Background Art

[0002] With the development of virtualization technology, multiple virtual machines can be deployed on one server. Moreover, the system configuration information of different virtual machines may be different, and the number of virtual containers included may also be different. In order to improve the flexibility of the system configuration information of virtual machines, the number of virtual containers in the virtual machines can be further adjusted.

[0003] In the prior art, a container control assembly can be installed in a virtual machine, and a container operation instruction can be sent to the container control assembly.

[0004] However, the inventor has discovered that the prior art has at least the following technical problems. For each virtual machine, the container operation instructions sent to the container control assembly in the virtual machine all occupy the CPU resources of the server. Therefore, when there are many container operation instructions, the consumption of CPU resources increases, the speed at which the server transmits container operation instructions decreases, and the data transmission efficiency becomes low.

[Figure 6] Figure 6 is a schematic diagram of the hardware structure of an electronic device provided in an embodiment of this disclosure. [Modes for carrying out the invention]

[0013] To clarify the purpose, technical solutions and advantages of the embodiments of this disclosure, the technical solutions of the embodiments of this disclosure will be described clearly and completely below with reference to the drawings of the embodiments of this disclosure. It will be obvious that the embodiments described are not all embodiments, but only some embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without requiring any creative work are all within the scope of this disclosure.

[0014] Furthermore, the user information (including, but not limited to, the user's device information and personal information) and data (including, but not limited to, data for analysis, stored data, displayed data, etc.) relating to this application are all information and data authorized by the user or fully authorized by each party, and the collection, use, and processing of the relevant data must comply with applicable laws, regulations, and standards, and corresponding operational entries must be provided for the user to choose to authorize or deny.

[0015] With advancements in virtualization technology, it is possible to deploy multiple virtual machines on a single server. Furthermore, the system configuration information of different virtual machines may differ, and the number of virtual containers they contain may also differ. To further improve the flexibility of the system configuration information of virtual machines, the number of virtual containers within a virtual machine can be adjusted.

[0016] In the prior art, a container control assembly can be installed in a virtual machine, and container operation instructions can be sent to the container control assembly. The container control assembly receives and executes the container operation instructions to complete the adjustment of the number of containers in the virtual machine. However, for each virtual machine, all the container operation instructions sent to the container control assembly in the virtual machine occupy the CPU (Central Processing Unit) resources of the server. Therefore, when there are many container operation instructions, the consumption of CPU resources increases, the speed at which the server transmits container operation instructions decreases, and the data transmission efficiency becomes low.

[0017] As can be seen from the above, how to reduce the consumption of CPU resources and improve the data transmission efficiency is an urgent problem to be solved currently.

[0018] In the prior art, the control instruction assembly for generating container control instructions is deployed on the CPU of the server. Therefore, in the process of generating container control instructions by the control instruction assembly, it occupies CPU resources, increasing the consumption of CPU resources. In addition, the control instruction assembly further needs to transmit the container control instructions to the container control assembly and execute the container control instructions through the container control assembly. Here, since the transmission process of the container control instructions also occupies CPU resources, the consumption of CPU resources further increases.

[0019] To reduce the consumption of CPU resources, a DPU (Data Processing Unit) is deployed in the cloud service system, and some applications on the virtual machine are offloaded to the DPU, so as to reduce the consumption of the CPU of the server, improve the utilization efficiency of the server, reduce the energy consumption of the server, and bring more cost benefits to cloud service providers.

[0020] In an embodiment of the present disclosure, control instruction assemblies of a plurality of virtual containers (applications on the original virtual machine) can be offloaded to the DPU and become applications on the DPU after offloading. After offloading, since it is necessary to transmit the container control instructions generated by the control instruction assembly from the DPU to the virtual machine, it is necessary to establish communication between the virtual machine and the DPU.

[0021] Before offloading (i.e., in a non-DPU scenario), since all instruction transfer operations between different assemblies are completed in the same operating system on the same physical machine, mutual communication can be directly performed through the interface provided by the operating system.

[0022] However, after offloading (i.e., in a DPU scenario), due to the offloading method, the original execution environment of the same type of operating system is divided into environments of different heterogeneous operating systems, and at this time, direct communication through the interface provided by the operating system is not possible. Therefore, after offloading the control instruction assembly to the DPU, how to establish communication between the virtual machine and the DPU is a technical problem that must be solved.

[0023] To solve the above problems, this embodiment further provides the following technical concept: A control instruction assembly and a communication assembly are installed in a DPU (Data Processing Unit), and communication between the virtual machine and the DPU is established via the communication assembly. The specific steps may include first, the control instruction assembly in the DPU receives a configuration request for at least one virtual container, generates a container operation instruction corresponding to the configuration request via the control instruction assembly, and sends the container operation instruction to the communication assembly in the DPU; second, the communication assembly in the DPU converts the container operation instruction into communication data conforming to the communication protocol corresponding to the communication assembly, and transfers the converted communication data to the container control assembly in the virtual machine; and finally, the container control assembly determines a control operation corresponding to the communication data and executes the control operation for at least one virtual container.

[0024] By installing control instruction assemblies and communication assemblies within the DPU, container operation instructions can be generated via the control instruction assembly and sent to virtual machines via the communication assembly. Furthermore, since the control instruction assembly and communication assembly are installed within the DPU and do not occupy CPU resources within the server, they are not affected by CPU consumption, thereby improving data transmission efficiency.

[0025] The following interpretations describe the application scenarios of the embodiments of this disclosure.

[0026] The data transmission method provided in the embodiments of this disclosure can be applied to data transmission scenarios between a server and a DPU in a cloud service system. The information between the server and the DPU may be container operation instructions for multiple containers in a virtual machine deployed on the server. Figure 1 is a schematic diagram of the structure of a cloud service system provided in the embodiments of this disclosure. As shown in Figure 1, the cloud service system includes a server 101 and a data processing unit DPU 102. A virtual machine containing a container control assembly and multiple virtual containers is deployed on the server 101. A control instruction assembly is installed on the DPU 102, and the control instruction assembly can generate container control instructions for at least one virtual container. After receiving a container control instruction, the container control assembly on the virtual machine deployed on the server 101 can adjust the number of at least one virtual container based on the container control instruction. During the execution of a container control instruction, it is necessary to establish communication between the DPU 102 and the server 101 and transmit the container control instruction generated by the control instruction assembly on the DPU 102 to the container control assembly on the virtual machine deployed on the server 101. To reduce the resource consumption of server 101, this invention proposes deploying a communication assembly on DPU 102 and establishing communication between DPU 102 and server 101 using the communication assembly on DPU 102. In this way, the transmission process of container control instructions is not affected by the server's CPU consumption, thereby improving the transmission efficiency of information (i.e., container control instructions). The data transmission method provided by the embodiments of this disclosure will be described in detail below using detailed embodiments.

[0027] Figure 2 is a flowchart of a data transmission method provided in an embodiment of the present disclosure. The data transmission method can be applied to a cloud service system including a server and a data processing unit (DPU), wherein a virtual machine containing a container control assembly and multiple virtual containers is deployed on the server. As shown in Figure 2, the method includes S201, S202, and S203.

[0028] S201, in response to the control instruction assembly in the DPU receiving a configuration request for at least one virtual container, generates a container operation instruction corresponding to the configuration request via the control instruction assembly and transmits the container operation instruction to the communication assembly in the DPU.

[0029] In embodiments of this disclosure, a virtual container configuration request may be a request to adjust the number of virtual containers, or a request to adjust the configuration information of a virtual container. In some embodiments, a virtual container configuration request may be a configuration request to increase the number of multiple virtual containers in a virtual machine, or a configuration request to decrease the number of multiple virtual containers in a virtual machine. In other embodiments, a virtual container configuration request may be a request to increase the execution memory of a virtual container, or a request to decrease the execution memory of a virtual container.

[0030] Selectively, the server can generate a configuration request for at least one virtual container and send the configuration request to the control instruction assembly in the DPU. In some embodiments, the generation of a configuration request may be triggered by a user using the virtual machine. For example, if a user needs to adjust the system configuration of a virtual machine, they can send an adjustment request to the server, which generates a configuration request and sends it to the control instruction assembly in the DPU. For example, if a user increases the number of virtual containers in service A via a terminal, the terminal can send an adjustment request to the server, which generates a configuration request to increase the number of virtual containers.

[0031] In another embodiment, the generation of configuration requests may be automatically triggered by the server. For example, if the number of requests processed by a virtual machine increases, the execution load on the virtual machine increases, and at this time, the server can automatically trigger the generation of a configuration request to increase the number of virtual containers. Alternatively, if the number of requests processed by a virtual machine decreases, the execution load on the virtual machine decreases, and at this time, the server can automatically trigger the generation of a configuration request to decrease the number of virtual containers.

[0032] Selectively, a control instruction assembly within the DPU may be a control plane assembly for at least one virtual container. Exemplarily, the control plane assembly may be a containerd assembly, and container operation instructions for at least one virtual container can be generated via the containerd assembly.

[0033] In the embodiments of this disclosure, the communication assembly within the DPU may be a communication assembly conforming to any communication protocol. Selectively, the communication assembly may take the form of a communication assembly conforming to the virtio-vsock communication protocol, a communication assembly conforming to the IP communication protocol, or a communication assembly conforming to the TCP communication protocol.

[0034] Furthermore, the communication assembly of the virtio-vsock communication protocol provides a socket operation interface to user applications (e.g., the containerd assembly), and can complete the interaction between the virtual machine and the host via the virito protocol. Compared to communication protocols such as TCP / IP, the virito protocol simplifies the contents of the protocol stack and the difficulty of implementation, improving the communication efficiency between the virtual machine and the host.

[0035] Here, both the control instruction assembly and the communication assembly are offloaded to the DPU, allowing the heterogeneous computing capabilities of the new DPU hardware to be fully utilized, thereby reducing the server's CPU consumption.

[0036] S202 converts container operation commands via the communication assembly into communication data that conforms to the communication protocol corresponding to the communication assembly, and then transfers the communication data to the container control assembly within the virtual machine.

[0037] In embodiments of the present disclosure, a communication protocol can be determined via interface information corresponding to a communication assembly. Accordingly, the step of converting a container operation command via a communication assembly into communication data conforming to the communication protocol corresponding to the communication assembly includes the steps of obtaining interface information corresponding to the communication assembly, determining a communication protocol corresponding to the interface information, and converting a container operation command via a communication assembly into communication data conforming to the communication protocol.

[0038] Selectively, the communication assembly is a vsock-user assembly conforming to the virtio-vsock communication protocol. Accordingly, the steps of obtaining interface information corresponding to the communication assembly and determining the communication protocol corresponding to the interface information include obtaining the interface information corresponding to the vsock-user assembly as a Unix socket interface, and determining, based on the Unix socket interface and the correspondence between the stored interface information and the communication protocol, that the communication protocol corresponding to the Unix socket interface is the virtio-vsock communication protocol.

[0039] In embodiments of this disclosure, communication data can be transferred to a container control assembly within a virtual machine via a DMA (Direct Memory Access) driver. The DMA driver corresponds to a network cable that transmits communication data. Selectively, as shown in Figure 3, a direct memory access DMA driver backend is installed on the DPU, and a DMA driver frontend that transmits data with the DMA driver backend is installed on the server. Accordingly, the step of transferring communication data to a container control assembly within a virtual machine includes the steps of: transmitting the communication data to the DMA driver backend via the communication assembly; responding to the completion of the transmission of the communication data, sending a transmission completion command to the DMA driver backend via the communication assembly; the DMA driver backend responding to receiving the transmission completion command, transmitting the communication data to the DMA driver frontend via the DMA driver backend; and transferring the communication data to a container control assembly within a virtual machine via the DMA driver frontend. Exemplarily, as shown in Figure 3, the communication assembly is a vsock-user assembly. A virtual container can be represented by a container. A container control assembly can be represented by a kata-agent.

[0040] In this process, the communication assembly (e.g., the vsock-user assembly) can be executed on the DPU as a separate process. It receives container operation instructions sent by the control instruction assembly and converts these instructions into communication data that conforms to the communication protocol corresponding to the communication assembly. Furthermore, by sending a transmission completion instruction to the DMA driver backend, it can operate the DMA driver backend, transmit the communication data to the DMA driver frontend, and enable reading, writing, and copying of the communication data.

[0041] S203 determines a control operation corresponding to the communication data via the container control assembly and executes the control operation for at least one virtual container.

[0042] In the embodiments of this disclosure, it is necessary to analyze communication data via a container control assembly in order to determine the specific operation content of a container operation command. Accordingly, this step includes analyzing communication data via a container control assembly to obtain container coordination information corresponding to a container operation command, determining a control operation corresponding to the container coordination information, and executing the control operation corresponding to the container coordination information for at least one virtual container.

[0043] Selectively, container adjustment information includes one or more of the following: an increase in the number of virtual containers, a decrease in the number of virtual containers, an increase in the execution memory of at least one virtual container, a decrease in the execution memory of at least one virtual container, an increase in the storage space of at least one virtual container, or a decrease in the storage space of at least one virtual container. Of these, the container adjustment information may also include further adjusted numerical information.

[0044] For example, the container adjustment information corresponding to a container operation command is an increase in the number of virtual containers, with an increase of 1, and accordingly, the control operation corresponding to the container adjustment information is to increase the number of virtual containers by 1.

[0045] For example, the container adjustment information corresponding to a container operation command is a decrease in the number of virtual containers, with a decrease of 2. Accordingly, the control operation corresponding to the container adjustment information is to reduce 2 virtual containers.

[0046] The data transmission method provided by this embodiment is as follows: A control instruction assembly in the DPU receives a configuration request for at least one virtual container, generates a container operation instruction corresponding to the configuration request via the control instruction assembly, and sends the container operation instruction to a communication assembly in the DPU. The communication assembly converts the container operation instruction into communication data conforming to the communication protocol corresponding to the communication assembly, and transfers the communication data to a container control assembly in the virtual machine. The container control assembly determines the control operation corresponding to the communication data and executes the control operation for at least one virtual container. In this embodiment, a control instruction assembly and a communication assembly are installed in the DPU, a container operation instruction can be generated via the control instruction assembly, and the container operation instruction can be sent to the virtual machine via the communication assembly. Furthermore, because the control instruction assembly and the communication assembly are installed in the DPU, they do not occupy CPU resources in the server, data transmission is not affected by CPU consumption, and thus data transmission efficiency can be improved.

[0047] In one embodiment of the present disclosure, the first operating system installed on the DPU and the second operating system installed on the server may be different, thereby enabling the offloading of both the control instruction assembly and the communication assembly to the DPU. Accordingly, as shown in Figure 4, the step of installing the first operating system on the DPU and installing the installation package corresponding to the communication assembly in the first operating system is included in step S401 prior to the step of sending the container operation instruction to the communication assembly in the DPU.

[0048] Furthermore, interface information corresponding to a communication assembly can be set as fixed interface information for which changes to the interface attributes are prohibited. For example, if the communication assembly is a vsock-user assembly, and the interface information corresponding to this communication assembly is a Unix socket interface, then the Unix socket interface can be set as a fixed interface for which changes to the interface attributes are prohibited.

[0049] In the embodiments of this disclosure, by setting the interface information corresponding to the communication assembly as fixed interface information, the stability of the user interface can be maintained, thereby further improving the data transmission efficiency.

The data transmission device is applied to a cloud service system including a server and a data processing unit (DPU), the server being deployed with a virtual machine including a container control assembly and a plurality of virtual containers, and the device including a generation module 501, a conversion module 502 and an execution module 503.

[0051] According to one or more embodiments of the present disclosure, the steps by which the conversion module 502 converts the container operation command via the communication assembly into communication data conforming to a communication protocol corresponding to the communication assembly include, specifically, the steps of: obtaining interface information corresponding to the communication assembly and determining a communication protocol corresponding to the interface information; and converting the container operation command via the communication assembly into communication data conforming to the communication protocol.

[0052] According to one or more embodiments of the present disclosure, the communication assembly is a vsock-user assembly conforming to the virtio-vsock communication protocol, and accordingly, the steps of the conversion module 502 to acquire interface information corresponding to the communication assembly and determine the communication protocol corresponding to the interface information specifically include the steps of acquiring the interface information corresponding to the vsock-user assembly as a Unix socket interface, and determining, based on the Unix socket interface and the correspondence between the stored interface information and the communication protocol, that the communication protocol corresponding to the Unix socket interface is the virtio-vsock communication protocol.

[0053] According to one or more embodiments of the present disclosure, a memory access DMA driver backend is installed directly on the DPU, and a DMA driver frontend is installed on the server to transmit data with the DMA driver backend. Accordingly, the steps of the conversion module 502 transferring the communication data to a container control assembly in the virtual machine include, specifically, transmitting the communication data to the DMA driver backend via the communication assembly, responding to the completion of the transmission of the communication data by sending a transmission completion command to the DMA driver backend via the communication assembly, and the DMA driver backend responding to receiving the transmission completion command by transmitting the communication data to the DMA driver frontend via the DMA driver backend, and transferring the communication data to a container control assembly in the virtual machine via the DMA driver frontend.

[0054] According to one or more embodiments of the present disclosure, the steps of the execution module 503 determining a control operation corresponding to the communication data via the container control assembly and executing the control operation on at least one virtual container include, specifically, the steps of analyzing the communication data via the container control assembly to obtain container adjustment information corresponding to the container operation command, and determining a control operation corresponding to the container adjustment information and executing the control operation corresponding to the container adjustment information on at least one virtual container, wherein the container adjustment information includes one or more of the following: an increase in the number of virtual containers, a decrease in the number of virtual containers, an increase in the execution memory of at least one virtual container, a decrease in the execution memory of at least one virtual container, an increase in the storage space of at least one virtual container, and a decrease in the storage space of at least one virtual container.

[0055] According to one or more embodiments of the present disclosure, the first operating system installed on the DPU differs from the second operating system installed on the server, and accordingly, the device further includes an installation module for installing the first operating system on the DPU and installing an installation package corresponding to the communication assembly on the first operating system.
