All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Fig. 1 is an interactive schematic diagram of an information processing system 10 according to a preferred embodiment of the present invention. The information processing system 10 includes a wireless access point 100 and a wireless controller 200 communicatively coupled to each other. In this embodiment, in the wireless local area network formed by the wireless access points 100 and the wireless controller 200, the wireless controller 200 is a network device, and may control the wireless access points 100 in a centralized manner, and is responsible for managing all the wireless access points 100 in the wireless network, for example, may issue configuration to the wireless access points 100, modify relevant configuration parameters, perform radio frequency intelligent management, perform access security control, and the like.
The wireless access point 100 is an access point for a user to enter a wired network using a terminal (mobile device such as a mobile phone, or wireless device such as a laptop computer), and in some embodiments, the wireless access point 100 may further have an access point client mode (AP client), and may be wirelessly connected to other wireless access points 100 to extend a coverage area of a wireless local area network.
In a local area network, a terminal sends an IP address request to a DHCP server in the network, the DHCP server allocates an IP address in an address pool for the terminal initiating the request, and the terminal can execute corresponding terminal tasks after acquiring the IP address. However, in the current wireless local area network, the terminal often has IP address conflict or cannot acquire the IP address, which causes the terminal service to be interrupted or interrupted, and seriously affects the stability of the terminal service. The inventor of the present application finds that the IP address conflict occurs in the terminal, and in most cases, due to the fact that a plurality of DHCP servers are present or privately arranged in the wireless local area network, and the presence of a plurality of DHCP servers in the network is generally due to a user configuration error or the addition of a DHCP server privately, when the IP address conflict occurs in the terminal, it is difficult to find out which DHCP server is a legal DHCP server.
In order to solve the above problems, the inventor found that, in a discovery process, in an attempt to start a DHCP-snooping function on a switch accessed by the wireless access point 100 and add a DHCP server trust list, when a wireless lan is deployed, the number of switches accessed to the wireless access point 100 is large, configuration workload is large, and operations of changing (for example, adding, deleting, changing the trust list) may often occur in the deployment of the wireless lan, so that related change operations are difficult to develop, configuration errors are very easy to occur, and once configuration errors occur, when multiple DHCP servers occur in a network, a wireless side is difficult to investigate when a terminal cannot acquire an IP.
In view of the above problems, the inventors have conducted long-term research and research to provide an information processing method, apparatus and system to solve the above problems, and in particular, please refer to fig. 2, which is a flowchart illustrating an information processing method according to a preferred embodiment of the present invention, the method is applied to the wireless access point 100 communicatively connected to the wireless controller 200 in fig. 1, and it should be noted that the information processing method according to the embodiment of the present invention is not limited to the specific sequence shown in fig. 2 and described below. The method comprises the following specific steps:
in step S110, the configuration information including the valid DHCP server list is obtained from the radio controller 200.
In this embodiment, the wireless controller 200 is configured with a legal DHCP server list, and when the wireless access point 100 is online, corresponding configuration information is obtained from the wireless controller 200, where the configuration information includes the legal DHCP server list configured in the wireless controller 200. As an implementation manner, the legal DHCP server list may adopt a global setting type, that is, the configured legal DHCP list may be applicable to all the wireless access points 100 accessing the wireless controller 200 and all the wireless servers configured on the wireless access point 100; still alternatively, the list of valid DHCP servers may also be based on service set settings, that is, the configured valid DHCP list is applicable to all wireless access points 100 using the wireless lan service. Of course, in other embodiments, the legal DHCP server list may also be set in multiple types according to needs, and this embodiment does not limit this in detail.
Step S120, detecting whether a DHCP server exists in a local area network where a terminal accessing the wireless access point 100 is located.
In this embodiment, the configuration information may further include configuration options for configuring the wireless access point 100, where the configuration options may include a first configuration option for configuring whether a DHCP server starts legal detection or not, and a second configuration option for configuring a setting type of the legal DHCP server list, where the setting type may include the above global setting type or a setting type based on a service set. In detail, if the first configuration option is to start legal detection, the wireless access point 100 obtains a corresponding legal DHCP server list according to the setting type, so as to probe a DHCP server of the local area network according to the legal DHCP server list.
As an implementation manner, the wireless access point 100 first obtains VLAN information of a local area network (SSID) where a terminal is located, and then sends a DHCP probe message to a VLAN corresponding to the VLAN information, where the DHCP probe message may be used to probe whether a DHCP SERVER exists in a local area network where the terminal accessing the wireless access point 100 is located, so as to form a table similar to SSID- - -VLAN- - -DHCP-SERVER1DHCP-SERVER2, thereby obtaining a probe result.
And step S130, when the detection result is yes, processing the DHCP message according to the configuration information and the detection result.
Specifically, in this embodiment, if the detection result indicates that only one DHCP server exists in the local area network, the DHCP response message sent by the DHCP server or the DHCP request message from the terminal is forwarded regardless of whether the DHCP server is in the valid DHCP server list. And if the detection result represents that at least two DHCP servers exist in the local area network, only forwarding a legal DHCP response message sent by a legal DHCP server in the legal DHCP server list and a DHCP request message sent to the legal DHCP server by the terminal.
Then, the illegal DHCP response message sent by the illegal DHCP server which is not in the legal DHCP server list is discarded, and meanwhile, an alarm message including the illegal DHCP server can be sent to the wireless controller 200 to prompt relevant staff about the condition of the illegal DHCP server in the wireless local area network where the wireless access point 100 is located, so that the abnormal condition of the wireless local area network where the relevant staff is located can be checked, the problem that the illegal DHCP server or the abnormal DHCP server existing in the wireless local area network is difficult to judge when the terminal IP address conflicts occur in the prior art is solved, and the network maintainability and the terminal experience are effectively improved.
In addition, if a valid DHCP server list is not configured in the wireless controller 200, or the configuration information acquired by the wireless access point 100 from the wireless controller 200 does not include the valid DHCP server list, or the configuration information indicates that the wireless access point 100 does not start detection of an IP address of a valid DHCP server, if the wireless access point 100 detects that there are zero or more DHCP servers in the wireless local area network, a corresponding alarm message is sent to the wireless controller 200. If the wireless access point 100 detects that only one DHCP server exists in the wireless lan, the DHCP server is marked as a valid DHCP server, and a DHCP response message sent from the valid DHCP server or a DHCP request message from the terminal can be forwarded, while the DHCP server in the wireless lan is continuously detected.
Based on the above design, by using the characteristic that all data messages sent by the terminal are forwarded through the wireless access point 100, the wireless access point 100 detects the DHCP server in the wireless lan through the configuration information including the legal DHCP server list obtained from the wireless controller 200, thereby realizing the control of the DHCP messages, and solving the problem that the terminal cannot acquire an IP address due to terminal IP address conflict or DHCP server abnormality in the existing wireless lan, and further causing the terminal service to be interrupted or interrupted, thereby effectively improving network maintainability and terminal experience. In addition, by utilizing the feature that the wireless controller 200 can centrally manage the wireless access points 100, the configured valid DHCP server list can be applied to a plurality of wireless access points 100, the configuration workload is small, and the configuration change is easier. When detecting that an illegal DHCP server exists in the current wireless local area network, the wireless access point 100 can send alarm information including the illegal DHCP server to the wireless controller 200 to prompt relevant workers about the condition of the illegal DHCP server in the wireless local area network where the wireless access point 100 is located, so that the abnormal condition of the wireless local area network where the wireless local area network is located can be checked, the problem that the illegal DHCP server or the DHCP server existing in the wireless local area network is difficult to judge abnormally when a terminal IP address conflicts in the prior art is solved, and the network maintainability and the terminal experience are further improved.
Further, referring to fig. 3, after detecting whether a DHCP server exists in a local area network where a terminal accessing the wireless access point 100 is located, the method may further include:
and step S140, if the detection result is negative, sending alarm information to the wireless controller 200.
Further, a readable storage medium is provided in a preferred embodiment of the present invention, and a computer program is stored in the readable storage medium, and when the computer program runs, the computer program controls the wireless access point 100 where the storage medium is located to execute the information processing method.

Further, a readable storage medium is provided in a preferred embodiment of the present invention, and a computer program is stored in the readable storage medium, and when the computer program runs, the wireless controller 200 in which the storage medium is located is controlled to execute the information processing method.
Further, referring to fig. 5, a first information processing apparatus 300 according to a preferred embodiment of the present invention is applied to a wireless access point 100 communicatively connected to a wireless controller 200, wherein the wireless controller 200 is configured with a legal DHCP server list, and the apparatus includes:
