[0049] Please refer to figure 1 , figure 1 It is a schematic diagram of the network communication system 10 provided by the embodiment of the present application. In the present application embodiment, the network communication system 10 can enable the user to interact between the user terminal 11 and multiple network devices 13 without modifying the factory IP address of the network device 13, thereby maintaining the current While producing the production cost of network device 13, it is necessary to avoid the user's network communication experience for the network device 13 to perform IP address adjustment operations for network devices 13. The factory IP address is used to indicate the IP address that the corresponding network device 13 has been maintained from the factory; the user terminal 11 can be, but not limited to, smartphones, personal computers, tablets, laptops, etc.

[0050] In the present application embodiment, the network communication system 10 can include a user terminal 11, a switch 12, and a plurality of network devices 13 having the same factory IP address. The user terminal 11 is connected to each other with a first communication port of the switch 12, and a plurality of the network device 13 each connects a second communication port of the switch 12. Among them, the user terminal 11 simulates a plurality of virtual network cards, where the total number of virtual network cards is the same, each of the total number of network devices, each of which corresponds to a virtual network card, and is in the same virtual local area network with the virtual network card. The different network devices 13 respectively correspond to a virtual local area network, whereby each virtual local area network corresponds to a second communication port of the switch 12 and a virtual network card of the user terminal 11.

[0051] In this case, the network communication system 10 is essentially equivalent to a plurality of virtual local area networks that are inconsistent with each other of the user terminal 11, even if the factory IP address of the network device 13 in each virtual local area is the same. It is also possible to directly transmit data transmission to the network device 13 that needs to be accessed directly by defining a virtual local domain network that needs to be transmitted and the second communication port corresponding to the virtual local area network, thereby ensuring that the user can do not modify each network device 13.

And the virtual local area to which each two communication port is given, "VLAN2", "VLAN3", ..., "VLAN 47", "VLAN48" to characterize the identity of the virtual local area network through each virtual LAN ID. At this time, the corresponding simulation creates 47 virtual network cards at the user terminal connected to the first communication port of the switch 12, so that each virtual network card corresponds to a virtual local area network identity, and makes the 47 virtual network cards respectively virtual IP address. It can be expressed in turn to "192.168.3", "192.168.10.47", "192.168.10.47", "192.168.10.48", and in turn, the aforementioned virtual local area network identifies "VLA2", "VLAN3", ..., " VLAN47 "," VLAN48 ". In this case, these 47 virtual network cards will have the same IP network segment "192.168.10" as the factory IP address "192.168.10.253".

[0058] In the present embodiment, the user terminal 11 can generate a message to be transferred to different network devices 13 in response to a user operation, and the user terminal 11 will be transmitted separately by each of its virtual network cards. Ways, determine if data interaction is performed. Among them, if there is a virtual network card to be transferred, the source IP address of the message to be transferred is the virtual IP address of the virtual network card to be transferred, and the destination IP address of the message to be transferred. For the factory IP address, the pending message will correspond to the virtual local area network identity corresponding to the virtual network card to be transferred to the message to be transmitted, so that the switch 12 determines which second communication needs to be transmitted. Port is transmitted.

[0059] A virtual network card 1 corresponding to the virtual local area network identifies "VLAN2", when the virtual network card 1 generates a message to be transferred, the source IP address of the message to be transferred is virtual IP address of the virtual network card 1 "192.168 .10.2 ", the destination IP address to be transmitted is the factory IP address" 192.168.10.253 ", which logs that the virtual local area network recorded by the message is identified as the virtual local area network identifier" VLAN2 "corresponding to the virtual network card 1.

[0060] When the user terminal 11 determines that the respective virtual network cards are generated, the generated plurality of the pending packets will be added to the same trunk to pass through the switch connected to the user terminal 11. 12 The first communication port of 12 is transmitted to the switch 12 to the switter 12.

[0061] Step S220, the switch reads the virtual local area network identity included in the transmitted message for each of the received packets, and selects the second communication port corresponding to the virtual local area network to transmit the information to be transmitted. Network devices connected to the second communication port.

[0062] In the present embodiment, since the multiple network device 13 has the same factory IP address, the destination IP address of all the transmitted packets received by the switch 12 is the factory IP address, so the switch 12 is determined. When each said network device 13 needs to be transferred to which network device 13 is forwarded, it is necessary to distinguish the network device to be transferred to the network device to be transmitted by reading the virtual local area network identity included in each of the pending messages. 13. Among them, after each of the information to be transferred, the switch 12 selects the second communication port corresponding to the virtual LAN ID to be transmitted to the second communication port corresponding to the virtual local area network identification. The text is transmitted to transmit the information to be transferred to the network device 13 that needs to be transmitted.

Therefore, when a network device 13 generates a target data message that needs to be transmitted to the user terminal 11, the destination IP address of the target data message is in the same virtual local area network with the network device 13 generated by the target data. The virtual IP address of the virtual network card, the source IP address of the target data message, is the factory IP address of the network device 13 of the target data message, which will record the network that generates the target data message. Virtual LAN ID corresponding to device 13.

[0067] After the network device 13 generates a target data packet, the generated target data packet is transmitted to the switch 12 through the second communication port of the switch 12 to the network device 13.

[0068] Step S240, the switch transmits the target data packet to the user terminal to the user terminal with the target data packet to the user terminal to the user terminal to the user terminal.

[0069]In the present embodiment, when the switch 12 receives a target data message, the virtual local area network identity included in the target data message is read accordingly to determine if the target data message needs to be transmitted to other networks. Device 13, whether it is necessary to transmit to the user terminal 11. Among them, when the virtual LAN ID recorded by the target data message is matched to each other with the virtual local area where the network device generated by the target data packet is matched, that is, the target data packet needs to be transmitted to the user terminal 11, and is not transmitted. To other network devices 13. At this time, the switch 12 transmits the target data packet to the user terminal 11 by a first communication port connected to the user terminal 11, so that the user terminal 11 assigns the target data message to the corresponding. The virtual IP address is the same virtual network card as the source IP address of the target data packet. At this time, the virtual network card that receives the target data message is identified by the same virtual LAN ID.
