[0001] The embodiments of the present invention relate to the field of cloud computing technology, and in particular to a bandwidth adjustment method, apparatus, device, storage medium and product. Background Technology

[0002] In modern data center and cloud computing environments, distributed storage systems are responsible for processing and storing massive amounts of data. With ever-increasing business demands, distributed storage systems face growing challenges, particularly in input / output (I / O) bandwidth management.

[0003] I / O bandwidth is one of the key limiting factors for storage system performance, directly affecting data access speed and overall system throughput. Traditional distributed storage systems typically use methods based on fixed threshold parameters to adjust the I / O bandwidth of each data transmission service, which suffers from poor adaptability. Summary of the Invention

[0004] This invention provides a bandwidth adjustment method, apparatus, device, storage medium, and product to solve the problem of poor bandwidth adaptability for data transmission services.

[0005] In a first aspect, embodiments of the present invention provide a bandwidth adjustment method, comprising:

[0006] The system obtains the weighted bandwidth requirement of multiple data transmission services, the real-time bandwidth requirement of multiple data transmission services, and the basic bandwidth requirement of multiple data transmission services, wherein the weighted bandwidth requirement is determined according to the priority of the corresponding data transmission services.

[0007] For each data transmission service, the adjusted bandwidth of the data transmission service is determined based on the weighted bandwidth requirement of the data transmission service, the real-time bandwidth requirement of the data transmission service, and the basic bandwidth requirement of the data transmission service.

[0008] If the adjusted bandwidth based on multiple data transmission services is determined to meet the preset bandwidth adjustment stop condition, then bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services.

[0009] Secondly, embodiments of the present invention also provide a bandwidth adjustment device, the device comprising:

[0010] The data transmission service bandwidth acquisition module is used to acquire the weighted demand bandwidth of multiple data transmission services, the real-time demand bandwidth of multiple data transmission services, and the basic demand bandwidth of multiple data transmission services, wherein the weighted demand bandwidth is determined according to the priority of the corresponding data transmission services.

[0011] The data transmission service bandwidth adjustment module is used to determine the adjusted bandwidth of each data transmission service based on the weighted demand bandwidth of the data transmission service, the real-time demand bandwidth of the data transmission service, and the basic demand bandwidth of the data transmission service.

[0012] The bandwidth adjustment stop determination module is used to allocate bandwidth based on the adjusted bandwidth of the multiple data transmission services if the adjusted bandwidth based on the multiple data transmission services is determined to meet the preset bandwidth adjustment stop condition.

[0013] Thirdly, embodiments of the present invention also provide an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the bandwidth adjustment method as described in any of the embodiments of the present invention.

[0014] Fourthly, embodiments of the present invention also provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the bandwidth adjustment method as described in any of the embodiments of the present invention.

[0015] Fifthly, embodiments of the present invention also provide a computer program product, including a computer program that, when executed by a processor, implements the bandwidth adjustment method as described in any of the embodiments of the present invention.

[0016] In this embodiment of the invention, the weighted bandwidth demand, real-time bandwidth demand, and basic bandwidth demand of multiple data transmission services are obtained. The weighted bandwidth demand is determined according to the priority of the corresponding data transmission services. For each data transmission service, the adjusted bandwidth is determined based on the weighted bandwidth demand, real-time bandwidth demand, and basic bandwidth demand. If the adjusted bandwidth of multiple data transmission services meets a preset bandwidth adjustment stop condition, bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services. This invention, by dynamically adjusting bandwidth based on weighted and real-time bandwidth demand, avoids bandwidth waste or insufficiency compared to fixed bandwidth allocation. It ensures reasonable allocation and use of bandwidth resources when data transmission service bandwidth demand fluctuates, thereby improving the adaptability of data transmission service bandwidth.

[0030] Before introducing specific embodiments, the application scenarios of the bandwidth adjustment method are described. The bandwidth adjustment method is applicable to situations requiring dynamic adjustment of I / O bandwidth in distributed storage systems. For example, Figure 1 This is a schematic diagram of a distributed storage system provided in an embodiment of the present invention. The distributed storage system includes a virtual machine cluster, a snapshot cluster, a storage pool, and a switch, etc. The storage pool may include multiple storage nodes, the virtual machine cluster is connected to the snapshot cluster, and the virtual machine cluster is connected to the storage nodes through a switch.

[0031] Figure 2 This is a flowchart illustrating a bandwidth adjustment method provided in an embodiment of the present invention. This embodiment is applicable to the dynamic adjustment of I / O bandwidth in distributed storage systems. The method can be executed by a bandwidth adjustment device, which can be implemented in hardware and / or software and can be configured in devices such as servers. Figure 2 As shown, the method includes:

[0032] S110. Obtain the weighted bandwidth requirement of multiple data transmission services, the real-time bandwidth requirement of multiple data transmission services, and the basic bandwidth requirement of multiple data transmission services, wherein the weighted bandwidth requirement is determined according to the priority of the corresponding data transmission services.

[0033] In this embodiment, data transmission service refers to the service that requires data transmission in the distributed storage system. For example, data transmission service can be application input / output service issued from virtual machine, snapshot input / output service for migrating from storage pool to snapshot cluster, migration input / output service when storage pool fails, and migration input / output service in case of data rebalancing or system upgrade, etc., and is not specifically limited here.

[0034] Weighted bandwidth demand is determined based on the priority of the corresponding data transmission services. In other words, the weight of data transmission services can be determined based on their priority, and then the weighted bandwidth demand can be determined based on those weights. The priority can be determined based on the service type, service level agreement (SLA), or other business rules of the data transmission service; no specific limitations are made here. Real-time bandwidth demand represents the current load of the data transmission service. In other words, real-time bandwidth demand refers to the bandwidth requirement of the data transmission service as monitored in real time, which can be calculated based on performance indicators such as service throughput, read / write operations per second, or data transmission rate. Basic bandwidth demand represents the basic load of the data transmission service. In other words, basic bandwidth demand refers to the amount of bandwidth required for the data transmission service to operate under normal or baseline conditions. It can be obtained through analysis of historical performance data, such as the average, median, or other statistical measures of historical performance data; no specific limitations are made here.

[0035] S120. For each data transmission service, the adjusted bandwidth of the data transmission service is determined based on the weighted required bandwidth of the data transmission service, the real-time required bandwidth of the data transmission service, and the basic required bandwidth of the data transmission service.

[0036] In this embodiment, for each data transmission service, the weighted bandwidth requirement, the real-time bandwidth requirement, and the basic bandwidth requirement are calculated to obtain the adjusted bandwidth of the data transmission service. The calculation method is not specifically limited here.

[0037] S130. If the adjusted bandwidth based on multiple data transmission services is determined to meet the preset bandwidth adjustment stop condition, then bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services.

[0038] In this embodiment, the preset bandwidth adjustment stop condition can be that the sum of the adjusted bandwidths of multiple data transmission services is less than or equal to the rated bandwidth, or that the adjusted bandwidths of multiple data transmission services are each less than a preset bandwidth value, etc., and no specific limitation is made here.

[0039] Specifically, after determining that the preset bandwidth adjustment stop condition is met, the adjusted bandwidth of the data transmission service can be allocated to the corresponding data transmission service to improve the bandwidth adaptability of the data transmission service.

[0040] In this embodiment of the invention, the weighted bandwidth demand, real-time bandwidth demand, and basic bandwidth demand of multiple data transmission services are obtained. The weighted bandwidth demand is determined according to the priority of the corresponding data transmission services. For each data transmission service, the adjusted bandwidth is determined based on the weighted bandwidth demand, real-time bandwidth demand, and basic bandwidth demand. If the adjusted bandwidth of multiple data transmission services meets a preset bandwidth adjustment stop condition, bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services. This invention, by dynamically adjusting bandwidth based on weighted and real-time bandwidth demand, avoids bandwidth waste or insufficiency compared to fixed bandwidth allocation. It ensures reasonable allocation and use of bandwidth resources when data transmission service bandwidth demand fluctuates, thereby improving the adaptability of data transmission service bandwidth.

[0041] Figure 3 This is a flowchart illustrating a bandwidth adjustment method provided in an embodiment of the present invention. The method in this embodiment can be combined with various optional schemes in the bandwidth adjustment methods provided in the above embodiments. The bandwidth adjustment method provided in this embodiment has been further optimized. Optionally, the data transmission service includes two or more of the following: application input / output service originating from the virtual machine, snapshot input / output service migrating from the storage pool to the snapshot cluster, and migration input / output service in case of storage pool failure. Figure 3 As shown, the method includes:

[0042] S210. Obtain the weighted bandwidth requirement of multiple data transmission services, the real-time bandwidth requirement of multiple data transmission services, and the basic bandwidth requirement of multiple data transmission services. The data transmission services include two or more of the following: application input / output services issued from the virtual machine, snapshot input / output services migrated from the storage pool to the snapshot cluster, and migration input / output services when the storage pool fails.

[0043] S220. For each data transmission service, the adjusted bandwidth of the data transmission service is determined based on the weighted required bandwidth of the data transmission service, the real-time required bandwidth of the data transmission service, and the basic required bandwidth of the data transmission service.

[0044] S230. If the adjusted bandwidth based on multiple data transmission services meets the preset bandwidth adjustment stop condition, then bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services.

[0045] In this embodiment, application input / output services originating from the virtual machine refer to input / output services generated by daily application operations, requiring a preset level of bandwidth to ensure operation. Snapshot input / output services migrating from the storage pool to the snapshot cluster refer to services such as creating data replicas, requiring a preset level of temporary bandwidth to ensure operation. Storage pool failures can be hard drive failures and / or node failures, which require additional bandwidth to ensure data migration.

[0046] It should be noted that by adaptively adjusting two or more of the following: application input / output services originating from virtual machines, snapshot input / output services migrating from the storage pool to the snapshot cluster, and migration input / output services in the event of a storage pool failure, reasonable allocation and use of bandwidth resources are achieved. Here, a storage pool failure can be a hard drive failure and / or a node failure.

[0047] Optionally, obtaining the weighted bandwidth requirement, the real-time bandwidth requirement, and the basic bandwidth requirement of multiple data transmission services includes: obtaining the weighted bandwidth requirement, the real-time bandwidth requirement, and the basic bandwidth requirement of the application input / output service originating from the virtual machine; obtaining the weighted bandwidth requirement, the real-time bandwidth requirement, and the basic bandwidth requirement of the snapshot input / output service migrated from the storage pool to the snapshot cluster; and obtaining the weighted bandwidth requirement, the real-time bandwidth requirement, and the basic bandwidth requirement of the migration input / output service when the storage pool fails.

[0048] Accordingly, for each data transmission service, determining the adjusted bandwidth of the data transmission service based on the weighted required bandwidth, the real-time required bandwidth, and the basic required bandwidth of the data transmission service includes: determining the adjusted bandwidth of the application input / output service originating from the virtual machine based on the weighted required bandwidth, the real-time required bandwidth, and the basic required bandwidth of the application input / output service originating from the virtual machine; determining the adjusted bandwidth of the snapshot input / output service migrating from the storage pool to the snapshot cluster based on the weighted required bandwidth, the real-time required bandwidth, and the basic required bandwidth of the snapshot input / output service migrating from the storage pool to the snapshot cluster; and determining the adjusted bandwidth of the migration input / output service during storage pool failure based on the weighted required bandwidth, the real-time required bandwidth, and the basic required bandwidth of the migration input / output service during storage pool failure.

[0049] Accordingly, if the adjusted bandwidth of multiple data transmission services meets the preset bandwidth adjustment stop condition, then bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services, including: determining the sum of the adjusted bandwidth of each data transmission service based on the adjusted bandwidth of the application input / output service issued from the virtual machine, the adjusted bandwidth of the snapshot input / output service migrated from the storage pool to the snapshot cluster, and the adjusted bandwidth of the migration input / output service when the storage pool fails; if the sum of the adjusted bandwidth of each data transmission service meets the preset bandwidth adjustment stop condition, then bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services.

[0050] In this embodiment, bandwidth adjustment is performed simultaneously on three services: application input / output services issued from the virtual machine, snapshot input / output services migrated from the storage pool to the snapshot cluster, and migration input / output services in case of storage pool failure. This achieves reasonable allocation and use of bandwidth resources.

[0051] Optionally, obtaining the weighted bandwidth requirement of the application input / output service issued from the virtual machine includes: obtaining the average bandwidth of the application input / output service issued from the virtual machine and the weight of the application input / output service issued from the virtual machine; and determining the weighted bandwidth requirement of the application input / output service issued from the virtual machine based on the average bandwidth of the application input / output service issued from the virtual machine and the weight of the application input / output service issued from the virtual machine.

[0052] Accordingly, obtaining the weighted bandwidth requirement of the snapshot input / output services migrated from the storage pool to the snapshot cluster includes: obtaining the average bandwidth of the snapshot input / output services migrated from the storage pool to the snapshot cluster and the weight of the snapshot input / output services migrated from the storage pool to the snapshot cluster; and determining the weighted bandwidth requirement of the snapshot input / output services migrated from the storage pool to the snapshot cluster based on the average bandwidth of the snapshot input / output services migrated from the storage pool to the snapshot cluster and the weight of the snapshot input / output services migrated from the storage pool to the snapshot cluster.

[0053] Accordingly, obtaining the weighted required bandwidth of the migration input / output service when the storage pool fails includes: obtaining the average bandwidth of the migration input / output service and the weight of the migration input / output service when the storage pool fails; and determining the weighted required bandwidth of the migration input / output service when the storage pool fails based on the average bandwidth of the migration input / output service and the weight of the migration input / output service when the storage pool fails.

[0054] In this embodiment, the average bandwidth refers to the average of multiple historical bandwidths under normal operating conditions for data transmission services.

[0055] For example, the formula for calculating the weighted bandwidth demand can be as follows:

[0056] BWdemand_i = Bi × Wi;

[0057] Where BWdemand_i represents the weighted bandwidth demand of data transmission service i, Bi represents the average bandwidth of data transmission service i, and Wi represents the weight of data transmission service i.

[0058] Optionally, the preset bandwidth adjustment stop condition includes: the total bandwidth of each data transmission service after adjustment is less than or equal to the rated bandwidth.

[0059] For example, if the total adjusted bandwidth of each data transmission service is less than or equal to the rated bandwidth, then the adjustment of the bandwidth of each data transmission service is stopped; if the total adjusted bandwidth of each data transmission service is greater than the rated bandwidth, then the adjusted bandwidth of each data transmission service is reduced so that the bandwidth meets the preset bandwidth adjustment stop condition.

[0060] Optionally, after determining the sum of adjusted bandwidths for each data transmission service based on the adjusted bandwidth of the application input / output service originating from the virtual machine, the adjusted bandwidth of the snapshot input / output service migrating from the storage pool to the snapshot cluster, and the adjusted bandwidth of the migration input / output service during storage pool failure, the method further includes: if the total adjusted bandwidth of each data transmission service does not meet a preset bandwidth adjustment stop condition, then based on a preset ratio, reducing the adjusted bandwidth of the application input / output service originating from the virtual machine, the adjusted bandwidth of the snapshot input / output service migrating from the storage pool to the snapshot cluster, and the adjusted bandwidth of the migration input / output service during storage pool failure, respectively, to obtain the adjusted reduced bandwidth of the application input / output service originating from the virtual machine, the adjusted reduced bandwidth of the snapshot input / output service migrating from the storage pool to the snapshot cluster, and the adjusted reduced bandwidth of the migration input / output service during storage pool failure.

[0061] It should be noted that, based on preset ratios, the adjusted bandwidth of application input / output services originating from virtual machines, the adjusted bandwidth of snapshot input / output services migrating from the storage pool to the snapshot cluster, and the adjusted bandwidth of migration input / output services during storage pool failures are reduced respectively. This ensures that the bandwidth of each data transmission service is reasonably allocated and used, thereby improving the utilization efficiency of network bandwidth resources.

[0062] For example, the formula for calculating the preset ratio can be:

[0063] R = (BW) A +BW B +BW C ) / BW total ;

[0064] Where R represents the preset ratio, BW A BW represents the regulated bandwidth of application input / output traffic originating from the virtual machine. B BW represents the regulated bandwidth for snapshot input / output services migrating from the storage pool to the snapshot cluster. C BW represents the adjusted bandwidth for migrating I / O services in the event of a storage pool failure. total Indicates the rated bandwidth.

[0065] BWadjustedA =BW A / R;

[0066] BW adjustedB =BW B / R;

[0067] BW adjustedC =BW C / R;

[0068] BW adjustedA +BW adjustedB +BW adjustedC ≤BW total ;

[0069] Among them, BW adjustedA BW represents the reduced bandwidth of application input / output traffic originating from the virtual machine. adjustedB This indicates the adjusted and reduced bandwidth for snapshot input / output services migrating from the storage pool to the snapshot cluster, BW. adjustedC This indicates the reduced bandwidth after migrating input / output services in the event of a storage pool failure.

[0070] Optionally, after obtaining the adjusted and reduced bandwidth of the application input / output service originating from the virtual machine, the adjusted and reduced bandwidth of the snapshot input / output service migrating from the storage pool to the snapshot cluster, and the adjusted and reduced bandwidth of the migration input / output service in the event of a storage pool failure, the method further includes: if the adjusted and reduced bandwidth of the application input / output service originating from the virtual machine is less than a first basic operating bandwidth, then setting the bandwidth of the application input / output service originating from the virtual machine to the first basic operating bandwidth; if the adjusted and reduced bandwidth of the snapshot input / output service migrating from the storage pool to the snapshot cluster is less than a second basic operating bandwidth, then setting the bandwidth of the snapshot input / output service migrating from the storage pool to the snapshot cluster to the second basic operating bandwidth; if the adjusted and reduced bandwidth of the migration input / output service in the event of a storage pool failure is less than a third basic operating bandwidth, then setting the bandwidth of the migration input / output service in the event of a storage pool failure to the third basic operating bandwidth.

[0071] The first basic operating bandwidth is the guaranteed bandwidth for application input / output services originating from the virtual machine, ensuring the operation of such services. Similarly, the second basic operating bandwidth is the guaranteed bandwidth for snapshot input / output services migrating from the storage pool to the snapshot cluster, ensuring their operation. The third basic operating bandwidth is the guaranteed bandwidth for migration input / output services in the event of a storage pool failure, ensuring their operation in the event of a storage pool failure.

[0072] It should be noted that when the bandwidth of the data transmission service after adjustment and reduction is less than the basic operating bandwidth, setting the bandwidth of the data transmission service to the basic operating bandwidth can avoid insufficient bandwidth for the data transmission service.

[0073] Figure 4 This is a flowchart illustrating a bandwidth adjustment method provided in an embodiment of the present invention. The method in this embodiment can be combined with various optional schemes in the bandwidth adjustment methods provided in the above embodiments. The bandwidth adjustment method provided in this embodiment has been further optimized. Optionally, obtaining the weighted demand bandwidth of multiple data transmission services includes: for each data transmission service, determining the weight of the data transmission service based on its priority; and determining the weighted demand bandwidth of the data transmission service based on its weight and the average bandwidth of the data transmission service. Figure 4 As shown, the method includes:

[0074] S310. For each data transmission service, determine the weight of the data transmission service based on its priority; determine the weighted bandwidth requirement of the data transmission service based on its weight and its average bandwidth.

[0075] S320: Obtain the real-time bandwidth requirements of multiple data transmission services and the basic bandwidth requirements of multiple data transmission services.

[0076] S330. For each data transmission service, the adjusted bandwidth of the data transmission service is determined based on the weighted required bandwidth of the data transmission service, the real-time required bandwidth of the data transmission service, and the basic required bandwidth of the data transmission service.

[0077] S340. If the adjusted bandwidth based on multiple data transmission services is determined to meet the preset bandwidth adjustment stop condition, then bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services.

[0078] In this embodiment, the priority of data transmission services is proportional to the weight of data transmission services.

[0079] For example, the formula for calculating weighted demand bandwidth can be as follows:

[0080] Wi = βQi;

[0081] BWdemand_i = Bi × Wi;

[0082] Where Qi represents the priority of data transmission service i, which is between 0 and 1; β represents the weight conversion coefficient; BWdemand_i represents the weighted bandwidth demand of data transmission service i; Bi represents the average bandwidth of data transmission service i; and Wi represents the weight of data transmission service i.

[0083] In this embodiment of the invention, the weight of data transmission services is determined based on their priority. Then, based on the weight of the data transmission service and its average bandwidth, the weighted bandwidth requirement of the data transmission service is determined, achieving priority-based bandwidth allocation and improving the adaptability of task bandwidth.

[0084] Figure 5 This is a flowchart illustrating a bandwidth adjustment method provided in an embodiment of the present invention. The method in this embodiment can be combined with various optional schemes in the bandwidth adjustment methods provided in the above embodiments. The bandwidth adjustment method provided in this embodiment has been further optimized. Optionally, determining the adjusted bandwidth of the data transmission service based on the weighted demand bandwidth of the data transmission service, the real-time demand bandwidth of the data transmission service, and the basic demand bandwidth of the data transmission service includes: determining the load variation bandwidth of the data transmission service based on the real-time demand bandwidth of the data transmission service and the basic demand bandwidth of the data transmission service; and determining the adjusted bandwidth of the data transmission service based on the load variation bandwidth of the data transmission service and the weighted demand bandwidth of the data transmission service. Figure 5 As shown, the method includes:

[0085] S410. Obtain the weighted bandwidth requirement of multiple data transmission services, the real-time bandwidth requirement of multiple data transmission services, and the basic bandwidth requirement of multiple data transmission services, wherein the weighted bandwidth requirement is determined according to the priority of the corresponding data transmission services.

[0086] S420. For each data transmission service, determine the load-varying bandwidth of the data transmission service based on the real-time demand bandwidth and the basic demand bandwidth of the data transmission service; determine the adjusted bandwidth of the data transmission service based on the load-varying bandwidth and the weighted demand bandwidth of the data transmission service.

[0087] S430. If the adjusted bandwidth based on multiple data transmission services is determined to meet the preset bandwidth adjustment stop condition, then bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services.

[0088] In this embodiment, load variation bandwidth refers to the bandwidth change caused by load fluctuations in data transmission services.

[0089] It should be noted that by monitoring the load changes of each service and adjusting the bandwidth accordingly, the available network bandwidth resources can be utilized more effectively.

[0090] Optionally, the formula for determining the adjusted bandwidth of the data transmission service is: Load change bandwidth of data transmission service = Real-time demand bandwidth of data transmission service - Basic demand bandwidth of data transmission service; Adjusted bandwidth of data transmission service = Weighted demand bandwidth of data transmission service + α × Load change bandwidth of data transmission service; where α represents the adjustment factor.

[0091] In this embodiment of the invention, the load-change bandwidth of the data transmission service is determined based on the real-time demand bandwidth and the basic demand bandwidth of the data transmission service. Then, the adjusted bandwidth of the data transmission service is determined based on the load-change bandwidth and the weighted demand bandwidth of the data transmission service. This realizes the automatic adjustment of the bandwidth of the data transmission service, so that bandwidth resources are rationally allocated and used, thereby improving the adaptability of the bandwidth of the data transmission service.

[0092] Figure 6 This is a flowchart illustrating a bandwidth adjustment method provided in an embodiment of the present invention. The method in this embodiment can be combined with various optional schemes in the bandwidth adjustment methods provided in the above embodiments. The bandwidth adjustment method provided in this embodiment has been further optimized. Optionally, after determining the adjusted bandwidth of the data transmission service based on the weighted demand bandwidth of the data transmission service, the real-time demand bandwidth of the data transmission service, and the basic demand bandwidth of the data transmission service, the method further includes: for any data transmission service, if the adjusted bandwidth of the data transmission service meets a preset bandwidth allocation condition, then determining the allocable bandwidth based on the weighted demand bandwidth of the data transmission service; and adjusting the bandwidth of each data transmission service based on the allocable bandwidth. Figure 6 As shown, the method includes:

[0093] S510. Obtain the weighted bandwidth requirement of multiple data transmission services, the real-time bandwidth requirement of multiple data transmission services, and the basic bandwidth requirement of multiple data transmission services, wherein the weighted bandwidth requirement is determined according to the priority of the corresponding data transmission services.

[0094] S520. For each data transmission service, the adjusted bandwidth of the data transmission service is determined based on the weighted required bandwidth of the data transmission service, the real-time required bandwidth of the data transmission service, and the basic required bandwidth of the data transmission service.

[0095] S530. If the adjusted bandwidth based on multiple data transmission services is determined to meet the preset bandwidth adjustment stop condition, then bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services.

[0096] S540. For any data transmission service, if the adjusted bandwidth of the data transmission service meets the preset bandwidth allocation conditions, then the allocable bandwidth is determined based on the weighted demand bandwidth of the data transmission service; based on the allocable bandwidth, the bandwidth of each data transmission service is adjusted.

[0097] The preset bandwidth allocation conditions refer to the pre-set bandwidth redistribution conditions. Specifically, the preset bandwidth allocation conditions can be that the adjusted bandwidth of the data transmission service is greater than or equal to the minimum bandwidth of the data transmission service, etc., without further specific limitations.

[0098] For example, data transmission services may include data transmission service A, data transmission service B, and data transmission service C. Data transmission service A has a guaranteed bandwidth of bA, data transmission service B has a guaranteed bandwidth of bB, and data transmission service C has a guaranteed bandwidth of bC. If the adjusted bandwidth of data transmission service A is greater than the guaranteed bandwidth of bA, then the weighted required bandwidth of data transmission service A minus the guaranteed bandwidth of data transmission service A is used to obtain the allocable bandwidth. This allocable bandwidth is then allocated to data transmission services B and C to improve the overall data transmission rate of the services.

[0099] Figure 7 This is a flowchart illustrating a bandwidth adjustment method provided in an embodiment of the present invention. Specifically, the priority of each data transmission service is obtained, and the weighted bandwidth requirement of each data transmission service is calculated based on its priority.

[0100] If the total weighted bandwidth requirement of each data transmission service exceeds the rated bandwidth, the weighted bandwidth requirement of each data transmission service will be reduced by a preset ratio. If the reduced bandwidth exceeds the minimum bandwidth, the process will return to determine if the total weighted bandwidth requirement of each data transmission service exceeds the rated bandwidth. If the reduced bandwidth does not exceed the minimum bandwidth, the bandwidth of the corresponding data transmission service will be set to the minimum bandwidth.

[0101] If the total weighted bandwidth demand of each data transmission service is not greater than the rated bandwidth, then the adjusted bandwidth of each data transmission service is calculated based on the weighted bandwidth demand of each data transmission service, the real-time bandwidth demand of each data transmission service, and the basic bandwidth demand of each data transmission service.

[0102] If the sum of the adjusted bandwidths of all data transmission services exceeds the rated bandwidth, the adjusted bandwidths of each data transmission service will be reduced by a preset ratio. If the reduced bandwidth is greater than the minimum guaranteed bandwidth, the process will return to determine if the sum of the adjusted bandwidths of all data transmission services exceeds the rated bandwidth; if the reduced bandwidth is not greater than the minimum guaranteed bandwidth, the bandwidth of the corresponding data transmission service will be set to the minimum guaranteed bandwidth.

[0103] If the sum of the adjusted bandwidths of each data transmission service does not exceed the rated bandwidth, then the adjustment of the bandwidth of each data transmission service will be terminated.

[0104] Figure 8 This is a schematic diagram of a bandwidth adjustment device provided in an embodiment of the present invention. Figure 8 As shown, the device includes:

[0105] The data transmission service bandwidth acquisition module 610 is used to acquire the weighted demand bandwidth of multiple data transmission services, the real-time demand bandwidth of multiple data transmission services, and the basic demand bandwidth of multiple data transmission services, wherein the weighted demand bandwidth is determined according to the priority of the corresponding data transmission services.

[0106] The data transmission service bandwidth adjustment module 620 is used to determine the adjusted bandwidth of each data transmission service based on the weighted demand bandwidth of the data transmission service, the real-time demand bandwidth of the data transmission service, and the basic demand bandwidth of the data transmission service.

[0107] The bandwidth adjustment stop determination module 630 is used to allocate bandwidth based on the adjusted bandwidth of the multiple data transmission services if the adjusted bandwidth based on the multiple data transmission services is determined to meet the preset bandwidth adjustment stop condition.

[0108] In this embodiment of the invention, the weighted bandwidth demand, real-time bandwidth demand, and basic bandwidth demand of multiple data transmission services are obtained. The weighted bandwidth demand is determined according to the priority of the corresponding data transmission services. For each data transmission service, the adjusted bandwidth is determined based on the weighted bandwidth demand, real-time bandwidth demand, and basic bandwidth demand. If the adjusted bandwidth of multiple data transmission services meets a preset bandwidth adjustment stop condition, bandwidth allocation is performed based on the adjusted bandwidth of the multiple data transmission services. This invention, by dynamically adjusting bandwidth based on weighted and real-time bandwidth demand, avoids bandwidth waste or insufficiency compared to fixed bandwidth allocation. It ensures reasonable allocation and use of bandwidth resources when data transmission service bandwidth demand fluctuates, thereby improving the adaptability of data transmission service bandwidth.

[0122] Obtain the average bandwidth and weight of the application input / output services emitted from the virtual machine; determine the weighted bandwidth requirement of the application input / output services emitted from the virtual machine based on the average bandwidth and weight of the application input / output services emitted from the virtual machine.

[0123] Correspondingly, the snapshot input / output service bandwidth acquisition unit, which migrates from the storage pool to the snapshot cluster, is specifically used for:

[0124] Obtain the average bandwidth and weight of the snapshot input / output services migrated from the storage pool to the snapshot cluster; determine the weighted bandwidth requirement of the snapshot input / output services migrated from the storage pool to the snapshot cluster based on the average bandwidth and weight of the snapshot input / output services migrated from the storage pool to the snapshot cluster.

[0131] In some alternative implementations, the bandwidth reduction unit is further configured to:

[0133] If the adjusted and reduced bandwidth of the snapshot input / output service migrated from the storage pool to the snapshot cluster is less than the second basic operating bandwidth, then the bandwidth of the snapshot input / output service migrated from the storage pool to the snapshot cluster is set to the second basic operating bandwidth.

[0134] If the adjusted bandwidth of the migration input / output service during a storage pool failure is less than the third basic operating bandwidth, then the bandwidth of the migration input / output service during a storage pool failure will be set to the third basic operating bandwidth.
