Description

Background Art

[0002] With the rapid development of technologies such as cloud computing and big data, the growth of network traffic and the increasing complexity of network management have made it difficult for traditional network architectures to meet the needs of modern data centers and cloud computing scenarios. In order to meet this challenge, software-defined network architectures have emerged. Software-defined network architectures achieve centralized and programmable control of network resources by separating the control plane and the data plane. However, traditional software-layer traffic processing methods based on the host CPU will impose a heavy burden on the system when processing large-scale network traffic, leading to performance bottlenecks.

[0003] In the related technologies, RISC-V is an emerging instruction set architecture. Through custom RISC-V instruction set extensions, chip manufacturers can customize chip functions according to the needs of specific application scenarios, thereby improving chip performance and efficiency. However, the current instruction set extensions for RISC-V are mainly concentrated in the fields of integer operations, floating-point operations, bit operations, vector operations, dynamic language translation, virtualization, etc. There is a lack of custom RISC-V instruction set extensions for network applications. Complex software logic is required to achieve network communication. When these operations are executed at the software level, they will occupy a large amount of CPU resources, resulting in increased data processing delays.

[0052] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0053] Figure 1 FIG. 1 shows an exemplary application system architecture diagram to which the data processing method in the embodiment of the present disclosure can be applied. Figure 1 As shown, the system architecture may include an OVS multi-layer virtual switch 101, a RISC-V system 102, and a server Host 103.

[0054] Among them, OVS includes the ows-ofctl command line tool for remote operation (Remote), which uses the ovs-ofctl command to add flow table entries, delete flow table entries, view flow tables, and modify flow table entries; User space (User space) of ovs-dpctl (kernel module datapath for configuring and managing OVS), ovs-appctl (used to interact with applications running on OVS switches, which can send control commands or obtain diagnostic information), ovs-vsctl (configure and manage OVS switches), ovs-tool (a tool for processing OVS databases, which can be used to check database structure, backup or restore databases), ovs-client (a command line tool that performs query or update operations), ovs-vswitchd (vswitchd, the core switch process of OVS, is responsible for processing data packet forwarding and traffic management), ovsdb-server (the database server of OVS, which stores all network configuration information, including ports, bridges, flow tables and OpenFlow rules of virtual switches, and provides OVSDB operation interfaces for controllers and ovs-vswitchd), ovsdb (a database of various configuration information stored in open virtual switches, which is a lightweight database developed for Open vSwitch); Kernel space (Kernel space) of ovs-dpctl (kernel module datapath for configuring and managing OVS), ovs-appctl (used to interact with applications running on OVS switches, which can send control commands or obtain diagnostic information), ovs-vsctl (configure and manage OVS switches), ovs-tool (a tool for processing OVS databases, which can be used to check database structure, backup or restore databases), ovs-client (a command line tool that performs query or update operations), ovs-vswitchd (vswitchd, the core switch process of OVS, is responsible for processing data packet forwarding and traffic management), ovsdb-server (the database server of OVS, which stores all network configuration information, including ports, bridges, flow tables and OpenFlow rules of virtual switches, and provides OVSDB operation interfaces for controllers and ovs-vswitchd), ovsdb (a database of various configuration information stored in open virtual switches, which is a lightweight database developed for Open vSwitch); space)'s openvswitch (the core module of datapath packet forwarding and processing functions), and ovs-vswitchd (the user-mode switch daemon) work together.

[0055] The RISC-V system includes Pcle Switch (PCIe switch), RDMA, flow table cache, packet processing and ports.

[0056] The server Host includes Driver and Socket.

[0057] In a specific example, in the OVS data plane accelerated network offload architecture after the OpenFlow flow table action instructions are customized with RISC-V instructions, after receiving the data flow, OVS will determine whether the current data flow rules can be offloaded to the network card. If so, the flow table rules will be sent to the hardware, and subsequent messages of the same data flow can be forwarded directly in the RISC-V system.

[0058] Figure 2 A flow chart of a data processing method in an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the data processing method provided in the embodiment of the present disclosure includes the following steps:

[0059] S202, the programmable network card obtains a data packet to be processed sent by the multi-layer virtual switch.

[0060] It should be noted that the above-mentioned programmable network card can be a hardware device with programmable logic, which can communicate directly with the host system and process and forward data packets during data transmission. For example, the above-mentioned programmable network card is an intelligent network card, which is used to process some tasks originally performed by the CPU, supports various virtualization functions, and adapts to the needs of software-defined network deployment. The above-mentioned multi-layer virtual switch can be a device that can provide multi-layer switching functions in a virtualized environment. For example, the above-mentioned multi-layer virtual switch is OVS, which supports virtualization environment and software-defined network technology. The above-mentioned data packets to be processed can be data packets waiting to be further processed or forwarded during network communication or data processing.

[0061] S204: The programmable network card performs a flow processing operation on the data packet to be processed.

[0062] It should be noted that the above stream processing may be a real-time data processing technology, that is, a method of continuously processing real-time incoming data.

[0063] S206, when the flow processing operation includes a preset extension instruction, the programmable network card accelerates the processing of the data packet to be processed according to the preset extension instruction and saves the processing result, wherein the preset extension instruction is oriented to the network application.

[0064] It should be noted that the above-mentioned preset extended instructions may be custom extended instructions, such as RISC-V instructions. The above-mentioned network-oriented applications may be specially designed for the needs of network applications.

[0065] S208, the programmable network card sends the processing result to the host.

[0066] It should be noted that the above host may be a server, for example, a server host in a cloud computing scenario.

[0067] This application optimizes the specific processing requirements of network data by extending instructions for network applications. The programmable network card uses these instructions to accelerate processing and feeds back the processing results to the host, thereby reducing the load on the host CPU and solving the problem of increased data processing delays caused by the lack of an instruction set for network applications.

[0068] In one embodiment of the present disclosure, Figure 3 As shown, the data processing method provided in the embodiment of the present disclosure further includes the following steps before obtaining the data packet to be processed sent by the multi-layer virtual switch:

[0069] S302, the multi-layer virtual switch obtains a data packet to be processed;

[0070] S304, the multi-layer virtual switch sends a flow table request to the open flow controller to obtain flow table information;

[0071] S306, the multi-layer virtual switch determines whether the programmable network card supports the flow entry action according to the flow table information;

[0072] S308, if the programmable network card supports the flow entry action, the multi-layer virtual switch sends the data packet to be processed to the programmable network card;

[0073] S310: If the programmable network card does not support the flow entry action, the multi-layer virtual switch performs flow processing on the data packet to be processed.

[0074] Through the collaborative work of a multi-layer virtual switch and an open flow controller, the present application can dynamically obtain flow table information and determine the processing method of data packets based on the flow table information. At the same time, when the programmable network card supports flow entry actions, the multi-layer virtual switch can directly send the data packets to be processed to the programmable network card, and use the hardware acceleration capability of the programmable network card to process the data packets, thereby improving the processing efficiency of the data packets.

[0075] In one embodiment of the present disclosure, Figure 4 As shown, the data processing method provided in the embodiment of the present disclosure further includes the following steps after the programmable network card performs a flow processing operation on the data packet to be processed:

[0077] S404, if yes, accelerating the processing of the data packet to be processed according to the preset extended instruction;

[0078] S406: If not, process the data packet to be processed according to the general instruction.

[0079] The present disclosure adopts different processing strategies according to whether the flow processing operation contains preset extension instructions through a programmable network card, so that the programmable network card can more accurately control the processing flow of data packets, reduce unnecessary resource consumption, and achieve an improvement in the data packet processing speed.

[0082] S504, when the stream processing operation is submitted to the programmable network card, the programmable network card traverses the preset extended instructions to determine whether the instructions in the stream processing operation exist in the preset extended instructions.

[0083] The present disclosure stores preset extended instructions in the programmable network card. When a stream processing operation is submitted, the network card can quickly traverse these preset instructions to determine whether the instructions in the stream processing operation exist. This fast matching mechanism reduces processing delays and improves the real-time processing capability of data packets.

[0133] In the SDN scenario, the present invention aims at accelerating the network offloading of the OVS data plane. By forwarding data packets in the RISC-V system, the data packet processing is offloaded to the hardware, which effectively reduces the load of the host CPU and further improves the network performance.

[0134] Fig. 9 The schematic diagram of the structure of the multi-layer virtual switch OVS data plane accelerating network offloading in the embodiment of the present disclosure is shown, including the hardware RISC-V system, kernel state and user state. In the specific implementation, the following process is included:

[0135] First packet processing: When the first data packet arrives at the RISC-V system, the RISC-V system queries the flow table cache based on the packet characteristics. If it hits, it is forwarded directly; if it does not hit, the data packet is reported to the OVS kernel state for processing.

[0136] Kernel state processing: If the OVS kernel state matches the flow table rule, the data packet is forwarded directly; if it does not match, the user state is notified through the netlink upcall mechanism for further processing;

[0137] User state processing: User state performs precise flow table and fuzzy flow table queries. If the fuzzy query hits, both the user state precise flow table and the kernel state precise flow table are refreshed; if the precise query hits, only the kernel state flow table is updated. At the same time, the user state will check whether the RISC-V system unloading is supported. If it is supported, the direct unloading of the flow table is completed.

[0138] Packet processing: After the flow table is refreshed, the packet is re-injected into the kernel datapath module for processing.

[0139] Flow table cache: Send flow table information to the RISC-V system for caching.

[0140] Subsequent message processing: Subsequent messages of the same data stream are directly forwarded through the RISC-V system.
