessary to determine that the link status of the GRE tunnel has been restored for a certain preset time before the traditional communication link can be switched to the quantum communication link. Specifically, the A4 fault recovery judgment module judges the recovery status of the quantum communication link, and after the quantum communication link is restored to stability, the data transmission is switched to the quantum encryption link. The preset time can be achieved by a counter. The A4 fault recovery judgment module receives the GRE link status information input by the A1 quantum communication link monitoring module and the quantum communication link status information input by the A2 link status judgment module. If the result of receiving the GRE link status information is abnormal, the quantum communication link status information is normal, and the quantum link status is set to fault. If the GRE link status information result status is faulty, the counter value is set to zero. If the result of receiving the GRE link status information is normal and the quantum communication link status is normal, the counter value is increased by 1. If the quantum communication link status is faulty, the quantum communication link status is set to normal, the counter value is increased by 1, and the link status information is passed to the A2 link status judgment module. When the counter value reaches 20, the A5 data diversion module is called to switch the target communication link to the quantum communication link, and the counter is cleared at the same time.
