[0025] Figure 1A schematic diagram of a flow chart of a network communication method for a board-level management controller provided in an embodiment of the present application. Figure 1 As shown, the network communication method includes the following steps.

[0026] Step S101: providing a message copying module through a first network interface card, wherein the message copying module is used to copy an uplink message passing through the first Ethernet port and meeting a first matching condition to a first network port set when a first Ethernet port of the first network interface card is shared between a host machine and a board-level management controller, the first network port set including a network port of the host machine corresponding to the first Ethernet port and a network port of the board-level management controller corresponding to the first Ethernet port.

[0027] Step S103: A scheduling module is provided through the first network interface card, wherein the scheduling module is used to execute a downlink speed limit strategy for downlink traffic passing through the first Ethernet port, wherein the downlink speed limit strategy limits the maximum bandwidth and maximum burst bandwidth of the board-level management controller and limits the maximum bandwidth and maximum burst bandwidth of the host machine.

[0028] Step S105: using the message replication module and the scheduling module of the first network interface card, the first Ethernet port is shared between the host machine and the board management controller, and network communication between the board management controller and the simplified media independent interface of the first network interface card is achieved.

[0029] Figure 1The network communication method for the board management controller shown is applied to technical fields such as cloud computing, data centers, and artificial intelligence. Through the board management controller (Baseboard Management Controller, BMC), a unified access interface is provided to the outside, providing services such as temperature, voltage, fan, bus monitoring, etc., which can be used for remote management and remote login of the server. The external communication of the board management controller is carried out through the independent management network port integrated on the server board. By using the network controller sideband interface (Network Controller-Sideband Interface, NC-SI) technology, the board management controller and the reduced media independent interface (Reduced Media Independent Interface, RMII) on the board where the network interface card is located communicate with each other on the network, so that the board management controller can refer to the independent network card management method to manage the service network interface card on the motherboard. The reduced media independent interface generally has a maximum bandwidth, such as a network rate of 100 megabits per second. By using the saved independent network card position, other business cards can be used, thereby increasing the density of the server and providing richer functions and services. If the board-level management controller is arranged to exclusively use the Ethernet port on the network interface card for external communication, this will help isolate services and avoid resource conflicts, but it will occupy the limited Ethernet port resources on the network interface card, and the bandwidth of the network interface card as a service interface can be used to provide rich functions, which is not conducive to cost control. In order to achieve service isolation and avoid resource conflicts, as well as to avoid insufficient service bandwidth resources, Figure 1 The network communication method for the board-level management controller shown in the figure, on the basis of arranging the Ethernet port on the network interface card shared between the board-level management controller and the host, optimizes the network interface card at the software level and the hardware level, and then improves the uplink message processing flow and the downlink message processing flow, which not only realizes the sharing of the Ethernet port between the board-level management controller and the host, but also ensures the isolation of services, avoids resource conflicts, ensures the bandwidth resources of the board-level management controller, is conducive to improving the server density, provides richer functions and services, and is conducive to reducing costs and improving resource utilization. The following is a detailed description.

[0030] refer to Figure 1In step S101, a message copy module is provided through the first network interface card. The message copy module is used to copy the uplink message passing through the first Ethernet port and meeting the first matching condition to the first network port set when the first Ethernet port of the first network interface card is shared between the host machine and the board-level management controller, and the first network port set includes the network port of the host machine corresponding to the first Ethernet port and the network port of the board-level management controller corresponding to the first Ethernet port. Here, the message copy module is provided through the optimization of the software level and the hardware level of the first network interface card, and the message copy module is used to copy the uplink message passing through the first Ethernet port and meeting the first matching condition to the first network port set when the first Ethernet port of the first network interface card is shared between the host machine and the board-level management controller. In this way, the first Ethernet port of the first network interface card can be shared between the host machine and the board-level management controller, and when the first Ethernet port of the first network interface card as a service interface receives specific uplink messages, the destination of these specific uplink messages may be the host machine or the board-level management controller. In order to ensure the correct forwarding of messages, when the first Ethernet port of the first network interface card is shared between the host machine and the board-level management controller, a message copy module is used to copy specific uplink messages to the first network port set, so that the network port corresponding to the first Ethernet port of the host machine and the network port corresponding to the first Ethernet port of the board-level management controller can each receive the copied message, which means that the board-level management controller does not need to manage and configure the virtual local area network (VLAN) separately, nor does the board-level management controller need to monopolize the first Ethernet port, thereby reducing the complexity and cost of network management and configuration. In addition, based on the application environment of the network communication method for the board-level management controller, such as the applicable network communication protocol, security specifications, etc., the message copy module can be flexibly set, including setting the first matching condition, so as to achieve the purpose of sharing the first Ethernet port and not needing to configure the virtual local area network separately.In some embodiments, the first matching condition can be set as follows: for example, when the uplink message through the first Ethernet port is an Address Resolution Protocol (ARP) request message, the message copying module performs a message copying action and copies the message to the set of network ports corresponding to the host machine and the board-level management controller; for another example, when the uplink message through the first Ethernet port is a message related to the Neighbor Discovery (ND) protocol of Internet Protocol Version 6 (IPV6), such as a Neighbor Advertisement (NA) message and a Neighbor Solicitation (NS) message, which are similar to ARP reply messages and ARP request messages, the message copying module performs a message copying action and copies the message to the set of network ports corresponding to the host machine and the board-level management controller; for another example, when the uplink message through the first Ethernet port is a Dynamic Host Configuration Protocol (DHCP) message. Protocol, DHCP) multicast message, such as for dynamic management and configuration of user network protocol addresses, the message copying module performs the message copying action and copies it to the network port set corresponding to the host machine and the board-level management controller. In this way, by deploying the message copying module and setting the corresponding first matching condition, when the board-level management controller uses the Ethernet port, the corresponding table entry is sent to the message copying module, which can flexibly adapt to various communication protocol specifications, such as Internet Protocol Version 4 (IPV4) and IPV6, and copy specific uplink messages such as ARP messages, ND messages, NA messages, NS messages, and DHCP multicast messages passing through the first Ethernet port to the first network port set, which saves the loss of configuring an independent VLAN for the board-level management controller and also meets the needs of business isolation.

[0031] Continue to refer Figure 1In step S103, a scheduling module is provided through the first network interface card, wherein the scheduling module is used to execute a downlink speed limit strategy for downlink traffic through the first Ethernet port, wherein the downlink speed limit strategy defines the maximum bandwidth and the maximum burst bandwidth of the board-level management controller and the maximum bandwidth and the maximum burst bandwidth of the host machine. In this way, through the optimization of the software and hardware levels of the first network interface card, on the basis of the above-mentioned message replication module, a scheduling module is further provided, thereby further improving the downlink message processing process on the basis of improving the uplink message processing process. When the first Ethernet port of the first network interface card is shared between the host machine and the board-level management controller, in order to ensure that the host machine can fully utilize the bandwidth of the first Ethernet port, and to ensure that the board-level management controller has sufficient bandwidth to provide various functions and services, such as temperature, voltage, fan, bus monitoring, etc., and considering that back pressure may be generated when there is a large traffic competition at the first Ethernet port, the scheduling module executes a downlink speed limit strategy for the downlink traffic through the first Ethernet port, thereby limiting the maximum bandwidth and maximum burst bandwidth of the board-level management controller and the maximum bandwidth and maximum burst bandwidth of the host machine. This means that when there is a large traffic competition at the Ethernet port and back pressure is generated, the bandwidth resources of the board-level management controller can also be ensured, such as a network rate of 100 megabits per second, which is sufficient to support the use of the network controller sideband interface technology to realize network communication between the board-level management controller and the simplified media independent interface on the board where the first network interface card is located. In addition, the host machine's need to fully utilize bandwidth resources is met, which is conducive to improving message forwarding performance.

[0032] Continue to refer Figure 1In step S105, the message replication module and the scheduling module of the first network interface card are used to share the first Ethernet port between the host machine and the board-level management controller, and to realize network communication between the board-level management controller and the simplified media independent interface of the first network interface card. In this way, there is no need to configure a virtual local area network separately, nor is there a need to isolate the use of the Ethernet port in time or space. The first Ethernet port on the first network interface card can be shared between the host machine and the board-level management controller, and the correct message forwarding function is ensured by the above-mentioned message replication module, avoiding the need to manage and configure an independent virtual local area network separately, and the above-mentioned scheduling module avoids bandwidth competition, ensures the service quality of the board-level management controller, and avoids the service of the board-level management controller being squeezed by the host machine service, resulting in a small overall bandwidth. In this way, on the basis of arranging the Ethernet port on the network interface card to be shared between the board-level management controller and the host machine, by optimizing the network interface card at the software and hardware levels, and then improving the uplink message processing flow and the downlink message processing flow, not only the Ethernet port is shared between the board-level management controller and the host machine, but also business isolation is ensured, resource conflicts are avoided, and the bandwidth resources of the board-level management controller are ensured, which is conducive to improving server density, providing richer functions and services, and helping to reduce costs and improve resource utilization.

[0033] Figure 2 A schematic diagram of a network interface card for a board-level management controller provided in an embodiment of the present application. Figure 2As shown, the network interface card includes multiple Ethernet ports, namely Ethernet port A240, Ethernet port B242, and Ethernet port C244. The network interface card 220 used for the board-level management controller 201, and the network communication method provided for the board-level management controller 201 includes: providing a message copying module 221 through the network interface card 220, wherein the message copying module 221 is used to copy the uplink message that passes through the first Ethernet port (Ethernet port A240) and meets the first matching condition to the first network port set when the first Ethernet port (Ethernet port A240) of the network interface card 220 is shared between the host machine 211 and the board-level management controller 201, and the first network port set includes the network port B213 of the host machine 211 corresponding to the first Ethernet port (Ethernet port A240) and the network port A213 of the board-level management controller 201 corresponding to the first Ethernet port (Ethernet port A240). 03; providing a scheduling module 223 through the network interface card 220, wherein the scheduling module 223 is used to execute a downlink speed limit strategy for the downlink traffic passing through the first Ethernet port (Ethernet port A240), wherein the downlink speed limit strategy defines the maximum bandwidth and the maximum burst bandwidth of the board-level management controller 201 and the maximum bandwidth and the maximum burst bandwidth of the host machine 211; utilizing the message replication module 221 and the scheduling module 223 of the network interface card 220, sharing the first Ethernet port (Ethernet port A240) between the host machine 211 and the board-level management controller 201, and realizing network communication between the board-level management controller 201 and the simplified media independent interface 230 of the network interface card 220.

[0034] Figure 2 The network interface card 220 shown in the figure, on the basis of arranging that the Ethernet port A240 on the network interface card 220 is shared between the board-level management controller 201 and the host machine 211, optimizes the network interface card 220 at the software level and the hardware level, and then improves the uplink message processing flow and the downlink message processing flow, not only realizes the sharing of the Ethernet port A240 between the board-level management controller 201 and the host machine 211, but also ensures the isolation of services, avoids resource conflicts, ensures the bandwidth resources of the board-level management controller 201, is conducive to improving the server density, providing more abundant functions and services, and is conducive to reducing costs and improving resource utilization. It should be understood that one or more of the multiple Ethernet ports on the network interface card 220 can be used as a shared Ethernet port. In some embodiments, one or more of the multiple Ethernet ports on the network interface card 220 may also be one or more Ethernet ports as Ethernet ports exclusively used by the board-level management controller 201.

[0035] refer to Figure 1 and Figure 2In a possible implementation, the downlink speed limit strategy defines the maximum bandwidth and the maximum burst bandwidth of the board-level management controller and the maximum bandwidth and the maximum burst bandwidth of the host machine, including: the downlink speed limit strategy defines that the maximum bandwidth and the maximum burst bandwidth of the board-level management controller are both preset values, and the downlink speed limit strategy also defines that the maximum bandwidth and the maximum burst bandwidth of the host machine are both the bandwidth of the first Ethernet port. Here, the maximum bandwidth and the maximum burst bandwidth of the board-level management controller are both preset values, and the preset value can be, for example, a network rate of 100 megabits per second, which is sufficient to support the use of the network controller sideband interface technology to realize network communication between the board-level management controller and the simplified media independent interface on the board where the first network interface card is located. In this way, through the optimization of the software and hardware levels of the first network interface card, a scheduling module is further provided on the basis of the above-mentioned message replication module, so that on the basis of improving the uplink message processing flow, the downlink message processing flow is further improved. When the first Ethernet port of the first network interface card is shared between the host machine and the board management controller, it is ensured that the host machine can fully utilize the bandwidth of the first Ethernet port, and that the board management controller has sufficient bandwidth to provide various functions and services.

[0036] In some embodiments, the scheduling module is further used to execute an uplink scheduling strategy for the uplink traffic through the first Ethernet port, wherein the uplink scheduling strategy is determined based on the respective weights of the host machine and the board-level management controller, or the respective priorities of the host machine and the board-level management controller. Thus, the uplink scheduling strategy further provides scheduling flexibility in terms of service traffic, which is conducive to ensuring the service traffic of the board-level management controller.

[0037] In some embodiments, when the uplink scheduling strategy is determined based on the respective weights of the host machine and the board management controller, the weight of the board management controller is higher than the weight of the host machine, and when the uplink scheduling strategy is determined based on the respective priorities of the host machine and the board management controller, the priority of the board management controller is higher than the priority of the host machine. In this way, when the first Ethernet port of the first network interface card is shared between the host machine and the board management controller, it is ensured that the host machine can fully utilize the bandwidth of the first Ethernet port, and that the board management controller has sufficient bandwidth to provide various functions and services.

[0038] In a possible implementation, the first matching condition indicates that when the uplink message is an address resolution protocol request message, a neighbor advertisement message of Internet Protocol version 6, a neighbor solicitation message of Internet Protocol version 6, or a multicast message of Dynamic Host Configuration Protocol, the uplink message is copied to the first network port set. In this way, based on the application environment of the network communication method for the board-level management controller, such as applicable network communication protocols, security specifications, etc., the message copy module can be flexibly set, including setting the first matching condition, so as to achieve the purpose of sharing the first Ethernet port without the need to configure a virtual local area network separately. By deploying a message copy module and setting a corresponding first matching condition, when the board-level management controller uses the Ethernet port, the corresponding table entry is sent to the message copy module, which can flexibly adapt to various communication protocol specifications, such as IPV4 and IPV6, and copy specific uplink messages through the first Ethernet port, such as ARP messages, ND messages, NA messages, NS messages, and DHCP multicast messages, to the first network port set, thereby saving the loss of configuring an independent VLAN for the board-level management controller and also meeting the needs of business isolation.

[0039] In some embodiments, the neighbor advertisement message of Internet Protocol version 6 and the neighbor solicitation message of Internet Protocol version 6 are based on the neighbor discovery protocol of Internet Protocol version 6. In this way, not only the Ethernet port is shared between the board management controller and the host machine, but also the service isolation is ensured, resource conflicts are avoided, and the bandwidth resources of the board management controller are ensured, which is conducive to improving server density, providing richer functions and services, and is conducive to reducing costs and improving resource utilization.

[0040] In a possible implementation manner, the board management controller performs network communication with the first network interface card through the simplified media independent interface, so that the first network interface card is used in an independent network card management manner.

[0041] In some embodiments, the board-level management controller communicates with the second network interface card through the network port of the board-level management controller corresponding to the first Ethernet port in the first network port set, so as to use the second network interface card in accordance with the independent network card management method, wherein the second network interface card is independent of the first network interface card. In this way, when the first Ethernet port of the first network interface card is shared between the host machine and the board-level management controller, the board-level management controller can also be deployed to use the second network interface card in accordance with the independent network card management method, that is, the board-level management controller can refer to the independent network card management method to manage the service network interface card on the mainboard, which helps to provide richer functions, increase the density of the server, and improve resource utilization.

[0042] In some embodiments, the first network interface card and the second network interface card are both mounted on the server where the host machine is located. This helps to provide more abundant functions, increase server density, and improve resource utilization.

[0043] In a possible implementation, when the first Ethernet port of the first network interface card is shared between the host machine and the board-level management controller, there is no conflict between the virtual LAN resources used by the board-level management controller and the virtual LAN resources used by the host machine. In this way, there is no need to configure a virtual LAN separately, nor is there a need to isolate the use of the Ethernet port in time or space. The first Ethernet port on the first network interface card can be shared between the host machine and the board-level management controller, and the correct message forwarding function is ensured by the above-mentioned message replication module, avoiding the need to manage and configure an independent virtual LAN separately, and the above-mentioned scheduling module avoids bandwidth competition, ensuring the service quality of the board-level management controller, and avoiding the board-level management controller's service being squeezed by the host machine's service, resulting in an overall small bandwidth.

[0044] In a possible implementation, the board-level management controller exclusively uses the second Ethernet port of the first network interface card, and the board-level management controller exclusively uses the bandwidth of the second Ethernet port. In this way, when the first Ethernet port of the first network interface card is shared between the host machine and the board-level management controller, the board-level management controller can also be arranged to exclusively use the second Ethernet port of the first network interface card, and the board-level management controller exclusively uses the bandwidth of the second Ethernet port. In this way, the second Ethernet port is exclusively used on the basis of sharing the first Ethernet port, which is conducive to meeting the customized input and output requirements of the board-level management controller, such as providing functions and services with higher requirements for response speed, bandwidth resources, network stability, etc. through the exclusive second Ethernet port, while reducing the overall cost and improving the overall resource utilization through the shared first Ethernet port.
