Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

The bandwidth management method provided by the embodiment of the application can be applied to an application environment shown in figure 1. As shown in fig. 1 and 2, the application environment includes a disaster recovery platform 10, a request end 20, and a backup end 30. The disaster recovery platform 10 is connected to the request end 20 and the backup end 30 through a network. The disaster recovery platform 10 is configured to determine a target backup link corresponding to the data backup request in response to the data backup request sent by the request end 20, send a query request to the backup end 30, obtain target configuration information of the target backup link and a query response sent by the backup end 30 according to the query request, and manage a target bandwidth service of the target backup link according to the target configuration information and the query response. The production node 21 may be understood as a node that generates source data to be backed up, for example, data generated by the production database 211, middleware, etc. in the production node 21 needs to be backed up. For example, the production node 21 may be a local machine room, private cloud, or other pool of resources where there is a need for data backup, etc. The request end 20 may be understood as a terminal or a server corresponding to the production node 21, where the request end 20 is configured to manage the production node 21. The backup node 31 is configured to backup source data, for example, the backup node 31 may be a cloud computer room, a private cloud, or other resource pool capable of backing up data, etc. The backup terminal 30 may be understood as a terminal, a server, or a platform corresponding to the backup node 31, where the backup terminal 30 is configured to manage the backup node 31.

It can be understood that the target backup link is used to transmit the data generated by the production node 21 of the request end 20 to the backup node 31 of the backup end 30 via the cloud dedicated line for backup. For example, as shown in fig. 2, taking a scenario in which data generated by the production database 211 of the production node 21 needs to be backed up to the backup database 313 of the backup node 31 as an example, the target backup link refers to a scenario from the production database 211 of the production node 21 to the local gateway 213 via the data synchronization tool 212, then to the dedicated line gateway 311 of the backup node 31 via the cloud dedicated line, and then to the backup database 313 via the cloud gateway 312.

Cloud private line is a connection service between a user's local data center and a VPC (Virtual Private Cloud ). The cloud private line product flexibly builds a dedicated connection channel with high speed, low time delay, stability and safety under the cloud by depending on the existing IT (Information Technology ) infrastructure. One end of the private line is connected with the local gateway 213 equipment, and the other end is connected with the private line gateway 311, so that the internal local area network of the user local data center is connected to the access point of the backup cloud end, and the internal network-level communication quality is realized. In the embodiment of the present application, the cloud private line may be understood as a private line gateway 311 for connecting the local gateway 213 of the production node 21 and the backup node 31.

In one embodiment, as shown in fig. 1 to 3, a bandwidth management method is provided, and the method is applied to the disaster recovery platform in fig. 1 for illustration, and includes the following steps S302 to S306.

S302, responding to a data backup request sent by a request end, determining a target backup link corresponding to the data backup request, and sending a query request to the backup end.

The data backup request is used to represent a request to backup data generated by a production node at the requesting end. Illustratively, the data backup request includes data source subnet information, backup subnet information, and target bandwidth limit information. The data source subnet information is used for representing subnet segment information of the production node, and can be represented by CIDR (CLASSLESS INTER-Domain Routing, class-free inter-Domain Routing) format. The backup subnet information is used to represent subnet segment information of the backup node, and may also be represented in CIDR format. The target bandwidth speed limit information is used for representing information related to bandwidth speed limit of the target backup link. Illustratively, the target bandwidth speed limit information includes a bandwidth speed limit value and a bandwidth packet ID (Identity). The bandwidth speed limit value can be the maximum transmission speed of a target backup link set by a user, wherein the unit is MB/s, the bandwidth packet identifier is used for identifying a bandwidth packet, and the bandwidth packet is the bandwidth packet acted by a special cloud line bandwidth speed limit product purchased by the user.

In the application, after receiving the data backup request, the disaster recovery platform can judge whether the bandwidth limit value in the data backup request is larger than the maximum value of the cloud private line bandwidth corresponding to the bandwidth packet ID according to the bandwidth packet ID, if so, the bandwidth limit value set by the user is adjusted, and the adjusted bandwidth limit value is smaller than or equal to the maximum value of the cloud private line bandwidth corresponding to the bandwidth packet ID.

The query request is used for querying the bandwidth service of the backup terminal to the cloud private line in the backup link. The query request is intended to query the bandwidth service created in the backup side. The bandwidth service is a service for managing and controlling the bandwidth of a cloud dedicated line of a backup link for data transmission between a production node and a backup node. The target backup link is used for transmitting the data generated by the production node of the request end to the backup node of the backup end for backup through the cloud private line. The bandwidth service created by the backup end may or may not include the target bandwidth service of the target backup link.

In the application, after receiving the data backup request sent by the request end for the first time, the disaster recovery platform can instruct the backup end to open the backup database at the backup node and instruct the request end to deploy the data synchronization tool at the production node, thereby determining the target backup link corresponding to the data backup request, that is, the target backup link is sequentially connected to the cloud private line from the production database of the production node through the data synchronization tool and the local gateway, and then sequentially connected to the backup database through the private line gateway and the cloud gateway of the backup node. And after receiving the data backup request, the disaster recovery platform can call an API (Application Program Interface ) to send a query request to the backup terminal so as to query whether the bandwidth service corresponding to the created cloud private line exists.

S304, acquiring target configuration information of a target backup link and query response sent by the backup terminal according to the query request.

The target configuration information is used to represent information related to the target backup link configuration. Illustratively, the target configuration information includes target tuple information and target bandwidth limit information. Wherein the target tuple information is used to identify a base element of the target backup link in the network communication. Illustratively, the destination tuple information includes source IP (Internet Protocol ) address information, source port information, destination IP address information, destination port information, and transport protocol information of the destination backup link. Wherein the source IP address, source port, destination IP address, destination port, and transport protocol are collectively referred to as a five-tuple. The target bandwidth speed limit information is used for indicating information for limiting the speed of the cloud private line bandwidth in the target backup link. Illustratively, the target bandwidth limit information includes a bandwidth limit value and a bandwidth packet ID.

The query response is generated and sent by the backup terminal according to the query request. The query response is used for indicating whether the backup terminal has the query result of the bandwidth service corresponding to the created cloud private line. In an exemplary case that the backup end has the created cloud private line bandwidth service, the query response includes history attribute information of the bandwidth service corresponding to the created cloud private line, or simply referred to as a history bandwidth service object, where the history attribute information is used to represent information related to the history bandwidth service. Still further exemplary, in the case that the backup end does not have the bandwidth service corresponding to the created cloud private line, the query response does not include the historical bandwidth service object.

And S306, managing the target bandwidth service of the target backup link according to the target configuration information and the query response.

The target bandwidth service is used for carrying out speed limiting management on the cloud private line bandwidth of the target backup link. The target bandwidth service is configured to perform speed limiting management on the cloud private line bandwidth of the target backup link according to the bandwidth speed limiting value, where the bandwidth speed limiting value can be described in the foregoing, and is not described herein. In the embodiment of the application, the bandwidth service can be understood as a service for limiting the speed of the special cloud bandwidth of the backup link in the backup service.

In the application, the disaster recovery platform can manage the target bandwidth service according to the target configuration information and the query response. The target bandwidth service is managed, which may be understood as instructing the backup end to create the target bandwidth service, update the target bandwidth service, delete the target bandwidth service, and so on, which will be described in detail below.

The backup terminal can provide the target bandwidth service for the request terminal, so that source data generated by the production node such as a production database is backed up to a backup database of the backup node under the bandwidth speed limit condition of the target bandwidth service, and thus, the data disaster recovery backup is realized.

According to the bandwidth management method, the target backup link corresponding to the data backup request is determined in response to the data backup request sent by the request end, the query request is sent to the backup end, the target configuration information of the target backup link and the query response sent by the backup end according to the query request are obtained, and the target bandwidth service of the target backup link is managed according to the target configuration information and the query response, so that the bandwidth of the target backup link can be limited based on the target bandwidth service, the bandwidth limitation of the data backup link is realized, the influence on other network services sharing a cloud private line with the data backup service is avoided, and the stability and the reliability of network transmission are ensured. Compared with the control of the data transmission speed by using the data synchronization tool (for example, setting the parallel synchronous process number, the single batch transmission number and the like), the embodiment of the application realizes the transmission speed limitation from the network layer instead of the application layer, can control the bandwidth used by the data synchronization more accurately, and expands the control range of the data bandwidth. In addition, the bandwidth management method provided by the embodiment of the application can automatically adjust and manage the corresponding target bandwidth service based on the data backup requests sent by the request terminals, thereby realizing the self-adaptive management of different data backup links corresponding to the data backup requests sent by different request terminals, and improving the effective management and control of the bandwidth service.

In one embodiment, as shown in fig. 4, step S306 manages the target bandwidth service of the target backup link according to the target configuration information and the query response, including the following steps S402 to S406.

And S402, under the condition that the number of the historical bandwidth services included in the query response is 0, sending a creation instruction to the backup terminal to instruct the backup terminal to create the target bandwidth service and obtain target bandwidth identification information of the target bandwidth service sent by the backup terminal, wherein the creation instruction comprises target configuration information.

If the number of the historical bandwidth services included in the query response is 0, the fact that the backup end does not have the bandwidth services corresponding to the created cloud private line is indicated, and in this case, the disaster recovery platform instructs the backup end to create the target bandwidth services corresponding to the target backup link according to the creation instruction by sending the creation instruction to the backup end.

The creation instruction includes target configuration information. Illustratively, the target configuration information includes target tuple information and target bandwidth speed limit information, wherein the target tuple information includes source IP address information, source port information, destination IP address information, destination port information, and transport protocol information of the target backup link, and the target bandwidth speed limit information includes a bandwidth speed limit value and a bandwidth packet ID. The target configuration information can be seen as shown in table 1 below.

TABLE 1

Where String represents a String type and intelger represents an Integer type. For example, the transport protocol information may include TCP (Transmission Control Protocol, transport control protocol).

In the application, after receiving the creation instruction, the backup terminal creates a target backup link and a target bandwidth service of the target backup link according to target configuration information in the creation instruction, and sends target bandwidth identification information of the target bandwidth service to the disaster recovery platform, so that the disaster recovery platform can manage and control the target bandwidth service according to the target bandwidth identification information. Wherein the target bandwidth identification information is used to identify the target bandwidth service.

And S404, acquiring target bandwidth identification information of the target backup link according to the target configuration information and the history attribute information of each history bandwidth service under the condition that the query response comprises at least one history bandwidth service.

If the query response includes at least one historical bandwidth service, it indicates that the backup end has the bandwidth service corresponding to the created cloud private line, that is, the historical bandwidth service, in this case, the disaster recovery platform may obtain, according to the target configuration information and the historical attribute information of each historical bandwidth service, the target bandwidth identification information of the target backup link, so as to manage the target bandwidth service according to the target bandwidth identification information.

The history attribute information is used to represent information related to the history bandwidth service. The history attribute information includes history configuration information and history bandwidth identification information, where the history configuration information is used to represent information related to the configuration of the history bandwidth service, and similar to the target configuration information of the target bandwidth service, reference may be made to the description of the target configuration information above, and details thereof are not repeated herein. The historical bandwidth identification information is used to identify historical bandwidth services.

And S406, managing the target bandwidth service according to the target bandwidth identification information.

In the application, the disaster recovery platform can manage the target bandwidth service provided by the backup terminal for the request terminal according to the target bandwidth identification information.

In the bandwidth management method, when the number of the historical bandwidth services included in the query response is 0, a creation instruction is sent to the backup terminal to instruct the backup terminal to create the target bandwidth services, target bandwidth identification information of the target bandwidth services sent by the backup terminal is obtained, and when the query response includes at least one historical bandwidth service, the target bandwidth identification information of the target backup link is obtained according to the target configuration information and the historical attribute information of each historical bandwidth service, and the target bandwidth services are managed according to the target bandwidth identification information.

In one embodiment, as shown in fig. 5, the target configuration information includes target tuple information, and the history attribute information includes history tuple information, where step S404 obtains target bandwidth identification information of the target backup link according to the target configuration information and the history attribute information of each history bandwidth service, including the following steps S502 and S504.

And S502, sending a creation instruction to the backup terminal to instruct the backup terminal to create the target bandwidth service under the condition that the target tuple information and the history tuple information are different, wherein the creation instruction comprises target configuration information.

S504, obtaining target bandwidth identification information sent by the backup terminal.

Illustratively, in the case that the query response includes at least one historical bandwidth service, the disaster recovery platform compares the target tuple information of the target backup link with the historical tuple information of each historical bandwidth service, and obtains a comparison result. The comparison result is used to indicate whether the target tuple information is identical to each history tuple information. Taking the tuple information including quintuple information, namely source IP address information, source port information, destination IP address information, destination port information and transmission protocol information as examples, the disaster recovery platform compares the target quintuple information with the history quintuple information one by one, and determines that the target quintuple information is different from the history quintuple information when at least one of the target quintuple information and the history quintuple information is different.

If the comparison result shows that the target tuple information is different from each history tuple information, the backup end does not have the history bandwidth service aiming at the target backup link, in this case, the disaster recovery platform sends a creation instruction to the backup end, so as to instruct the backup end to create the target backup link and the target bandwidth service of the target backup link according to the target configuration information in the creation instruction, and send target bandwidth identification information corresponding to the target bandwidth service to the disaster recovery platform, so that the disaster recovery platform manages the target bandwidth service according to the target bandwidth identification information.

According to the bandwidth management method, under the condition that the target tuple information and the historical tuple information are different, the creation instruction is sent to the backup terminal to instruct the backup terminal to create the target bandwidth service and acquire the target bandwidth identification information sent by the backup terminal, and under the condition that the historical bandwidth service meeting the data backup request does not exist, the new target bandwidth service is created, so that the backup service is provided, meanwhile, the speed limit can be carried out on the bandwidth of the cloud private line in the target backup link through the target bandwidth service, the influence of the backup service on the network transmission quality of other network services is reduced, and the reliability of the whole service of the system is improved.

In one embodiment, as shown in fig. 6, the target configuration information includes target tuple information and target bandwidth speed limit information, the history attribute information includes history configuration information and history bandwidth identification information, the history configuration information includes history tuple information and history bandwidth speed limit information, and step S404 includes the following steps S602 and S604, where the target bandwidth identification information of the target backup link is obtained according to the target configuration information and the history attribute information of each history bandwidth service.

And S602, determining candidate bandwidth services from the historical bandwidth services according to the target tuple information and the historical tuple information, wherein the historical tuple information of the candidate bandwidth services is identical to the target tuple information.

And S604, determining historical bandwidth identification information of the candidate bandwidth service as target bandwidth identification information.

If the comparison result is that the target tuple information is the same as the historical tuple information of at least one historical bandwidth service, the backup end has at least one historical bandwidth service (called as standby bandwidth service for short) aiming at the target backup link, in this case, a candidate bandwidth service is determined from at least one standby bandwidth service, and the historical bandwidth identification information of the candidate bandwidth service is determined as target bandwidth identification information.

The method for determining the candidate bandwidth service from at least one candidate bandwidth service includes the steps of comparing the candidate bandwidth service with target bandwidth speed limit information respectively, determining the candidate bandwidth service as the candidate bandwidth service if the candidate bandwidth service which is the same as the target bandwidth speed limit information exists, determining any one of the candidate bandwidth service as the candidate bandwidth service if the candidate bandwidth service which is the same as the target bandwidth speed limit information does not exist, determining historical bandwidth identification information of the candidate bandwidth service as the target bandwidth identification information by a disaster tolerant platform under the condition, and sending an update bandwidth instruction to a backup end to instruct the backup end to update the historical bandwidth speed limit information of the candidate bandwidth service as the target bandwidth speed limit information according to the update bandwidth instruction, wherein the update bandwidth instruction comprises the historical bandwidth identification information of the candidate bandwidth service and the target bandwidth speed limit information, and the embodiment can be seen in the following table 2.

TABLE 2

In the application, the backup terminal can call the API to update the historical bandwidth speed limit information of the candidate bandwidth service to the target bandwidth speed limit information according to the updated bandwidth instruction.

The bandwidth management method determines a candidate bandwidth service from among the history bandwidth services based on the target tuple information and the history tuple information, determines history bandwidth identification information of the candidate bandwidth service as the target bandwidth identification information, multiplexes the history bandwidth service of the candidate bandwidth service in the case that there is the same candidate bandwidth service as the target tuple information, the method can avoid creating excessive bandwidth service, reduce resource consumption, limit the speed of the bandwidth of the cloud private line in the target backup link through the multiplexed historical bandwidth service while providing backup service, reduce the influence of the backup service on the network transmission quality of other network services, and improve the reliability of the whole service of the system.
