Description

Data synchronization method and device and computer readable storage medium

Technical Field

The embodiment of the application relates to the technical field of communication, and in particular, to a data synchronization method and apparatus, and a computer-readable storage medium.

Background

The management and control system of the operator network is mainly used for managing professional network equipment. And the southbound interface of the management and control system is directly connected with each device. Common southbound interface protocols include Simple Network Management Protocol (SNMP) protocol, network configuration (Netconf) protocol, and the like. For example, the functions of the management and control system include topology management, configuration management, resource management, alarm management, performance management, log management, user management, and the like. Based on the functions, the management and control system can realize management and control of all the layers of the equipment.

In order to realize the management and control of the management and control system on the device, the data such as the device configuration, the state and the like stored on the management and control system must be consistent with the data of the device, and the real-time performance of the data of the device should be ensured. In general, when an initial online device is managed by a management and control system through an SNMP protocol, the data of all devices can be queried once, so as to ensure data synchronization. When a certain state of the subsequent device changes, the device may actively report the state change information in an event trap (trap) message manner. After receiving the trap message reported by the device, the management and control system may update the stored state change information of the device.

However, there is a correlation between the status parameters of different devices, and the devices do not report messages when the status parameters change. Meanwhile, the message reported by the device may not cover all the changed parameters, which brings the problem that the device data stored in the management and control system is not synchronous with the actual data of the device.

Detailed Description

In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in other sequences than those illustrated or described herein. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the embodiments of the application, as detailed in the appended claims.

It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As introduced in the background, the governing system of a carrier network is mainly used to manage the synchronization of time signals/clock signals (also called frequency signals) between time/clock server devices and transmission devices in the network. The Time signals transmitted among the devices in the synchronous network mainly include Precision Time Protocol (PTP) signals, real-Time clock synchronization signals (1pulse per second and Time of date and 1pps +) tod signals, and the transmitted frequency signals mainly include 2 Mbit/s (Mbit/s), 2 mhz (hz), synchronous ethernet (sync e) signals, etc. The transmission devices in the network can transmit time signals and frequency signals transmitted one by one, so that the time synchronization and the frequency synchronization of the devices in the whole network are realized.

In one example, as shown in fig. 1, a schematic diagram of the transmission of time signals in a network is shown. The solid line in fig. 1 is the current actual transmission path of the PTP signal, and the dotted line is the shadow transmission path of the PTP signal.

It should be noted that, in the embodiment of the present application, the network is a synchronous network. The management and control system in the network can directly correspond to each device through the southbound interface. Common southbound interface protocols include SNMP, netconf protocols, and the like. The management and control system mainly has the functions of topology management, configuration management, resource management, alarm management, performance management, log management, user management and the like, and realizes the management and control of all layers of equipment.

The SNMP protocol adopts a special form of a Client (Client)/Server (Server) model: the agent/management station model. The management and maintenance of the network by the management system are completed by the interaction between the management workstation and the SNMP agent. Each SNMP gateway is used for receiving query information from an SNMP management workstation (a main agent) and providing information related to the query information. The query information is used to query information in the MIB. The MIB contains parameters of all agent processes that can be queried and modified. For example, the structure of the MIB may be as shown in fig. 2.

Further, in order to realize information interaction before the management process and the agent process of the SNMP, as shown in fig. 3, the SNMP protocol defines 5 messages:

1. get request (get-request) operation: one or more parameter values are extracted from the agent process.

2. Get the next request (get-next-request) operation: the next parameter value of the one or more parameters is retrieved from the broker process.

3. Set-request (set-request) operation: one or more parameter values of the agent process are set.

4. Get response (Get-response) operation: the returned one or more parameter values. An operation is issued by the proxy process.

5. Trap operation: the agent process sends out message to inform the management process that some things happen.

The above-mentioned operations 1-3 are issued by the management process to the agent process, and 4 and 5 are issued by the agent process to the management process. The 3 operations sent by the management process adopt 1 6 ports of a user datagram protocol (UPD). Trap operations issued by the proxy process use the 1 6 port of the UDP. Because different port numbers are adopted for transceiving, the management and control system can simultaneously serve as a management process and a proxy process.

Further, in order to implement the management and control of the device by the management and control system, it is necessary to ensure that data such as configuration and state of the device stored by the management and control system is consistent with actual data of the device, and real-time performance of the data should be ensured. When the management and control system manages the initially online equipment through the SNMP protocol, the data of the managed equipment can be inquired in a full amount so as to ensure the consistency of the data. When a certain state of the subsequent device changes, the device may report to the network management and control system by notifying an event trap. After receiving the trap message, the management and control system may analyze the corresponding parameter in the trap message and update the database of the management and control system itself.

However, there is a correlation between many state parameters on the device, and there is a correlation between some parameters of the management and control system itself and the state parameters of the device, and not all the state parameters of the device report messages when they are changed. Normally, a device reports a message only when some relatively important event or failure occurs. However, the message reported by the device may not cover all the parameters that are changed. In addition, when the state of a certain device changes, the state of other devices can also be changed, which brings the problem that the data of the management and control system and the device are inconsistent.

In a possible implementation manner, the management and control system may actively query the operation data of the device according to a preset time period (e.g., 1 day). And when the operating data of the equipment is not consistent with the stored operating data, updating the stored equipment data. However, the real-time performance of this method is poor, and the real-time synchronization of the data of the synchronization management and control system and the device cannot be achieved.

In view of this, an embodiment of the present application provides a data synchronization method, which is used to ensure data synchronization between a management and control device and a device. The management and control device receives a plurality of notification events in a first time period, and determines one or more parameter instances associated with each object instance in the plurality of notification times by querying a preset state association library. Then, the management and control device may merge one or more parameter instances associated with the multiple object instances to obtain a parameter instance set. Finally, the management and control device may query the parameter value of each parameter instance in the parameter instance set, and update the parameter value in the database according to the parameter value of each parameter instance, so as to synchronize the parameter value stored in the database with the actual data of the device.

The method provided by the embodiment of the application is described in detail below with reference to the attached drawings.

It should be noted that, the network system described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation to the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows, with the evolution of the network system and the appearance of other network systems, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

In order to facilitate clear description of technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish identical items or similar items with substantially the same functions and actions. For example, the first data transmission policy and the second data transmission policy are only for distinguishing different data transmission policies, and the order of the data transmission policies is not limited. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

It is noted that, in the present application, words such as "exemplary" or "for example" are used to mean exemplary, illustrative, or descriptive. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In this application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a alone, A and B together, and B alone, wherein A and B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

The following describes a data synchronization method provided in an embodiment of the present application with reference to a network architecture shown in fig. 6.

Fig. 6 provides a data synchronization method applied to a management and control device according to an embodiment of the present application, where the management and control device may be the management and control apparatus in fig. 4. As shown in fig. 6, the method includes:

s601, receiving a plurality of notification events of a first time period.

And the duration of the first time period is less than or equal to the preset duration. For example, the first time period may be 30 seconds(s), 20s, and so on. A notification event is used to notify an object instance of a change in parameter values. The object instance may be a network element, a link, a board, a port, a time signal, a frequency signal, a clock (frequency) tracking status, a time tracking status, etc. The object instance may also be an example of a MIB node parameter of the device. Such as whether the board is in place. The object instance may also be a parameter instance of the governing device. For example, the board status color of the device block diagram of the management and control device may be used.

In a possible implementation manner, when a certain device detects that an operation parameter changes, a notification event may be reported to the management and control device. Accordingly, the management and control device may receive the notification event reported by the device.

In one example, when the managing device communicates with the device using the SNMP protocol, the device may send a notification event to the managing device in the form of a trap message.

In another possible implementation manner, when a certain device is degraded, a degradation event may be reported to the management and control device. Accordingly, the management and control device may receive the degradation event reported by the device.

It should be noted that the degradation event may refer to an abnormal state of the device or an abnormal operation parameter. For example, when the current tracking state of the device is unlocked (a type of device degradation), a trap message for notifying the current tracking state of the device is unlocked may be reported to the management and control device. The tracking state losing lock means that the device cannot acquire a frequency signal from the last-hop device.

S602, determining one or more first parameter instances associated with each object instance according to a preset state management database.

The preset state association database comprises a plurality of object instances and state association relations between each object instance and a plurality of parameter instances. The parameter instance may or may not be the same as the object instance. For example, when an object instance is a device that is out-of-lock in the current tracking state, the associated parameter instance may be the next hop of the device that is out-of-lock in the current tracking state. For another example, when an object instance is a board is not in place, the parameter instance associated with the object instance may be a port exception for the board.

The preset state management database may be preconfigured for the management and control device, and may also be generated by the management and control device according to an association relationship among a plurality of devices, without limitation. In particular, reference may be made to the ensuing description.

The state association relationship between the object instance and the multiple parameter instances can mean that when the state of the object instance changes, the state change of the multiple parameter instances can be triggered. However, when the states of the plurality of parameter instances change, the state change of the object instance may be triggered or may not be triggered.

In one example, two parameter instances having an associative relationship in the database are associated for a preset state. The association between the two parameter instances may be a one-way relationship or a two-way relationship.

The one-way relationship may refer to that when the state of one parameter instance (denoted as parameter instance 1) of the two parameter instances changes, the state of the other parameter instance (denoted as parameter instance 2) may be triggered to change. However, the change in state of parameter instance 2 cannot trigger the change in state of parameter instance 1. The bidirectional relationship can be changed into a state change of the parameter instance 2, which can be triggered when the state of the parameter instance 1 is changed. Meanwhile, the state change of the parameter example 2 can trigger the state change of the parameter example 1.

In one possible implementation, in the preset state association database, a plurality of parameter instances may be associated in a topological manner.

For example, as shown in fig. 7, the preset state management database may include a plurality of parameter instances, which are parameter instance 3, parameter instance 4, parameter instance 5, parameter instance 6, and parameter instance 7. The association relationship between the multiple parameter instances may be as shown in fig. 7.

In fig. 7, the association between parameter instance 4 and parameter instance 3, and between parameter instance 4 and parameter instance 5 are one-way relationships. The association between the parameter instance 5 and the parameter instance 6, and the association between the parameter instance 6 and the parameter instance 7 are bidirectional relationships. That is, when the state of parameter instance 5 changes, a change in the state of parameter instance 6 may be triggered, and a change in the state of parameter instance 7 may also be triggered.

Further, the parameter instances have constraint relationships. The constraint relationship is used to characterize the positional relationship between the parameter instances. For example, the constraint relationship may include the opposite ports located on the same device, belonging to the same port, located on the same board, and being the same link.

For example, as shown in FIG. 7, the constraint relationship between parameter instance 4 and parameter instance 3 is located in the same device. The constraint relationship between the parameter instance 4 and the parameter instance 5 is the same port. The constraint relationship between the parameter instance 5 and the parameter instance 6 is located on the same board. The constraint relationship between parameter instance 6 and parameter instance 7 is the opposite port of the same link.

In an example, when the management and control device receives a notification event for notifying that the parameter value of the parameter instance 5 (at this time, the parameter instance 5 is an object instance) is changed, the management and control device may determine that the parameter instance associated with the parameter instance 5 includes the parameter instance 6 and the parameter instance 7 according to the association relationship shown in fig. 7.

In another example, when the time of notification received by the management and control device is used to notify that the parameter value of the parameter instance 4 (at this time, the parameter instance 4 is the object instance) changes, the management and control device may determine, according to the association relationship shown in fig. 6, that the parameter instances associated with the parameter instance 4 include the parameter instance 3, the parameter instance 5, the parameter instance 6, and the parameter instance 7.

S603, when coincident parameter instances exist in the one or more first parameter instances corresponding to the multiple object instances, combining the one or more parameter instances corresponding to the multiple object instances to obtain a first parameter instance set.

The first parameter instance set may include first parameter instances corresponding to the merged multiple object instances.

For example, the example in S604 described above is combined. The parameter instances which are determined by the management and control device and are associated with the parameter instance 5 comprise a parameter instance 6 and a parameter instance 7, and the parameter instances which are determined by the management and control device and are associated with the parameter instance 4 comprise a parameter instance 3, a parameter instance 5, a parameter instance 6 and a parameter instance 7. The first set of parameter instances comprises parameter instance 2, parameter instance 5, parameter instance 6 and parameter instance 7. That is, the management and control device may perform deduplication processing on one or more parameter instances corresponding to the multiple object instances. In this manner, the number of parameter instances for subsequent queries may be reduced.

S604, inquiring the parameter value of each parameter instance in the first parameter instance set in the second time period, and replacing the parameter value of each parameter instance in the first parameter instance set stored in the database with the parameter value of each parameter instance in the second time period.

Wherein the second time period is after the first time period. The parameter value of the parameter instance in the second time period may refer to state information, parameter size, and the like of the parameter instance in the second time period. The database may refer to a pre-configured by the governing device. The database is used for storing the operation data of the equipment.

In a possible implementation manner, after the management and control device determines the first parameter instance set, information of a device corresponding to each parameter instance may be determined. Then, the management and control device may send query information to the device corresponding to each parameter instance. The query information is used to query parameter values of the parameter instance over the second time period. The device may send the parameter values of the parameter instance to the managing device in the form of a response message after receiving the query information from the managing device. Therefore, the management and control device can inquire the parameter value of the parameter instance.

It should be noted that, the parameter instance may refer to a device or a part of a device (e.g., version, port). Therefore, the management and control device may determine the device corresponding to the parameter instance according to the parameter instance. The notification event may also include information about the device to which the parameter instance corresponds. Therefore, the management and control device can acquire the information of the device corresponding to the parameter instance according to the notification event.

Further, after the governing device queries the parameter value of each parameter instance in the first parameter instance set, the parameter value of each parameter instance stored in the database may be replaced with the parameter value in the second time period. Therefore, the synchronization of the parameter values stored by the management and control equipment and the parameter values of the equipment is ensured.

Based on the technical scheme of fig. 6, when the management and control system receives a change in the parameter value of multiple instances, it may determine multiple parameter instances associated with the multiple instances by querying a state association knowledge gallery including the multiple instances having a state association relationship, and merge the multiple parameter instances to remove overlapped parameter instances. Therefore, the management and control device can respectively inquire the current parameter values of the parameter instances after the duplication removal. Then, the management and control system may replace the stored parameter values of the multiple parameter instances with the obtained current parameter values of the multiple parameter instances, so that the synchronicity between the data of the multiple parameter values stored in the management and control system and the data of the parameter instances of the multiple devices to be managed is ensured.

In some embodiments, as shown in fig. 8, after S801 described above, the method further includes S801 and S802.

S801, analyzing each notification event to obtain a parameter value of an object example corresponding to each notification event.

Wherein the notification event may include a parameter value of the object instance for a first time period. After receiving the notification event, the management and control device may parse the notification event to obtain a parameter value of the object instance.

S802, updating the database according to the parameter value of the object instance corresponding to each notification event.

Updating the database may refer to replacing the parameter value stored in the database before the first time period with the parameter value of the object instance included in the notification event. As such, overall, accurate synchronization may be included that governs data synchronicity from device to device.

Based on the technical scheme shown in fig. 8, the management and control device may directly analyze the notification event to obtain parameter values of the multiple object instances, and update the parameter values of the object instances in the database. Thus, the synchronicity of the parameter values of the object instance of the management device with the actual parameter values of the device can be ensured.

In some embodiments, when the object instance in the multiple notification events is further associated with the managing device, the managing device may further directly obtain the parameter value of itself, and update the parameter value related to the managing device in the database.

In some embodiments, the preset state association database may be preconfigured for the governing device. For example, maintenance personnel may be entered into the regulating device. The preset state management database may be autonomously generated for the management and control device.

For example, the management and control device may determine, through testing, an association relationship between multiple parameter instances. For example, for the parameter instance 1 and the parameter instance 2, the management and control device may control the device in which the parameter instance 1 is located to change the state of the parameter instance 1. Then, the management and control device may inquire whether the state of the parameter instance 2 changes within a preset time period. When the state of the parameter instance 2 changes, the parameter instance 1 and the parameter instance 2 are shown to be in an association relationship.

Further, in order to determine whether the association relationship between the parameter instance 1 and the parameter instance 2 is a one-way relationship or a two-way relationship, the control device may further continue to control the device in which the parameter instance 2 is located to change the state of the parameter instance 2. Then, the management and control device may inquire whether the state of the parameter instance 1 changes within a preset time period. When the state of the parameter instance 1 changes, the correlation between the parameter instance 1 and the parameter instance 2 is a bidirectional relationship; when the state of the parameter instance 1 is not changed, the association between the parameter instance 1 and the parameter instance 2 is a one-way relationship. The one-way relationship is a change in state of parameter instance 1, which can trigger a change in state of parameter instance 2.

Based on the instance, the governing device may determine an associative relationship between multiple parameter instances. That is, a preset state association database may be determined.

The preset state association database provided in the embodiment of the present application is described below with reference to specific examples.

The preset state association database may also be referred to as a state association knowledge gallery. The preset state association database is a directed graph. Each node in the graph represents a specific object instance of a state parameter. The edges in the graph represent the relationship between two object instances. Edges may be unidirectional or bidirectional.

When the change of one object instance A causes the change of another object instance B and the change of the object instance B does not cause the change of the object instance A, the two object instances are considered to have a relationship, and the edge is unidirectional A- > B. When either of the object instances A and B changes, the other changes, the edge is a bidirectional A < - > B.

It should be noted that, in the embodiment of the present application, the preset state association database is configurable. Any edge in the preset state association database at least comprises 4 characteristics of an object instance A, an object instance B, an influence relationship between the object instance A and the object instance B, and a constraint condition that a relationship exists between the object instance A and the object instance B.

In one example, a PTP input signal status change (e.g., loss of PTP input) of an 8-slot 1 port of a device may cause a change in the source status of the current tracking time of the same device. Meanwhile, a PTP signal input signal state change of an 8-slot 1 port of the device may also cause a PTP signal port state change (e.g., a slave changes to a fault) in the port.

In addition, a PTP signal port state change of the 8 slot 1 port of the device may also cause a PTP signal port state change in the 8 slot 2 port on the same board of the device (e.g., master (slave) to slave). Meanwhile, the state change of the PTP signal port in the 8 slot 2 port of the device may cause the state change of the PTP signal port in the opposite port of the other device directly connected to the 8 slot 2 port (for example, passive port is changed into master). The following 4 features exist for this example.

Feature 1, PTP input signal changes in port- > the device currently tracks time source changes. The constraints are the same device.

Feature 2, PTP input signal change in port- > PTP signal port state change in port. The constraint is the same port.

Feature 3, PTP signal port state change in port-PTP signal port state change in port < - > PTP signal port state change in port. The constraint conditions are other ports of the same board card.

Feature 4, PTP signal port state change in port-PTP signal port state change in port < - > PTP signal port state change in port. The constraint is the same link opposite end port.

Based on the above-mentioned 4 features, the association relationship in the preset state database can be shown in fig. 9.

In yet another example, when a link is down, it may cause the status of the ports on both ends of the link to change. This example has the features: link down- > port status changes to off (down). The constraint is the ports on both ends of the same link.

In one possible embodiment, as shown in fig. 10, the present application provides a data synchronization method, which includes S1001 to S1006.

And S1001, when the state of the equipment is changed, the equipment generates and sends a notification event to the management and control equipment. Accordingly, the policing device receives notification events from the device.

The notification event may be one or a fragment of an SNMP trap event message.

S1002, the management and control device analyzes the received notification event to obtain a parameter value of an object instance in the notification event, and updates the stored state parameter of the device according to the state parameter.

S1003, the management and control equipment queries a preset state association database and determines a first parameter instance associated with the object instance.

Wherein, the first parameter instance comprises an instance of the device and an instance of the control device.

S1004, the management and control device inquires a first parameter instance corresponding to each object instance in the multiple notification events in a preset time period, and merges the first parameter instances corresponding to each object instance in the multiple notification events to obtain a merged parameter instance set.

For example, device a and device B are connected by the same link. The clock of device B is based on the output SyncE signal of device a. The preset state database stores the incidence relation including:

1. device a currently tracks out-of-lock- > device a degrades the ethernet synchronization information channel (ESMC) value of the sync signal in the output port. The constraint condition is the same equipment;

2. the value of the SyncE signal ESMC in the output port of device a deteriorates < - > the value of the SyncE signal ESMC in the input port of device B deteriorates. The constraint is a SyncE signal in the same link.

3. The value of the SyncE signal ESMC in the input port of device B degrades < - > device B currently tracks the clock quality degradation. The constraints are the same device.

In one example, when the management and control device receives a notification event 1 that the device a reports that the current tracking state of the device a is out of lock and a notification event 2 that the device B reports that the current tracking clock quality of the device is degraded, the time interval between the notification event 1 and the notification event 2 is not more than 30s.

The managing device may query, via the preset state management database, an ESMC value degradation instance of the SyncE signal in the output port of device a (the ESMC value represents the frequency quality of the SyncE signal), an ESMC value degradation instance of the SyncE signal in the input port of device B, and a current trace clock quality degradation instance of device B.

The management and control device may query an ESMC value degradation instance of the SyncE signal in the input port of device B and an ESMC value degradation instance of the SyncE signal in the output port of device a through a preset state management database.

Thus, the policing device may merge 2 instances of ESMC value degradation of the SyncE signal in the output port of device a into 1, merge 2 instances of ESMC value degradation of the SyncE signal in the input port of device B into 1, and merge 2 instances of current tracking clock quality degradation of device B into 1.

S1005, inquiring the parameter value of each parameter instance in the merged parameter instance set by the management and control equipment.

In one example, the management and control device may actively query the parameter value of each parameter instance through SNMP get-request. The device where the parameter instance is located can return the current real-time parameter value of the queried parameter instance through SNMP get-response. After receiving the SNMP get-response, the management and control device can update the database of the management and control device.

The parameter example for managing and controlling the equipment query comprises the following steps: the current trace status of device a, the ESMC value of the SyncE signal in the output port of device a, the ESMC value of the SyncE signal in the input port of device B, the current trace clock quality of device B.

And S1006, the management and control equipment updates the parameters displayed on the front-end display interface and the parameter values in the database according to the inquired parameter values of the parameter examples.

It should be noted that, for implementation of S1001 to S1006, reference may be made to the description of the foregoing embodiment, and details are not repeated.

Based on the technical scheme of fig. 10, the real-time synchronization consistency between the data stored in the management and control system device and the data of the device can be ensured based on the preset state association database. Therefore, the network management reliability is improved, and the operation and maintenance efficiency is improved.
