Description

Method, device and device for business cutover

Technical field

The present application relates to, but is not limited to, the field of communications, and in particular, to a method, device and device for service cutover.

Background technique

Cutover is a key step in the network transformation, which will directly affect the services carried on the network. Business cutover, also called business migration, refers to physical or logical changes to the running network. Service cutover is an important technology and means in network maintenance, and it is the guarantee to maintain the network's continued good operation.

With the rapid development of communication technology and the innovation of communication equipment, the network management system is becoming more and more large, and the types and quantity of management equipment are increasing. The business needs are expanding and the management business is increasing. The switchover service can quickly check whether the service after the cutover is running normally. For example, if there are more than 10,000 services in a network management system, the number of services that need to be cut over the day may reach 100. Whether the optical power meets the requirements of the existing network, whether it is consistent with the cutover, and whether the optical power deviation is acceptable, so as to confirm whether each service can operate normally.

The current general practice is that the cutover personnel select the services and cut them one by one. Before the cutover, the current optical power of the existing service is recorded. After the cutover, the optical power of the service is viewed again, and the comparison is manually performed. If the power is consistent or the deviation is not large, the service is considered to be running normally after the cutover. If the service optical power is too small before and after the cutover, manually adjust or adjust the amplifier gain or adjust the Line Attenuation Compensator (LAC) attenuation. Although this method can be cut and cut correctly, it is too time-consuming and labor-intensive. It takes a few minutes for a service to be confirmed after the completion of the cutover, and it takes several hours for a hundred businesses. At the same time, the cutover of the existing network is carried out under the premise of ensuring that the normal service communication is not affected. Therefore, the cutover is generally selected in the middle of the night. After the frequent operation of the cutover personnel in the middle of the night, the probability of error is relatively large, and the service is normal. The operation has a big impact.

FIG. 2 is a structural block diagram of an apparatus for service cutover according to an embodiment of the present invention.

Preferred embodiment of the invention

Embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that there is no conflict In the case, the embodiments of the present application and the various aspects of the embodiments may be combined with each other.

As shown in FIG. 1 , an embodiment of the present invention provides a method for service cutover, including: Step 1: Receive, by the network management, a configuration of a service to be cut and cut in the cutover group. The NMS receives the configuration of the service to be cut in the cutover group. The cutover group can be configured in multiples according to the area. After the cutover group is cut, the service cut of another cutover group is performed. To ensure that the original service cutover time will not be exceeded due to service optical power adjustment. Step 2: Query the optical power of each service in the cutover group, and set the reference optical power and threshold of each service according to the query result. The current optical power or historical optical power of each service in the cutover group can be set to the value of the reference optical power. The deviation threshold (that is, the threshold) can be set according to requirements. In step 3, the service to be cut and cut in the cutover group is cut; in step 4, after the cutover is successful, the current optical power of each service in the cutover group that is queried again is compared with the reference optical power; 5, when the deviation of the optical power is within the threshold value, it is judged that the service after the cutover is normal; in step 6, when the deviation of the optical power is not within the threshold, it is determined that the service after the cutover is abnormal, and Send an error message. This can alert the technician to adjust the error-producing service to ensure that the optical power deviation of the adjusted service is within the threshold. The method effectively solves the problem that the service cutover mode in the related art is time-consuming and laborious and error-prone; and can compare the optical power deviation of the service before and after the cutover in batches, so as to quickly confirm whether the service after the cutover is running normally, and whether adjustment is needed.

Optionally, after determining that the service after the cutover is abnormal and sending an error prompt message, the method further includes: highlighting the service according to the error prompt information, and adjusting the service Then query the current optical power of the service again.

Optionally, before the step of configuring, by the network management, the service to be cut and cut in the cutover group, the method further includes: configuring the service to be cutover in the cutover group, and saving the information of the cutover group And naming the cutover group through the cutover area or the cutover order.

Optionally, the service to be cut and cut can be provided by the network management system, and can be filtered by the network management device according to the source and sink points. It should be noted that the network management system can be a software platform for managing business.

The method for service cutover in the embodiment of the present invention is described below in conjunction with an optional implementation manner.

Step 1: Receive the configuration of the service to be cut in the cutover group through the NMS, select the service to be cut, and save the cutover group in the cutover group module. The cutover group can be named according to the cutover area, and the services in the relevant area that need to be cutover are set in the cutover group named in the area. Like naming For Xiaoshan 20150715, it represents the cutover group where the business of the Xiaoshan area needs to be cut off on July 15, 2015. It can also be named according to the cutover order, for example, named 20150715_1, which represents the first business cutover group that needs to be cut and cut on July 15, 2015. Configure the cutover group to be idle during the daytime to save time for night service cutover.

Step 2: The optical power query module queries the optical power of each service in the cutover group, and sets the reference optical power and the deviation threshold of each service. The reference optical power and the deviation threshold are stored in the cutover group module. The service optical power can be uniformly queried for all services in the cutover group, which improves query efficiency. The reference optical power can be set to the current optical power or the historical optical power. The default reference optical power provided by the NMS can be the current optical power of the service.

The deviation threshold can be a range, and the network management can provide a default deviation threshold, such as [-M, N], ie, low threshold-M, high threshold N. That is, if the service optical power after the cutover is lower than the reference optical power N and higher than the reference optical power M, the deviation of the optical power is within the deviation threshold, thereby confirming that the service still operates normally after the cutover; On the other hand, if the service optical power after the cutover is lower than the reference optical power M and higher than the reference optical power N, the deviation of the optical power is outside the deviation threshold range, thereby confirming that the service needs to be adjusted after the cutover.

Set the reference optical power and the deviation threshold, which can be performed during the idle time during the day, saving the time for the business cutover at night. If the default deviation threshold provided by the network management system meets the requirements, the deviation threshold may not be set. The deviation thresholds of different cutover groups can be different. The setting of the deviation thresholds for different business areas can be diversified to meet different needs. Steps 1 and 2 are required to be completed before the cutover. The service can be completed before the cutover, saving time for late-night cutover work.

Step 3: After the two steps are completed, the cutover module performs cutover for the services in the cutover group.

Step 4: After the switchover module returns successfully, the optical power query module queries the current optical power of the service in the cutover group again. The optical power deviation can determine whether the deviation between the current optical power and the reference optical power after the cutover is within the deviation threshold. If the result of the determination is that the optical power deviation is within the deviation threshold, the optical power deviation determination module reports the determination result to the cutover group module, so that the cutover group module confirms that the service operation is normal after the cutover; if the judgment result is the optical power deviation Outside the deviation threshold, the optical power deviation determination module reports the determination result to the cutover group module, so that the cutover group module highlights the service. If the switchover module is highlighted in red, the switchover personnel can quickly locate that the service is not working properly after the cutover, and needs to be adjusted to adjust the service. Gain gain or adjust LAC attenuation. The adjusted optical power query module can continue to query the current optical power of the service, and the optical power deviation judgment module can continue to determine whether the current service optical power deviation falls within the deviation threshold. If the optical power deviation falls within the deviation threshold, it can be confirmed that the service can be normally operated after the cutover, and the adjustment ends. If the optical power deviation still falls outside the deviation threshold, the adjustment can be continued until the optical power deviation falls within the deviation threshold, and the service adjustment ends.

For example, if the service optical power is 3 before the cutover and the reference optical power is the current optical power, the reference optical power is 3, and the set deviation threshold is [-1, 1].

After the service is cut and the service is cut, the current optical power of the service is queried again. The current optical power is 3.5, and the optical power deviation is the current optical power 3.5-reference optical power 3=0.5, which falls within the deviation threshold, and the service can operate normally before and after the cutover. Or the current optical power is 2.5, and the optical power deviation is the current optical power 2.5-reference optical power 3=-0.5, which falls within the deviation threshold, and the service can operate normally before and after the cutover.

On the other hand, if the current optical power of the service after the cutover is 4.5, the optical power deviation is the current optical power 4.5-reference optical power 3=1.5, which falls outside the deviation threshold, and the service needs to be adjusted, otherwise the service cannot operate normally. After adjusting the amplifier gain or adjusting the LAC attenuation, the current optical power of the service can be queried again until the optical power deviation falls within the deviation threshold, and the service adjustment ends.

Or, if the current optical power of the service after the cutover is 1.9, the optical power deviation is 1.9 of the current optical power and the reference optical power is 3=-1.1, and the service needs to be adjusted if the current optical power is outside the deviation threshold. Otherwise, the service cannot be operated normally. After adjusting the amplifier gain or adjusting the LAC attenuation, the current optical power of the service can be queried again until the optical power deviation falls within the deviation threshold, and the service adjustment ends.

Comparison; when the deviation of optical power is within the threshold value, the judgment cut The connected service runs normally. When the deviation of the optical power is not within the threshold, it is judged that the service after the cutover is abnormal, and an error message is sent.

Optionally, the cutover group module 100 is configured to: manage the cutover service, and configure the service that needs to be cutover to the corresponding cutover group in advance, and wait for the optical power query module 200 to uniformly query the service light before and after the cutover. power. The cutover group can be named according to the area where the service is located, or it can be named according to the cutover order. The optical power query module 200 can query the current optical power of the service or the historical optical power of the service when the optical power is queried. The queried optical power value can be set to the reference optical power, and the default reference optical power provided by the network management device can be the current optical power value. The cutover module 300 is configured as: service cutover. The optical power deviation judgment module is configured to: determine whether the service optical power meets the requirement after the service cutover. If the optical power deviation is normal, it is confirmed that the service is normal after the cutover. If the optical power deviation exceeds the normal deviation range, an error message is sent to remind the staff to adjust the service or adjust the amplifier gain. Or adjust the LAC attenuation. The network management system can receive the error prompt information, and can warn the service highlighting red of the optical power deviation exceeding the deviation threshold, so that the cutover personnel can quickly locate the abnormal service and adjust in time.

The network management system may be configured to: display the service to be highlighted according to the error prompt information, and query the current optical power of the service again after adjusting the service by using the optical power query module.

The cutover group module may also be configured to: configure the service to be cut and cut in the cutover group, and save the information of the cutover group; and name the cutover group through the cutover area or the cutover order.
