Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a disaster recovery switching method, apparatus, device, storage medium and computer program product. Background Art

[0002] With the continuous development of Internet information technology, the scale of an enterprise's IT system is also expanding. Whether the IT system can operate normally will directly affect the daily business operations of the enterprise.

[0003] With the deepening of digital development, data centers and big data platforms have gradually become data infrastructure. Whether the data center can operate normally and continuously will directly affect the daily business operations of the enterprise.

[0004] This is especially true for the financial industry, such as banks, insurance companies, and bond companies. Since the daily business operations of these companies are highly dependent on data centers, in this model where business and data centers are closely linked, once a sudden failure occurs in the data center, resulting in the loss of key business data or the inability to restore the information system as soon as possible, it will seriously affect the normal operation of these companies' businesses, causing huge economic losses and adverse social impacts.

[0005] In order to avoid economic losses caused by sudden failures in data centers, existing solutions usually perform disaster recovery backup on data centers. When a primary data center fails, in order to ensure business continuity, it is necessary to quickly switch to a backup data center corresponding to the primary data center, and the backup data center will replace the primary data center to continue providing services.

[0006] In the prior art, when a data center suddenly fails, when performing disaster recovery switching of the data center, the operation and maintenance staff inside the data center need to manually modify the route to point to the disaster recovery data center. After the modification is completed, the old service connection session is interrupted and invalid, and the connection is re-established in the disaster recovery data center.

[0007] Due to the complexity of the system architecture, operation and maintenance personnel need to be very familiar with the system architecture in order to perform rapid switching. During the switching process, operation and maintenance personnel need to perform a series of operations, which consumes a lot of human resources and costs, and greatly reduces the efficiency of disaster recovery switching. During the switching process, the business will be briefly interrupted, affecting business continuity and user experience.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0022] The existing disaster recovery switching relies on manual implementation, and the operation and maintenance staff need to perform a series of operations during the switching process, which consumes a lot of human resources and costs, greatly reduces the efficiency of disaster recovery switching, and during the switching process, the business will be temporarily interrupted, affecting business continuity and user experience. The embodiment of the present application provides a disaster recovery switching method.

[0023] The executor of the disaster recovery switching method provided in the embodiment of the present application may be, but is not limited to, at least one of a disaster recovery management server, a disaster recovery server, or a data center management server; in addition, the executor of the method may also be an application (Application, APP) running on these servers or the system itself.

[0024] For ease of description, the following takes the method being performed by a disaster recovery management system as an example to introduce the implementation of the method. It is understandable that the method being performed by a disaster recovery management system is only an exemplary description and should not be understood as a limitation on the method.

[0025] The specific implementation flow diagram of the disaster recovery switching provided in this application is as follows Figure 1 As shown, it mainly includes the following steps: Step 11, determining whether the line connection of the first data center is interrupted; In an embodiment of the present application, the disaster recovery management system can determine whether the line connection of the first data center is interrupted by configuring heartbeat detection of the switch.

[0026] Specifically, in the pre-configuration phase, the disaster recovery management system can configure the primary line between each operator's network equipment and the primary data center, wherein the network equipment interacts with the primary data center through the primary line, sequentially passing through the boundary port of the security protection device, the non-boundary port of the security protection device, the intrusion prevention device (IPS), and the service message. When the heartbeat detection message sent by the primary line cannot be received according to the preset conditions, it is determined that the primary line between the network device and the primary data center fails, resulting in line interruption.

[0027] In an embodiment of the present application, the disaster recovery management system can implement heartbeat detection based on the Bidirectional Forwarding Detection (BFD) protocol by configuring the BFD protocol on the switch, thereby realizing automatic detection of line connectivity between the primary data center and the network device.

[0028] It should be noted here that in the embodiment of the present application, according to the needs of the actual usage scenario, the disaster recovery management system can configure the heartbeat detection of the switch to sequentially detect the connectivity of the single main line between the main data center and the network equipment, the main line between the main data center and a single operator's network equipment, and the main line between the main data center and all operator network equipment to determine whether the line is interrupted by a fault.

[0029] Step 12, when the line connection is interrupted by executing step 11, determining the optimal routing path through a dynamic routing protocol; In an embodiment of the present application, the disaster recovery management system can configure corresponding dynamic routing protocols on the router, such as Routing Information Protocol (RIP), Open Shortest Path First (OSPF) or Border Gateway Protocol (BGP), etc., which will be responsible for propagating routing information between routers.

[0030] Specifically, routers exchange routing information through dynamic routing protocols. For example, for distance vector routing protocols (such as RIP), routers will periodically broadcast their routing tables to neighboring routers; for link state routing protocols (such as OSPF), routers will broadcast link state information, and then each router uses this information to calculate the best routing path to each network when the main line fails.

[0031] Step 13, obtaining an updated routing table according to the optimal routing path determined by executing step 12, and forwarding the data traffic to the disaster recovery data center according to the updated routing table.

[0032] It should be noted here that, in response to the above three different main line interruption situations, in the embodiment of the present application, the disaster recovery management system can perform line switching respectively according to the following methods: Type 1, single line interruption; When it is determined by executing step 12 that a single line of the first data center is interrupted, after determining the optimal path and updating the routing table of each router according to the optimal path, the disaster recovery management system can determine the interconnection line between the first data center and the disaster recovery data center according to the updated routing table. During this period, the network equipment normally sends business messages to the first data center, and then forwards the business message data to the disaster recovery data center through the interconnection line between the first data center and the disaster recovery data center, thereby achieving disaster recovery switching of the data center while ensuring business continuity.

[0033] Type 2, single operator line outage; When it is determined by executing step 12 that the primary line between the first data center and a single operator is interrupted, after determining the optimal path and updating the routing table of each router according to the optimal path, the disaster recovery management system can enable the backup firewall located in the disaster recovery data center and forward the data traffic to the disaster recovery data center according to the updated routing table. During this period, the network equipment normally sends the service message to the first data center, and then forwards the service message data to the disaster recovery data center through the interconnection line between the first data center and the disaster recovery data center, thereby realizing the disaster recovery switching of the data center while ensuring business continuity.

[0034] Type 3: all operator lines are disconnected; When it is determined by executing step 12 that the main lines between the first data center and all operators are interrupted, after determining the optimal path and updating the routing table of each router according to the optimal path, the disaster recovery management system can enable the backup line access area located in the disaster recovery data center, and forward the data traffic to the disaster recovery data center according to the updated routing table and the backup line access area. During this period, the network equipment normally sends business messages to the first data center, and then forwards the business message data to the disaster recovery data center through the interconnection line between the first data center and the disaster recovery data center, thereby realizing the disaster recovery switching of the data center while ensuring business continuity.

[0035] By adopting the disaster recovery switching method provided in the embodiment of the present application, the disaster recovery system can dynamically determine whether the line connection of the first data center in the current operation is interrupted. When it is determined that the connection is interrupted, the disaster recovery system can determine the optimal routing path through the dynamic routing protocol, and obtain an updated routing table based on the optimal routing path, and forward the data traffic to the disaster recovery data center according to the updated routing table. By adopting the method provided in the embodiment of the present application, after detecting that a data center fails and the connection is interrupted, the disaster recovery system can automatically determine the optimal routing path through the dynamic routing protocol, and then update the routing table according to the optimal routing path, and switch the data center to the disaster recovery data center according to the updated routing table, and forward the data traffic to the disaster recovery data center, so as to accurately and efficiently realize disaster recovery switching while ensuring business continuity.

[0040] In one embodiment, when the connectivity detection unit 21 determines that a single line of the first data center is interrupted through the switch configuration heartbeat detection, the disaster recovery switching unit 23 is specifically used to: determine the interconnection line between the first data center and the disaster recovery data center according to the updated routing table; and forward data to the disaster recovery data center according to the interconnection line.

[0041] In one embodiment, when the connectivity detection unit 21 determines that the line between the first data center and a single operator is interrupted through the switch configuration heartbeat detection, the disaster recovery switching unit 23 is specifically used to: enable a backup firewall located in the disaster recovery data center; obtain an updated routing table according to the optimal routing path, and forward data traffic to the disaster recovery data center according to the updated routing table.

[0042] In one embodiment, when the connectivity detection unit determines through the switch configuration heartbeat detection that the lines between the first data center and all operators are interrupted, the disaster recovery switching unit 23 is specifically used to: enable the backup line access area located in the disaster recovery data center; obtain an updated routing table according to the optimal routing path, and forward the data traffic to the disaster recovery data center according to the updated routing table and the backup line access area.
