Description
Technical Field
[0001] This application relates to the field of communication technology, and in particular to an address allocation method, apparatus, device, and medium. Background Technology
[0002] In wireless network deployments for small businesses, network architecture simplicity and operational efficiency are core requirements. These scenarios typically rely on gateways (ACs, Access Controllers), access points (APs), and stations (STAs) to build the basic network. The AC needs to simultaneously handle device management and user service support. From a general network planning perspective, to ensure management security and service stability, it is an industry consensus to isolate the management address network segment of network devices (such as APs) from the service address network segment of end users (STAs). The management network segment is used for device configuration, status monitoring, and troubleshooting, while the service network segment is used for user data transmission. This separation reduces the interference of management operations on services and also reduces the risk of external attacks penetrating the device management layer through the service side. As small businesses become increasingly reliant on wireless networks, how to achieve effective isolation of address network segments while simplifying the deployment process has become a pressing practical problem in this field.

However, this solution is suitable for complex deployment scenarios such as medium and large enterprise networks. However, wireless network deployment in small commercial scenarios is characterized by lightweight configuration and rapid implementation.

[0021] To ensure clarity and conciseness in the description of the following embodiments, a brief introduction to the related technologies is given first: In wireless network deployments for small businesses, network architecture simplicity and operational efficiency are core requirements. These scenarios typically rely on gateways (ACs, Access Controllers), access points (APs), and stations (STAs) to build the basic network. The AC needs to simultaneously handle device management and user service support. From a general network planning perspective, to ensure management security and service stability, it is an industry consensus to isolate the management address network segment of network devices (such as APs) from the service address network segment of end users (STAs). The management network segment is used for device configuration, status monitoring, and troubleshooting, while the service network segment is used for user data transmission. This separation reduces the interference of management operations on services and also reduces the risk of external attacks penetrating the device management layer through the service side. As small businesses become increasingly reliant on wireless networks, how to achieve effective isolation of address network segments while simplifying the deployment process has become a pressing practical problem in this field.
[0022] Currently, the mainstream technical solution for separating management address and service address network segments is based on virtual LAN partitioning. That is, different virtual LAN identifiers are assigned to device management services and user data services through network configuration. However, this solution is suitable for complex deployment scenarios such as medium and large enterprise networks. However, wireless network deployment in small commercial scenarios is characterized by lightweight configuration and rapid implementation. Consequently, address segment separation schemes based on virtual LANs have poor adaptability in small commercial scenarios and cannot achieve accurate separation of address allocation.
[0023] To make the technical solution of this application clearer and easier to understand, the application scenarios of the technical solution of this application are described below with reference to the accompanying drawings. Figure 1 As shown in the figure, this figure is a schematic diagram of an application scenario provided by an embodiment of this application.
[0024] In this application scenario, both AP device 102 and STA device 103 initiate DHCP address requests through UDP port 67 and complete the address allocation through interaction with AC device 104.
[0025] To make the technical solution of this application clearer and easier to understand, the following describes an address allocation method provided by an embodiment of this application, taking the access controller AC device 104 as an example, in conjunction with the above application scenario. Figure 2 As shown, this figure is a flowchart of an address allocation method provided in an embodiment of this application.
[0026] S201. Upon receiving the first message sent by the first device from the first port, reply to the first device with a second message through the second port.
[0027] The first message is a Dynamic Host Configuration Protocol (DHCP) Discover message, i.e., DHCP Discover; the second message is a DHCP Offer message, i.e., DHCP Offer, which includes a first assigned address and a preset field identifier.
[0028] Optionally, the first port is UDP port 67; the second port is UDP port 68; the default field identifier can be DHCP Option 234.
[0029] For example, when the first device is powered on and has not yet obtained an IP address, the DHCP client is started by default. It broadcasts the first message DHCP Discover (which is automatically triggered when network access is needed, and is usually sent once per minute until a response is received) through the first port (UDP 67, the standard DHCP client sending port). The message content is "Request IP address allocation". AC listens on UDP port 67 and captures the DHCP Discover message (i.e., the first message) sent by the first device. Then, AC's DHCP server1 (service address pool server) allocates a first allocation address from the service address pool, adds a preset field identifier (Option 234) to the message, generates a second message (DHCP Offer), and sends the second message to the first device through the second port (UDP 68, the standard DHCP server reply port).
[0030] It should be noted that the AC device, or Access Controller, is responsible for managing AP devices and address allocation; the DHCP client is the Dynamic Host Configuration Protocol client module built into the device (such as the AP device); the DHCP Discover message is the first message in the DHCP protocol process, broadcast by the client to find a DHCP server; the DHCP Offer message is the second message in the DHCP protocol process, sent by the server to the client, including information such as the assigned IP address.
[0031] S202. If the first device is a wireless access point (AP) device, upon receiving the third message sent by the first device from the third port and the first device receiving the second message, the first device replies with a fourth message through the fourth port to allocate an address to the first device.
[0032] The third message is a DHCP discovery message; the fourth message is a DHCP offer message that includes the second assigned address.
[0033] Optionally, the third port is UDP port 6767; the fourth port is UDP port 6768.
[0034] Furthermore, a Message Queuing Telemetry Transport Protocol (MQTT) connection can be established with the AP device based on the second allocated address; management information can be sent to the AP device based on the MQTT connection; the management information includes configuration information, status information, and detection information.
[0035] Optionally, if the first device is a workstation (STA) device, the first assigned address is used as the address of the first device so that the STA device can access the wireless network.
[0036] For example, after receiving the second message (containing Option 234), the AP device first completes the standard DHCP process (responding to the AC device with a request message, receiving an acknowledgment message, and obtaining the first assigned address). Then, upon resolving the Option 234 identifier, it automatically modifies its own DHCP client configuration: changing the sending port to the third port (UDP 6767, a custom management port) and the receiving port to the fourth port (UDP 6768, a custom management port), and restarts the DHCP client process (the restarted DHCP client sends messages through the third port). After the AP device resolves the Option 234 identifier in the second message, the AP device sends a third message (DHCP Discover) through the third port (UDP 6767). At this time, the message target is the AC device's management address pool server (dhcp server2). The AC device's DHCP server2 listens on UDP port 6767 and captures the third packet sent by the AP device. DHCP server2 allocates a second allocation address (AP-specific management IP) from the management address pool. After the AC device generates a fourth packet (DHCP Offer), it sends the fourth packet to the AP device through the fourth port (UDP 6768). Furthermore, after receiving the fourth message, the AP device replies with a DHCP request message to the AC device, and finally receives the acknowledgment message (ACK) sent by the AC device, thus completing the acquisition of the second allocated address. Based on the second allocated address, it establishes an MQTT (Message Queuing Telemetry Transport) connection with the AC device, so that the AC device can send management information through MQTT, realizing centralized management of the AP device by the AC device, and completing the wireless network deployment without manual configuration.
[0037] Optionally, management information may include, but is not limited to, configuration information, status information, and detection information; configuration information: such as deployment parameters such as wireless network name, encryption method, and working channel; status information: such as global data such as the current load of the AC device and the operating status of other AP devices; detection information: such as link connectivity detection and AP device hardware status (temperature, signal strength) query commands.
[0038] If the first device is a STA device, after receiving the second message (containing the first allocated address, but the STA device does not recognize the Option 234 identifier), the STA device directly completes the subsequent DHCP process (responding to the request message and receiving the confirmation message). The AC device directly uses the first allocated address as the final service address of the STA device. That is, the STA device uses the first allocated address to access the wireless network and only uses it for service needs such as accessing the Internet. There is no need to establish a management connection with the AC device.
[0039] The aforementioned address allocation method, upon receiving a first message from a first device via a first port, replies to the first device via a second port with a second message including a first allocated address and a preset field identifier. If the first device is a wireless access point (AP), upon receiving a third message from a third port and the first device receiving the second message, replies to the first device via a fourth port with a fourth message including a second allocated address, thereby allocating an address to the first device. This solution, by introducing a preset field identifier, provides a method for targeted address allocation to AP devices, distinguishing AP devices from other STA devices through address allocation and achieving precise separation of address allocation.
[0040] Taking a wireless access point (AP) device 102 as an example, an address allocation method provided in this application embodiment will be described. For example... Figure 3 As shown, this figure is a flowchart of an address allocation method provided in an embodiment of this application: S301. Based on the first port, send the first message to the access controller AC device.
[0041] The first message is a Dynamic Host Configuration Protocol (DHCP) discovery message.
[0042] For example, when an AP device is first powered on and has not yet obtained any IP address, it needs to connect to the network and establish a connection with the AC device. The AP device will automatically start its built-in DHCP client, enter the address request state, and use the first port (UDP 67, the standard DHCP client sending port) as the message sending channel by default. It sends the first message (DHCP discovery message) in broadcast form. The message content includes basic information such as the AP device's device identifier, and the core request is "to request the AC device to assign an IP address". If no reply is received from the AC device, the AP device will resend once every minute until a response is obtained. Furthermore, the AC device's dhcp server1 (service address pool server) listens on UDP port 67 by default, which can capture the first message and prepare subsequent replies.
[0043] S302. Upon receiving a second message from the AC device and recognizing that the second message includes a preset field identifier, a third message is sent to the AC device via the third port.
[0044] The second message is a DHCP offer message that includes the first assigned address and a preset field identifier; the third message is a DHCP discovery message.
[0045] Optionally, after recognizing that the second message includes a preset field identifier, modify the Dynamic Host Configuration Protocol (DHCP) client configuration file, update the message sending port to the third port and the receiving port to the fourth port, and restart the DHCP client process.
[0046] For example, after the AC device (DHCP server1 is running) captures the first packet, it allocates the first allocation address from the service address pool, adds a preset field identifier (Option 234) to the reply second packet (DHCP provide packet), and sends it to the AP device through UDP port 68; After receiving the second message from the AC device via the default receive port (UDP 68), the AP device extracts the first allocated address from the message and recognizes the preset field identifier (Option 234) in the message. Then, the AP device uses the Option 234 identifier to confirm the AP device's modified configuration and restarts the DHCP client. Specifically, it edits its own DHCP client configuration file, updating the original "message sending port" from the first port (UDP 67) to the third port (UDP 6767) and the "message receiving port" to the fourth port (UDP 6768). After saving the configuration file, it restarts the DHCP client process to make the new port configuration take effect. Then, the AP device (with the DHCP client restarted) uses the updated third port (UDP 6767) to send a third message (DHCP discovery message) in broadcast form. At this time, the message target is clearly directed to the AC's management address pool server (dhcpserver2).
[0047] S303. Upon receiving the fourth message from the AC device, establish a Message Queuing Telemetry Transport Protocol (MQTT) connection with the AC device based on the second allocated address in the fourth message.
[0048] The fourth message is a DHCP offer message that includes the second assigned address.
[0049] For example, if the AC device has enabled dhcp server2 (management address pool server) and the server is listening on the third port (UDP 6767), after dhcp server2 captures the third packet sent by the AP device from the third port, it allocates a unique second allocation address (AP device exclusive management IP) from the management address pool, generates a fourth packet (DHCP provide packet) including the second allocation address, and sends it to the AP device through the fourth port (UDP 6768); After receiving the fourth message through the fourth port, the AP device extracts the second allocated address and completes the subsequent DHCP process (responding to the AC device with a request message and receiving an acknowledgment message). Finally, it configures the address as its own management IP and uses the second allocated address (management IP) as a communication identifier to actively establish an MQTT connection with the AC device (a lightweight IoT link adapted to low-bandwidth communication needs between devices).
[0050] In this embodiment, a first message is sent to the access controller (AC) device via a first port; upon receiving a second message from the AC device and recognizing that the second message includes a first allocated address and a preset field identifier, a third message is sent to the AC device via a third port; upon receiving a fourth message from the AC device including a second allocated address, a Message Queuing Telemetry Transport Protocol (MQTT) connection is established with the AC device based on the second allocated address in the fourth message. This solution, by introducing a preset field identifier, provides a way for the AC device to allocate addresses to AP devices and other STA devices in a targeted manner, achieving precise separation of address allocation.
