[0061] The embodiments of the present disclosure will now 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 disclosure. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the present disclosure for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts of the present disclosure.

[0062] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

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

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

[0065] First, combine Figure 1a The technical background of this disclosure will be further described. Figure 1a The diagram illustrates the data flow of a quantum communication line in related technologies. In some business scenarios within the financial industry, quantum communication lines are used for data transmission to achieve real-time data synchronization between primary and backup databases within the same city, significantly improving security. For example... Figure 1a As shown, a dedicated quantum communication encryption device is introduced to encrypt data transmitted over traditional lines. A dedicated quantum communication key generation device generates the key, which is then transmitted via a separate fiber optic link. Routers are deployed between the central data center network and other data centers in the same city, routing the electronic archive data stream to these routers via policy-based routing. The quantum communication device transmits the negotiated key to the VPN encryption gateway, which performs encryption / decryption. The data stream is encrypted after passing through the VPN gateway and then transmitted to the peer node via the metropolitan area network transmission equipment. Upon passing through the peer VPN gateway, the data stream is decrypted and sent to the peer's internal network.

[0066] To ensure high availability of data transmission, it is necessary to maintain traditional lines even in the event of failures in quantum communication equipment. Since quantum encryption and key devices are dedicated devices, they are maintained by a dedicated quantum equipment maintenance unit according to operational responsibilities, and users cannot log in or monitor them. When a quantum device fails, the maintenance unit must manually notify operations personnel, who then follow the emergency manual for emergency procedures, resulting in a lengthy processing time. Traditional monitoring methods can only monitor the status of internal equipment and lines, failing to ensure the entire link remains operational. Multiple potential failure points need to be monitored on the quantum communication link; a failure at any point renders the quantum communication line unusable, necessitating unified monitoring of all points. Manually switching transmission paths after a failure is detected is time-consuming and significantly impacts business operations.

[0067] Based on the above-mentioned technical problems, embodiments of this disclosure provide a communication network fault self-recovery method applied to a quantum communication network. The quantum communication network includes a quantum communication device, a key device, a first routing device, and a second routing device. A universal 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 universal routing encapsulation tunnel; determining the quantum communication link status based on the link status of the universal routing encapsulation tunnel; and switching the data transmission path after determining that the quantum communication link is faulty.

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

[0069] Figure 2a A communication network fault self-recovery device according to an embodiment of this disclosure is illustrated schematically. For example... Figure 2aAs shown in the embodiments of this disclosure, the communication network fault self-recovery device includes: an A1 quantum communication link monitoring module, an A2 link status judgment module, an A3 transmission path switching module, an A4 fault recovery judgment module, an A5 data diversion module, and an A6 alarm module. The A1 quantum communication link monitoring module is used to detect the status of the quantum communication link via a script. When the detection result is normal, this information is passed to the A4 fault recovery judgment module; when the detection result is abnormal, this information is passed to the A2 link status judgment module. The A2 link status judgment module receives information from the A1 quantum communication link monitoring module and the A4 fault recovery judgment module, and judges and adjusts the link status. The A3 transmission path switching module is used to switch the data transmission path to a traditional communication link in the event of a quantum communication link failure. It receives the link status information input from the A2 link status judgment module, deletes the policy route configured on the router port, and thus makes the route pointing to the traditional link effective, achieving the switching of the communication link. The A4 fault recovery judgment module is used to judge the recovery status of the quantum communication link. After the quantum communication link has stabilized, the data transmission is switched to the quantum encrypted link. The A1 quantum communication link monitoring module and the A2 link status judgment module receive link status information from each other. The A5 data diversion module receives a call from the A4 fault recovery judgment module and diverts data transmission to the quantum communication link. By adding policy routing configurations on the router port, the route pointing to the quantum communication link becomes effective, and data transmission occurs through the quantum communication link. Simultaneously, it transmits normal quantum communication link information to the A5 alarm module. The A6 alarm module, upon receiving information from the A2 transmission path switching module and the A5 data diversion module, sends alarm information regarding the quantum communication link status.

[0070] Figure 2b The illustration schematically depicts an application scenario of a communication network fault self-recovery method, apparatus, device, storage medium, and program product according to embodiments of the present disclosure.

[0071] like Figure 2b As shown, application scenario 200 according to this embodiment may include a communication network fault self-recovery scenario. Network 204 is used as a medium to provide a communication link between terminal devices 201, 202, 203 and server 205. Network 204 may include various connection types, such as wired, wireless communication links, or fiber optic cables, etc.

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

[0073] Terminal devices 201, 202, and 203 can be various electronic devices with displays that support web browsing, including but not limited to smartphones, tablets, laptops, and desktop computers.

[0074] Server 205 can be a communication network fault self-recovery server. This server can execute the communication network fault self-recovery method provided in the embodiments of this disclosure, set up a monitoring thread to run a script to monitor the communication quality of the GRE tunnel in real time, thereby determining the quantum communication link status. After determining that the quantum communication link is faulty, it switches the data transmission path to minimize the impact on services.

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

[0076] It should be understood that Figure 2b The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.

[0077] It should be noted that the communication network fault self-recovery method and apparatus determined in the embodiments of this 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 apparatus determined in the embodiments of this disclosure is not limited.

[0078] The following will be based on Figure 2a The system architecture described and Figure 2b The described application scenarios, through Figures 3-5 The communication network fault self-recovery method according to the embodiments of this disclosure will be described in detail.

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

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

[0081] According to embodiments of this disclosure, the method provided in this 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, wherein a universal routing encapsulation tunnel is pre-built between the first routing device and the second routing device.

[0082] According to embodiments of this 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. The link status of the general routing encapsulation tunnel is monitored by setting a script. This monitoring can be done in real time or by acquiring the link status of the general routing encapsulation tunnel at a preset frequency.

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

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

[0086] In one example, after determining the link state of the GRE tunnel according to operation S210, the current state of the quantum communication link is determined based on 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 has failed. After determining that the quantum communication link has failed, the data transmission path is switched, and the quantum communication link is switched to a traditional data transmission link.

[0087] The present disclosure provides a communication network fault self-recovery method. The quantum communication network includes a quantum communication device, a key device, a first routing device, and a second routing device. A universal routing encapsulation tunnel is pre-built between the first routing device and the second routing device. The quantum communication link status is determined by real-time monitoring of the link status of the universal routing encapsulation tunnel. After a quantum communication link fault is determined, the data transmission path is automatically switched to reduce the impact of the quantum communication link fault on services and improve the high availability of services and user experience.

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

[0089] like Figure 4 As shown, this includes operations S310 to S360.

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

[0091] In operation S320, the link status of the general routing encapsulation tunnel is determined based on the network transmission quality.

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

[0093] According to embodiments of this disclosure, if it is determined that the link state of the general routing encapsulation tunnel is abnormal, then a quantum communication link failure is determined; and the quantum communication link state identifier is changed to failure.

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

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

[0096] When operating S340, delete the policy route configured on the router port.

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

[0098] When operating the S360, send alarm information about the quantum communication link status.

[0099] like Figure 5 As shown, after operation S350, operations S410 to S440 are also included.

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

[0101] When operating the S420, add policy-based routing configuration to the router port; and

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

[0103] When operating the S440, an alarm message about the quantum communication link status is sent.

[0104] In one example, after a quantum communication link failure is detected, the transmission path switching module switches the data transmission path to a traditional communication link. Specifically, this is done by deleting the policy route configured on the router port, thus making the route pointing to the traditional link effective and achieving the communication link switch. After the automatic switching of the communication link is completed, an alarm message regarding the quantum communication link status is sent, such as an alarm message stating "Quantum communication link failure, transmission path switched".

[0105] In one example, after the GRE tunnel link status is restored, to ensure data transmission quality and avoid link switching back and forth, a certain preset time must be allowed for the GRE tunnel link status to recover before switching from the traditional communication link to the quantum communication link. Specifically, the A4 fault recovery judgment module determines the recovery status of the quantum communication link. After the quantum communication link stabilizes, data transmission is switched to the quantum encrypted link. The preset time can be implemented using a counter. The A4 fault recovery judgment module receives GRE link status information from the A1 quantum communication link monitoring module and quantum communication link status information from the A2 link status judgment module. If the received GRE link status information is abnormal, but the quantum communication link status information is normal, the quantum link status is set to fault. If the GRE link status information indicates a fault, the counter value is set to zero. If the received GRE link status information is normal and the quantum communication link status is normal, the counter value is incremented by 1. If the quantum communication link status is faulty, the quantum communication link status is set to normal, the counter value is incremented by 1, and the link status information is transmitted 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 to zero.
