Description

Technical Field

[0001] This application relates to the field of communications, and in particular to a method, apparatus, electronic device, and medium for adaptive setting of router network ports. Background Technology

[0002] Most mainstream routers nowadays have LAN (local area network) / WAN (wide area network) auto-sensing capabilities. All ports on such routers can automatically determine whether the connection is to a PC or a gateway device and set the corresponding port as either WAN or LAN. This allows the network cable connecting to the optical modem to be connected to any port on the router, instead of being restricted to a specific port. However, this method requires sending probe packets to the LAN bridge interface, and the code structure for receiving reply packets through the kernel is complex and resource-intensive. Since probe packets need to be sent to all four ports, the kernel will send unnecessary packets to the application layer, causing the router to lag during port detection. Summary of the Invention

[0022] Monitor the LAN bridge interface, and when the application layer receives a reply message, determine whether the reply message belongs to the preset reply message;

[0023] If so, disconnect the network port to be tested from the LAN bridge interface and set the network port to be tested as a WAN port;

[0024] If not, then set the network port to be tested as a LAN port.

[0025] Optionally, after the step of setting the network port under test as a WAN port when the application layer receives a preset reply message while monitoring the LAN bridge interface, the method further includes:

[0026] Store the setting result of the network port to be tested as a WAN port to obtain the WAN port identifier corresponding to the network port to be tested;

[0027] When a network cable is detected connected to another physical network port of the router, the WAN port identifier is added to the online message.

[0069] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0070] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0071] Example 1

[0072] Most mainstream routers on the market now have LAN / WAN auto-sensing capabilities. Routers with this capability can automatically determine whether the connected device is a PC or a gateway device and set the corresponding port as either WAN or LAN. Therefore, users can connect the network cable to the optical modem to any port on the router instead of being restricted to a specific port. However, this method requires sending probe packets to the LAN bridge interface, and the kernel's packet reception method has a complex code structure and high resource consumption. It requires sending probe packets to all four ports, and the kernel will send unnecessary packets to the application layer, which can cause the router to lag during the port detection process.

[0073] This application provides a method for setting up a router's network port adaptively. In the first embodiment of this application's method for setting up a router's network port adaptively, refer to... Figure 1 The router port adaptive setting method includes:

[0074] Step S10: Add the network port under test of the router to the LAN bridge interface, and send a probe packet to the network port under test through the application layer, wherein the source MAC address of the probe packet is the MAC address of the LAN bridge interface.

[0075] Step S20: Monitor the LAN test bridge interface. When the application layer receives a preset reply message, set the network port under test to the WAN port; otherwise, set the network port under test to the LAN port.

[0076] In this embodiment, it should be noted that the purpose of setting the source MAC address of the probe packet to the MAC address of the LAN bridge interface is to forge the source MAC address of the probe packet, thereby sending the probe packet at the application layer and receiving the reply packet at the application layer, which improves the utilization of the application layer, eliminates the need to design a complex kernel code structure, and improves the efficiency of network interface detection.

[0077] As an example, steps S10 to S20 include: when a network cable is detected connected to the network port under test, the network port under test is added to the LAN bridge interface; a socket for the probe packet is created based on the PF_PACKET interface, a DHCP discovery packet and a PADI packet are created, and the probe packet is generated; the source MAC address of the probe packet is modified to the MAC address of the LAN bridge interface, and the probe packet is sent to the network port under test through the application layer; the network port under test in the LAN bridge interface is monitored, and when the network port under test sends a reply packet, the reply packet is received through the application layer; if the reply packet is the preset reply packet, the network port under test is set as a WAN port; if the reply packet is not the preset reply packet, the network port under test is set as a bridge port, i.e., a LAN port.

[0078] As an example, the LAN bridge interface is br0, and the router's physical network ports are eth0, eth1, eth2, and eth3, with the network port under test being eth0. If no WAN port exists on other physical network ports, eth0 is added to the br0 bridge. The source MAC address corresponding to both the DHCP discovery message and the PADI message MAC address is set to the MAC address of br0, and the destination sending interface is set to eth0. The DHCP discovery message and PADI message are sent to eth0 via the application layer. The br0 interface listens for reply messages; if a DHCP offer message or PADO message is received, the eth0 port is set as the WAN port; otherwise, the eth0 port is set as a port under the br0 bridge, i.e., the LAN port.

[0079] The method further includes, prior to the step of adding the router's network port under test to the LAN bridge interface and sending probe packets to the network port under test through the application layer:

[0080] Step A10: When a network cable is detected connected to the network port under test, the kernel transmits the online message of the network port under test to the application layer.

[0081] Step A20: Based on the online message, determine whether the WAN port already exists;

[0082] Step A30: If it already exists, set the network port to be tested as a LAN port;

[0083] Step A40: If it does not exist, then perform adaptive settings on the network port to be tested.

[0084] In this embodiment, it should be noted that the online message includes the corresponding identification information of other physical network ports in the router. The identification information is used to characterize the corresponding network port type. If other physical network ports have been set as WAN ports, the corresponding identification information is the WAN port identifier. The WAN port identifier is used as a reference in the adaptive settings of the network port to be tested. If the router already has a WAN port, then the network port to be tested is set as a LAN port.

[0085] As an example, steps A10 to A40 include: when the router's battery port is connected to a network cable, an online message is transmitted to the application layer through the kernel, wherein the online message includes identification information; based on the identification information, it is determined whether the router already has a WAN port; if the router already has a WAN port, the network port to be tested is set as a LAN port; if the router does not have a WAN port, the network port to be tested is adaptively configured.

[0086] The probe messages include DHCP discovery messages and PADI messages. The steps of adding the router's network port to be tested to the LAN bridge interface and sending probe messages to the network port to be tested through the application layer include:

[0087] Step S11: Add the network port to be tested to the LAN bridge interface;

[0088] Step S12: Configure the message parameters corresponding to the DHCP discovery message and the PADI message respectively, and create the probe message;

[0089] Step S13: Send the probe message to the network port under test through the application layer.

[0090] In this embodiment, it should be noted that the probe message includes DHCP discovery message and PADI message; the message parameters include the source MAC address, destination sending interface, and option field.

[0091] As an example, steps S11 to S13 include: adding the network port to be tested to the LAN bridge interface; creating a socket based on the PF_PACKET interface by configuring the source MAC address, destination sending interface, and option field corresponding to the DHCP discovery message and the PADI message respectively, setting the socket type to SOCK_RAW, and generating the probe message; and sending the DHCP discovery message and the PADI message to the network port to be tested through the application layer.

[0092] The steps of configuring the message parameters corresponding to the DHCP discovery message and the PADI message, and creating the probe message, include:

[0093] Step S121: Set the layer source MAC address corresponding to both the DHCP discovery message and the PADI message to the MAC address of the LAN bridge interface;

[0094] Step S122: The transmission sets the destination sending interface corresponding to both the DHCP discovery message and the PADI message to the network port under test;

[0095] Step S123: Set the option field of the DHCP discovery message to a first preset field, wherein the first preset field is used to characterize the identity of the sending device of the DHCP discovery message;

[0096] Step S124: Create the probe message based on the message parameters, the DHCP discovery message, and the PADI message.

[0097] In this embodiment, it should be noted that, referring to Figure 2 The option field is used to identify the router so that when the router is connected to a router of the same type as a sub-machine, it can send a DHCP discovery message with the SKDETECT option field so that the router of the same type can identify the sub-machine and avoid misidentifying the sub-machine as a gateway.

[0098] As an example, steps S121 to S124 include: setting the layer source MAC address of the DHCP discovery message to the MAC address of the LAN bridge interface; setting the layer source MAC address of the PADI message to the MAC address of the LAN bridge interface; setting the destination sending interface of the DHCP discovery message to the network port under test; setting the destination sending interface of the PADI message MAC address to the network port under test; setting the option field of the DHCP discovery message to a first preset field, wherein the first preset field is used to characterize the identity of the sending device of the DHCP discovery message; and generating the probe message based on the DHCP discovery message, the PADI message, and the message parameters.

[0099] As an example, the first preset field can be SKDETECT.

[0100] The step of monitoring the LAN bridge interface, and when the application layer receives a preset reply message, setting the network port under test as a WAN port; otherwise, setting the network port under test as a LAN port includes:

[0101] Step S21: Monitor the LAN bridge interface. When the application layer receives a reply message, determine whether the reply message belongs to the preset reply message.

[0102] Step S22: If yes, disconnect the network port to be tested from the LAN bridge interface and set the network port to be tested as a WAN port.

[0103] Step S23: If not, then set the network port to be tested as a LAN port.

[0104] In this embodiment, it should be noted that the preset reply message must include at least one of the DHCP offer message and the PADO message in order to determine that the interface type of the interface under test is a WAN port.

[0105] As an example, steps S21 to S23 include: monitoring the network port under test in the LAN bridge interface; when the network port under test sends a reply message, receiving the reply message through the application layer; detecting the reply message; if the reply message is the DHCP provide message or the PADO message, then disconnecting the network port under test from the LAN bridge interface and setting the network port under test as a WAN port; if the reply message is neither the DHCP provide message nor the PADO message, then setting the network port under test as a LAN port.

[0106] After the step of setting the network interface under test as a WAN port when the application layer receives a preset reply message while monitoring the LAN bridge interface, the method further includes:

[0107] Step S221: Store the setting result of the network port to be tested as a WAN port to obtain the WAN port identifier corresponding to the network port to be tested;

[0108] Step S222: When a network cable is detected connected to another physical network port of the router, the WAN port identifier is added to the online message.

[0109] In this embodiment, the WAN port identifier is used to identify the router so as to prevent it from being mistakenly identified as a gateway device when the router is used as a slave device of other routers of the same type.

[0110] As an example, steps S221 to S222 include: when the network port to be tested has been set as a WAN port, the setting result is stored to obtain the WAN port identifier, wherein the WAN port identifier is used to characterize the network port type of the network port to be tested; when it is detected that other physical network ports of the router have access cables, the WAN port identifier is added to the online message of the physical network port of the access cable to characterize that a WAN port already exists in the router, and the physical network port of the access cable is set as a LAN port.

[0111] This application provides a method for adaptively configuring a router's network port. First, the network port to be tested on the router is added to a LAN bridge interface. Then, a probe packet is sent to the network port to be tested through the application layer. The source MAC address of the probe packet is the MAC address of the LAN bridge interface. The application layer then listens to the LAN bridge interface. When the application layer receives a preset reply packet, the network port to be tested is set as a WAN port; otherwise, it is set as a LAN port. This application, by sending probe packets to the network port to be tested at the application layer and receiving reply packets at the application layer, eliminates the need for kernel packet forwarding, reducing code complexity, minimizing resource consumption, avoiding router lag during network port detection, and improving the smoothness of the network port detection process.

[0112] Example 2

[0113] Furthermore, based on the first embodiment of this application, in another embodiment of this application, the same or similar content as in Embodiment 1 can be referred to the above description, and will not be repeated hereafter. Based on this, refer to... Figure 3 The router port adaptive setting method further includes:

[0114] Step B10: When a DHCP discovery message is received, the option field of the DHCP discovery message is checked;

[0115] Step B20: If the option field of the DHCP discovery message is the first preset field, then no reply is given.

[0116] In this embodiment, the first preset field is option 60; the option field is used to identify whether the device connected to the interface under test is a sub-machine, that is, a sub-router in the mesh network, because the sub-router will send a discovery message with the option field SKDETECT, wherein the device receiving the discovery message is the DHCP server in the router.

[0117] As an example, steps B10 to B20 include: when the DHCP server receives a DHCP discovery message, it checks the option field of the DHCP discovery message; if the option field is SKDETECT, it determines that the connected device is a sub-router and does not reply.

[0118] This application provides a router port adaptive setting method. First, when a DHCP discovery message is received, the option field of the DHCP discovery message is checked. If the option field of the DHCP discovery message is a first preset field, no reply is given. This application overcomes the problem in the prior art that, in the network environment of mesh networking, the main router may identify the sub-router as the gateway, thus avoiding the failure situation where the host identifies the mesh sub-machine as the DHCP server, thereby forming a loop and causing all devices to be unable to access the Internet. This improves the identification accuracy of the main router.

[0122] The network port setting module is used to monitor the LAN test bridge interface. When the application layer receives a preset reply message, it sets the network port under test as a WAN port; otherwise, it sets the network port under test as a LAN port.

[0123] Optionally, the message sending module is further configured to:

[0124] When a network cable is detected connected to the network port under test, the kernel transmits the online message of the network port under test to the application layer.

[0125] Based on the online message, determine whether the WAN port already exists;

[0126] If it already exists, then set the network port to be tested as a LAN port;

[0127] If it does not exist, then adaptive settings will be applied to the network port under test.

[0133] Set the layer source MAC address corresponding to both the DHCP discovery message and the PADI message to the MAC address of the LAN bridge interface;

[0134] The transmission sets the destination sending interface corresponding to both the DHCP discovery message and the PADI message to the network port under test;

[0135] Set the option field of the DHCP discovery message to a first preset field, wherein the first preset field is used to characterize the identity of the sending device of the DHCP discovery message;

[0136] The probe message is created based on the message parameters, the DHCP discovery message, and the PADI message.

[0137] Optionally, the network port setting module is further used for:

[0138] Monitor the LAN bridge interface, and when the application layer receives a reply message, determine whether the reply message belongs to the preset reply message;

[0139] If so, disconnect the network port to be tested from the LAN bridge interface and set the network port to be tested as a WAN port;

[0140] If not, then set the network port to be tested as a LAN port.

[0141] Optionally, the network port setting module is further used for:

[0142] Store the setting result of the network port to be tested as a WAN port to obtain the WAN port identifier corresponding to the network port to be tested;

[0144] Optionally, the router port adaptive setting device is further used for:

[0145] When a DHCP discovery message is received, the option field of the DHCP discovery message is checked;

[0146] If the option field of the DHCP discovery message is the first preset field, then no reply will be given.
