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

[0060] The terms "including" and "having," as used in the present description and accompanying drawings, and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements and may include steps or elements that are not listed.

[0061] VLANs (Virtual Local Area Networks) created by virtual switches require coordination with physical switch ports for proper communication. Improper physical switch port configuration can lead to cross-host communication anomalies when virtual machines use these VLANs. Therefore, experienced network engineers must plan the virtual and physical network topologies in advance, as these cannot be changed at any time. Existing virtualization platforms manage physical switches for simple display and configuration.

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

[0063] Next, a flowchart of a physical switch port adjustment method provided by an embodiment of the present invention is described in detail. Figure 1 An embodiment of the present invention provides a method for adjusting a physical switch port, which may include:

[0064] S101, determining a physical host, a physical switch, and a virtual switch in a virtualization platform; wherein the 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 the virtual local area network under the physical switch.

[0065] The execution entity of this embodiment is an electronic device, but this embodiment is not limited to a specific electronic device. For example, the electronic device in this embodiment can be a computer, or it can also be a virtual machine. The virtualization platform in this embodiment uses software technology to abstract the hardware resources of a physical computer (such as the CPU (central processing unit), memory, storage, and network), thereby creating multiple isolated virtual environments or virtual machines. Each virtual machine can run its own operating system and applications as if it were an independent physical machine. This technology maximizes the utilization of hardware resources and improves system flexibility and efficiency. 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 Layer 2 (and even some Layer 3) networking functions of a physical switch through software. It allows communication between virtual machines (VMs) and between virtual machines and external networks. The physical network card acts as an uplink, connecting the virtual switch to the external physical network. Virtual machines and virtual network cards are created within the physical host, and the virtual network card selects 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 for 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 for 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, physical switch and virtual switch on the virtualization platform, which improves the accuracy of the setting of the physical host, physical switch and virtual switch.

[0067] It should be further explained that the above-mentioned physical switch information includes the physical switch name, physical switch port number, 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 based on the physical switch information 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 network interface naming method. 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: Receive a port adjustment message through the physical network card, and determine the physical switch information corresponding to each physical network card according to the port adjustment message; wherein the physical switch information is information that determines the correspondence between the physical network card and the 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 primary function of LLDP messages is to establish and maintain neighbor relationships between network devices, enabling them to identify each other and exchange information. By sending and receiving LLDP messages, devices can understand each other's existence, status, and capabilities, enabling better collaboration. For example, the LLDP message information in this embodiment may confirm the name, port number, and MTU (Maximum Transmission Unit) value of the physical switch to which each physical network interface card is connected.

[0070] S103: Determine the port mode type corresponding to the physical switch according to the virtual local area network under the set virtual switch, and adjust 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 the TRUNK type (a physical link used to transmit multiple VLAN (virtual local area network) data streams) and allow the VLAN ID (only then it is allowed to pass).

[0072] It should be further explained that the above-mentioned determination of the port mode type corresponding to the physical switch based on 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 (VLAN), 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 (VLAN), 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 (VLAN), the corresponding port mode type on the physical switch should be the first mode. First mode means that the port carries data flows from only one VLAN. This means that in this mode, the physical switch port only allows packets belonging to that VLAN to pass through, thereby ensuring data security and isolation. This mode is typically used in single VLAN scenarios to simplify network management and security control. When multiple virtual network cards are connected to the same VLAN, the corresponding port mode type on the physical switch should be the second mode. Second mode means that the port can carry data flows from multiple VLANs. This means that in this mode, the physical switch port allows packets from multiple VLANs to pass through, enabling communication and data exchange between different VLANs. This mode is typically used in scenarios requiring cross-VLAN communication to meet more complex network requirements. In this embodiment, the first mode can be ACCESS mode, and the second mode can be TRUNK mode. ACCESS mode, also known as access mode, is a switch port configuration method. In ACCESS mode, a port can belong to only one VLAN (virtual local area network) and can only pass data frames from that 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 user experience by setting different modes.

[0076] S104: Adjust the maximum transmission unit value of the data packet of the physical switch port 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 based on the physical network card binding mode. This embodiment can optimize the distribution and transmission path of network traffic by identifying the physical network card binding mode and adjusting the aggregation mode of the physical switch accordingly, thereby reducing network latency and increasing 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 aggregation 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 using an XOR operation to generate a hash value; 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 redundancy mechanism; wherein, the fourth physical network card binding mode is that all data packets will be broadcast 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 (the first physical NIC bonding mode), Mode = 0 (balance-rr) indicates round-robin load balancing, which works with the switch's forced non-negotiation mode for aggregation. Mode = 1 (the second physical NIC bonding mode) (active-backup) indicates active-backup mode, where only one NIC is active and the other is standby. In this case, if the switch is configured for bonding, it will not work properly because half of the packets sent to both NICs will be discarded. Mode = 2 (the third physical NIC bonding mode) (balance-xor) indicates XOR hash load balancing, which works with the switch's forced non-negotiation mode for aggregation. (xmit_hash_policy is required.)Mode 3 (the fourth physical NIC bonding mode) (broadcast) indicates that all packets are sent from all interfaces. This is unbalanced and only has redundancy mechanisms... and works with the switch's forced non-negotiation aggregation mode. Mode 4 (the fifth) (802.3ad) indicates support for the 802.3ad protocol and works with the switch's LACP aggregation mode (requires xmit_hash_policy). Mode 5 (the sixth) (balance-tlb) selects a slave for transmission based on each slave's load, and uses the slave whose turn it is for reception. Mode 6 (the seventh physical NIC bonding mode) (balance-alb) primarily handles received load through ARP negotiation in the IPv4 context. The driver of this policy intercepts ARP channel association requests sent by the local system and overwrites the original address of the slave device with the hardware address of one of the devices. This embodiment can implement different aggregation methods and load balancing strategies through different physical NIC bonding modes.

[0082] It should be further explained that the switch port adjustment method described above may also include: detecting the port data flow volume of each physical switch and physical network interface card; determining as a target port a port whose port data flow volume exceeds the maximum port data flow volume; utilizing load balancing technology to distribute the target port's flow volume to network interfaces whose port data flow volume does not exceed the maximum port data flow volume; or determining to add a new physical network interface card and utilizing the new physical network interface card to handle the flow volume. This embodiment may also provide a timely alert when a port exceeds the maximum port data flow volume. This embodiment may utilize professional network monitoring tools or software to monitor the port data flow volume of each physical switch and physical network interface card in real time, and determine which ports' data flow volume exceeds the threshold based on a preset maximum port data flow volume threshold. For ports exceeding the maximum port data flow volume, two measures may be taken: first, utilizing load balancing technology to distribute the target port's flow volume to other network interfaces whose port data flow volume does not exceed the maximum port data flow volume; second, adding a new physical network interface card to handle the flow volume. This method can effectively address network congestion and latency issues and improve network performance and stability. By monitoring and managing port data flow volume in real time, potential issues can be promptly identified and addressed.

[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 maintaining the maximum transmission unit value of the data packets of the physical network card corresponding to the physical switch consistent with the adjusted maximum transmission unit value of the data packets of the physical switch, may further include: receiving communication traffic from the current physical network card, performing security checks on the communication traffic using a traffic detection method, determining the traffic detection results, and when the traffic detection results indicate the presence of attack traffic, obtaining logs related to the attack traffic, creating an attack profile based on the logs, identifying the attack source, determining the attack target based on the logs, and maintaining the physical hosts, physical switches, and virtual switches on the virtualization platform based on the attack targets. This embodiment receives communication traffic from the current physical network card using professional network monitoring tools or software. Then, using the traffic detection method, performing security checks on the communication traffic to determine whether attack traffic exists. If attack traffic exists, obtaining logs related to the attack traffic, and creating an attack profile based on the logs. The attack profile can identify the attack source and determine the attack target. Finally, based on the attack target, maintaining the physical hosts, physical switches, and virtual switches on the virtualization platform to repair vulnerabilities and prevent further attacks. This invention can effectively improve network security and stability. By real-time monitoring and management of physical network card communication traffic and performing security checks, potential security issues can be promptly identified and measures taken to address them. At the same time, log analysis and attack profiling can be used to accurately identify attack sources and targets, allowing targeted protective measures to be taken. Furthermore, maintaining the physical hosts, physical switches, and virtual switches on the virtualization platform can further improve network performance and security.

The physical switch and physical network card configuration required by the virtual switch created by the virtualization platform can be automatically identified and configured, reducing the occurrence of network communication anomalies caused by physical switch configuration problems.

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

[0094] S205, obtaining the VLAN network ID 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] Specific modifications to this embodiment, such as Figure 3As shown in the figure, the virtual switch is configured with an MTU value of 1800 and a VLAN network with VLAN ID 20. The virtualization platform identifies that the bonding mode of NIC 1 / 2 on host A under the virtual switch is mode 4 and determines that port aggregation on the physical switch is required. It calls a command to add ports eth-0-1 and eth-0-2 to the aggregation group agg1. The bonding mode of NIC 1 / on host B is determined to be mode 1, so aggregation is not required and no task is triggered. The virtualization platform identifies that the virtual switch MTU is 1800 and calls the physical switch command to change the MTU of the agg1 aggregation group to 1800 and the MTU of eth-0-3 and eth-0-4 to 1800. The virtualization platform also calls the host command to synchronously change the MTU of network adapters 1 / 2 of host A and 1 / 2 of host B to 1800. The virtualization platform identifies the service network with VLAN ID 20 created on the virtual switch and configures the port mode of the agg1 aggregation group, eth-0-3, and eth-0-4 on the physical switch to trunk, allowing VLAN 20 to pass.

[0096] S206: Obtain the maximum transmission unit value of the data packet of the created virtual switch, and call a 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-network card bonding mode, a corresponding port aggregation group is created according to the bonding mode.

[0098] The multi-NIC bonding mode in this embodiment corresponds to the physical NIC bonding mode mentioned above. For example, Linux bondmode4 requires configuring 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 As shown in the figure, this embodiment performs a high-traffic stress test on two virtual machines. Because 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 network card's maximum transmission value, triggering an excessive pressure alarm for network card 1 of host B. This embodiment can be horizontally expanded based on 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 virtual switch configuration VLAN network, physical network card binding mode, MTU configuration, etc., so that the physical switch network can flexibly adapt to virtualized network resources.
