Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
First, the term "and" in the embodiment of the present application is only one kind of association relationship describing an associated object, and means that three kinds of relationships may exist, for example, a and B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
When the present application refers to the ordinal numbers "first", "second", "third" or "fourth", etc., it should be understood that this is done for differentiation only, unless it is clear from the context that the order is actually expressed.
The scheme of the present application will be described in detail by specific examples, but the present application is not limited to the following examples.
Exemplarily, referring to fig. 1, the present application provides a network networking schematic diagram, where the network networking includes a server 1 and a server 2 connected to a switch, respectively, the server 1 is deployed with a virtual machine 1(VM 1) and a virtual machine 2(VM 2), and an intelligent network card 1 on the server 1 is configured with virtual function interfaces 1(VF 1) corresponding to the VM 1 one to one and virtual function interfaces 2(VF 2) corresponding to the VM 2 one to one; a virtual machine 3(VM 3) is deployed on the server 2, and virtual function interfaces 3(VF 3) corresponding to the VM 3 one to one are configured on the intelligent network card 2 on the server 2. In this embodiment of the present application, a mapping relationship between a communication address of each virtual machine and a VF interface corresponding to each virtual machine is maintained in a switch.
The following will describe the method embodiment of the present application in detail by using a specific embodiment, for example, referring to fig. 2, the message processing method provided by the present application is applied to an intelligent network card, a switch connected to the intelligent network card maintains a mapping relationship between a communication address of each virtual machine and a virtual function VF interface corresponding to each virtual machine, and the detailed flow of the message processing method is as follows:
step 200: and receiving a first message sent by the first virtual machine.
In this embodiment of the application, before performing step 200, the message processing method may further include: and when the intelligent network card determines to start locally, the intelligent network card sends a handshake message to the switch. And if a response message returned by the switch based on the handshake message is received, reporting the information of each local VF interface to the switch, so that the switch allocates an identifier for uniquely identifying the VF interface for each VF interface.
In practical applications, the intelligent network card may include a plurality of physical ports, and each physical port may be configured with at least one virtual function interface. After the intelligent network card is started, the intelligent network card can respectively send HELLOW messages of 802.1BR to the switch from each physical port, and if response messages of the switch are received, the intelligent network card takes each local VF interface as a remote port of the switch. The intelligent network card can report all local VF interface information to the switch, so that the switch allocates an expansion port number (identifier) to each VF interface, where the expansion port number of one VF interface can be used to uniquely identify the VF interface.
Step 210: and judging whether a forwarding table item matched with the first message exists locally.
In the embodiment of the application, the intelligent network card locally maintains a local forwarding table, that is, messages between VMs in the server are forwarded without being processed by the switch, and when the intelligent network card receives a message sent by a local virtual machine, the intelligent network card can determine whether the destination virtual machine of the message is local according to the destination communication address of the message, and if so, directly forward the message according to the local forwarding table, or if not, send the message to the switch for subsequent forwarding processing.
For example, as shown in fig. 1, VM 1 sends a message 1 to VM 2, then, when receiving the message 1, the intelligent network card determines that the destination MAC address of the message 1 is the MAC address of VM 2, and a forwarding table entry matching the MAC address of VM 2 exists in the local MAC forwarding table, then the intelligent network card directly forwards the message 1 according to the forwarding table entry, and does not need to upload the message 1 to the switch.
Step 220: and when judging that no forwarding table item matched with the first message exists locally, sending the first message to a switch, so that the switch determines a target VF interface corresponding to the target communication address of the first message in the mapping relation between the communication address of each virtual machine and the VF interface corresponding to each virtual machine, and sending the message to a corresponding second virtual machine through the target VF interface.
In this embodiment, when receiving a message, the intelligent network card determines that a local forwarding table entry matching a destination communication address of the message does not exist in a local forwarding table, and then the message needs to be sent to the switch for processing.
For example, as shown in fig. 1, VM 1 sends a message 2 to VM 3, then, when receiving the message 2, the intelligent network card determines that a destination MAC address of the message 2 is an MAC address of VM 3, and a local MAC forwarding table does not have a forwarding table entry matching the MAC address of VM 3, then, the intelligent network card uploads the message 2 to the switch, and the switch determines a VF interface (VF 3) corresponding to the MAC address of VM 3 according to the MAC address of VM 3 and a mapping relationship between the locally maintained MAC address and VF interface, and sends the message 2 to VF 3, so that the intelligent network card sends the message 2 to VM 3 corresponding to VF 3.
In this embodiment of the application, when the first message is sent to the switch, a preferred implementation manner is to obtain an identifier of a VF interface corresponding to a first virtual machine, and add the identifier of the VF interface corresponding to the first virtual machine to the first message to obtain a second message; and sending the second message to the switch.
That is to say, the switch receives the message reported by the intelligent network card and carries the identification information of the VF corresponding to the source virtual machine, and accordingly, if the switch can perform self-learning of the communication address of the virtual machine and the identification of the VF interface corresponding to the virtual machine. The specific self-learning process of the communication address of the virtual machine and the VF interface identifier corresponding to the virtual machine is described in detail below, and is not described herein again.
In this embodiment, if the received packet is a broadcast packet or a multicast packet, because the broadcast group address or the multicast group address also has at least one corresponding extended port number (at least one VF interface identifier), and the broadcast packet or the multicast packet carries the VF interface identifier corresponding to the source virtual machine, the intelligent network card may also perform source port filtering according to the VF interface identifier corresponding to the source virtual machine, so as to prevent the source virtual machine from receiving the packet sent by the intelligent network card.
Illustratively, referring to fig. 3, another message processing method provided in the present application is applied to a switch, where a mapping relationship between a communication address of each virtual machine and a virtual function VF interface corresponding to each virtual machine is maintained in the switch, and a detailed flow of the message processing method is as follows:
step 300: receiving a first message sent by the intelligent network card, wherein the first message is a message sent by the first virtual machine.
In this embodiment, the intelligent network card receives a message, and when it is determined that the destination virtual machine of the message is not local, the intelligent network card sends the message to the switch, so that the switch performs subsequent forwarding processing on the message.
In this embodiment, when receiving a packet (e.g., a first packet), and when determining that the packet is a packet addressed to a virtual machine on another server, the intelligent network card may encapsulate the packet, and specifically, may add an identifier of a VF interface corresponding to a source virtual machine that sends the packet to the packet, to obtain a second packet carrying an identifier of the VF interface corresponding to the source virtual machine that sends the packet.
Then, the packet received by the switch is the packet carrying the VF interface identifier corresponding to the source virtual machine that sent the packet.
Further, the switch may perform learning of a mapping relationship between the communication address of the source virtual machine and the VF interface identifier corresponding to the source virtual machine (forwarding table entry self-learning process).
Specifically, in this embodiment of the present application, the first packet carries an identifier of a VF interface corresponding to the first virtual machine; the method further comprises the following steps: judging whether a mapping relation between the communication address of the first virtual machine and the identifier of the VF interface corresponding to the first virtual machine exists in the mapping relation between the communication address of each locally maintained virtual machine and the VF interface corresponding to each virtual machine; and if the mapping relation does not exist, adding the mapping relation between the communication address of the first virtual machine and the identifier of the VF interface corresponding to the first virtual machine into the mapping relation between the communication address of each virtual machine and the VF interface corresponding to each virtual machine.
Step 310: and determining a target VF interface corresponding to the target communication address of the first message in the mapping relation between the communication address of each virtual machine and the VF interface corresponding to each virtual machine.
As can be seen from the above, the switch may learn a mapping relationship between a communication address of a source virtual machine and a VF interface identifier corresponding to the source virtual machine, so that the switch locally maintains the mapping relationship between the communication address of each virtual machine and a virtual function VF interface corresponding to each virtual machine, and then the switch may determine an outgoing interface (VF interface identifier) corresponding to the destination communication address according to a destination communication address of a received packet.
Step 320: and sending the message to a corresponding second virtual machine through the target VF interface.
As can be seen from the above, the intelligent network card only needs to maintain the mapping relationship between the VF interface identifier and the VF locally, that is, the mapping relationship between the VF interface identifier and the virtual machine, and when the intelligent network card receives a message sent by the switch, the intelligent network card can determine the VF interface (or determine the target virtual machine) according to the VF interface identifier carried by the message, thereby completing forwarding of the message.
