Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

At present, object storage services are deployed in a plurality of regions throughout the country, different regions provide different domain names to the outside, the total number of the domain names is as many as several tens, and the number of IP addresses corresponding to each domain name is also more than ten, that is, the number of the integrally related IP addresses is as many as several hundreds, and if only manual maintenance is relied on, the maintenance complexity is extremely high. In addition, the object storage domain name relates to tens of operators, when a certain IP address of the domain name has a fault, if a mode of artificially comprehensively judging an available destination IP address according to operation indexes such as residual bandwidth, packet loss rate, network delay and the like of the IP address and artificially changing the domain name configuration is adopted, more time is consumed, so that the efficiency of switching the IP is low, the error rate is high, errors are easy to occur, further, the efficiency of switching the IP address directly affects the user to access the object storage service, namely, the slower the IP address is switched, the longer the fault duration is, the greater the influence on the object storage service is. Based on this, the embodiment of the invention provides an IP address switching method, an IP address switching device and computer equipment based on object storage, so as to solve the technical problems of low switching efficiency and high error rate in the prior art.

To facilitate understanding of the present embodiment, first, a detailed description is given to an IP address switching method based on object storage disclosed in the present embodiment, referring to a schematic flow chart of the IP address switching method based on object storage shown in fig. 1, where the method mainly includes the following steps S102 to S108:

step S102, a pre-maintained domain name and IP address corresponding relation table and an IP address operation index table are obtained. The domain name and IP address correspondence table may be used to represent a mapping relationship between a domain name and an IP address, one domain name may correspond to a plurality of IP addresses, and the IP address operation index table may be used to represent operation indexes of each IP address, such as one or more of traffic, remaining bandwidth, network delay, and packet loss rate. In one embodiment, when configuring a domain name and an IP address corresponding to the domain name, the corresponding relationship between the domain name and the IP address may be stored in the table of the corresponding relationship between the domain name and the IP address, so as to maintain the table of the corresponding relationship between the domain name and the IP address; in addition, the operation indexes of all the IP addresses can be collected according to a preset period, so that the collected operation indexes are stored in an IP address operation index table, and the maintenance of the IP address operation index table is realized. Optionally, it can be seen that the domain name and IP address correspondence table and the IP address operation index table are stored in the database, so that the domain name and IP address correspondence table and the IP address operation index table are obtained from the database.

And step S104, determining the failed target domain name, and determining the IP address corresponding to the target domain name based on the corresponding relation table of the domain name and the IP address. In one embodiment, since the correspondence between the domain name and the IP address is stored in the domain name and IP address correspondence table, when a failed target domain name is determined, an IP address corresponding to the target domain name may be queried from the domain name and IP address correspondence table, where the IP address corresponding to the target domain name is one or more, for example, when a certain domain name cannot be resolved, the domain name is determined as the failed target domain name, and a plurality of IP addresses corresponding to the target domain name are determined.

And step S106, determining the operation index of the IP address corresponding to the target domain name based on the IP address operation index table. In one embodiment, since the IP address operation index table stores the operation index of each IP address, after the IP address corresponding to the target domain name is determined, the operation index of the IP address corresponding to the target domain name can be searched in the IP address operation index table.

And S108, selecting the optimal IP address to bind with the target domain name based on the operation index of the IP address corresponding to the target domain name. The binding of the optimal IP address and the target domain name may be understood as switching the traffic of the target domain name to the optimal IP address. In an embodiment, assuming that the operation index includes a traffic, a remaining bandwidth, a network delay, and a packet loss rate, the remaining bandwidth of each IP address may be compared with the traffic of the failed IP address, the network delay between each IP address is compared, and the packet loss rate between each IP address is compared, so that the IP address with the remaining bandwidth greater than the traffic of the failed IP address, the network delay being the minimum, and the packet loss rate being the minimum is determined as the optimal IP address, and the optimal IP address is bound with the target domain name, so as to implement the switching of the IP addresses.

The IP address switching method based on object storage provided in the embodiment of the present invention can automatically determine the operation index of the IP address corresponding to the failed target domain name on the basis of the domain name and IP address correspondence table and the IP address operation index table, so that an optimal IP address can be selected for switching based on the operation index of the IP address.

Before obtaining the operation index table of the pre-maintained IP address, an embodiment of the present invention provides an implementation manner of the operation index table of the pre-maintained IP address, which may periodically collect operation indexes of each IP address, and then update the collected operation indexes of each IP address in the operation index table of the IP address. Optionally, an acquisition period may be configured in advance, so that the operation indexes of each IP address are periodically acquired according to the acquisition period, where the operation indexes include at least traffic, residual bandwidth, network delay, and packet loss rate, and then the acquired operation indexes are updated to the IP address operation index table.

In order to facilitate understanding of the IP address operation index table, an IP address with an IP address ID of 1 is taken as an example for description, as shown in table 1 below, where data such as an acquisition time "2020-4-2510: 00: 00", an IP address "1.1.1.1", an IP address traffic "22685231223", a remaining bandwidth "34685443922", a network delay "43", and a packet loss rate "0" are shown in table 1. Wherein the unit of "IP address traffic" is bps; the unit of "network delay" is milliseconds ms; the unit of "packet loss rate" is percentage%, i.e. 5 represents 5%. It should be noted that the data referred to in table 1 are examples, and are not actual data.

TABLE 1

In addition, to facilitate understanding of step S102, an embodiment of the present invention provides a table of correspondence between domain names and IP addresses, referring to a schematic diagram of the table of correspondence between domain names and IP addresses shown in fig. 2, as shown in fig. 2, each region corresponds to a plurality of domain names, the domain names are distributed in different regions, and a user may use an object storage service by accessing the domain names, each domain name corresponds to a plurality of IP addresses, and different IP addresses belong to different network operators. For example, taking a region a and a region B as an example, the region a and the region B respectively represent physical locations of data centers where objects are stored, the region a corresponds to a domain name A1 and a domain name a2, the region B corresponds to a domain name B1 and a domain name B2, the domain name A1 may correspond to a plurality of IP addresses of a telecom, unicom, mobile, or other network operator, such as the domain name A1 may correspond to the IP addresses IP _ A1ct1 and IP _ A1ct2 of the network operator X, and may also correspond to the IP addresses IP _ A1cu1 and IP _ A1cu2 of the network operator Y.

In an embodiment, the domain name and IP address correspondence table includes whether the domain name and IP address correspondence table is a backup identifier, where the domain name and IP address correspondence table may also be used to represent whether each IP address provides a service to the outside, where an IP address that does not provide a service to the outside is also a backup IP address, and optionally, the backup identifier may be marked on the backup IP address to select from the backup IP addresses when determining an IP address corresponding to the target domain name. For example, the backup identifier may adopt a specified value, that is, whether the IP address provides a service to the outside may be represented by the specified value, for example, when the specified value is 1, it indicates that the IP address provides a service to the outside, and when the specified value is 0, it indicates that the IP address does not provide a service to the outside, the IP address is a standby IP address.

In practical application, all domain names and IP addresses stored in the object may be stored in a database in a table form, including a domain name table, an IP address table, and a domain name and IP address correspondence table. Illustratively, the embodiment of the present invention provides a domain name table as shown in table 2, where table 2 indicates that the domain name table may include data such as a domain name ID, a physical location of the domain name, and a domain name, and takes a domain name with a domain name ID of 1 as an example, where the physical location of the domain name is "region a", and the domain name is "a. In addition, an IP address table shown in table 3 is provided in the embodiment of the present invention, where table 3 shows that the IP address table may include data such as an IP address ID, an IP address, and an operator to which the IP address belongs, and the IP address is "1.1.1.1" taking the IP address with the IP address ID of 1 as an example, and the IP address belongs to a beijing telecom operator. In addition, the embodiment of the present invention further provides a table of correspondence between domain names and IP addresses as shown in table 4, where table 4 shows that the table of correspondence between domain names and IP addresses may include a domain name ID, an IP address ID and a designated numerical value, where the domain name ID1 corresponds to the IP address ID1, the IP address ID1 provides external services, the domain name ID1 also corresponds to the IP address 4, and the IP address ID4 does not provide external services (is a spare IP address). Combining tables 2, 3 and 4, it can be concluded that: the IP address corresponding to the a.beijing.domain.com domain name includes "1.1.1.1", "2.2.2.2", "3.3.3.3", "4.4.4.4". Wherein "1.1.1.1", "2.2.2" and "3.3.3.3" provide service to the outside, and "4.4.4.4" is a standby IP address for IP switching.

On the basis of the table of correspondence between domain names and IP addresses provided in the above embodiment, the embodiment of the present invention provides an implementation manner for determining an IP address corresponding to a target domain name based on the table of correspondence between domain names and IP addresses, and all IP addresses having backup identifiers corresponding to the target domain name may be determined based on the table of correspondence between domain names and IP addresses, that is, an IP address corresponding to the target domain name is selected from IP addresses whose assigned numerical value is 0.

For the foregoing step S108, the step of selecting an optimal IP address to bind with the target domain name based on the operation index of the IP address corresponding to the target domain name may be performed according to the following methods shown in steps 1 to 6:

step 1, determining a first IP address of which the residual bandwidth is larger than the flow of the IP address with the fault in the IP address corresponding to the target domain name. In practical application, the remaining bandwidth of each backup IP address corresponding to the target domain name and the traffic of the failed IP address may be compared, so as to select the remaining bandwidth and the first IP address of the traffic of the failed IP address from each backup IP address corresponding to the target domain name.

And 2, if the first IP address comprises one, binding the first IP address with the target domain name. If only a unique first IP address is determined in each standby IP address corresponding to the target domain name, the first IP address is directly bound with the target domain name, and the flow of the IP address with the fault is switched to the first IP address.

And 3, if the first IP addresses comprise a plurality of first IP addresses, determining a second IP address with the minimum packet loss rate in the plurality of first IP addresses. If a plurality of first IP addresses are determined from the standby IP addresses corresponding to the target domain name, packet loss rates of the first IP addresses may be further compared, and the first IP address with the smallest packet loss rate is determined as the second IP address.

And 4, if the first IP address comprises a plurality of IP addresses and the second IP address comprises one IP address, binding the second IP address with the target domain name. And if the unique IP address with the minimum packet loss rate exists in the first IP address, determining the IP address as a second IP address, and binding the second IP address with the target domain name so as to switch the flow of the IP address with the fault to the first IP address.

And step 5, if the second IP address comprises a plurality of second IP addresses, determining a third IP address with the minimum network delay in the plurality of second IP addresses. In practical application, the packet loss rates of a plurality of IP addresses are the same, and if a plurality of second IP addresses are determined from the first IP address, the network delays of the second IP addresses may be further compared, and the second IP address with the smallest network delay is determined as the third IP address.

And 6, binding the third IP address with the target domain name. In an embodiment, the number of the third IP addresses may also be one or more, if the number of the third IP addresses is one, the third IP addresses are directly bound with the target domain name, and if the number of the third IP addresses is more, one third IP address may be arbitrarily selected to be bound with the target domain name.

In order to facilitate understanding of the IP address switching method based on object storage provided in the foregoing embodiment, an application example of the IP address switching method based on object storage is provided in the embodiment of the present invention, referring to a schematic flow chart of another IP address switching method based on object storage shown in fig. 3, the method mainly includes the following steps S302 to S318:

step S302, according to the domain name table, the IP address table and the corresponding relation table of the domain name and the IP address, an IP address list corresponding to the fault domain name is determined. The failed domain name is also the target domain name with the failure, and the IP address list is also all the IP addresses corresponding to the target domain name.

Step S304, a first IP address list is determined according to the IP address operation index table. The first IP address list comprises a first IP address of which the residual bandwidth in the IP addresses corresponding to the target domain name is larger than the flow of the IP address with the fault.

And step S306, determining a second IP address from the first IP address list according to the IP address operation index table. In an embodiment, the first IP address with the smallest packet loss rate may be selected from the first IP address list as the second IP address according to the packet loss rate recorded in the IP address operation index table.

Step S308, determine whether the number of the second IP addresses is multiple. If yes, go to step S312; if not, step S310 is performed.

Step S310, the flow of the IP address with the fault is switched to a second IP address.

Step S312, determine a third IP address from the second IP address according to the IP address operation table. In the payload implementation, the second IP address with the smallest network delay may be selected from the plurality of second IP addresses as the third IP address according to the network delay recorded in the IP address operation index table.

Step S314 determines whether the number of the third IP addresses is plural. If yes, go to step S318; if not, step S316 is performed.

And step S316, switching the flow of the IP address with the fault to a third IP address.

Step S318, selecting any third IP address, and switching the traffic of the failed IP address to the selected third IP address.
