Description

Technical Field

[0001] The present invention relates to the technical field of fast replacement of faulty OLT, and more specifically, to a method and system for fast replacement of faulty OLT equipment and a computer storage medium. Background Art

[0002] During engineering maintenance, when an OLT fails and the device cannot be started, maintenance personnel go to the site to replace the OLT. Since the faulty OLT cannot be started normally, the configuration cannot be copied from the faulty OLT to the replacement device. Therefore, the operation and maintenance personnel need to manually configure the replacement OLT to the same configuration as the faulty OLT or import the configuration file when it was deployed to restore network use. However, manually reconfiguring the device and restoring the network requires additional manpower and material resources, especially in large networks, which increases operating costs. In addition, it not only requires high professional skills for maintenance personnel, but also has low efficiency, which is easy to cause various hidden risks such as missing configurations. There is also a configuration consistency problem by importing the deployed configuration file. In the existing network, OLT devices will add or modify configurations as business needs. If the operation and maintenance personnel forget to back up again, the configuration file is not the latest, and configuration inconsistency is likely to occur. Inconsistent configuration will lead to management confusion and increase maintenance difficulty. At the same time, it may cause the traffic management policy to fail, causing network congestion and performance degradation. The priority setting of key services may be lost, resulting in reduced service quality and affecting user experience. It may cause the device to fail to work properly, which in turn causes network interruption and service unavailability. Network interruption will cause business interruption and economic losses. Service unavailability affects customer satisfaction and may result in customer churn. Summary of the invention

[0060] In a specific embodiment, in order to achieve fast and efficient replacement of faulty OLT devices and restore network use. A new method is added, that is, when the OLT device is installed, it is connected to the network management system through the MQTT protocol, and the OLT device encapsulates the configuration into the JSON data exchange format and actively sends it to the network management through MQTT. When the OLT fails, the maintenance personnel replaces it with a normal OLT, logs in to the APP, enters the faulty OLT MAC and the replacement OLT MAC on the fault replacement page, and submits the information to the network management system. The network management system automatically sends the configuration of the faulty OLT to the replacement OLT, so that the network can be quickly restored to use.

[0061] In addition, by subscribing to the MQTT topic, when the OLT device configuration changes, the OLT will actively report it to the network management, and the network management will send and obtain the OLT configuration, so as to achieve real-time update and save the OLT configuration, ensuring the consistency of the OLT configuration.

[0062] The technical solution of the present invention consists of five parts, namely: the network management system is deployed to the cloud server; the OLT device uploads the configuration to the network management system; the network management updates the OLT configuration in real time; the network management system obtains the fault and replaces the OLT MAC; the network management system sends the configuration to the replacement OLT to realize the rapid recovery of the network.

[0063] The following is a detailed description:

[0064] 1. Deploy the network management system to the cloud server:

[0065] The cloud service builds an MQTT server (or MQTT broker) for forwarding MQTT messages. The publish / subscribe message mode used by MQTT designs the topic of device configuration changes as: PP_(config_file_change).

[0066] 2. Upload the OLT device configuration to the network management system:

[0067] After the network management system is deployed to the cloud server, when the OLT device is installed and deployed, log in to the OLT web interface to configure the network management system address. The OLT device is connected to the network management system through the MQTT protocol. The OLT device encapsulates the configuration into JSON data exchange format and actively sends it to the network management through MQTT. The network management receives the data, parses the device configuration through the JSON format data, and saves it on the network management system.

[0068] 3. The network management obtains the current configuration of OLT in real time

[0069] In the existing network, OLT devices will add or modify configurations as business needs demand. When the OLT device configuration is changed, in order to ensure that the OLT configuration saved by the network management system is the latest configuration, a message is sent to the network management system through the MQTT publishing topic PP_(config_file_change). When the network management system receives the subscribed topic, it actively sends a query message to the OLT. The OLT receives the query message and also reports the configuration in JSON format through MQTT. The network management receives the data, parses the device configuration through the JSON format data, and saves it on the network management system.

[0070] 4. The network management system obtains fault information and replaces OLT MAC

[0071] Install the network management APP on your mobile phone, enter the network management system server address on the APP, and the APP communicates with the network management system through the HTTP protocol. When the OLT fails, the maintenance personnel replace it with a normal OLT, and then install the replaced OLT in step 2 to connect to the network management system. At the same time, enter the faulty OLT MAC and the replacement OLT MAC on the fault replacement page of the APP. The APP submits the information to the network management system through the http protocol.

[0072] 5. The network management system sends configuration to the replacement OLT to achieve rapid network recovery

[0073] The network management system receives the fault and replacement OLT MAC sent by the APP, finds the corresponding configuration file through the faulty OLT MAC, encapsulates the configuration into JSON format, and sends the configuration to the replacement OLT through MQTT. The replacement OLT receives the MQTT message, parses the JSON data, and performs configuration.

[0074] Realize the application networking of fast recovery of faulty OLT network Figure 2 As shown, the method is as Figure 3 and Figure 4 As shown below:

[0075] The first step is to deploy the network management system to the cloud server: the cloud service builds an MQTT server (or MQTT broker) for forwarding MQTT messages; the publish / subscribe message mode used by MQTT designs the topic of device configuration changes as: PP_(config_file_change);

[0076] The second step is to upload the OLT device configuration to the network management system: After the network management system is deployed to the cloud server, when the OLT device is installed and deployed, log in to the OLT web interface to configure the network management system address. The OLT device is connected to the network management system through the MQTT protocol. The OLT device encapsulates the configuration into JSON data exchange format and actively sends it to the network management through MQTT. The network management receives the data, parses the device configuration through the JSON format data, and saves it on the network management system.

[0077] Step 3: The network management obtains the current configuration of the OLT in real time: In the existing network, the OLT device will add or modify the configuration as the business needs. When the OLT device configuration is changed, in order to ensure that the OLT configuration saved by the network management system is the latest configuration, a message is sent to the network management system through the MQTT publishing topic PP_(config_file_change). When the network management system receives the subscription topic, it actively sends a query message to the OLT. The OLT receives the query message and also reports the configuration in JSON format through MQTT. The network management receives the data, parses the device configuration through the JSON format data, and saves it on the network management system.

[0078] Step 4: The network management system obtains the fault and replacement OLT MAC: Install the network management APP on the mobile phone, enter the network management system server address on the APP, and the APP communicates with the network management system through the HTTP protocol. When the OLT fails, the maintenance personnel replace it with a normal OLT, and then install the replaced OLT in step 2 and connect it to the network management system. At the same time, enter the fault OLT MAC and the replacement OLT MAC on the fault replacement page of the APP. The APP submits the information to the network management system through the http protocol.

[0079] Step 5: The network management system sends the configuration to the replacement OLT to achieve rapid network recovery: The network management system receives the fault and replacement OLT MAC sent by the APP, finds the corresponding configuration file through the faulty OLT MAC, encapsulates the configuration into JSON format, and sends the configuration to the replacement OLT through MQTT. The replacement OLT receives the MQTT message, parses the JSON data, and performs configuration.
