Those skilled in the art will appreciate that the terminal structure shown in fig. 1 does not constitute a limitation of the terminal device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a computer-readable storage medium, may include an operating system, a network communication module, a user interface module, and a wireless message capture program.
In the terminal shown in fig. 1, the network interface 1004 is mainly used for connecting to a backend server and performing data communication with the backend server; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to invoke the wireless message capture program stored in the memory 1005 and perform the following operations:
determining wireless Mesh networking;
determining a capturing mode of the wireless message according to the wireless Mesh networking;
and executing the wireless message grabbing operation on all wireless nodes in the wireless Mesh network according to the grabbing mode to obtain the wireless messages of all the wireless nodes.
Referring to fig. 2, fig. 2 is a schematic flowchart of a first embodiment of a wireless packet capturing method according to the present application, where the wireless packet capturing method includes:
step S10, determining wireless Mesh networking;
in this embodiment, the wireless Mesh is a wireless network structure with multiple hops, automatic backhaul and automatic networking, and has the characteristics of strong mobility, strong survivability, flexible networking mode and the like, and no dead-angle coverage can be achieved in a family through wireless Mesh networking WiFi signals.
The wireless Mesh networking includes various types, and the modes for capturing the wireless messages are different based on the difference of the wireless Mesh networking, so that the wireless Mesh networking needs to be determined before the capturing mode of the wireless messages is determined. The wireless Mesh networking needs to comprehensively consider factors such as channel interference, hop selection, frequency selection and the like, and taking 802.11s WLAN Mesh as an example, the networking can be divided into single-frequency networking and double-frequency networking; when a single-frequency networking is used, the access and return of all the wireless access points Mesh AP and the wired access points RootAP work in the same frequency band, for example, the access and return can be carried out by adopting a channel 802.11b/g on 2.4 GHz; when dual-frequency networking is used, the backhaul and access of each node both use two different frequency bands, for example, a 2.4GHz 802.1l b/g channel is used for local access service, and a 5.8GHz 802.11a channel is used for a backbone Mesh backhaul network, which do not interfere with each other.
Based on the difference between the networking topology and the networking frequency band in the wireless Mesh network, the wireless Mesh networking is also different, and therefore, referring to fig. 6, the step of determining the wireless Mesh networking includes:
step S11, each wireless node in the wireless Mesh network is respectively arranged in different shielding boxes, and wireless links are adjusted through the shielding boxes to form different networking topologies;
and step S12, executing networking operation on the networking topology through different networking frequency bands to obtain various different wireless Mesh networking.
The networking topology types of the wireless Mesh distributed system comprise a linear topology, a star topology, a ring topology and the like, when the wireless Mesh distributed system is tested in a laboratory, a master AP and a slave AP need to be placed in different shielding boxes, wherein the AP refers to an access point, is used for a wireless switch of the wireless network and is also the core of the wireless network; the wireless links are adjusted to form various networking topologies by adjustable attenuation between the shielded boxes, for example: taking the star wireless Mesh networking topology as an example, the attenuation of the master AP and the slave AP1 and 2 is 30dB, and the attenuation between the slave AP1 and the slave AP2 is 90dB, i.e. the wireless Mesh will automatically form the star Mesh topology. Single-frequency networking and dual-frequency networking are in turn divided among various networking topologies, such as: the networking topology comprises modes of networking in a 2.4GHz frequency band, networking in a 5GHz frequency band, comprehensive networking in 2.4GHz and 5GHz and the like, the networking topology performs networking operation through different networking frequency bands to obtain various different wireless Mesh networking, for example, the star topology can obtain one wireless Mesh networking by adopting the networking in the 2.4GHz frequency band, or the star topology can obtain another wireless Mesh networking by adopting the networking in the 5GHz frequency band.
Step S20, determining the capturing mode of the wireless message according to the wireless Mesh networking;
in this embodiment, the message is a data unit exchanged and transmitted in the network, that is, a data block to be sent by a station at a time, and the message includes complete data information to be sent, and the length of the message is very different and is not limited and can be changed. Determining a capture mode of a wireless message based on wireless Mesh networking, specifically determining the capture mode of the wireless message according to different networking topologies and networking frequency bands in a wireless Mesh network, for example, if the current networking topology is a star topology, networking is performed by adopting a 2.4GHz frequency band, the capture mode is a mode of using a single packet capture module to cooperate with a splitter; or the current networking topology is linear topology, and networking is carried out by adopting a 5GHz frequency band, and the capturing mode is a mode of using a single packet capturing module to be matched with a splitter or a mode of integrating a plurality of packet capturing modules to capture packets synchronously; or the current networking topology is a ring topology, and 2.4GHz and 5GHz integrated networking is adopted, so that the capturing mode is a mode of integrating a plurality of packet capturing modules to capture packets synchronously. When different networking topologies adopt single-frequency networking, the capturing mode is a mode of using a single packet capturing module to match with a splitter or a mode of integrating a plurality of packet capturing modules to capture packets synchronously; when different networking topologies adopt dual-frequency networking, the capturing mode is a mode of integrating a plurality of packet capturing modules to capture packets synchronously.
And step S30, executing the grabbing operation of the wireless messages to all the wireless nodes in the wireless Mesh network according to the grabbing mode to obtain the wireless messages of all the wireless nodes.
When the user uses wifi, the problems of frequent disconnection, unstable communication, slow network speed, message interruption and the like are likely to occur, and when the user solves the wifi problems, the user needs to capture wireless messages to analyze and diagnose the root cause of the problems under some conditions.
And (3) performing wireless message capturing on all wireless nodes in the wireless Mesh network by using a wireless network card and a wireless message capturing tool, such as a wireshark or a tcpdump. Specifically, before capturing a wireless packet transmitted on a target channel, a terminal device may first obtain the target channel to be captured of the wireless packet, and since a working channel during operation of a communication network is usually fixed, when a wireless packet in the communication network needs to be captured, the target channel to be captured by the terminal device may be set as the working channel where the communication network is located. It can be understood that after acquiring the working channel used by the field communication network, the terminal device may capture all wireless packets transmitted on the channel, where the captured wireless packets include all wireless packets transmitted between node devices in the communication network, that is, wireless packets of all wireless nodes in the wireless Mesh network are captured.
Optionally, a technician may determine a problem existing in the wireless Mesh network by performing problem analysis on the captured wireless packet; since the acquired wireless messages are of various types, such as UDP-type wireless messages, IGMP-type wireless messages, TCP-type wireless messages, and the like, before the problem analysis operation of the messages is performed, the captured messages are filtered through a preset filtering condition to obtain messages required for analysis, where the preset filtering condition is that only UDP-type messages are required or only IGMP-type messages are required. Specifically, when the filtering condition is that only UDP type wireless messages are needed, a BPF filter corresponding to the filtering condition is called, the filter first parses each received wireless message, then obtains the parsed protocol field, determines whether the message is a UDP packet according to whether the value of the protocol field is equal to 17, if the value of the protocol field is equal to 17, the message is a UDP packet, and needs to be retained, otherwise, the message is discarded. Further, the wireless message obtained by the filtering condition is subjected to a wireless interaction process through an analysis module, the wireless interaction process is a normal wireless interaction process of shared key authentication, and meanwhile, problems existing in the wireless Mesh network are analyzed, such as frequent disconnection, unstable communication, slow network speed and the like, so that the reason of the problems is found out, and corresponding optimization operation is executed.
In this embodiment, wireless Mesh networking is determined first, a wireless message capturing mode is determined based on the wireless Mesh networking, and capturing operations of all wireless nodes in the wireless Mesh network are executed according to the capturing mode to obtain wireless messages of all wireless nodes, so that wireless message capturing can be performed on a plurality of master-slave APs and terminals in a wireless Mesh distributed system at the same time.
In an embodiment, referring to fig. 3, the step of determining a capturing manner of the wireless packet according to the wireless Mesh networking includes:
step S21, determining networking frequency bands adopted by a master AP and a plurality of slave APs in the wireless Mesh network;
and step S22, determining the capturing mode of the wireless message based on the networking frequency band.
Confirm the main AP in the wireless Mesh network and a plurality of network deployment frequency channels that adopt from the AP network deployment, the network deployment frequency channel includes 2.4GHz and 5GHz etc. based on the difference of network deployment frequency channel, can divide into single-frequency network deployment or dual-frenquency network deployment, single-frequency network deployment is main AP and a plurality of follow AP use single frequency channel to carry out the network deployment promptly, if 2.4GHz or 5GHz, dual-frenquency network deployment is AP and a plurality of follow AP use two different frequency channels to carry out the network deployment promptly, if 2.4GHz and 5 GHz. Determining the capturing mode of the wireless packet based on the difference of the networking frequency bands, and therefore, referring to fig. 7, the step of determining the capturing mode of the wireless packet based on the networking frequency bands includes:
step S220, if single-frequency networking is adopted between a master AP and a plurality of slave APs in the wireless Mesh network, the capturing mode of the wireless message is a mode of using a single packet capturing module to cooperate with a splitter and/or a mode of integrating a plurality of packet capturing modules to capture packets synchronously;
step S221, if the dual-frequency networking is adopted between the master AP and the multiple slave APs in the wireless Mesh network, the capturing mode of the wireless message is a mode of synchronously capturing packets by integrating multiple packet capturing modules.
In this embodiment, if a single-frequency networking is adopted between a master AP and multiple slave APs in a wireless Mesh network, the capturing mode of a wireless packet is a mode of using a single packet capturing module in cooperation with a splitter, and/or a mode of integrating multiple packet capturing modules to capture a packet synchronously, for example: if 2.4GHz is adopted before the master AP and the slave AP1, and 2.4GHz networking is also adopted before the master AP and the slave AP2, or networking is carried out between the master AP and the slave AP1 and the AP2 through a 5GHz frequency band, a packet capturing mode of a single packet capturing module matched with a splitter is used, or a mode of synchronously capturing packets by integrating a plurality of packet capturing modules is used; if dual-frequency networking is adopted between the master AP and the multiple slave APs in the wireless Mesh network, the capturing mode of the wireless message is a mode of integrating multiple packet capturing modules to capture packets synchronously, for example: if the master AP and the slave AP1 adopt 2.4GHz before and the master AP and the slave AP2 adopt 5GHz networking before, a mode of synchronously grabbing packets by integrating a plurality of packet grabbing modules is used.
In this embodiment, by determining networking frequency bands adopted by networking the master AP and the plurality of slave APs in the wireless Mesh network, the capturing mode of the wireless packet can be determined based on the networking frequency bands.
In an embodiment, referring to fig. 4, after the step of using the single packet capturing module in cooperation with the splitter, the method for capturing the wireless packet includes:
step S222, respectively introducing the radio frequency channel of the single packet capturing module into a shielding box of each wireless node through a splitter;
and step S223, executing the grabbing operation of the wireless message to the wireless node in the shielding box through the single packet grabbing module.
In this embodiment, when a single packet capturing module is used in conjunction with a packet capturing mode of a splitter, a radio frequency channel of the single packet capturing module is respectively introduced into a shielding box of each wireless node through the splitter, the splitter can separate multiple frequency band signals input on a line in a wireless communication system into a single frequency band and output the single frequency band signal to different communication lines, and in the field of communication, the splitter is a device for separating a telephone channel from a data channel; and the single packet capturing module is used for performing the capturing operation of the wireless message on the wireless nodes in the shielding box, namely capturing the wireless message within the range of each wireless node. The wireless messages captured by the single-module packet capturing module do not need to be subjected to timestamp synchronization, and the wireless messages are captured according to the time sequence when the packets are captured because only one packet capturing module is provided.
In this embodiment, a single packet capturing module is used in cooperation with a splitter to capture wireless packets in the wireless Mesh network, so that the wireless packets of all wireless nodes in the wireless Mesh network can be captured simultaneously.
In an embodiment, referring to fig. 5, after the step of integrating the multiple packet capturing modules to capture the packet synchronously, the method for capturing the wireless packet includes:
step S224, respectively introducing the radio frequency channel of each packet capturing module into the shielding box of the corresponding wireless node, wherein one packet capturing module is introduced into the shielding box of one wireless node;
and step S225, executing the grabbing operation of the wireless message to the wireless nodes in the shielding box through each packet grabbing module.
In this embodiment, when a mode of synchronously grabbing packets by integrating a plurality of packet grabbing modules is used, the radio frequency channel of each packet grabbing module is respectively introduced into the shielding boxes of the corresponding wireless nodes, wherein one packet grabbing module is introduced into the shielding box of one wireless node, that is, the packet grabbing module and the wireless node are in a one-to-one correspondence relationship, and then the wireless nodes in the shielding boxes are respectively grabbed by the packet grabbing modules.
Further, referring to fig. 8, after the step of respectively introducing the radio frequency channel of each packet capturing module into the shielding box of the corresponding wireless node, the method includes:
step S226, acquiring an operation command for capturing the wireless message, and executing the capturing operation of the wireless message of each packet capturing module based on the operation command;
and step S227, performing associated storage on the wireless message captured by each packet capturing module and a timestamp, wherein the timestamp is a time point for capturing the wireless message.
Before executing a wireless message capturing operation, each packet capturing module needs to acquire an operation command for capturing a wireless message, and based on the operation command, the capturing operation of the wireless message of each packet capturing module is executed, for example: first, a promiscuous mode (sniffer mode) of a wireless network card (for example, a Wi-Fi module) in the terminal needs to be activated, so that the promiscuous mode of the wireless network card becomes available for the user to control. And meanwhile, a corresponding user interface is created, and an opening/closing control is arranged on the user interface, so that a user can control the opening or closing of the hybrid mode by triggering the opening/closing control. When the terminal detects the triggering operation of the user touch control opening/closing control, an operation command for capturing the wireless message is generated, and the operation of capturing the wireless message by each packet capturing module is executed based on the operation command.
In order to facilitate technicians to find wireless messages required to be analyzed in time, the wireless messages and timestamps can be stored in an associated manner, wherein the timestamps are time points for capturing the wireless messages; specifically, the wireless message may be stored in a local file according to a specific format (e.g., pcap file format), and the file is named by a timestamp, so as to implement the associated storage of the wireless message and the timestamp. Therefore, when network communication or equipment operation fails, wireless messages before and after the failure time can be directly inquired according to the failure occurrence time and the stored timestamp, and therefore problem tracing, problem analysis and problem positioning are carried out on a failure site. Optionally, timestamp synchronization may be performed on the wireless messages, and then the wireless messages with the timestamp synchronization are stored, where the timestamp synchronization refers to sequencing the wireless messages captured by all the packet capturing modules according to a time sequence, so as to form an integral message. The time stamp synchronization is mainly performed to facilitate analyzing the roaming behavior of the packet, for example: when the STA is analyzed to roam among different AP nodes, the roaming behavior can be analyzed through messages arranged according to the time sequence.
Optionally, the wireless messages captured by each packet capturing module may be further marked, for example, a tag is used for marking, the tag is defined by the user, is more accurate and more specific than classification, and can summarize keywords of main contents of an article, and a technician can more conveniently and accurately find a desired wireless message by marking the wireless message with the tag.
In this embodiment, the wireless packets in the wireless Mesh network are captured by integrating a plurality of packet capturing modules, so that the wireless packets of all wireless nodes in the wireless Mesh network can be captured simultaneously, and meanwhile, the wireless packets and the timestamps are stored in an associated manner, and then a wireless interaction process and problem analysis are performed, so that the problems existing in the wireless Mesh network can be determined, and the existing problems are optimized.

the second determining module is further configured to, if dual-frequency networking is adopted between the master AP and the multiple slave APs in the wireless Mesh network, adopt a mode of capturing the wireless packet to be a mode of synchronously capturing the packet by integrating the multiple packet capturing modules.
Further, the second determination module comprises an introduction unit and a grabbing unit;
the introducing unit is used for introducing the radio frequency channel of the single packet grabbing module into the shielding box of each wireless node through a splitter respectively;
and the grabbing unit is used for carrying out grabbing operation of the wireless message on the wireless node in the shielding box through the single grabbing module.
