[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0029] A local area network (LAN) can be a network consisting of a few home computers or an enterprise network consisting of hundreds of computers. The LAN referred to in the virtual local area network (VLAN) specifically refers to a network divided by a router, that is, a broadcast domain. A broadcast domain refers to the range to which a broadcast frame (all destination MAC addresses are 1) can be transmitted, that is, the range that can communicate directly. A layer 2 switch can only build a single broadcast domain. After using the virtual local area network (VLAN) function, it can divide the network into multiple broadcast domains. If there is only one broadcast domain, after the switch receives a broadcast frame, it will forward it to all ports except the receiving port. At this time, there may be only one port that needs to obtain the broadcast information, but the data frame is transmitted throughout the entire network. Therefore, the broadcast information consumes the overall bandwidth of the network, and the computer that receives the broadcast information also consumes part of the CPU time to process it. This causes a lot of unnecessary consumption of network bandwidth and CPU computing power. Using virtual local area network VLAN to divide multiple broadcast domains can improve the overall transmission performance of the network.

[0030] At present, VLAN is configured by using tagged data frames. The change in the structure of tagged packets is that 4 bytes of VLAN information, namely, VLAN tag header, are added after the source MAC address and the destination MAC address. Such packets need to be received by specific equipment, which will increase the requirements for VLAN equipment and increase the complexity of the system.

[0031] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0141] In some embodiments, the device is set to a first device mode.

[0142] S802: Start UDHCPD or TFTPD.

[0143] In some embodiments, the first device starts the UDHCPD and TFTPD processes. The UDHCPD process is used to establish a communication connection for allocating an IP address to the second device. For the upstream access device, UDHCPD selects the LAN port to be accessed by the downstream device, and the downstream access device selects the upstream WAN port as the bound network card. The TFTPD process is used for file transfer.

[0144] S803: Start the timing mechanism.

[0145] In some embodiments, a timing mechanism is started to prevent the device from being in a waiting state under abnormal circumstances. If the timer expires, information indicating that the VLAN information synchronization has failed is fed back.

[0146] S804: Whether to obtain an IP address.

[0147] In some embodiments, it is determined whether the first device receives a DHCP request message sent by the second device. After the first device starts the UDHCPD process, it starts to monitor the DHCP request message of the access device. If the first device receives the DHCP request message sent by the second device, it proceeds to step S806, otherwise it proceeds to step S805 to determine whether the timer has timed out. If not, it maintains the monitoring state.

[0148] S805: Allocate an IP address to the second device and establish a connection.

[0149] In some embodiments, if the first device detects a DHCP request message sent by the second device, it sends a DHCP Offer message to the second device to allocate an IP address to the second device. After the DHCP process is completed, a communication connection is established between the first device and the second device.

[0150] S806: Whether the second device path file is received.

[0151] In some embodiments, the first device determines whether it has received a request from the second device to try the first file. If it has received a request from the second device to send the file, it proceeds to step S807; if it has not received a request, it proceeds to step S811 and waits until the timer times out.

[0152] S807: Select an available path and send the file with the same name to the second device.

[0153] In some embodiments, after receiving the request for the first file sending attempt from the second device, the first device saves a writable path of the local device in a file with the same name, and pushes the file to the path corresponding to the first file sending request from the second device.

[0154] S808: Whether a response from the second device is received.

[0155] In some embodiments, the first device determines whether the corresponding information from the second device is received. If received, the process proceeds to step S809; if not received, the process proceeds to step S811.

[0167] In some embodiments, the association between user terminals or services and logical links can also be achieved by establishing multiple data links between the network access device 200 and the Internet 100.
