[0055] The embodiment of the present application provides a method and device for processing network services. The method provided by the embodiment of the present invention can be applied to any required electronic device, for example, it can be a server, a terminal and other electronic devices, which are not specifically limited here, and for the convenience of description, they are referred to as electronic devices in the following.

[0056] According to one aspect of the embodiments of the present application, a method embodiment of a method for processing a network service is provided. Figure 1 A flowchart of a method for processing network services provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes:

[0057] Step S11, obtaining first configuration information corresponding to the network service currently to be issued.

[0058] The method for processing network services provided in the embodiment of the present application is applied to a software defined network (SDN) controller. When a user has a need to configure a network service, the user sends first configuration information of the network service to the SDN controller through a client, where the first configuration information may include: the network environment required for the network service and resource information required for the service operation, etc.

[0059] Step S12: Send the first configuration information to the active device in the target group, and store the first configuration information in the persistent database of the standby device in the target group.

[0060] In the embodiment of the present application, before sending the target configuration information to the primary device in the target group, the method further includes the following steps A1-A2:

[0061] Step A1, obtaining performance parameters corresponding to the SDN controller associated candidate group.

[0062] Step A2: determine the candidate group whose performance parameters meet the requirements of the SDN controller as the target group.

[0063] In an embodiment of the present application, an SDN controller-associated candidate group is obtained from a resource pool, and the performance parameters corresponding to each candidate group are determined. Since the SDN controller is deployed in a cloud resource cluster, and an association relationship is established between the cloud resource cluster and the resource pool, the SDN controller can select a candidate group whose performance parameters meet the controller requirements from the resource pool as a target group. Among them, the performance parameters include: CPU parameters, memory parameters, hard disk parameters, interface parameters, etc. The candidate group whose performance parameters meet the requirements of the SDN controller can be the candidate group with the highest performance parameters.

[0064] In the embodiment of the present application, after determining the target group, the SDN controller will send the first configuration information to the active device in the target group, and also store the first configuration information in the persistent database of the standby device in the target group. By storing the configuration information in the persistent database of the standby device, it can be ensured that in the event of a failure of the active device in the subsequent target group, the standby device of the target group can obtain the relevant configuration information from the persistent database, thereby ensuring that network services can be normally interoperable.

[0065] In the embodiment of the present application, after receiving the first configuration information, the active device in the target group will perform corresponding business processing according to the first configuration information. At the same time, the backup device in the target group will also monitor the status information of the active device. If the active device fails or hangs up at this time, the backup device in the target group does not receive the heartbeat message of the active device within the preset time, and the target backup device for receiving the configuration information instead of the active device will be selected.

[0066] Step S13: receiving status information corresponding to the master device fed back by the target cluster, and suspending the operation of sending configuration information to the master device when it is determined that the master device is in an abnormal state according to the status information.

[0067] In the embodiment of the present application, the SDN controller receives the status information sent by the target group and determines whether the status information comes from the backup device in the target group or the main device in the target group. If the status information comes from the backup device in the target group, it is determined that the main device is in an abnormal state, and the operation of sending configuration information to the main device is suspended.

[0068] In the embodiment of the present application, after suspending the operation of sending configuration information to the primary device, the method further includes the following steps B1-B3:

[0069] Step B1, obtaining second configuration information corresponding to the network service to be issued.

[0070] Step B2: query whether there is third configuration information associated with the active device in the second configuration information.

[0071] Step B3: When the third configuration information associated with the primary device exists in the second configuration information, the third configuration information is stored in the persistent database.

[0072] In the embodiment of the present application, after the SDN controller suspends the operation of sending configuration information to the primary device, if the SDN controller continues to receive the second configuration information and inquires whether the second configuration information carries the third configuration information sent to the primary device, at this time, since the SDN controller suspends sending the third configuration information to the primary device, the third configuration information will be stored in the persistent database first, and the SDN controller will send the third configuration information to the primary device after the primary device is online. In addition, since the primary device in the target group is abnormal, the third configuration information needs to be sent to the target backup device, and the target backup device is used to currently replace the primary device to receive the configuration information.

[0073] Step S14, obtaining a target standby device in the target group that currently replaces the active device to receive configuration information, and executing a configuration information distribution operation on the target standby device.

[0074] The method provided in the embodiment of the present application can realize permanent storage of network services, and at the same time, combined with the active-standby switching mechanism, ensure that network services are not interrupted, and can respond to equipment failure problems in a timely manner. It supports users to configure services at any time and improves user experience. For service providers, multi-level protection increases system stability.

[0075] In the embodiment of the present application, after executing the operation of issuing configuration information to the target standby device, the method further includes the following steps C1-C2:

[0076] Step C1, receiving online notification information from the primary device.

[0077] Step C2: acquiring third configuration information from the persistent database based on the online notification information, and sending the third configuration information to the active device.

[0078] In the embodiment of the present application, the SDN controller also receives the online notification information of the primary device, which is sent after the primary device goes online. At this time, the SDN controller obtains the third configuration information from the persistent database based on the online notification information and sends the third configuration information to the primary device.

[0079] Figure 2 A flowchart of a method for processing network services provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the method may include the following steps:

[0080] Step S21: The primary device and the backup device respectively receive first configuration information sent from the SDN controller, and determine the state information of the primary device, wherein the backup device stores the received first configuration information in a persistent database.

[0081] Step S22: When the status information is used to determine that the active device is in an abnormal state, the active device automatically clears the configuration information in the active device and determines a target standby device that receives the configuration information in place of the active device.

[0082] Step S23: obtaining a currently stored configuration information set from a persistent database through the target standby device, and restoring network services based on the configuration information set, wherein the configuration information set includes the first configuration information.

[0083] The method provided by the embodiment of the present application can realize the permanent storage of network services, and at the same time, combined with the active-standby switching mechanism, ensure the uninterrupted network services, and promptly respond to equipment failure problems. It supports users to configure services at any time and improves user experience. For service providers, multi-level protection increases system stability.

[0084] In the embodiment of the present application, determining the status information of the primary device includes the following steps D1-D2:

[0085] Step D1, the backup device monitors the heartbeat message sent by the active device within a preset time to obtain the message sending result of the active device within the preset time.

[0086] Step D2, determining the status information of the main device according to the message sending result.

[0087] In the embodiment of the present application, after receiving the first configuration information, the standby device monitors the heartbeat message sent by the active device, and if the standby device receives the heartbeat message sent by the active device within a preset time, it is determined that the status information of the active device is in a normal state. If the standby device does not receive the heartbeat message sent by the active device within the preset time, it is determined that the status information of the active device is in an abnormal state.

[0088] In an embodiment of the present application, when the status information is used to determine that the primary device is in an abnormal state, the method also includes: sending the status information corresponding to the primary device to the SDN controller through the backup device, so that the SDN controller suspends the operation of sending configuration information to the primary device based on the status information.

[0089] In the embodiment of the present application, after sending the first configuration information to the target standby device, the method further includes the following steps E1-E3:

[0090] Step E1, monitoring the status information of the main device.

[0091] Step E2: When it is determined according to the status information that the active device is in a normal state, online notification information is sent to the SDN controller.

[0092] Step E3: receiving third configuration information sent by the SDN controller, wherein the third configuration information is configuration information received by the SDN controller after suspending the operation of sending configuration information to the active device.

[0093] In an embodiment of the present application, when a force majeure failure occurs in the target group in the resource pool, for example, both the main equipment and the backup equipment in the target group fail or are offline, a disaster recovery backup network device is required, and the same service can be configured for service migration. The SDN controller then selects the best group other than the target group from the remaining candidate groups in the current resource pool as the new target group. At this time, the SDN controller obtains the configuration information of the main and backup equipment in the original target group, and then migrates the configuration information to the main and backup equipment in the new target group, so that the new target group processes related network services based on the configuration information. This provides a disaster recovery backup network device when a force majeure failure occurs in the resource pool.
