Description

Technical Field

[0001] The present application relates to the technical field of cloud computing, and in particular to a bandwidth allocation method, apparatus, device and storage medium. Background Art

[0002] In traditional cloud computing scenarios, users purchase computing nodes from cloud operators, who are responsible for running and maintaining the operating systems and applications on the computing nodes. When users purchase node processors and memory specifications, they also obtain the corresponding network bandwidth.

[0003] In the wave of cloud nativeization, more and more cloud users use serverless computing paradigms and container technology to deploy applications. However, in the serverless computing scenario, users can only specify the specifications of the processor and memory owned by the container. Because users are not aware of the computing node resources, containers corresponding to multiple users will be mixed and deployed on the same computing node, sharing the network bandwidth resources of the computing node. Therefore, containers in the same computing node will compete with each other for network bandwidth resources. Under the coordination of the network transmission control protocol (TCP) congestion control algorithm, containers with more network connections will occupy more bandwidth resources in the computing node. This will lead to unreasonable allocation of container bandwidth in the computing node and low bandwidth resource utilization. Summary of the invention

[0004] In view of the above problems, the present application provides a bandwidth allocation method, apparatus, device and storage medium to at least solve the technical problems of unreasonable allocation of container bandwidth in computing nodes and low bandwidth resource utilization in related technologies.

[0005] According to a first aspect of an embodiment of the present application, a bandwidth allocation method is provided, including: obtaining a network bandwidth of a computing node and a bandwidth configuration parameter of each container in the computing node; and allocating bandwidth for each container based on the network bandwidth of the computing node and the bandwidth configuration parameter of each container.

[0006] According to a second aspect of an embodiment of the present application, a bandwidth allocation device is provided. The above-mentioned information retrieval optimization device includes: an acquisition unit, which acquires the network bandwidth of a computing node and the bandwidth configuration parameters of each container in the computing node; an allocation unit, which is used to allocate bandwidth for use to each container based on the network bandwidth of the computing node and the bandwidth configuration parameters of each container.

[0007] According to a third aspect of an embodiment of the present application, an electronic device is also provided, including a memory and a processor, wherein the memory stores a computer program, and the processor is configured to execute the bandwidth allocation method of the first aspect through the computer program.

[0008] According to a fourth aspect of an embodiment of the present application, a computer-readable storage medium is further provided, in which a computer program is stored, wherein the computer program is configured to execute the bandwidth allocation method of the first aspect when running.

[0009] In an embodiment of the present application, a method is adopted in which the network bandwidth of a computing node and the bandwidth configuration parameters of each container in the computing node are obtained; and bandwidth is allocated to each container based on the network bandwidth of the computing node and the bandwidth configuration parameters of each container. When allocating bandwidth to each container of a computing node, the embodiment of the present application allocates bandwidth to each container based on the bandwidth configuration parameters of each container and the network bandwidth of the computing node, thereby preventing containers with more network connections from occupying more bandwidth resources in the computing node, and not only reasonably allocating the bandwidth of containers in the computing node, but also improving the utilization rate of bandwidth resources.

[0023] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only embodiments of a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] The following are explanations of the technical terms involved in this application:

[0026] Serverless computing: Serverless computing is a new cloud computing paradigm. In serverless computing, cloud users are not aware of the existence of servers and are not responsible for the maintenance of the operating system, so they can focus more on the development of application logic.

[0027] Container: A container is a lightweight application code package and a collection of dependencies and configurations required to run the application. Containers can be deployed on an operating system and run. Container technology has the advantages of strong portability and good isolation when distributing and deploying software. Containers are the technical foundation of cloud native and serverless computing.

[0028] Node: Node, also known as computing node, is a container deployment platform with independent processor, memory, network and other resources, capable of running a complete operating system. A computing node can be a physical server or a virtual machine.

[0029] Optionally, according to one aspect of the embodiments of the present application, a bandwidth allocation method is provided. As an optional implementation, the bandwidth allocation method can be applied to, but is not limited to, Figure 1 In the application environment shown. The application environment may include, but is not limited to: a terminal device 102 for human-computer interaction with a user, a network 110, and a cloud server cluster 112. Various cloud service clients are running in the terminal device 102. The terminal device 102 includes a display 108, a processor 106, and a memory 104. The display 108 is used to present the operation interface of the cloud service. The processor 106 is used to receive a cloud service operation instruction sent by a user, and the cloud service instruction includes the user's demand data or the service information selected by the user. The memory 104 is used to store the user's demand data or the service information selected by the user, as well as the feedback information from the cloud server cluster 112 sent by the cloud control platform 118. The cloud control platform 118 provides an access interface with the terminal device 102. The terminal device 102 sends the user's demand data and the service information selected by the user to the cloud control platform 118 through the network 110 and the access interface. The cloud control platform 118 sends the user's demand data and the service information selected by the user to the cloud server cluster 112 through the data center network. In addition, the cloud server cluster 112 includes a database 114 and a processing engine 116. The database 114 is used to store the user's demand data and the service information selected by the user, as well as the network bandwidth of the computing node and the bandwidth configuration parameters of each container. The processing engine 116 is used to obtain the network bandwidth of the computing node and the bandwidth configuration parameters of each container in the computing node; based on the network bandwidth of the computing node and the bandwidth configuration parameters of each container, the bandwidth is allocated to each container. The feedback information corresponding to the user's request for cloud service is returned to the cloud control platform 118, and the cloud control platform 118 sends the feedback information to the terminal device 102.

[0030] It should be noted that the cloud server cluster 112 may include one or more computing nodes, each computing node includes one or more containers, such as Figure 2As shown, the cloud server cluster 112 includes computing node 1 and computing node 2, and each computing node includes multiple containers. An application program or cloud service program is deployed in each container.

[0031] Optionally, the terminal device 102 includes but is not limited to a mobile phone, a laptop computer, a tablet computer, a PDA, a MID (Mobile Internet Devices), a desktop computer, a smart TV, etc. The network 110 may include but is not limited to: a wired network, a wireless network, wherein the wired network includes: a local area network, a metropolitan area network and a wide area network, and the wireless network includes but is not limited to: Bluetooth, WIFI and other networks that implement wireless communication. The cloud server cluster 112 may be a single server or a cloud server cluster consisting of multiple servers.

[0032] In the related technology, more and more cloud tenants use the serverless computing paradigm and utilize container technology to deploy applications. However, in the serverless computing scenario, users can only specify the specifications of the processor and memory owned by the container. Containers of multiple users will be deployed in the same computing node and share the network bandwidth resources of the computing node. Therefore, containers in the same computing node will compete with each other for network bandwidth resources. Under the coordination of the TCP congestion control algorithm of the network transmission control protocol, the more network connections a container has, the more bandwidth resources it will occupy in the computing node. This will lead to unreasonable allocation of container bandwidth in the computing node and low bandwidth resource utilization.

[0033] In order to solve the above technical problems, as an optional implementation method, Figure 3 As shown, the embodiment of the present application provides a bandwidth allocation method, comprising the following steps:

[0034] S302, obtaining the network bandwidth of the computing node and the bandwidth configuration parameters of each container in the computing node.

[0035] Specifically, in an embodiment of the present application, the bandwidth configuration parameters of each container in the computing node include but are not limited to the guaranteed bandwidth of each container, the burst bandwidth of each container (maximum quota bandwidth), the real-time bandwidth demand of each container, the reserved bandwidth of the current computing node (not participating in the bandwidth allocation of each container), the minimum allocated bandwidth of the container on the current computing node, and the total bandwidth actually allocated to each container. It should be noted that the bandwidth configuration parameters of each container correspond to the service attributes purchased by the user corresponding to the container. For example, when the service attributes purchased by the user include ordinary instances, the guaranteed bandwidth of the corresponding container is 2GB / s and the burst bandwidth is 5GB / s. When the service attributes purchased by the user include enhanced instances, the guaranteed bandwidth of the corresponding container is 3GB / s and the burst bandwidth is 7GB / s. In another example, the bandwidth configuration parameters of each container can also be configured based on the preset bandwidth.

[0036] S304: Allocate bandwidth for each container based on the network bandwidth of the computing node and the bandwidth configuration parameters of each container.

[0037] Specifically, for example, if the network bandwidth of the current computing node is 10 GB / s, and the current computing node includes two containers, such as container A and container B, then according to the bandwidth configuration parameters of container A and container B, the bandwidth allocated to container A is 2 GB / s, and the bandwidth allocated to container B is 6 GB / s; or the bandwidth allocated to container A is 5 GB / s, and the bandwidth allocated to container B is 5 GB / s. Here, the total bandwidth allocated to container A and container B does not exceed 10 GB / s.

[0038] In an embodiment of the present application, a method is adopted in which the network bandwidth of a computing node and the bandwidth configuration parameters of each container in the computing node are obtained; and bandwidth is allocated to each container based on the network bandwidth of the computing node and the bandwidth configuration parameters of each container. When allocating bandwidth to each container of a computing node, the embodiment of the present application allocates bandwidth to each container based on the bandwidth configuration parameters of each container and the network bandwidth of the computing node, thereby preventing containers with more network connections from occupying more bandwidth resources in the computing node, and not only reasonably allocating the bandwidth of containers in the computing node, but also improving the utilization rate of bandwidth resources.

[0039] In one or more embodiments, Figure 4 As shown, the embodiment of the present application also provides a bandwidth allocation method, comprising the following steps:

[0040] S402, obtaining the network bandwidth of the computing node and the bandwidth configuration parameters of each container in the computing node.

[0041] S404: when the sum of the guaranteed bandwidths of the containers is less than or equal to the network bandwidth of the computing node, obtain a current bandwidth demand of a first container, where the first container is any container among the containers;

[0042] S406: Taking the minimum value between the current demand and the guaranteed bandwidth of the first container as the first allocated bandwidth of the first container, and allocating a used bandwidth to the first container based on the first allocated bandwidth of the first container.

[0043] Specifically, in the embodiment of the present application, the input parameter verification module calculates whether the sum of the guaranteed bandwidths of each container is greater than the network bandwidth of the computing node. If the sum of the guaranteed bandwidths of each container is greater than the network bandwidth of the computing node, the container bandwidth allocation cannot guarantee that the configuration of the guaranteed bandwidth is met at any time, and the abnormal input processing module of the system is processed.

[0044] In one example, if the reserved bandwidth of the current computing node is configured with a corresponding value, the value obtained by subtracting the reserved bandwidth from the network bandwidth of the computing node is used as the allocated bandwidth resource of each container. It should be noted that when the preset minimum allocated bandwidth on the computing node is configured with a corresponding value, the maximum value of the sum of the guaranteed bandwidth of each container and the sum of the preset minimum allocated bandwidth of each container is determined, and the input parameter verification module is used to calculate whether the maximum value is greater than the network bandwidth of the computing node. If it is greater than the network bandwidth of the computing node, the bandwidth allocation of the container cannot guarantee that the bandwidth demand of the container is always met. At this time, the abnormal input processing module of the system can be entered for processing.

[0045] For example, the current computing node includes three containers, container A, whose guaranteed bandwidth is 1GB / s; container B, whose guaranteed bandwidth is 2GB / s; container C, whose guaranteed bandwidth is 3GB / s. The sum of the guaranteed bandwidths of the above containers is 6GB / s. When the sum of the guaranteed bandwidths of the above containers is less than or equal to the network bandwidth of the computing node 8GB / s, the current demand for bandwidth of the above containers is obtained, container A is 1.5GB / s, container B is 2.5GB / s, and container C is 2.5GB / s; the first allocated bandwidth of container A is 1GB / s, the first allocated bandwidth of container B is 2GB / s, and the first allocated bandwidth of container C is 2.5GB / s. The first allocated bandwidth of each of the above containers is determined as the usage bandwidth of the first container. Based on the above technical method, the bandwidth of the computing node can be reasonably allocated according to the guaranteed bandwidth and real-time required bandwidth corresponding to each container.

[0046] The above step S402 has been clearly explained in the previous text and will not be repeated here.

[0047] In one or more embodiments, Figure 5As shown, the embodiment of the present application also provides a bandwidth allocation method, comprising the following steps:

[0048] S502: Obtain the network bandwidth of a computing node and bandwidth configuration parameters of each container in the computing node.

[0049] S504: When the sum of the guaranteed bandwidths of the containers is less than or equal to the network bandwidth of the computing node, obtain a current bandwidth demand of a first container, where the first container is any container among the containers.

[0050] S506: Taking the minimum value between the current demand and the guaranteed bandwidth of the first container as the first allocated bandwidth of the first container;

[0051] S508: Determine a maximum value between the first allocated bandwidth and a preset minimum allocated bandwidth of the first container as a used bandwidth of the first container.

[0052] Specifically, in an embodiment of the present application, when the preset minimum allocated bandwidth on the computing node is configured with a corresponding value, by configuring the preset minimum allocated bandwidth, the situation where the container is interrupted due to a system bandwidth allocation error can be avoided. The preset minimum allocated bandwidth corresponding to each container on the computing node can be the same or different. Specifically, for example, the minimum value of the demand before container A in the current computing node and the guaranteed bandwidth of the first container is 2GB / s, container B is 3GB / s, and container C is 0.5GB / s. By configuring the preset minimum allocated bandwidth of 1.5GB / s, the bandwidth used by container C can be adjusted to 1.5GB / s, thereby avoiding network congestion or network interruption in container C.

[0053] The above steps S502 to S506 have been clearly explained in the previous text and will not be repeated here.

[0054] In one or more embodiments, Figure 6 As shown, the embodiment of the present application also provides a bandwidth allocation method, comprising the following steps:

[0055] S602, obtaining the network bandwidth of the computing node and the bandwidth configuration parameters of each container in the computing node.

[0056] S604: When the sum of the guaranteed bandwidths of the containers is less than or equal to the network bandwidth of the computing node, obtain a current bandwidth demand of a first container, where the first container is any container among the containers.

[0057] S606: Use a minimum value between the current demand and the guaranteed bandwidth of the first container as a first allocated bandwidth of the first container.

[0058] S608, determining a first sum value obtained by adding the first allocated bandwidths of the containers, and determining a difference value obtained by subtracting the first sum value from the network bandwidth of the computing node as a first remaining bandwidth of the computing node;

[0059] S610: When the first remaining bandwidth is greater than zero, calculate a second allocated bandwidth of the first container based on the first remaining bandwidth, a current demand of the first container, and the first allocated bandwidth of the first container; wherein the second allocated bandwidth of the first container is less than or equal to a preset maximum quota bandwidth of the first container.

[0060] S612: Determine a used bandwidth of the first container based on the sum of the first allocated bandwidth and the second allocated bandwidth of the first container.

[0061] Specifically, in the embodiment of the present application, for example, the current computing node includes three containers, A, B, and C. The first allocated bandwidth of container A is 1 GB / s, the first allocated bandwidth of container B is 2 GB / s, and the first allocated bandwidth of container C is 2 GB. The first sum value obtained by adding the first allocated bandwidths of each container is 5 GB / s. The difference obtained by subtracting the first sum value 5 GB / s from the network bandwidth of the computing node 8 GB / s is 3 GB / s, and the first remaining bandwidth of the computing node is 3 GB / s. Based on the first remaining bandwidth, the current demand of containers A, B, and C, the preset maximum quota bandwidth of containers A, B, and C, and the first allocated bandwidth of each container, the second allocated bandwidth of containers A, B, and C is calculated.

[0062] In one example, the second allocated bandwidth of the containers A, B, and C is calculated based on the maximum-minimum fairness algorithm, including but not limited to. Assume that the current bandwidth demands of the containers A, B, and C are 1.6 GB / s, 3.1 GB / s, and 3.5 GB / s, respectively, and the unsatisfied bandwidth demands of the three containers are 0.6 GB / s, 1.1 GB / s, and 1.5 GB / s, respectively. The present application continues to allocate bandwidth to the current containers A, B, and C through multiple rounds of calculations: in the first round, the first remaining bandwidth of 3 GB / s is temporarily divided into three resources of 1 GB / s and allocated to containers A, B, and C. Since this round of allocation exceeds the demand of container A, in the second round, the excess bandwidth of 0.4 GB / S of container A is evenly allocated to containers B and C, and 0.2 GB / S of bandwidth is given to each container B and C. This round of allocation exceeds the demand of container B by 0.1 GB / S, and container C still lacks 0.3 GB / S of bandwidth. The bandwidth of 0.1 GB / S is allocated to container C, and the second allocated bandwidths of containers A, B, and C are 0.6 GB / s, 1.1 GB / s, and 1.3 GB / s, respectively.

[0063] In another example, a weighted maximum-minimum fair allocation algorithm may be used to calculate the second allocated bandwidth of the containers A, B, and C. For example, assuming that the current bandwidth demands of containers A, B, and C are 1.6 GB / s, 3.1 GB / s, and 3.5 GB / s, respectively, and the unmet bandwidth demands of the three containers are 0.6 GB / s, 1.1 GB / s, and 1.5 GB / s, respectively, and the corresponding weights of the three containers are 1, 0.5, and 1.5, respectively. The first step is to standardize the weights, and set the minimum weight to 1, so that the weight set is updated to 2, 1, and 3. Assume that the required bandwidth resources are not 3 portions but 2+1+3=6 portions. Therefore, the bandwidth is divided into 6 portions. In each round of bandwidth allocation, resources are divided according to the proportion of weights; therefore, in the first round, containers A, B, and C obtain bandwidths of 1 GB / s, 0.5 GB / s, and 1.5 GB / s, respectively, and container A obtains a bandwidth of 1 GB / s, but only 0.6 GB / s is required, so there is an extra 0.4 GB / s. Container B is short of 0.6 GB / s, and container C just meets the demand, so 0.4 GB / s is allocated to container B. The second allocated bandwidths of containers A, B, and C are 0.6 GB / s, 0.9 GB / s, and 1.5 GB / s, respectively. In the embodiment of the present application, the weight corresponding to the above container can be the guaranteed bandwidth of the container or the preset maximum quota bandwidth of the container.

[0064] It should be noted that the bandwidth allocated to the container at this stage does not exceed the preset maximum quota bandwidth (burst bandwidth) of the container. According to the sum of the first allocated bandwidth and the second allocated bandwidth of the first container, the bandwidth used by each container can be accurately obtained.

[0065] Steps S602-S606 in the embodiment of the present application have been clearly explained in the previous text and will not be repeated here.

[0066] In one or more embodiments, calculating the second allocated bandwidth of the first container based on the first remaining bandwidth, the current demand of the first container, and the first allocated bandwidth of the first container includes:

[0067] Determining a bandwidth demand difference of each container based on the current demand of each container and the first allocated bandwidth;

[0068] According to the bandwidth requirement difference of each container, based on the maximum-minimum-fairness algorithm and the first remaining bandwidth, a second allocated bandwidth corresponding to the first container is determined.

[0069] Specifically, the embodiment of the present application calculates the second allocated bandwidth of containers A, B and C in the current computing node based on the maximum-minimum fairness algorithm. Assume that the current bandwidth demands of containers A, B and C are 1.6 GB / s, 3.1 GB / s and 3.5 GB / s respectively; the first allocated bandwidth of container A is 1 GB / s, the first allocated bandwidth of container B is 2 GB / s, and the first allocated bandwidth of container C is 2 GB; the unmet bandwidth demands (bandwidth demand differences) of the three containers are 0.6 GB / s, 1.1 GB / s and 1.5 GB / s respectively. The present application continues to allocate bandwidth to the current containers A, B, and C through multiple rounds of calculations: in the first round, the first remaining bandwidth of 3 GB / s is temporarily divided into three resources of 1 GB / s and allocated to containers A, B, and C. Since this round of allocation exceeds the demand of container A, in the second round, the excess bandwidth of 0.4 GB / S of container A is evenly allocated to containers B and C, and 0.2 GB / S of bandwidth is given to each container B and C. This round of allocation exceeds the demand of container B by 0.1 GB / S, and container C still lacks 0.3 GB / S of bandwidth. The bandwidth of 0.1 GB / S is allocated to container C, and the second allocated bandwidths of containers A, B, and C are 0.6 GB / s, 1.1 GB / s, and 1.3 GB / s, respectively.

[0070] In one or more embodiments, Figure 7 As shown, the embodiment of the present application also provides a bandwidth allocation method, comprising the following steps:

[0071] S702, obtaining the network bandwidth of the computing node and the bandwidth configuration parameters of each container in the computing node.

[0072] S704: When the sum of the guaranteed bandwidths of the containers is less than or equal to the network bandwidth of the computing node, obtain a current bandwidth demand of a first container, where the first container is any container among the containers.

[0073] S706: Use a minimum value between the current demand and the guaranteed bandwidth of the first container as a first allocated bandwidth of the first container.

[0074] S708, determining a first sum value obtained by adding the first allocated bandwidths of the containers, and determining a difference value obtained by subtracting the first sum value from the network bandwidth of the computing node as a first remaining bandwidth of the computing node;

[0075] S710: When the first remaining bandwidth is greater than zero, calculate a second allocated bandwidth of the first container based on the first remaining bandwidth, a current demand of the first container, and the first allocated bandwidth of the first container.

[0076] S712: Determine a second sum value obtained by adding the second allocated bandwidths of each container, and determine a difference value obtained by subtracting the second sum value from the first remaining bandwidth as a second remaining bandwidth of the computing node;

[0077] S714: When the second remaining bandwidth is greater than zero, determine a third allocated bandwidth of the first container;

[0078] S716: Determine the sum of the first allocated bandwidth, the second allocated bandwidth, and the third allocated bandwidth of the first container as the used bandwidth of the first container.

[0079] Specifically, in an embodiment of the present application, for example, the current computing node includes three containers, A, B, and C. The second allocated bandwidth of container A is 0.5 GB / s, the second allocated bandwidth of container B is 0.7 GB / s, and the second allocated bandwidth of container C is 1.3 GB. The first sum value obtained by adding the second allocated bandwidths of each container is 2.5 GB / s. The first remaining bandwidth of the computing node is 3 GB / s minus the first sum value 2.5 GB / s to obtain a second remaining bandwidth of 0.5 GB / s. The third allocated bandwidth of containers A, B, and C is determined according to the second remaining bandwidth. Finally, the sum of the first allocated bandwidth, the second allocated bandwidth, and the third allocated bandwidth of the three containers A, B, and C is determined as the usage bandwidth of the above-mentioned containers A, B, and C.

[0080] The above steps S702-S710 have been clearly explained in the previous text and will not be repeated here.

[0081] In one or more embodiments, determining the third allocated bandwidth of the first container includes: determining the third allocated bandwidth of the first container to be zero based on the usage bandwidth of the first container being greater than or equal to the current demand of the first container.

[0082] Specifically, in the embodiment of the present application, assuming that the current computing node includes three containers, namely, containers A, B, and C, and when the currently allocated bandwidth is greater than or equal to the current demand for bandwidth of each container, there is no need to allocate the remaining bandwidth of the current computing node to the above three containers A, B, and C.

[0083] In one or more embodiments, determining the third allocated bandwidth of the first container includes: calculating a ratio of the second remaining bandwidth to the total number of containers of each container, and determining the ratio as the third allocated bandwidth of the first container;

[0084] Alternatively, the guaranteed bandwidth or the preset maximum quota bandwidth of each container is used as the weight corresponding to each container, and the second remaining bandwidth is allocated based on the weight of each container to obtain the third allocated bandwidth of the first container.

[0085] Specifically, in the embodiment of the present application, assuming that the current computing node includes three containers A, B and C, and the second remaining bandwidth of the current computing node is 0.6 GB / s, 0.6 GB / s can be evenly distributed to the three containers A, B and C. That is, the third allocated bandwidths of the three containers A, B and C are all 0.2 GB / s.

[0086] In another example, the guaranteed bandwidth or the preset maximum quota bandwidth of each container is used as the weight corresponding to each container, assuming that the guaranteed bandwidths of containers A, B and C are their corresponding weights, and the weights of containers A, B and C are 1, 2 and 3. Based on the weight, the second remaining bandwidth of 0.6 GB / s is allocated, and the third allocated bandwidths of containers A, B and C are 0.1 GB / s, 0.2 GB / s and 0.3 GB / s respectively.

[0087] In one or more embodiments, Figure 8 As shown, the embodiment of the present application also provides a bandwidth allocation method, comprising the following steps:

[0088] S802, when the time interval between the current moment and the last bandwidth allocation moment reaches a preset time length, the step of obtaining the network bandwidth of the computing node and the bandwidth configuration parameters of each container in the computing node is executed; after the execution is completed, the step goes to step S806;

[0089] S804: When it is detected that the network of the computing node is in a congested state, the step of obtaining the network bandwidth of the computing node and the bandwidth configuration parameters of each container in the computing node is executed.

[0090] S806: Allocate bandwidth for each container based on the network bandwidth of the computing node and the bandwidth configuration parameters of each container.

[0091] Specifically, in one example, assuming that the preset duration is 100 ms (milliseconds), when the time interval between the current moment and the previous bandwidth allocation moment reaches 100 ms, the acquisition of the network bandwidth of the computing node and the bandwidth configuration parameters of each container in the computing node is executed, and then based on the acquired network bandwidth and the bandwidth configuration parameters of each container, the bandwidth is allocated to each container respectively.

[0092] In another example, when it is detected that the network of the computing node is in a congested state, that is, data loss or increased network queue delay occurs, or when it is detected that the bandwidth configuration of the container has changed, the acquisition of the network bandwidth of the computing node and the bandwidth configuration parameters of each container in the computing node is performed, and then based on the acquired network bandwidth and the bandwidth configuration parameters of each container, the bandwidth is allocated to each container.

[0093] Steps S802-S804 in the embodiment of the present application have been clearly explained in the previous text and will not be repeated here.

[0094] In one or more embodiments, Fig. 9 As shown, the embodiment of the present application also provides a reverse bandwidth allocation method, comprising the following steps:

[0095] S902, obtaining the network bandwidth of the computing node and the bandwidth configuration parameters of each container in the computing node.

[0096] S904: When the sum of the guaranteed bandwidths of the containers is less than or equal to the network bandwidth of the computing node, obtain a current bandwidth demand of a first container, where the first container is any container among the containers.

[0097] S906: Use a minimum value between the current demand and the guaranteed bandwidth of the first container as a first allocated bandwidth of the first container.

[0098] S908: Determine the maximum value of the first allocated bandwidth and the preset minimum allocated bandwidth of the first container as the used bandwidth of the first container. After step S908 is completed, execute step S910 or step S912.

[0099] S910: When the sum of the guaranteed bandwidths of the containers is greater than the network bandwidth of the computing node, display a prompt message indicating that the bandwidth configuration parameters of the containers are incorrect.

[0100] S912: When the sum of the guaranteed bandwidths of the containers is greater than the network bandwidth of the computing node, obtain the current bandwidth demand of the first container; use the minimum value of the current demand and the guaranteed bandwidth of the first container as the first allocated bandwidth of the first container; and when it is determined that the sum of the first allocated bandwidths of the containers is less than or equal to the network bandwidth of the computing node, allocate the used bandwidths of the containers to the containers respectively.

[0101] Specifically, the embodiments of the present application include but are not limited to processing abnormal data through an abnormal input processing module. For example, when the sum of the guaranteed bandwidths of each container is greater than the network bandwidth of the computing node, that is, the network bandwidth of the current computing node cannot guarantee the guaranteed bandwidth of its previous container in real time, a prompt message indicating that the bandwidth configuration parameters of each container are incorrect is displayed.

[0102] In one example, if the sum of the guaranteed bandwidths of the containers is greater than the network bandwidth of the computing node, the operation of allocating bandwidth usage to the containers can be performed according to the steps in the above embodiment to obtain the bandwidth usage of each container. It should be noted that the bandwidth usage of each container can be allocated to each container only when it is determined that the sum of the first allocated bandwidths of the containers is less than or equal to the network bandwidth of the computing node.

[0103] Steps S902-S908 in the embodiment of the present application have been clearly explained in the previous text and will not be repeated here.

[0104] Based on the above embodiment, as an optional implementation method, Fig.10 As shown, the embodiment of the present application also provides a data processing method, comprising the following steps:

[0105] 1) Bandwidth input parameter verification

[0106] The input parameter verification module calculates whether the sum of the guaranteed bandwidth (request) of each container is less than the available bandwidth of the computing node. If it is greater than the available bandwidth of the computing node, the bandwidth allocation of each container cannot always ensure that the configuration of the guaranteed bandwidth is met, and then enters the abnormal input processing module.

[0107] If the optional parameter reserved (reserved bandwidth of the computing node) is configured with a value, the corresponding reserved bandwidth of the computing node will not participate in the bandwidth allocation.

[0108] If the optional parameter minGuarantee (preset minimum allocated bandwidth) is configured with a value, determine the maximum value of the sum of the guaranteed bandwidth of each container and the sum of the preset minimum allocated bandwidth of each container, and calculate whether the maximum value is greater than the network bandwidth of the computing node through the input parameter verification module. If it is greater than the network bandwidth of the computing node, the bandwidth allocation of the container cannot guarantee that the bandwidth demand of the container is always met. At this time, the system's abnormal input processing module can be entered for processing.

[0109] 2) Phase I Bandwidth Allocation

[0110] During the bandwidth allocation in Phase I, when allocating the network bandwidth of the computing node to meet the real-time bandwidth requirements of the container, the minimum value between the current demand of each container and the guaranteed bandwidth of each container is used as the first allocated bandwidth of each container, and the first allocated bandwidth is determined as the used bandwidth of the container. After the allocation in this phase is completed, the remaining bandwidth to be allocated is the network bandwidth of the computing node minus the sum of the first allocated bandwidth of each container. It can be expressed as: rest_I = cap-∑allocate_I, where rest_I represents the remaining unallocated bandwidth of the computing node after the phase-I bandwidth allocation is completed, and cap represents the network bandwidth of the computing node.

[0111] Σallocate_I represents the sum of the first allocated bandwidths of each container.

[0112] If the optional parameter minGuarnatee is configured, the bandwidth allocated to the container in this phase must meet the following requirements: the maximum value between the above minimum value and minGuarnatee is used as the bandwidth used by the container.

[0113] 3) Phase II Bandwidth Allocation

[0114] Phase II complex allocation computes the unallocated bandwidth of the nodes in Phase I to meet the burst bandwidth requirements of each container. The embodiment of the present invention uses the maximum-min fairness algorithm (MMF) to allocate this part of the unallocated bandwidth. At the same time, the bandwidth allocated to the container in this phase should not exceed the burst bandwidth (maximum quota bandwidth) of the container. Therefore, the bandwidth allocated to each container in this phase is allocate_II i =MMF(rest_I,min(demand i , limit i ))-allocate_I i ). Where i is the number of the container, demand i is the current bandwidth requirement of container i, limit i is the burst bandwidth of container i, and the remaining bandwidth to be allocated is rest_II=cap-∑allocate_II.

[0115] 4) Phase III Bandwidth Allocation

[0116] Phase III is responsible for allocating the remaining bandwidth after the bandwidth allocation of computing nodes in Phase II. Before the allocation in this phase, if the allocation result has met the real-time bandwidth requirements of each container, during the allocation process in this phase, you can choose to keep this part of the bandwidth and not participate in the bandwidth allocation of the container; or allocate this part of the bandwidth evenly to each container; or use request (guaranteed bandwidth of the container) or limit (burst bandwidth of the container) as the weight, and allocate the remaining bandwidth of the computing node to each container based on the weight of each container.

[0117] The final bandwidth allocation result of each container is the sum of the bandwidth allocated in the three stages, that is, allocate_ i =allocate_I i +allocate_II i +allocate_III i .

[0118] 5) Abnormal input processing

[0119] When the sum of the guaranteed bandwidths of the containers is greater than the network bandwidth of the computing node, a prompt message indicating that the bandwidth configuration parameters of the containers are incorrect is displayed; or, if the sum of the guaranteed bandwidths of the containers is greater than the network bandwidth of the computing node, the operation of allocating bandwidth usage to the containers can be performed according to the steps in the above embodiment to obtain the bandwidth usage of each container. It should be noted that only when it is determined that the sum of the first allocated bandwidths of the containers is less than or equal to the network bandwidth of the computing node can the bandwidth usage of the containers be allocated to the containers respectively, and the output result of this embodiment is an executable node bandwidth allocation plan.

[0120] The above technical solution of the present application has the following beneficial technical effects:

[0121] 1. The embodiments of the present application not only have the ability to adjust the bandwidth allocation of the network in real time and dynamically, but also can provide the container with the ability to configure burst bandwidth.

[0122] 2. The embodiment of the present application implements a node bandwidth allocation method at a single container granularity, and can also quantitatively control bandwidth allocation.
