Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Referring to fig. 1, an application environment diagram of a data synchronization method is shown; in order to ensure that the service is not interrupted when the network equipment fails and ensure the reliability of network transmission, a plurality of routing devices are usually arranged at the core service node of the network; fig. 1 illustrates two devices as an example, that is, a dual-device backup mode includes a primary device and a standby device; the main equipment is used for providing service support, forwarding service flow, and sending service backup information to the standby equipment when a set flow threshold value or a set time threshold value is reached; the standby device is used for receiving the service backup information sent by the main device, and when the main device has a link failure, the standby device is switched to the main device to replace the original main device to provide service support, forward service flow and ensure that the service is not interrupted.
In the process of researching data synchronization, the inventor finds that when the primary equipment breaks down suddenly and the standby equipment is switched to the primary equipment, charging can only be started on the basis of the service backup information of the last backup, and service flow or service time generated between the last backup time and the time of occurrence of the fault cannot be counted, so that service charging errors occur during switching, and the accuracy is low.
Specifically, when the primary device fails, for example, a link failure between the primary device and a user service host, a link failure between the primary device and a core device, some failures of the primary device itself, and the like, the standby device is switched to the primary device; because the backup service information is stored in the standby equipment, the user does not need to dial again, the related charging and authorization information is not lost, the user service is not interrupted, and the network reliability is higher.
However, the backup process usually triggers the backup operation after the network traffic reaches a set traffic threshold or a set time threshold, for example: taking a set time threshold of 5 minutes as an example, the backup operation is assumed to be performed once at 10: 10, the time when the primary device suddenly fails is 10: 12, the time duration from 10: 10 to 10: 12 is 2 minutes, and the time threshold of 5 minutes is not reached, so that the service in the time duration of 2 minutes is not synchronized into the backup device, when the backup device is switched to the primary device, charging can only be started on the basis of the service backup information backed up at the last time (i.e. 10: 10), and the service traffic or service time generated between the last backup time and the failure occurrence time cannot be counted, so that service charging errors occur during switching, and the accuracy is low.
In view of the above problem that when a master device and a slave device in a network node are switched, the service charging accuracy is low, the embodiments of the present disclosure provide a data synchronization method, apparatus, system, network device, and machine-readable storage medium; the technology can be universally applied to network equipment such as switches, routers and gateways, for example: the method is applied to relevant equipment in the BRAS network; the techniques may be implemented in associated software or hardware, as described below by way of example.
In one embodiment, refer to a flow chart of a data synchronization method shown in fig. 2; the method is applied to a first network device, and the first network device and a second network device are mutually a master device and a standby device; the method comprises the following steps:
step S202, if the first network equipment is switched from the main equipment to the standby equipment, recording the charging reference information of the user; the charging reference information includes internet time information and/or internet traffic information, for example, the charging reference information includes only internet time information, or the charging reference information includes only internet traffic information, or the charging reference information includes both internet time information and internet traffic information, which can be specifically selected according to the charging mode of the user service in the actual network.
Step S204, synchronizing the charging reference information with the second network device.
In the method for synchronizing the charging reference information in the embodiment of the present disclosure, triggering of a flow threshold and a time threshold is not required, and after the active/standby switching is performed, an active issuing method, a request-based issuing method, or a method for storing information for an opposite side to read the information by itself may be adopted.
For example, the first network device and the second network device are connected to a plurality of user service hosts, and at time a, the first network device serving as the active device sends service backup information to the second network device serving as the standby device; the service backup information may include the charging reference information, and may also include service data of each user; at time B, the first network equipment is in link failure, the first network equipment is switched to be standby equipment, and the second network equipment is switched to be main equipment; at this time, the first network device records the time when the fault occurs, namely the time B, and the time is used as the charging reference information of each user; and then, synchronizing the charging reference information with the current main equipment, namely the second network equipment, so that the second network equipment carries out service charging statistics on the basis of the charging reference information of each user at the moment B.
By the above manner, the charging reference information between the time a of sending the service backup information and the time B of the occurrence of the fault can be counted; when the user quantity in the network is large, the service flow or the service time sum generated between the time A and the time B is also large, and further a certain economic loss can be saved for a network operator.
In the data synchronization method provided by the embodiment of the present disclosure, if the first network device is switched from the active device to the standby device, the charging reference information of the user is recorded, and then the charging reference information is synchronized with the second network device. In this way, the second network device can obtain more accurate user charging information before the switching of the primary and secondary devices, and reduce charging errors, compared with the service backup information sent when the set flow threshold or the set time threshold is met, thereby reducing the economic loss of network operators.
In another embodiment, a description is given by taking an example where a link failure occurs in an active device; the step of recording the charging reference information of the user if the first network device is switched from the active device to the standby device specifically includes: if the first network equipment is switched to the standby equipment due to the link failure, acquiring a charging reference moment, wherein the charging reference moment is the last charging updating moment and/or the last service data synchronization moment; and recording the charging reference information between the charging reference time and the fault occurrence time.
The last charging update time or the last service data synchronization time can be understood as the latest charging update time or the last service data synchronization time until the fault occurrence time; during specific implementation, the last charging updating time and the last service data synchronization time can be obtained simultaneously, or only one of the last charging updating time and the last service data synchronization time can be obtained; the charging update time or the service data synchronization time may be the same or different. For example, the system may set to perform charging update when the service data is synchronized, where the charging update time is the same as the service data synchronization time; the system can also set the triggering condition of charging update and the triggering condition of service data synchronization to be independent, and at the moment, the charging update time is different from the service data synchronization time.
The step of recording the charging reference information between the charging reference time and the occurrence time of the fault may be implemented in various ways, see a flowchart of another data synchronization method shown in fig. 3; in this embodiment, the step of recording the charging reference information between the charging reference time and the occurrence time of the fault specifically includes: recording the charging reference time and the occurrence time of the link fault as internet access time information in the charging reference information; and/or recording the flow value at the charging reference moment and the flow value at the fault occurrence moment as the internet traffic information in the charging reference information.
As shown in fig. 3, the method comprises the steps of:
step S302, if the first network device is switched to the standby device due to the link failure, obtaining a charging reference time, where the charging reference time is a last charging update time and/or a last service data synchronization time.
Step S304, recording the charging reference time and the occurrence time of the link fault as the internet surfing time information in the charging reference information; and/or recording the flow value at the charging reference moment and the flow value at the fault occurrence moment as the internet traffic information in the charging reference information.
In step S304, the internet access time information and the internet access traffic information may be recorded at the same time, or only the internet access time information is recorded, or only the internet access traffic information is recorded; the internet surfing time information and the internet surfing flow information can be recorded in a form of a table; for example, a table is set for recording the charging reference time and the flow value of the charging reference time, as shown in table 1 below; another table is provided for recording the occurrence time of the link failure and the flow value of the occurrence time of the failure, as shown in table 2 below.
TABLE 1
TABLE 2
Step S306, if receiving the synchronous request of the second network device, sending the charging reference information to the second network device; in the above tables 1 and 2, the internet access time information and the internet access traffic information of two users, user PPPoE1 and user IPoE1, are recorded respectively, and in actual implementation, the above tables 1 and 2 may be sent to the second network device, so that the second network device may calculate the time difference between the occurrence time of the link failure and the charging reference time, and the traffic difference between the occurrence time of the link failure and the charging reference time, and according to the time difference and/or the traffic difference, the charging error between the charging reference time and the occurrence time of the link failure in the second network device is compensated.
In the data synchronization method provided by the embodiment of the present disclosure, if the first network device is switched from the active device to the standby device due to a link failure, the time value and the flow value of the charging reference time and the occurrence time of the link failure are recorded as the internet time information and the internet flow information, and if a synchronization request of the second network device is received, the internet time information and the internet flow information are sent to the second network device. In this way, the second network device can obtain more accurate user charging information before the switching of the primary and secondary devices, and reduce charging errors, compared with the service backup information sent when the set flow threshold or the set time threshold is met, thereby reducing the economic loss of network operators.
See FIG. 4 for a flow chart of another data synchronization method; in this embodiment, the step of recording the charging reference information between the charging reference time and the occurrence time of the fault specifically includes: recording the time difference between the occurrence time of the fault and the charging reference time as the internet surfing time information in the charging reference information; and/or recording the flow difference between the occurrence moment of the fault and the charging reference moment as the internet flow information in the charging reference information. In addition, the step of recording the charging reference information between the charging reference time and the occurrence time of the fault may further include: and recording service data between the charging reference time and the fault occurrence time.
As shown in fig. 4, the method includes the steps of:
step S402, if the first network device is switched to the standby device due to the link failure, acquiring a charging reference time, wherein the charging reference time is a last charging updating time and/or a last service data synchronization time.
Step S404, recording the time difference between the occurrence time of the fault and the charging reference time as the internet surfing time information in the charging reference information; and/or recording the flow difference between the occurrence moment of the fault and the charging reference moment as the internet flow information in the charging reference information.
In step S404, the internet access time information and the internet access traffic information may be recorded at the same time, or only the internet access time information is recorded, or only the internet access traffic information is recorded; the internet surfing time information and the internet surfing flow information can be recorded in a form of a table; for example, a table is set for recording the charging reference time and the flow value of the charging reference time, as shown in table 1 above; another table is provided for recording a time difference between the occurrence time of the fault and the charging reference time and a flow rate difference between the occurrence time of the fault and the charging reference time, as shown in table 3 below.
TABLE 3
The table 1 and the table 3 record the internet access time information and the internet access traffic information of two users, namely the user PPPoE1 and the user IPoE1, respectively, and in actual implementation, the table 1 and the table 3 may be sent to the second network device, so that the second network device directly compensates the charging error between the charging reference time and the occurrence time of the link fault in the second network device according to the time difference and/or the traffic difference.
Step S406, if it is detected that the link with the second network device is normal, pushing the charging reference information to the second network device.
In order to improve the flexibility of the synchronization method of the charging reference information, in practical implementation, the step of synchronizing the charging reference information with the second network device may be implemented by at least one of the following methods:
(1) if a synchronization request of the second network equipment is received, sending the charging reference information to the second network equipment; step S306 described above; the method can be applied to the situation that the link between the first network device and the user service host fails and the link between the first network device and the core device is normal.
(2) If the link between the first network equipment and the second network equipment is detected to be normal, the charging reference information is pushed to the second network equipment; step S406 as above; the method can be applied to a scenario that a link between first network equipment and core equipment fails, when the link between the first network equipment and the core equipment fails, the second network equipment cannot send a synchronization request to the first network equipment, at this time, the first network equipment can detect whether the link between the first network equipment and the core equipment is recovered to be normal or not in a polling mode, and when the link between the first network equipment and the core equipment is recovered to be normal, the charging reference information is pushed to the second network equipment.
In addition, the second network device may further detect the active device through a VRRP (Virtual Router Redundancy Protocol), determine whether a VSRP (Virtual Service Redundancy Protocol) link between the first network device and the second network device is normal, and if the VSRP channel is not passed, periodically poll whether the link is normal; when the link is normal, the charging reference information of the first network device is acquired through a Transmission Control Protocol (TCP) channel.
(3) And storing the charging reference information according to a preset storage mode so that the second network equipment can read the charging reference information. For example, the first network device may store the charging reference information in a set storage interval, and the second network device may read the charging reference information at any time.
In the data synchronization method provided by the embodiment of the present disclosure, if the first network device is switched from the primary device to the standby device due to the link failure, a time difference and a flow difference between a charging reference time and an occurrence time of the link failure are recorded as the internet time information and the internet flow information; the charging reference information can be flexibly synchronized with the second network equipment in various ways; in this way, the second network device can obtain more accurate user charging information before the switching of the primary and secondary devices, and reduce charging errors, compared with the service backup information sent when the set flow threshold or the set time threshold is met, thereby reducing the economic loss of network operators.
In one embodiment, refer to a flow chart of another data synchronization method shown in fig. 5; the method is applied to a first network device, and the first network device and a second network device are mutually a master device and a standby device; the method comprises the following steps:
step S502, if the first network equipment is switched from standby equipment to main equipment, the charging reference information of the user is acquired from the second network equipment; the charging reference information comprises internet surfing time information and/or internet surfing flow information.
In the above embodiment, the first network device corresponds to the second network device to synchronize the charging reference information in multiple ways, and in step S502, the step of obtaining the charging reference information of the user from the second network device may be implemented in one of the following ways, so as to improve the flexibility of the synchronization way:
(1) if the link between the second network equipment and the second network equipment is detected to be normal, sending a synchronization request to the second network equipment, and receiving charging reference information sent by the second network equipment according to the synchronization request;
(2) receiving charging reference information pushed by second network equipment;
(3) and accessing the second network equipment, and reading the charging reference information according to a preset storage mode.
Step S504, the online service of the user is monitored according to the charging reference information.
Users in a network typically purchase online services in a prepaid manner, for example, prepaid according to internet time or prepaid according to internet traffic; when the first network device switched from the standby device to the main device acquires the charging reference information of the user from the second network device, the first network device can acquire the latest charging data of the user, and the first network device can compare the charging data with the prepaid internet time or internet traffic of the user according to the charging data so as to monitor whether the user has the right to enjoy the online service.
In the data synchronization method provided by the embodiment of the present disclosure, if the first network device is switched from the standby device to the active device, the charging reference information of the user is obtained from the second network device, and the online service of the user is monitored according to the charging reference information. In this way, the first network device can obtain more accurate user charging information before the switching of the primary and secondary devices, and reduce charging errors, compared with the service backup information sent when the set traffic threshold or the set time threshold is met, thereby reducing the economic loss of network operators.
In one embodiment, refer to a flow chart of another data synchronization method shown in fig. 6;
step S602, if the link failure of the second network device triggers the first network device to switch from the standby device to the active device, the charging reference information of the user is obtained from the second network device; the charging reference information comprises internet surfing time information and/or internet surfing flow information.
Step S604, obtaining a difference value between the charging reference time and the occurrence time of the fault, where the difference value includes: time difference and/or flow difference; and the charging reference time is the last charging updating time of the second network equipment and/or the last service data synchronization time.
The difference may include a time difference and a flow difference, or only a time difference, or only a flow difference; the last charging updating time or the last service data synchronization time in the charging reference time can be understood as the latest charging updating time or the last service data synchronization time until the fault occurrence time; the step S604 may obtain the last charging update time and the last service data synchronization time at the same time, or obtain only the last charging update time, or obtain only the last service data synchronization time.
After the time difference and/or the flow difference are obtained, the online service of the user can be monitored according to the difference, and the method can be specifically realized by the following steps:
step S606, if the user is in the online state, judging whether the residual charge of the user is larger than the difference value, wherein the residual charge comprises the residual time quantum or the residual flow corresponding to the difference value; if yes, go to step S608; if not, step S610 is performed.
Step S608, the user is kept online.
Step S610, the user is switched to the offline state or the overdraft service state.
Generally, after a user purchases an online service in a prepaid manner, the remaining time amount or the remaining flow of the user may be continuously reduced along with the process of using the online service by the user, and when the remaining time amount or the remaining flow of the user is smaller than the difference, it indicates that the user has completed using the purchased online service before switching the primary device and the secondary device, and at this time, the user is switched to an offline state or an overdraft service state.
In the data synchronization method provided by the embodiment of the present disclosure, if the first network device is switched from the standby device to the active device, the charging reference information of the user is obtained from the second network device, and the service state of the user is maintained or switched according to the charging reference information. In this way, the first network device can obtain more accurate user charging information before the switching of the primary and secondary devices, and reduce charging errors, compared with the service backup information sent when the set traffic threshold or the set time threshold is met, thereby reducing the economic loss of network operators.
