Description

[Technical field]

[0001] The present disclosure relates to the field of computer technology, and in particular to a method, device, apparatus and medium for cross-card link aggregation of a DPU virtual port. [Background technology]

[0002] Data Processing Unit (DPU) is a next-generation computing chip that is data-centric, I / O-intensive, and adopts the software-defined technology path to support the virtualization of infrastructure resource layer, improve computing system efficiency, reduce the total cost of ownership of the entire system, improve data processing performance, and reduce the performance loss of other computing chips.

[0003] Currently, the DPU card divides one physical port (MAC port) into multiple virtual ports (Virtual Functions, VFs) for use by virtual machines (VMs) running on the host machine. Each VF has a corresponding virtual port proxy (Virtual Function representor, VF rep), forming a (VF, VF rep) set, and the VF rep is used to send messages to the virtual switch (Open vSwitch, OVS). The MAC port also has a corresponding uplink port (uplink), forming a (MAC, uplink) set, and the uplink is also used to send messages to the OVS. The OVS processes and distributes the messages that pass through.

[0021] In order to make the above objectives, features and advantages of the present disclosure more clearly comprehensible, the technical solutions of the present disclosure are further described below. It should be noted that the embodiments and features in the embodiments of the present disclosure may be combined with each other without contradiction.

[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure. However, the present disclosure may be practiced in ways other than those described herein. It is apparent that the embodiments in the specification are only some of the embodiments of the present disclosure, not all of them.

[0023] The data processor is centered around data, is I / O intensive, adopts a software-defined technology path, supports the virtualization of the infrastructure resource layer, improves the computing system efficiency, reduces the total cost of ownership of the entire system, improves the data processing performance, and reduces the performance loss of other computing chips. It is equipped with a next-generation computing chip.

[0024] Currently, the DPU card divides one physical port (MAC port) into multiple virtual ports (Virtual Function, VF) for use by virtual machines (VM) running on the host machine. Each VF has a corresponding virtual port proxy (Virtual Function representor, VF rep), forming a (VF, VF rep) set. The VF rep is used to send messages to the virtual switch (Openv Switch, OVS). The MAC port also has a corresponding uplink port, forming a (MAC, uplink) set. The uplink is also used to send messages to the OVS. The OVS processes and distributes the passed messages.

[0025] In the prior art, there is only one DPU card, and the VFs on each VM belong to one DPU card. Since all the traffic of the VFs needs to pass through the DPU card, there is a problem of single point of failure. Once a hardware failure occurs in the DPU card, the network will be disconnected and high availability cannot be guaranteed. In response to this problem, the embodiments of the present disclosure provide a cross-card link aggregation method for DPU virtual ports, and this method will be described below in connection with specific embodiments.

[0026] 1 is a flow chart of a method for cross-card link aggregation of a DPU virtual port provided by an embodiment of the present disclosure, the method can be applied to electronic devices such as computers, notebook computers, etc., the method can be applied to the scenario of message communication based on multiple data processors, and the problem of network interruption caused by single point failure can be avoided, so as to ensure high availability. It should be understood that the method for cross-card link aggregation of a DPU virtual port provided by an embodiment of the present disclosure can also be applied to other scenarios.

[0027] Next, referring to FIG. 2, a cross-card link aggregation method of the DPU virtual port shown in FIG. 1 is introduced, which includes the following steps:

[0028] S101, each of which performs link negotiation with a virtual machine and a switch.

[0029] In some alternative embodiments, at least two data processors are disposed in the electronic device, and each data processor is communicatively connected between the virtual machine and the switch. By using the VF passage through the two DPU cards for the VM, a logical (bond) port is formed inside the VM, and at the same time, the physical port links on the two DPU cards are aggregated to jointly transmit and receive network traffic. In this step, as shown in FIG. 2, the electronic device performs link negotiation for the virtual machine and the switch, respectively, that is, performs dynamic negotiation for the bond between the DPU and the VM, or the bond between the DPU and the switch. For example, the negotiation is performed by sending a negotiation message and feeding back the negotiation message. After the negotiation, the switch can send a data message through two paths, and the VM can receive a data message through two paths. Similarly, a message from the VM also reaches the switch through two paths.

[0030] The aggregation of multiple network ports, i.e. link aggregation, forms a logical port (bond port), which realizes load balancing of inbound / outbound traffic throughput at each member port. If a failure is detected in the link of one of the member ports, the port stops sending messages and recalculates the sending port of messages to the remaining links according to the load balancing policy. After the failed port is restored, it takes over the sending and receiving ports again. Link aggregation can increase link bandwidth, link redundancy, etc.

[0031] S102, obtaining a data message to be communicated, the data message to be communicated including a target side identifier, a source side identifier and a message type.

[0032] The electronic device obtains a data message to be communicated, and the data message to be communicated includes a target side identifier, a source side identifier, and a message type. The data message to be communicated may be from the switch and sent to the virtual machine, or may be from the virtual machine and sent to the switch. The data message to be communicated includes a target side identifier, a source side identifier, and a message type. The message type is divided into a negotiation message, a data message, etc. The source side identifier represents an identifier of a sender of the data message to be communicated, and the target side identifier represents an identifier of a receiver of the data message to be communicated.

[0033] S103: determining a communication link for the data message to be communicated, the communication link being a virtual port on a virtual machine, a virtual port proxy corresponding to the virtual port on the virtual machine, an uplink port corresponding to a physical port on a data processor, a physical port on the data processor, and a message path between the switches.

[0034] At least two data processors are arranged in the electronic device, each data processor is connected to a virtual machine and a switch, and the paths for multiple VFs in a VM to send and receive messages belong to different DPU cards, forming multiple links. In this embodiment, the electronic device determines the communication link of the data message to be communicated. The communication link is a message path between a virtual port on the virtual machine, a virtual port proxy corresponding to the virtual port on the virtual machine, an uplink port corresponding to a physical port on the data processor, a physical port on the data processor, and a switch. As shown in FIG. 5, the message path is bidirectional, that is, a data message can be transmitted from a virtual port on a virtual machine to a virtual port proxy corresponding to a virtual port on a virtual machine, to an uplink port corresponding to a physical port on the data processor, to a physical port on the data processor, and finally to the switch, and a data message can be transmitted from the switch to a physical port on the data processor, an uplink port corresponding to a physical port on the data processor, to a virtual port proxy corresponding to a virtual port on a virtual machine, and finally to a virtual port on a virtual machine.

[0035] S104, communicating the data message to be communicated over the communication link.

[0036] In this embodiment, the electronic device communicates the data message to be communicated based on the communication link. At least two data processors are arranged in the electronic device, and each data processor is communicatively connected to a virtual machine and a switch, and the paths through which multiple VFs in a VM send and receive messages belong to different DPU cards, forming multiple links. Messages can be communicated through multiple communication links, thereby solving the problem of single point failure that exists in the prior art.

[0037] In some embodiments, a user can configure a virtual port on a virtual machine to be load balanced, and the virtual machine balances and sends the load across multiple VFs according to the load balancing configuration. In some embodiments, a user can configure traffic for a virtual port on a virtual machine, and the virtual machine balances and sends the traffic across multiple VFs based on the traffic configuration.

[0038] In some embodiments, a user can configure a network port on a switch for load balancing, and the switch balances and sends the load across multiple VFs according to the load balancing configuration. In some embodiments, a user configures traffic for a network port on a switch, and the switch balances and sends the traffic across multiple VFs according to the traffic configuration.

[0039] In the embodiment of the present disclosure, by installing multiple data processors, each data processor is communicatively connected between a virtual machine and a switch, and each performs link negotiation with the virtual machine and the switch to obtain a data message to be communicated, the data message to be communicated includes a target side identifier, a source side identifier, and a message type, and a communication link for the data message to be communicated is determined, the communication link is a virtual port on the virtual machine, a virtual port proxy corresponding to the virtual port on the virtual machine, an uplink port corresponding to a physical port on the data processor, a physical port on the data processor, and a message passage between the switch, and the data message to be communicated is communicated through the communication link. Since multiple data processors are installed and each data processor is communicatively connected between the virtual machine and the switch, a message can be communicated through multiple communication links, and the problem of network interruption caused by a single point of failure can be avoided, thereby ensuring high availability.
