Detailed Description

Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.

The method, apparatus, electronic device, and storage medium for limiting virtual machine traffic according to the embodiments of the present disclosure are described below with reference to the accompanying drawings.

The embodiment of the present disclosure is exemplified by the method that the virtual machine flow rate limiting method is configured in a virtual machine flow rate limiting device, and the virtual machine flow rate limiting device may be applied to any electronic device, so that the electronic device may execute a virtual machine flow rate limiting function.

Fig. 1 is a schematic flowchart of a method for limiting a virtual machine traffic rate according to an embodiment of the present disclosure.

As shown in fig. 1, the method for limiting the virtual machine traffic rate may include the following steps:

step 101, receiving a virtual machine speed limit strategy updating request sent by a client, wherein the speed limit strategy updating request comprises a first virtual machine identifier and first speed limit information.

Generally, the speed limit of the traffic passing through a single virtual network card can be realized based on a speed limit strategy of the granularity of the virtual network card, that is, the speed limit is set on the virtual network card. If the speed limit of the flow flowing through the virtual machine is to be realized, all the virtual network cards under the virtual machine need to be configured with corresponding speed limit strategies, so that the complexity of flow speed limit of the virtual machine is increased.

Therefore, in the embodiment of the present disclosure, if the speed limit of the virtual machine needs to be updated, the speed limit policy of the virtual machine may be adjusted according to the received virtual machine speed limit policy update request.

The style or presentation form of the first virtual machine identifier may be set in advance, for example, may be a virtual machine(s) ((c))virtualmachine,vm) A, vm1, etc., as the present disclosure is not limited thereto.

Optionally, the first speed limit information may include at least one of: the speed limit type and a threshold value corresponding to each speed limit type.

The rate-limiting type may be various, such as a broadcast/multicast rate, a number of packets per second (pps) to be sent, that is, a packet sending rate, and a number of bits per second (bps), where the bps may be referred to as a total traffic.

In addition, bps can be further subdivided, such as: network Address Translation (NAT), Load Balance (LB), Elastic Internet Protocol (EIP), and other routing types. The present disclosure is not limited thereto.

In addition, the threshold corresponding to each speed limit type can be a numerical value set in advance; the speed limit types are different, and the threshold values corresponding to the speed limit types may be the same or may also be different, which is not limited in this disclosure.

For example, by analyzing the received update request of the speed limit policy of the virtual machine, if it is determined that the update request includes "virtual machine 1 and packet sending speed", it may be determined that the first virtual machine identifier is "virtual machine 1" and the first speed limit information is: the "speed of contracting" is limited.

Or, by analyzing the received virtual machine speed limit policy update request, if it is determined that the update request includes "virtual machine 2, m", it may be determined that the first virtual machine identifier is "virtual machine 2" and the first speed limit information is: the flow rate is less than or equal to m.

Or, by analyzing the received virtual machine speed limit policy update request, if it is determined that the update request includes "virtual machine 1, NAT, a", it may be determined that the first virtual machine identifier is "virtual machine 1", and in the first speed limit information: the speed limit type is NAT, and the corresponding flow rate threshold value is a.

It should be noted that the above example is only an illustrative example, and cannot be taken as a limitation on the first virtual machine identifier, the first speed limit information, and the like in the implementation of the present disclosure.

Step 102, determining an identifier of a first virtual network card associated with the identifier of the first virtual machine.

The number of the first virtual network card associated with the first virtual machine identifier may be one, or may also be multiple, which is not limited in this disclosure.

It is to be understood that the first virtual network card associated with the first virtual machine identifier may be set in advance, or may also be set by default, and the like, which is not limited in this disclosure.

In addition, the style or presentation form of the identifier of the first virtual network card may be set in advance, and may be, for example: 1. virtual network card 1, virtual network card 02, etc., which are not limited in this disclosure.

Optionally, each first virtual machine identifier and the identifier of the corresponding first virtual network card may be stored in an associated manner in advance, for example, may be stored in a database, so that after the first virtual machine identifier is determined, traversal may be performed in the database to determine the identifier of the first virtual network card associated with the first virtual machine identifier.

For example, if the first virtual machine identifier is "1", the identifiers of the first virtual network card associated with "1" are determined to be "00", "01", "02", respectively, by looking up in the database. Or the first virtual machine is marked as '1', and the mark of the first virtual network card which is associated with '1' is determined as 'a' by searching in the database. The present disclosure is not limited thereto.

Step 103, sending a virtual network card speed limit configuration instruction to the private network gateway on the cloud, wherein the speed limit configuration instruction includes an identifier of the first virtual network card and first speed limit information.

Wherein, a private network (VPC) on the cloud can be a customizable logical isolated network space on the public cloud; a VPC gateway (VPC gateway, vgw), which may implement network interconnection above the network layer, etc., and is not limited in this disclosure.

For example, if the speed limit policy update request of the virtual machine is analyzed, the identifier of the first virtual machine included in the speed limit policy update request is determined to be "1", and the first speed limit information is "LB, d", and then the identifier of the first virtual network card associated with the first virtual machine identifier is determined to be "01", "02" by searching for the first virtual machine identifier "1". And then, a virtual network card speed limit configuration instruction can be sent to vgw, wherein the instruction can include "01, 02, LB, d", so that vgw can set the threshold of LB in the "01" or "02" of the virtual network card to d according to the received virtual network card speed limit configuration instruction, thereby realizing the virtual machine flow speed limit.

It should be noted that the above example is only an illustrative example, and cannot be taken as a limitation on the first virtual machine identifier, the first speed limit information, the first virtual network card identifier, and the like in the embodiment of the present disclosure.

According to the embodiment of the disclosure, a virtual machine speed limit policy update request sent by a client may be received first, where the speed limit policy update request includes a first virtual machine identifier and first speed limit information, then an identifier of a first virtual network card associated with the first virtual machine identifier is determined, and then a virtual network card speed limit configuration instruction may be sent to the private network VPC gateway vgw on the cloud, where the speed limit configuration instruction includes the identifier of the first virtual network card and the first speed limit information. Therefore, the virtual machines are associated with the corresponding virtual network cards, when the flow rate limit requirements of the virtual machines exist, the virtual machines are taken as units, and the multiple virtual network cards associated with the virtual machines can be subjected to rate limit adjustment, so that the complexity of flow rate limit of the virtual machines is reduced, and the flow rate limit process of the virtual machines is simplified.

Fig. 2 is a flowchart illustrating a method for limiting a virtual machine traffic rate according to an embodiment of the present disclosure. As shown in fig. 2, the method for limiting the virtual machine traffic rate may include the following steps:

step 201, receiving a virtual machine speed limit policy update request sent by a client, wherein the speed limit policy update request includes a first virtual machine identifier and first speed limit information.

It should be noted that specific contents and implementation manners of the first speed limit information may refer to descriptions of other embodiments of the disclosure, and are not described herein again.

Step 202, the first virtual machine identifier and the first speed limit information are stored in a database in a correlated mode.

It can be understood that after the received virtual machine speed limit policy update request is analyzed to determine the first virtual machine identifier and the first speed limit information included therein, the first virtual machine identifier and the first speed limit information may be stored in the database in an associated manner.

For example, if it is determined that the first virtual machine identifier is "1" and the first speed limit information is "LB, d", the "first virtual machine 1" and the "subdivision type LB, speed limit threshold value d" may be stored in the database in association. The present disclosure is not limited thereto.

Optionally, after determining the first virtual machine identifier and the first speed limit information according to the virtual machine speed limit policy update request, the first virtual machine identifier and the first speed limit information may be stored in the database. For the same virtual machine, multiple virtual machine speed limit strategy updating requests may be received, and the first virtual machine identifier and the first speed limit information in the database may be updated and stored in a correlated manner according to the time when the strategy updating requests are received. The present disclosure is not limited thereto.

Step 203, traversing a preset association relation table of the virtual machine identifier and the virtual network card identifier to determine the identifier of the first virtual network card associated with the first virtual machine identifier.

The association relationship table may be a table or a chart set in advance and storing the association relationship between the virtual machine identifier and the virtual network card identifier, which is not limited in this disclosure.

For example, if the first virtual machine identifier is "2", the identifiers of the virtual network cards associated with "2" are determined to be "00" and "01" respectively by traversing the preset association relationship table of the virtual machine identifier and the virtual network card identifier, and then the identifiers of the first virtual network cards corresponding to the first virtual machine identifier "2" can be determined to be "00" and "01" respectively. The present disclosure is not limited thereto.

It should be noted that, step 202 may be executed first, and then step 203 is executed, or step 203 may be executed first, and then step 202 is executed, or step 202 and step 203 may also be executed at the same time, and the disclosure is not limited thereto.

Step 204, sending a virtual network card speed limit configuration instruction to the VPC gateway vgw, where the speed limit configuration instruction includes an identifier of the first virtual network card and first speed limit information.

It can be understood that, if there is one first virtual network card corresponding to the first virtual machine identifier, the flow rate limit may be performed on the first virtual network card through the virtual network card rate limit configuration instruction. If the number of the first virtual network cards corresponding to the first virtual machine identifier is multiple, the flow rate of the multiple first virtual network cards related to the first virtual machine identifier can be limited through one virtual network card speed limit configuration instruction. The present disclosure is not limited thereto.

The method for limiting the virtual machine flow rate can be applied to any virtual machine flow rate limiting scene, and the method is not limited by the disclosure.

The following describes a virtual machine traffic speed-limiting process provided by the present disclosure with reference to a schematic diagram of the virtual machine traffic speed-limiting process shown in fig. 2A.

As shown in fig. 2A, when there is a virtual machine traffic speed limit requirement, the client may send a virtual machine speed limit policy update request to the server, where the update request may include a first virtual machine identifier and first speed limit information. After receiving the virtual machine speed limit strategy updating request, the server can store the first virtual machine identifier and the speed limit record corresponding to the first speed limit information into a database, and then can check whether the speed limit record is successfully stored.

In addition, the server side can traverse the database to determine the identifier of the first virtual network card associated with the identifier of the first virtual machine; and sending a virtual network card speed limit configuration instruction to vgw, so that vgw can receive the identifier of the first virtual network card to be updated and the first speed limit information. In addition, the server side can also return a successful message of creating the flow rate limit of the virtual machine to the client side.

It should be noted that the above example is only an illustrative example, and cannot be taken as a limitation on the virtual machine traffic speed limiting process in the embodiment of the present disclosure.

It can be understood that the virtual machine traffic speed limit provided by the present disclosure may be implemented based on three levels of vpc-vm-virtual network cards, and the three-level speed limit diagram may be as shown in fig. 2B. If the first virtual machine identifier is "vm 1" and the associated first virtual network card identifiers are "03, 06", the flow rate limit can be performed on the "03" and "06" virtual network cards associated with the first virtual machine. The present disclosure is not limited thereto.

It can be understood that, if any one first virtual machine is associated with a plurality of first virtual network cards, according to the method for limiting the flow rate of the virtual machine provided by the present disclosure, the flow rate of all the virtual network cards in the virtual machine can be limited by the overall rate-limiting strategy of the virtual machine layer.

For example, by parsing the received virtual machine speed limit policy update request, it is determined that the first virtual machine identifier included therein is "1", the speed limit policy is "packetization rate", and the corresponding threshold value is "m", if the virtual network card associated with the first virtual machine is "01" or "04", respectively, the actual packetization rate m1 of "01" should be less than or equal to "m", and the actual packetization rate m2 of "04" should be less than or equal to "m", and (m 1+ m 2) is less than or equal to m.

Or, as shown in fig. 2C, under the condition of single virtual machine and multiple network cards traffic speed limit, the speed limit type corresponding to the virtual machine may be packet sending speed, broadcast/multicast, total traffic, wherein the total traffic may be further subdivided into: NAT, LB, EIP and other types, and various speed limit types can have corresponding speed limit threshold values. The virtual machine may have a plurality of virtual network cards, for example: a virtual network card 1, a virtual network card 2, a virtual network card 3, a virtual network card n, etc.

It should be noted that the above examples are merely illustrative, and should not be taken as limitations on the manner of limiting the traffic of the virtual machine in the embodiments of the present disclosure.

According to the embodiment of the disclosure, a virtual machine speed limit policy update request sent by a client may be received first, where the speed limit policy update request includes a first virtual machine identifier and first speed limit information, then the first virtual machine identifier and the first speed limit information may be stored in a database in an associated manner, and a preset association relation table of the virtual machine identifier and a virtual network card identifier is traversed to determine an identifier of a first virtual network card associated with the first virtual machine identifier, and then a virtual network card speed limit configuration instruction may be sent to a private proprietary network gateway on the cloud, where the speed limit configuration instruction includes the identifier of the first virtual network card and the first speed limit information. Therefore, the virtual machines are associated with the corresponding virtual network cards, when the flow rate limit requirements of the virtual machines exist, the virtual machines are taken as units, and the multiple virtual network cards associated with the virtual machines can be subjected to rate limit adjustment, so that the complexity of flow rate limit of the virtual machines is reduced, and the flow rate limit process of the virtual machines is simplified. Fig. 3 is a flowchart illustrating a method for limiting a virtual machine traffic rate according to an embodiment of the present disclosure.

As shown in fig. 3, the method for limiting the virtual machine traffic rate may include the following steps:

step 301, receiving a virtual network card update request, where the virtual network card update request includes a second virtual machine identifier and a second virtual network card identifier.

The identifier or the presentation form of the identifier of the second virtual machine may be set in advance, for example, "virtual machine a", "vm 1", and the like, which is not limited in this disclosure.

In addition, the identifier or the presentation form of the identifier of the second virtual network card may be set in advance, for example, "virtual network card 01", "virtual network card 3", and the like, which is not limited in this disclosure.

It can be understood that, when the virtual network card associated with the virtual machine changes, the client may send a virtual network card update request to the server, so that the server may determine the virtual machine identifier and the virtual network card identifier to be updated according to the received virtual network card update request.

Step 302, updating the preset association relation table of the virtual machine identifier and the virtual network card identifier based on the second virtual machine identifier and the second virtual network card identifier.

When the virtual machine identifier and the virtual network card identifier are updated, there may be a plurality of situations, for example, the virtual machine identifier and the virtual network card identifier may be unbound or deleted, or may be newly added, and the like.

For example, by analyzing the virtual network card update request, it is determined that the second virtual machine identifier is "virtual machine 3", and the second virtual network card "0" is unbundled, if the preset association table of the virtual machine identifier and the virtual network card identifier indicates that the second virtual network card identifier associated with the "virtual machine 3" is "0", "1", and "2", respectively, and then the second virtual network card "0" associated with the "virtual machine 3" may be deleted, and then the second virtual network card identifier associated with the "virtual machine 3" in the updated association table may be "0" and "1".

Or, the second virtual machine identifier is determined to be the "virtual machine 3" and the "3" of the second virtual network card is added through analyzing the virtual network card updating request. If the second virtual network card identifiers associated with the "virtual machine 3" in the preset association relationship table of the virtual machine identifiers and the virtual network card identifiers are "1" and "2", respectively, the second virtual network card "3" may be added to the association relationship table, and the second virtual network card identifiers associated with the second virtual machine identifier "virtual machine 3" in the updated association relationship table are "1", "2", and "3", respectively.

Alternatively, as shown in the schematic diagram of the virtual network card associated with the virtual machine in fig. 3A, for the "virtual machine 3", the "network card 0" may be deleted or unbundled, and the "network card 3" may be added or bound, as can be seen from fig. 3A, after the virtual machine "3" performs the unbundling and adding operations, the associated second virtual network card identifiers are "1", "2" and "3", respectively.

It should be noted that, the above example is only an illustrative example, and cannot be used as a limitation on the virtual network card update request and the manner of updating the preset association table in the embodiment of the present disclosure.

Step 303, sending a virtual network card unbinding instruction to vgw when the virtual network card updating request is a virtual network card unbinding request, wherein the unbinding instruction includes a second virtual machine identifier and a second virtual network card identifier.

It can be understood that, if the virtual network card update request is a virtual network card unbinding request, the second virtual network card of the second virtual machine identifier may be unbound in the preset association table of the virtual machine identifier and the virtual network card identifier based on the second virtual machine identifier and the second virtual network card identifier, and then a virtual network card unbinding instruction may be sent to vgw, so that vgw may perform an unbinding operation on the second virtual network card associated with the second virtual machine.

And step 304, acquiring second speed limiting information corresponding to the second virtual machine identifier under the condition that the virtual network card updating request is a virtual network card newly-increased request.

Optionally, the second speed limit information may include at least one of: the speed limit type and the threshold corresponding to each speed limit type are not limited in the disclosure.

The new virtual machine identifier and the corresponding second speed limit information included in the new request can be obtained by analyzing the new request of the virtual network card. The present disclosure is not limited thereto. Or, the second speed limit information corresponding to the second virtual machine identifier may also be acquired by searching in the database.

For example, the second virtual machine identifier is "virtual machine 3", the information associated with "virtual machine 3" is searched in a database storing the virtual machine identifier and the speed limit information in a traversing manner, and if it is determined that the speed limit information corresponding to "virtual machine 3" is: and m is selected. Then it may be determined that the second speed limit information corresponding to "virtual machine 3" is: the velocity is less than or equal to m. The present disclosure is not limited thereto. Or, by analyzing the virtual network card newly-added request, if it is determined that the newly-added request includes "virtual machine 1, packet sending speed", it may be determined that the second virtual machine identifier is "virtual machine 1" and the corresponding second speed limit information is: the "speed of sending a packet" is limited.

Or, by analyzing the virtual network card newly-added request, if it is determined that the newly-added request includes "virtual machine 1, NAT, d", it may be determined that the second virtual machine identifier is "virtual machine 1" and the corresponding second speed limit information: the speed limit type is NAT, and the corresponding threshold value is d.

It should be noted that the above example is only an illustrative example, and cannot be taken as a limitation on the second virtual machine identifier, the second speed limit information, and the like in the implementation of the present disclosure.

And 305, sending a virtual network card speed limit configuration instruction to vgw, wherein the speed limit configuration instruction includes a second virtual network card identifier and second speed limit information.

For example, if the new request for the virtual network card is analyzed to determine that the new request includes "vm 1" and "virtual network card 01", it may be determined that the second virtual machine identifier is "vm 1" and the second virtual network card identifier is "virtual network card 01". If the corresponding second speed limit information is determined to be: a threshold value d. A virtual network card speed limit configuration instruction containing "virtual network card 01 and threshold d" may be sent to vgw, so that vgw may know the identifier of the second virtual network card and the second speed limit information.

It should be noted that the above example is only an illustrative example, and cannot be used as a limitation on the second virtual network card identifier, the second speed limit information, and the like in the embodiment of the present disclosure.

The following describes a flow rate limiting process of the virtual machine provided by the present disclosure, taking a virtual network card update request as an add-on request as an example.

Fig. 3B is a schematic diagram of a flow rate limiting process of a virtual machine according to an embodiment of the present disclosure;

as shown in fig. 3B, the client may send a virtual network card adding request to the server, where the updating request may include a second virtual machine identifier and a second virtual network card identifier. After receiving the virtual network card update request, the server may store the second virtual machine identifier and the second virtual network card identifier in the database. Then, the server may send a virtual network card update instruction to vgw, so that vgw may update the virtual network card associated with the second virtual machine according to the identifier of the second virtual machine and the identifier of the second virtual network card.

In addition, the server may also check whether the second virtual machine has corresponding second speed limit information, and if so, may send a virtual network card speed limit configuration instruction, so that vgw may update the speed limit information of the newly added virtual network card. In addition, the server can also return and display the information of successful virtual network card addition to the client.

According to the embodiment of the disclosure, a virtual network card update request may be received first, then, an association table between a preset virtual machine identifier and a virtual network card identifier may be updated based on a second virtual machine identifier and the second virtual network card identifier, a virtual network card unbinding instruction is sent to vgw when the virtual network card update request is a virtual network card unbinding request, second speed limit information corresponding to the second virtual machine identifier is obtained when the virtual network card update request is a virtual network card newly-adding request, and a virtual network card speed limit configuration instruction is sent to vgw. Therefore, by analyzing the virtual network card updating request, the updating requirement of the virtual network card associated with the virtual machine can be determined, and then the corresponding updating instruction can be sent to vgw, so that the virtual network card associated with the virtual machine can be updated, the complexity of updating the virtual network card is reduced, the updating of the virtual network card is simpler and easier, the perception interference caused to a user is reduced, the user experience is improved, and the operation of the user is facilitated.

Fig. 4 is a flowchart illustrating a method for limiting a flow rate of a virtual machine according to an embodiment of the present disclosure. As shown in fig. 4, the method for limiting the flow rate of the virtual machine may include the following steps:

step 401, receiving a virtual network card speed limit configuration instruction sent by a server, wherein the speed limit configuration instruction includes an identifier of a first virtual network card and speed limit information.

Vgw may determine the identifier and the speed limit information of the first virtual network card included therein by analyzing the received virtual network card speed limit configuration instruction sent by the server.

Optionally, the speed limit information may include at least one of: the speed limit type and a threshold value corresponding to each speed limit type.

For example, vgw analyzes the received virtual network card speed limit configuration command sent by the server to determine that "vm 03, n" is included, it may be determined that the identifier of the first virtual network card is "vm 03" and the corresponding speed limit information "speed is less than or equal to n".

For example, vgw analyzes the received speed limit configuration instruction of the virtual network card sent by the server to determine that the received speed limit configuration instruction includes "vm 02, vm03 and NAT", and then may determine that the identifier of the first virtual network card is "vm 02, vm 03" and the corresponding speed limit information "limit the NAT".

It should be noted that the above example is only an illustrative example, and cannot be used as a limitation on the identification of the first virtual network card, the speed limit information, and the like in the embodiment of the present disclosure.

And 402, updating the speed limit strategy of the first virtual network card corresponding to the identifier of the first virtual network card based on the speed limit information.

It can be understood that vgw, after receiving the virtual network card speed-limiting configuration instruction sent by the server, may determine the first virtual network card identifier and the speed-limiting information included in the speed-limiting configuration instruction by analyzing the virtual network card speed-limiting configuration instruction, and may then update the speed-limiting policy of the first virtual network card.

For example, if the identifier of the first virtual network card is "vm 1" and the speed limit information is "n", the speed limit policy of the first virtual network card may be updated, for example, the speed limit threshold of the first virtual network card "vm 1" is updated to "n".

It should be noted that the above example is only an illustrative example, and cannot be used as a limitation on the identifier of the first virtual network card, the speed limit information, and the like in the embodiment of the present disclosure.

It can be understood that the association relationship between the virtual machine and the virtual network card can also be updated.

Optionally, a virtual network card update instruction sent by the server may be received first, where the update instruction includes the target virtual machine identifier and the second virtual network card identifier, and then the virtual network card associated with the target virtual machine identifier may be updated according to the second virtual network card identifier.

When the virtual network card of the virtual machine needs to be deleted or added, a virtual network card update instruction may be sent to vgw, so that the vgw may determine the corresponding target virtual machine identifier and the second virtual network card identifier by analyzing the received virtual network card update instruction sent by the server.

In addition, the style or presentation form identified by the target virtual machine may be set in advance, for example, the style or presentation form may be: virtual machine 1, vm2, etc., to which this disclosure is not limited.

In addition, the style or presentation form of the identifier of the second virtual network card may be set in advance, for example, the style or presentation form may be as follows: a second virtual network card 1, a virtual network card 02, etc., which are not limited in this disclosure.

Optionally, the virtual network card update instruction may be multiple, for example, the virtual network card update instruction may be a virtual network card unbinding instruction, or may also be a virtual network card adding instruction, and the like, which is not limited in this disclosure.

For example, by analyzing the virtual network card update instruction sent by the server, it is determined that the target virtual machine identifier included in the virtual network card update instruction is "vm 1" and the second virtual network card identifier is "03", and if the virtual network card associated with the current target virtual machine "vm 1" does not include the second virtual network card "03", the "vm 1" and the second virtual network card "03" may be bound, so that the updated virtual network card associated with the "vm 1" includes the second virtual network card "03".

Or analyzing the virtual network card update instruction sent by the server to determine that the update instruction is a unbinding instruction, and if the target virtual machine identifier contained in the unbinding instruction is "vm 1" and the second virtual network card identifier contained in the unbinding instruction is "01", unbinding the target virtual machine "vm 1" and the second virtual network card "01", so that the updated "vm 1" and the second virtual network card "01" are disassociated.

Or, the update instruction sent by the server is analyzed to determine that the update instruction is a new instruction, and if the target virtual machine identifier included in the update instruction is "vm 2" and the second virtual network card identifier is "03", the target virtual machine "vm 2" and the second virtual network card "03" may be bound, so that the second virtual network card "03" is the new virtual network card associated with the target virtual machine "vm 2".

It should be noted that, the foregoing examples are only illustrative, and cannot be used as limitations on the second virtual network card identifier, the target virtual machine identifier, and the like in the embodiments of the present disclosure.

Therefore, in the embodiment of the disclosure, the virtual network card updating instruction sent by the server may be received first, and then the virtual network card associated with the target virtual machine identifier is updated according to the second virtual network card identifier, so that the virtual network card associated with the virtual machine may be updated, the complexity of updating the virtual network card associated with the virtual machine is reduced, and the complexity of limiting the flow rate of the virtual machine is also reduced.

According to the embodiment of the disclosure, a virtual network card speed-limiting configuration instruction sent by a server side can be received first, wherein the speed-limiting configuration instruction includes an identifier of a first virtual network card and speed-limiting information, and then a speed-limiting strategy of the first virtual network card corresponding to the identifier of the first virtual network card can be updated based on the speed-limiting information.
