Description

Method for dual-homing device management system and dual-homing data configuration rollback

The present invention relates to the field of telecommunications technologies, and in particular, to a dual-homed device management system and a dual-homed data configuration rollback method. Background technique

In order to be able to adapt to the future communication and business development needs, it is imperative for the communication network to evolve to the NGN (Next Generation Network) with softswitch as the core. Previously, in the NGN of telecommunications, dual-homing management of softswitches was required. Dual-homing is a disaster-tolerant mechanism that prevents soft-switching equipment from crashing or providing emergency communications in the event of a sudden disaster. It is guaranteed by mutual backup between two sets of softswitch systems in different geographical locations. When one of the softswitch devices fails, the other softswitch device can take over all of its services, thus ensuring the communication security of the network in an emergency. When the data and services on the two devices are backed up, the two devices are two devices with dual-homing relationship. The two devices that have dual-homing relationships require completely consistent or basically consistent data as dual-homed data. .

When the data is configured on the two devices with the dual-homing relationship, the NMS needs to send the configuration commands to the two softswitches. However, in actual use, there may be cases where only one softswitch configuration is successful and the other softswitch configuration fails. To ensure that the data is consistent between the two softswitches, you need to use the data configuration rollback method to undo the data configuration command on the successfully configured softswitch to restore the data to the state before the data configuration is successful.

There are now two ways to configure rollback for dual-homed data. One is that the network management system uses the query interface of the device to query and save the data information to be updated before performing data configuration on the softswitch. If the data configuration fails, the configuration command is configured according to the information that is queried before the configuration. The command is sent to the softswitch that is successfully configured. The softswitch receives the command and runs the command to implement rollback of the dual-homed data configuration.

Another method is that the network management saves the data in the network management before configuring the data on the softswitch. The data is backed up. If the data configuration fails, the current configuration data is replaced with the backed up data, thereby implementing rollback of the dual-homed data configuration.

However, the inventor noticed in the process of the invention that when the method for configuring the rollback of the first type of dual-homing data is used, the insufficiency is: Since the network management needs to perform a query on the device data before the configuration, the number of interactions with the device is determined by Once changed to twice, the dual-homing configuration command processing efficiency is reduced to half.

The disadvantages of using the second dual-homed data configuration rollback method are as follows: Because different data structures are different, the network management system needs to prepare different data backup structures for different data, resulting in an increase in system complexity. In the case that the dual-homed data is completely configured successfully, the backup data needs to be cleared, so that the number of data operations is increased, which affects system efficiency. Summary of the invention

The problem to be solved by the embodiments of the present invention is to provide a dual-homing device management system and a dual-homed data configuration rollback method to overcome the shortcomings of the system in the prior art when the configuration of the dual-homed data is rolled back.

An embodiment of the present invention provides a dual-homing data configuration rollback method, including the following steps: acquiring configuration data and setting a data state of the configured data;

Configuring two devices having a dual-homing relationship according to the configuration data;

The restoration of the data configuration is performed according to the configuration data and the data state of the configuration data. The embodiment of the present invention further provides a dual-homed device management system, which includes a user unit, a network management unit, and a dual-homed device unit, wherein the network management unit is respectively connected to the user unit and the dual-homed device unit, and is configured to acquire configuration data and set the The data state of the data is configured, and the data configuration of the successfully configured softswitch is restored according to the configuration data and the data state of the configuration data.

Advantageous effects of the embodiments of the present invention:

The embodiment of the present invention does not require the network management system to query the device data before the configuration, and does not need to back up and clear the data stored in the network management system. Therefore, when the configuration of the dual-homed data is rolled back, the efficiency of the system is improved. DRAWINGS

FIG. 2 is a schematic flowchart of the dual-homing data configuration rollback in the embodiment of the present invention. detailed description

The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings and embodiments. FIG. 1 is a schematic diagram of a dual-homing device management system. As shown in the figure, the dual-homing device management system includes a subscriber unit 11, a network management unit 12, and The dual-homed equipment unit 13 , wherein the dual-homed equipment unit 13 further comprises a soft switch 14 and a soft switch 15 . The network management unit 12 communicates with the subscriber unit 11 and the dual-homed equipment unit 13 respectively, and manages the dual-homed equipment unit 13.

Figure 2 is a schematic diagram of the flow of the dual-homed data configuration rollback. As shown in the figure, the dual-homing device management system is implemented as an example.

First, the network management unit 12 acquires the configuration data and sets the data state of the configuration data. When the data state is 0, it indicates that the data is to be updated. When the data state is 1, it indicates that the data has been updated. Then, the network management unit 12 pairs the data according to the configuration data. The home device unit 13 performs configuration. When only one configuration of the softswitch 14 and the softswitch 15 is successful, the configuration of the softswitch 14 is successful, the configuration of the softswitch 15 is failed, and the dual-homing data needs to be configured for rollback. 12: Perform data configuration recovery on the configured softswitch according to the configuration data and the data state of the configuration data. Referring to Figure 2, the implementation may include the following steps:

Step 101: Synchronize and save the configuration data of the two devices with the dual-homing relationship to the network management unit. That is, the soft switch 14 and the soft switch 15 of the dual-homed equipment unit 13 respectively transmit the configuration data to the network management unit 12 for synchronization.

Step 102, set two that have a dual-homing relationship. The data status of the corresponding configuration data of the device. That is, the data state of the configuration data corresponding to the soft switch 14 and the soft switch 15 is set to 1, respectively.

Step 103: Configure two devices that have a dual-homing relationship and update the data state of the corresponding configuration data. The user unit 11 sends a configuration command to the network management unit 12, and the network management unit 12 delivers the configuration. The configuration command is sent to the softswitch 14 and the softswitch 15, and the softswitch 14 and the softswitch 15 respectively execute the configuration command to configure the dual-homed device unit 13. If the configuration of the softswitch device is successful, the data state of the corresponding configuration data of the device is set to 0. If the configuration of the softswitch device fails, the data state of the corresponding configuration data of the device is not changed. That is, the data state of the configuration data corresponding to the soft switch 14 is set to zero.

Step 104: Determine whether all the devices with the dual-homing relationship are successfully configured. If yes, go to step 109; otherwise, go to step 105. That is, it is judged whether the soft switch 14 and the soft switch 15 are all configured successfully. Since the configuration of the soft switch 14 is successful, the configuration of the soft switch 15 fails, so the process proceeds to step 105.

Step 105: Determine whether all the devices with the dual-homing relationship fail to be configured, and if yes, end; otherwise, go to step 106. That is, it is judged whether all the softswitch 14 and the softswitch 15 fail to be configured. Because the configuration of the softswitch 14 is successful, the configuration of the softswitch 15 fails, so the process goes to step 106. .

Step 106: Generate a reverse configuration command according to the configuration data of the successfully configured device among the two devices that have the dual-homing relationship. That is, the network management unit 12 generates a reverse configuration command based on the configuration data of the soft switch 14.

Step 107: The device configured successfully in the two devices with dual-homing relationship performs a reverse configuration command. That is, the network management unit 12 sends the generated reverse configuration command to the soft switch 14, and the soft switch 14 executes the reverse configuration command to restore the data of the soft switch 14 to the state before the configuration succeeds.

Step 108: Change the data state of the corresponding configuration data of the successful device in the two devices in which the dual-homing relationship exists, and end. That is, the network management unit 12 sets the data state of the configuration data corresponding to the soft switch 14 to 1 and ends.

Step 109: Copy the configuration data of the two devices that have the dual-homing relationship to the network management unit.

Step 110: Change the data shape of the corresponding configuration data of the two devices that have the dual-homing relationship. If the two devices that have the dual-homing relationship are configured, the softswitch 14 and the softswitch 15 are configured successfully, and If the data state of the softswitch 14 and the softswitch 15 corresponding to the configuration data is set to 0, then step 109 is performed to copy the configuration data of the softswitch 14 and the softswitch 15 to the network management unit 12; the copying process may be performed immediately or in a section. The automatic copying is performed after the time, or when the network management unit 12 needs to use the data. After the copying process is completed, step 111 is performed, and the data state of the configuration data corresponding to the softswitch 14 and the softswitch 15 is set to 1. The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It should be considered as the scope of protection of the present invention.
