Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] The VLAN (Virtual Local Area Network) network created by the virtual switch needs to cooperate with the port of the physical switch to communicate normally. If the physical switch port is configured incorrectly, it will cause abnormal cross-host communication when the virtual machine uses the VLAN network. Therefore, experienced network engineers are required to plan the layout of virtual and physical network topologies in advance, which cannot be changed at any time. The existing virtualization platform manages physical switches for simple display and configuration.

[0062] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0063] Next, a flow chart of a physical switch port adjustment method provided by an embodiment of the present invention is described in detail. Figure 1 A physical switch port adjustment method provided by an embodiment of the present invention may include:

[0064] S101, determining a physical host, a physical switch and a virtual switch in a virtualization platform; wherein a physical network card of the physical host is associated with the virtual switch as an uplink; creating a virtual machine and a virtual network card in the physical host, and the network used by the virtual network card is a virtual local area network under the physical switch.

[0065] The execution subject of this embodiment is an electronic device, and this embodiment does not limit the specific electronic device. For example, the electronic device in this embodiment can be a computer, or the electronic device in this embodiment can also be a virtual machine. The virtualization platform in this embodiment is a method of abstracting the hardware resources (such as CPU (central processing unit), memory, storage and network) of a physical computer using software technology to create multiple isolated virtual environments or virtual machines. Each virtual machine can run its own operating system and applications as if they were independent physical machines. This technology can maximize the use of hardware resources and improve the flexibility and efficiency of the system. In this embodiment, the physical host, physical switch and virtual switch are created on the virtualization platform. In a virtualized environment, a virtual switch (vSwitch) is a technology that implements the second layer (or even part of the third layer) network function of a physical switch by software. It allows communication between virtual machines (VMs) and between virtual machines and external networks. The physical network card is used as an uplink to connect the virtual switch to the external physical network. Create a virtual machine and a virtual network card in the physical host, and the virtual network card chooses to use the network under the virtual switch.

[0066] It should be further explained that before determining the physical host, physical switch and virtual switch in the virtualization platform, it can also include: setting the first physical network card and the second physical network card on the first physical host of the virtualization platform, and setting the third physical network card and the fourth physical network card on the second physical host; adding the first physical network card, the second physical network card, the third physical network card and the fourth physical network card as uplinks to the virtual switch; connecting the first physical network card to the first port of the physical switch, the second physical network card to the second physical network card of the physical switch, the third physical network card to the third port of the physical switch, and the fourth physical network card to the fourth physical network card of the physical switch; determining the setting of the aggregation mode of the first physical network card and the second physical network card on the first physical host on the virtual switch; determining the setting of the master-slave mode of the third physical network card and the fourth physical network card on the virtual switch. This embodiment provides a specific setting method for the physical host, the physical switch and the virtual switch on the virtualization platform, which improves the accuracy of the setting of the physical host, the physical switch and the virtual switch.

[0067] It should be further explained that the above-mentioned physical switch information includes the physical switch name of the physical switch, the physical switch port number, the maximum transmission unit value of the physical switch port data packet, and the corresponding physical host name and physical network card name; accordingly, the above-mentioned switch port adjustment method may also include: determining the physical switch name and physical switch port number corresponding to the physical network card according to the physical switch information, so as to connect the physical switch with the corresponding physical network card. For example, physical network card 1 is connected to the eth-0-1 port of the physical switch, and physical network card 2 is connected to the eth-0-2 port, where eth is the naming method of the network interface. This embodiment can accurately connect the physical switch and the physical network card through the physical switch information, and set the accurate physical switch port.

[0068] S102, receiving a port adjustment message through a physical network card, and determining physical switch information corresponding to each physical network card according to the port adjustment message; wherein the physical switch information is information for determining a correspondence between a physical network card and a physical switch port.

[0069] The port adjustment message in this embodiment may be an LLDP message, which is a data packet used by the Link Layer Discovery Protocol (LLDP) to exchange information between network devices. The main function of the LLDP message is to establish and maintain neighbor relationships between network devices so that they can recognize and exchange information with each other. By sending and receiving LLDP messages, devices can understand each other's existence, status, and capabilities, so as to work better together. For example, the LLDP message information in this embodiment can confirm the name, port number, and MTU value (Maximum Transmission Unit) of the physical switch to which each physical network card is connected.

[0070] S103, determining the port mode type corresponding to the physical switch according to the virtual local area network under the set virtual switch, and adjusting the port of the physical switch according to the port mode type.

[0071] The virtualization platform in this embodiment obtains the VLAN network id created under the created virtual switch, and can call the physical switch background command according to the set VLAN network id to modify the port mode of the corresponding physical switch, for example, to modify it to the TRUNK type (a physical link for transmitting multiple VLAN (virtual local area network) data streams) and allow the VLAN id (to allow it to pass).

[0072] It should be further explained that, the above-mentioned determination of the port mode type corresponding to the physical switch according to the virtual LAN under the set virtual switch may include:

[0073] S1031, if a virtual network card is connected to a virtual local area network, determine that the port mode type corresponding to the physical switch is a first mode; wherein the first mode is a mode for carrying a virtual local area network data flow;

[0074] S1032: If multiple virtual network cards are connected to the same virtual local area network, determine that the port mode type corresponding to the physical switch is a second mode; wherein the second mode is a mode for carrying multiple virtual local area network data flows.

[0075] In this embodiment, when a virtual network card is connected to a virtual local area network, the port mode type corresponding to the physical switch should be the first mode. The first mode means that the port only carries the data flow of one virtual local area network. This means that in this mode, the port of the physical switch only allows data packets belonging to the VLAN to pass, thereby ensuring the security and isolation of the data. This mode is usually used in the case of a single VLAN to achieve simple management and security control of the network. When multiple virtual network cards are connected to the same virtual local area network, the port mode type corresponding to the physical switch should be the second mode. The second mode means that the port can carry data flows of multiple virtual local area networks. This means that in this mode, the port of the physical switch allows data packets of multiple VLANs to pass, thereby achieving communication and data exchange between different VLANs. This mode is usually used in scenarios where cross-VLAN communication is required to meet more complex network requirements. The first mode in this embodiment can be ACCESS mode, and the second mode can be TRUNK mode. ACCESS mode: also known as access mode, is a configuration method of the switch port. In ACCESS mode, the port can only belong to one VLAN (virtual local area network) and can only pass data frames of the VLAN. That is to say, when a data frame is sent from a device to the ACCESS mode port of the switch, the switch will check the VLAN tag of the data frame. If it is the same as the VLAN to which the port belongs, it will be allowed to pass; otherwise, the data frame will be discarded. This mode is usually used to connect terminal devices such as computers and printers, because they usually only need to access one VLAN. TRUNK mode: also known as trunk mode or aggregation mode, is another way to configure the switch port. In TRUNK mode, the port can allow data frames from multiple VLANs to pass through, and can forward data frames between different VLANs. This means that when a data frame is sent from a device to the TRUNK mode port of the switch, the switch will not check the VLAN tag of the data frame, but will directly forward it to another VLAN. This mode is usually used to connect network devices such as routers and other switches to achieve communication and data exchange between different VLANs. This embodiment can meet the different needs of users and improve the user experience by setting different modes.

[0076] S104, adjusting the maximum transmission unit value of the data packet of the port of the physical switch according to the set maximum transmission unit value of the data packet of the port of the virtual switch.

[0077] In this embodiment, the MTU value of the created virtual switch can be obtained, and then the physical switch command can be called to reconfigure the MTU of the corresponding port to be consistent.

[0078] S105, determining a physical network card corresponding to the physical switch based on the physical switch information, and making the maximum transmission unit value of the data packet of the physical network card corresponding to the physical switch consistent with the adjusted maximum transmission unit value of the data packet of the physical switch.

[0079] In this embodiment, a host command is called to reconfigure the physical network card MTU to be consistent.

[0080] It should be further explained that the switch port adjustment method may also include: identifying the physical network card binding mode of the physical host under the virtual switch; and determining the aggregation mode of the physical switch according to the physical network card binding mode. This embodiment can optimize the distribution and transmission path of network traffic by identifying the binding mode of the physical network card and adjusting the aggregation mode of the physical switch accordingly, thereby reducing network delay and improving data transmission rate.

[0081] It should be further explained that the above-mentioned determination of the aggregation mode of the physical switch according to the physical network card binding mode may include: when the physical network card binding mode is the first physical network card binding mode, determining that the aggregation mode of the physical switch is aggregation forced non-negotiation; wherein the physical network card binding mode is a load sharing rotation mode, and the first aggregation forced non-negotiation is a mode of forming an aggregated link by bundling multiple physical ports together without using negotiation; when the physical network card binding mode is the second physical network card binding mode, determining that the aggregation mode of the physical switch is the bundling mode; wherein the second physical network card binding mode is the master-slave mode; when the physical network card binding mode is the third physical network card binding mode, determining that the aggregation mode of the physical switch is the aggregation forced non-negotiation mode based on the hash transmission strategy; wherein the third physical network card binding mode is to use A method for load sharing by generating a hash value using an XOR operation; when the physical network card binding mode is the fourth physical network card binding mode, determining the aggregation mode of the physical switch to be an aggregation forced non-negotiation mode under a redundant mechanism; wherein the fourth physical network card binding mode is that all data packets will be broadcasted from all interfaces; when the physical network card binding mode is the fifth physical network card binding mode, determining the aggregation mode of the physical switch to be an aggregation mode based on the link aggregation control protocol; wherein the fifth physical network card binding mode is a mode that supports the IEEE802.3ad protocol; when the physical network card binding mode is the sixth physical network card binding mode, determining the aggregation mode of the physical switch to be a mode based on a load balancing algorithm; when the physical network card binding mode is the seventh physical network card binding mode, determining the aggregation mode of the physical switch to be a mode based on an address load balancing algorithm. The IEEE802.3ad protocol in this embodiment is also called LACP (Link Aggregation Control Protocol), which is a data link layer protocol used to combine multiple physical links to create an aggregated link. In this embodiment (first physical network card binding mode) Mode=0(balance-rr) indicates load sharing round-robin, which cooperates with the aggregation forced non-negotiation mode of the switch. Mode=1 (second physical network card binding mode) (active-backup) indicates active-standby mode, where only one network card is active (main) and the other is standby (backup). At this time, if the switch is equipped with bundling, it will not work properly because half of the packets sent by the switch to the two network cards are discarded. Mode=2 (third physical network card binding mode) (balance-xor) indicates XOR Hash load sharing, which cooperates with the aggregation forced non-negotiation mode of the switch. (xmit_hash_policy is required).Mode=3 (the fourth physical network card binding mode) (broadcast) means that all packets are sent from all interfaces. This is unbalanced, and there is only a redundancy mechanism... and the aggregation forced non-negotiation mode of the switch is coordinated. Mode=4 (the fifth) (802.3ad) means that the 802.3ad protocol is supported, and it cooperates with the aggregation LACP mode of the switch (xmit_hash_policy is required). Mode=5 (the sixth) (balance-tlb) selects the slave for sending according to the load of each slave, and uses the slave whose turn is currently when receiving. Mode=6 (the seventh physical network card binding mode) (balance-alb) In the case of IPV4, this strategy mainly processes the received load through ARP negotiation. The driver of this strategy intercepts the channel joint request sent by ARP in the local system, and uses one of the device hardware addresses to overwrite the original address of the slave device. This embodiment can achieve different aggregation methods and different load balancing strategies through different physical network card binding modes.

[0082] It should be further explained that the switch port adjustment method may also include: detecting the port data flow size of each physical switch and physical network card; determining the port whose port data flow size is greater than the maximum port data flow as the target port; using load balancing technology to distribute the flow of the target port to the network card whose data flow is not greater than the maximum port data flow; or determining to add a new physical network card, and using the new physical network card to undertake the flow. This embodiment can also issue a timely alarm when the port exceeds the maximum port data flow. This embodiment can monitor the port data flow of each physical switch and physical network card in real time through professional network monitoring tools or software, and determine which ports have exceeded the data flow threshold according to the preset maximum port data flow threshold. For these ports that exceed the maximum port data flow, two measures can be taken: one is to use load balancing technology to distribute the flow of the target port to other network cards that do not exceed the maximum port data flow; the other is to add a new physical network card to undertake the flow. This method can effectively solve network congestion and delay problems and improve network performance and stability. By real-time monitoring and management of port data flow, potential problems can be discovered in time and measures can be taken to solve them.

[0083] It should be further explained that the above-mentioned physical switch port adjustment method, after determining the physical network card corresponding to the physical switch based on the physical switch information, and keeping the maximum transmission unit value of the data packet of the physical network card corresponding to the physical switch consistent with the maximum transmission unit value of the adjusted physical switch data packet, can also include: receiving the communication traffic of the current physical network card, using the traffic detection method to perform security detection on the communication traffic, determining the traffic detection result, when the traffic detection result is that there is attack traffic, obtaining logs related to the attack traffic, performing attack profiling based on the logs, identifying the attack source, determining the attack target based on the logs, and maintaining the physical host, physical switch and virtual switch on the virtualization platform based on the attack target. This embodiment receives the communication traffic of the current physical network card through a professional network monitoring tool or software. Then, the communication traffic is security detected using the traffic detection method to determine whether there is attack traffic. If there is attack traffic, logs related to the attack traffic are obtained, and attack profiling is performed based on the logs. Through the attack profiling, the attack source can be identified and the attack target can be determined. Finally, the physical host, physical switch and virtual switch on the virtualization platform are maintained based on the attack target to repair vulnerabilities and prevent further attacks. The present invention can effectively improve the security and stability of the network. By real-time monitoring and management of the communication traffic of the physical network card and performing security detection, potential security issues can be discovered in a timely manner and measures can be taken to deal with them. At the same time, log analysis and attack profiling can be used to accurately identify the attack source and determine the attack target so as to take targeted protective measures. In addition, maintenance of the physical host, physical switch and virtual switch on the virtualization platform can further improve the performance and security of the network.

[0088] S202, creating a VLAN network under the virtual switch, creating a virtual machine and a virtual network card in the physical host, wherein the network used by the virtual network card is the VLAN network under the virtual switch.

[0089] S203, receiving LLDP messages through the physical network card, confirming the name, port number, and maximum transmission unit value of the physical switch connected to each physical network card, and establishing a database table to record in the platform database.

[0090] The database table in this embodiment may be in the form of Table 1, which is a database table provided by an embodiment of the present invention.

[0091] Table 1 A database table

[0092]

[0093] S204, determining the physical switch and port number corresponding to the physical network card according to the recorded database table.

[0094] S205, obtaining the id of the VLAN network under the created virtual switch, calling the physical switch background command, changing the port mode of the corresponding physical switch to the TRUNK type, and allowing the VLAN id to pass.

[0095] The specific modifications of this embodiment are as follows: Figure 3As shown in the figure, the virtual switch is configured with an mtu value of 1800, and a VLAN network with a VLAN ID of 20 is created. The virtualization platform identifies that the binding mode of the network card 1 / 2 of host A under the virtual switch is mode4, and determines that port aggregation configuration on the physical switch side is required. The command is called to add ports eth-0-1 and eth-0-2 to the agg1 aggregation group; it is determined that the binding mode of the network card 1 / on host B is mode1, and aggregation is not required, and no task is triggered. The virtualization platform recognizes that the mtu of the virtual switch is 1800, calls the physical switch command to change the mtu of the agg1 aggregation group to 1800, and changes the mtu of eth-0-3 and eth-0-4 to 1800; calls the host command to synchronously change the mtu of host A's network card 1 / 2 and host B's network card 1 / 2 to 1800. The virtualization platform recognizes that the service network with VLAN ID 20 has been created under the virtual switch. After judgment, it configures the port mode of the agg1 aggregation group, eth-0-3, and eth-0-4 under the physical switch to trunk, and allows VLAN 20 to pass.

[0096] S206, obtaining the maximum transmission unit value of the data packet of the created virtual switch, and calling the host command to keep the maximum transmission unit value of the data packet of the physical network card consistent with the maximum transmission unit value of the data packet of the virtual switch.

[0097] S207: When it is determined that the uplink is in a multi-NIC binding mode, a corresponding port aggregation group is created according to the binding mode.

[0098] The multi-NIC bonding mode in this embodiment corresponds to the physical NIC bonding mode described above. For example, Linux bondmode4 requires the configuration of a port aggregation group on the physical switch side. This embodiment can also use the virtualization platform to sense the traffic of each physical switch port and respond to the physical machine NIC corresponding to the port with higher traffic. For example, in Figure 3 In the figure shown, this embodiment performs a large traffic stress test on two virtual machines. Since the network card of host B is in active-standby mode, the bandwidth of network card 1 of host B will be fully loaded. At this time, the platform detects that the traffic load of physical switch port eth-0-3 has reached 90% of the maximum transmission value of the network card, triggering an alarm for excessive pressure on network card 1 of host B. This embodiment can perform horizontal expansion according to the resource usage of physical devices, without the need to frequently add physical devices.

[0099] The embodiment of the present invention links the physical switch to make automatic configuration from aspects such as VLAN network configuration of the virtual switch, physical network card binding mode, and MTU configuration, so that the physical switch network can flexibly adapt to virtualized network resources.
