In general, the dual activity center based data processing device may be a terminal device, such as a computer device.

The following description will be made taking a computer device as an example of a main body for executing a data processing method based on a dual active center. Referring to fig. 1, the data processing method based on dual active centers specifically includes:

s101, receiving user data through a network.

The data processing method based on the double living centers can be used for ticket data processing of rail transit, and ticket data can be understood as tickets purchased when passengers take the rail transit. The user data may be understood as inbound data and outbound data of the passenger in the ticket data, and the corresponding fare of the passenger may be calculated by performing service processing based on the inbound data and the outbound data. The embodiment provides that the first data processing center, the second data processing center and the data backup center are arranged to process ticket data, so that the ticket data is processed continuously in the whole time period, and the operation business can be conveniently and smoothly carried out.

The first data processing center, the second data processing center and the data backup center are respectively arranged in three different machine rooms, wherein the first data processing center and the second data processing center are respectively arranged in different geographic positions, and the data backup center can be selected from the different machine rooms which are arranged in the same geographic position with the first data processing center or the second data processing center. It should be noted that the distance between the three machine rooms is below 50KM to maintain good network performance quality.

The first data processing center, the second data processing center and the data backup center are connected through an SDN (software defined network) networking structure, a network link among the first data processing center, the second data processing center and the data backup center can adopt a bare optical fiber or a backbone network, namely an optical transmission network, the network bandwidth is more than 10Gbps, and the delay time is less than 2 ms.

In one embodiment, the first data processing center, the second data processing center, and the data backup center may receive user data via an optical transport network when interconnected via a backbone network. Fig. 2 is a schematic diagram of a backbone all-line network provided in an embodiment of the present application, and referring to fig. 2, backbone network 10 includes a first layer switch 101, a first optical transport network 102, a second layer switch 103, and a second optical transport network 104. User data is received through the first layer switch 101, is transmitted to the second layer switch 103 through the first optical transmission network 102 after being subjected to data exchange processing, and is subsequently transmitted through the second optical transmission network 104 after being subjected to data exchange processing through the second layer switch 103. Illustratively, the first tier switch 101 is an SC switch and the second tier switch 103 is an LC switch.

The above-mentioned, carry on the receiving of user data through the optical transmission network, realize the high-capacity and high-speed data transmission, have raised the overall working efficiency of the business data processing; and the optical transmission network can realize flexible network management and control, and provides network transmission guarantee for the dual-active center.

S102, under the condition that the user data is confirmed to be processed by the first data processing center through a preset load balancing strategy, the user data is used as the first user data to be sent to the first data processing center.

The first data processing center can be understood as a main data center, the second data processing center can be understood as a standby data center, and in order to improve the use rate of the second data processing center serving as a standby, the embodiment confirms that user data is processed by the first data processing center or processed by the second data processing center through a preset load balancing strategy, so that the first data processing center and the second data processing center serve as dual-active centers to participate in service processing, thereby avoiding resource waste caused by the fact that the existing standby data center does not participate in normal service processing.

In case that the user data is confirmed to be processed by the first data processing center through a preset load balancing policy, the user data is transmitted as the first user data to the first data processing center through a network (e.g., an optical transmission network). The first data processing center comprises at least one first server, and the user data is sent to the first server corresponding to the first data processing center as first user data through a network (such as an optical transmission network) under the condition that the user data is confirmed to be processed by the first data processing center through a preset load balancing strategy. Fig. 3 is a schematic diagram of a dual activity center-based data processing system according to an embodiment of the present application, and referring to fig. 3, it is assumed that the first data processing center 11 includes three first servers, namely, a first server a, a first server B, and a first server C. In the case that it is confirmed that the user data is processed by the first data processing center 11 through a preset load balancing policy, the user data is transmitted as first user data to the first server a, the first server B, or the first server C corresponding to the first data processing center 11 through a network (e.g., an optical transmission network).

In an embodiment, referring to fig. 3, the optical transmission network sends the first user data to the first data processing center 11 through at least two communication links, so that when any communication link fails, data can be transmitted through other communication links, and reliability of data transmission is improved.

In the above-mentioned case, when the user data is confirmed to be processed by the first data processing center through the preset load balancing policy, the user data is sent as the first user data to the first server corresponding to the first data processing center through the network (for example, an optical transmission network), so as to implement load balancing, reasonably arrange the corresponding load (the first server) to receive the user data, and improve the load balancing degree of the overall system, thereby improving the overall working efficiency of service processing.

S103, the first data processing center performs service processing according to the first user data and the stored service data to obtain first service data.

Based on the ticket data of the passenger, the user data may be either inbound data or outbound data. And under the condition that the first user data is inbound data, the first data processing center directly carries out service processing according to the first user data after receiving the first user data to obtain corresponding first service data. In the case that the first user data is outbound data, based on the data processing method based on the dual-activity center provided by the embodiment, the first data processing center stores corresponding inbound data based on synchronization of service data, so that after receiving the first user data, the first data processing center performs service processing according to the first user data and the stored service data to obtain corresponding first service data; the first service data obtained at this time should be corresponding ticket settlement data. After the first data processing center receives the first user data, the first data processing center performs service processing according to the first user data and the stored service data, so that the ticket service data are synchronized, and the continuity of the service processing of the ticket service data is improved.

In an embodiment, referring to fig. 3, the first data processing center 11 includes a first core switch 111, a second core switch 112, and at least one first server, and in the case that it is confirmed that user data is processed by the first data processing center 11 through a preset load balancing policy, the user data is sent as first user data to a first server corresponding to the first data processing center 11 through a network (e.g., an optical transport network), and first sub-data is obtained by performing first service processing according to the first user data and stored service data through the corresponding first server, and is transmitted to the first core switch 111 or the second core switch 112. It should be noted that the transmission may be performed to the first core switch 111 or the second core switch 112 according to the actual situation, for example, in a case where the first core switch 111 and the second core switch 112 are both normal, a transmission in turn may be used, for example, the transmission is performed to the first core switch 111 for the first time, the transmission is performed to the second core switch 112 for the second time, and so on. Alternatively, when one of the core switches fails, the first sub data is transferred to another core switch in a normal state, for example, when the first core switch 111 fails, and the first sub data is transferred to the second core switch 112.

For example, referring to fig. 3, in case that it is confirmed that user data is processed by the first data processing center 11 through a preset load balancing policy, the user data is transmitted as first user data to the first server a, the first server B, or the first server C corresponding to the first data processing center 11 through a network (e.g., an optical transmission network). For example, the user data is sent as first user data to a first server a corresponding to the first data processing center 11 through an optical transmission network, and then first service processing is performed by the first server a according to the first user data and the stored service data, so as to obtain first sub-data. The first server a transmits the first sub data to the first core switch 111 or the second core switch 112.

In the case where the first server transmits the first sub-data to the first core switch 111, the first core switch 111 performs a first data exchange process on the first sub-data to obtain first exchange data, and transmits the first exchange data to the first edge switch 113. The first data exchange process is a process of exchanging core data. The first edge switch 113 performs a second data exchange process on the first exchange data to obtain first service data. The second data exchange process is a process of exchanging edge data.

In the case that the first server transmits the first sub data to the second core switch 112, the second core switch 112 performs a third data switching process on the first sub data to obtain second switching data, and transmits the second switching data to the second edge switch 114. The third data exchange process is a process of exchanging core data. The second edge switch 114 performs fourth data switching processing on the second switching data to obtain the first service data. The fourth data exchange process is a process of exchanging edge data.

In the first data processing center, the first core switch or the second core switch is used for exchanging core data, and the first edge switch and the second edge switch which are low in price relative to the core switch are used for exchanging edge data, so that the overall cost investment of the first data processing center is saved.

S104, the first data processing center synchronizes the first service data to the second data processing center and the data backup center.

After the first data processing center performs service processing according to the first user data and the stored service data to obtain the first service data, the first data processing center synchronizes the first service data to the second data processing center and the data backup center, so that when the second data processing center receives the second user data for processing, the second data processing center can perform service processing based on the second user data and the stored service data (such as the first service data), service interruption is avoided, the connectivity of the first data processing center and the second data processing center is improved, the first data processing center and the second data processing center can participate in service data processing, the utilization rate of the standby data center (such as the second data processing center) is improved, and the overall resource utilization rate in the service processing process is improved.

In an embodiment, the data backup center plays a role of data backup, when the first data processing center or the second data processing center fails, the corresponding service data can be synchronized to the corresponding first data processing center or the second data processing center through the data backup center after the failure is eliminated, so that the safety and the continuity of the service data are improved, the corresponding service processing can be continuously performed based on the synchronized service data after the failure is eliminated, and the overall working efficiency of the service processing can be improved.

In one embodiment, referring to fig. 3, the first data processing center 11 includes a first edge switch 113 and a second edge switch 114, the second data processing center 12 includes a third edge switch 123 and a fourth edge switch 124, and the data backup center 13 includes a fifth edge switch 133 and a sixth edge switch 134; wherein the first edge switch 113 is communicatively coupled to the third edge switch 123 and the fifth edge switch 133, and the second edge switch 114 is communicatively coupled to the fourth edge switch 124 and the sixth edge switch 134. The first data processing center 11 transmits the first service data to the third edge switch 123 of the second data processing center 12 and the fifth edge switch 133 of the data backup center 13 through the first edge switch 113 to achieve data synchronization. Alternatively, the first data processing center 11 transmits the first service data to the fourth edge switch 124 of the second data processing center 12 and the sixth edge switch 134 of the data backup center 13 through the second edge switch 114 to achieve data synchronization. When detecting that the communication link corresponding to the first edge switch 113 has a fault, the first data processing center 11 sends the first service data to the fourth edge switch 124 of the second data processing center 12 and the sixth edge switch 134 of the data backup center 13 through the second edge switch 114, so as to achieve service data synchronization. Or, when detecting that the communication link corresponding to the second edge switch 114 has a failure, the first data processing center 11 transmits the first service data to the third edge switch 123 of the second data processing center 12 and the fifth edge switch 133 of the data backup center 13 through the first edge switch 113 to achieve service data synchronization. In the above, two edge switches are respectively disposed in the first data processing center 11, the second data processing center 12 and the data backup center 13, and service data are synchronized correspondingly through two communication links, and when any communication link fails, service data can be synchronized through another communication link, so that reliability and safety of data synchronization are improved, and orderly performance of overall service processing is ensured, and further reliability of service processing of the whole system is improved.

S105, when the user data is confirmed to be processed by the second data processing center through a preset load balancing strategy, the user data is sent to the second data processing center as second user data.

In case it is confirmed that the user data is processed by the second data processing center through a preset load balancing policy, the user data is transmitted as second user data to the second data processing center through a network (e.g., an optical transmission network). The second data processing center comprises at least one second server, and the user data is sent to the second server corresponding to the second data processing center as second user data through a network (such as an optical transmission network) under the condition that the user data is confirmed to be processed by the second data processing center through a preset load balancing strategy. Referring to fig. 3, it is assumed that the second data processing center 12 includes three second servers, namely, a second server C, a second server D, and a second server E. In the case that the processing of the user data by the second data processing center 12 is confirmed by the preset load balancing policy, the user data is transmitted as the second user data to the second server C, the second server D, or the second server E corresponding to the second data processing center 12 through the optical transmission network.

In an embodiment, referring to fig. 3, the optical transport network sends the second user data to the second data processing center 12 through at least two communication links, so that when any communication link fails, data can be transmitted through other communication links, and reliability of data transmission is improved.

In the above, when the user data is confirmed to be processed by the second data processing center through the preset load balancing policy, the user data is sent as the second user data to the second server corresponding to the second data processing center through the network (for example, an optical transmission network), so as to realize load balancing, reasonably arrange the corresponding load (the second server) to receive the user data, and improve the load balancing degree of the whole system, thereby improving the whole working efficiency of service processing.

According to the method, the device and the system, the user data are determined to be processed by the first data processing center or the second data processing center through the load balancing strategy, so that the second data processing center serving as a standby can also participate in normal service processing, the problem of low resource utilization rate caused by the fact that the standby center does not participate in the service processing under the normal use condition of the main center can be avoided, the utilization rate of the standby second data processing center is improved, and therefore the overall resource utilization rate of data processing is improved.

S106, the second data processing center performs service processing according to the second user data and the stored service data to obtain second service data.

Based on the ticket data of the passenger, the user data may be either inbound data or outbound data. And under the condition that the second user data is inbound data, the second data processing center directly carries out service processing according to the second user data after receiving the second user data to obtain corresponding second service data. In the case that the second user data is outbound data, based on the data processing method based on the dual-activity center provided by the embodiment, the second data processing center stores corresponding inbound data based on synchronization of service data, so that after receiving the second user data, the second data processing center performs service processing according to the second user data and the stored service data to obtain corresponding second service data; the second service data obtained at this time should be corresponding ticket settlement data. After the second data processing center receives the second user data, the second data processing center performs service processing according to the second user data and the stored service data, so that the ticket service data are synchronized, and the continuity of the service processing of the ticket service data is improved.

In an embodiment, referring to fig. 3, the second data processing center 12 includes a third core switch 121, a fourth core switch 122 and at least one second server, and when it is confirmed that the user data is processed by the second data processing center through a preset load balancing policy, the user data is sent as second user data to a second server corresponding to the second data processing center 12 through a network (e.g., an optical transport network), and the first service processing is performed according to the second user data and the stored service data through the corresponding second server, so as to obtain second sub-data, and the second sub-data is transmitted to the third core switch 121 or the fourth core switch 122. It should be noted that, the transmission may be performed to the third core switch or the fourth core switch 122 according to the actual situation, for example, in the case where the third core switch 121 and the fourth core switch 122 are both normal, a transmission in turn may be used, for example, the transmission is performed to the third core switch 121 for the first time, the transmission is performed to the fourth core switch 122 for the second time, and so on. Alternatively, when one of the core switches fails, the second sub data is transferred to another core switch in a normal state, for example, the third core switch 121 fails, and the second sub data is transferred to the fourth core switch 122.

For example, referring to fig. 3, in case that it is confirmed that the user data is processed by the second data processing center through a preset load balancing policy, the user data is transmitted as second user data to the second server C, the second server D, or the second server E corresponding to the second data processing center 12 through a network (e.g., an optical transmission network). For example, the user data is sent as second user data to a second server C corresponding to the second data processing center 12 through the optical transport network, and then second service processing is performed by the second server C according to the second user data and the stored service data, so as to obtain second sub-data. The second server C transmits the second sub data to the third core switch 121 or the fourth core switch 122.

In the case where the second server transmits the second sub data to the third core switch 121, the third core switch 121 performs a fifth data exchange process on the second sub data to obtain third exchange data, and transmits the third exchange data to the third edge switch 123. The fifth data exchange process is a process of exchanging core data. The third edge switch 123 performs sixth data exchange processing on the fifth exchange data to obtain second service data. The sixth data exchange process is a process of exchanging edge data.

In the case where the second server transmits the second sub data to the fourth core switch 122, the seventh data exchange process is performed on the second sub data through the fourth core switch 122 to obtain fourth exchange data, and the fourth exchange data is transmitted to the fourth edge switch 124. The seventh data exchange process is a process of exchanging core data. The fourth edge switch 124 performs eighth data exchange processing on the fourth exchange data to obtain second service data. The eighth data exchange process is a process of exchanging edge data.

In the second data processing center, the core data is exchanged through the third core switch or the fourth core switch, and the edge data is exchanged through the third edge switch and the fourth edge switch which are low in price relative to the core switch, so that the overall cost investment of the second data processing center is saved.

And S107, the second data processing center synchronizes the second service data to the first data processing center and the data backup center.

The second data processing center performs service processing according to the second user data and the stored service data, and after the second service data is obtained, the second data processing center synchronizes the second service data to the first data processing center and the data backup center, so that when the first data processing center receives the first user data processing, the first data processing center can perform service processing based on the first user data and the stored service data (such as the second service data), service interruption is avoided, the linkage of the first data processing center and the second data processing center is improved, the first data processing center and the second data processing center can participate in service data processing, the utilization rate of a standby data center (such as the second data processing center) is improved, and the overall resource utilization rate in the service processing process is further improved.

Alternatively, the second data processing center 12 transmits the second service data to the second edge switch 114 of the first data processing center 11 and the sixth edge switch 134 of the data backup center 13 through the fourth edge switch 124 to achieve data synchronization. When detecting that the communication link corresponding to the third edge switch 123 has a fault, the second data processing center 12 sends the second service data to the second edge switch 114 of the first data processing center 11 and the sixth edge switch 134 of the data backup center 13 through the fourth edge switch 124, so as to achieve service data synchronization.
