and step S15, carrying out RU subchannel allocation on the client according to the traffic mode corresponding to the client and the RU subchannel groups after the priority sorting.
It should be noted that, different types of clients generate different traffic demands in different application scenarios, for example, the traffic required in the application scenarios such as video, web browsing, game, etc. is different, the network device pre-establishes a traffic model group table classified based on the traffic demand of the client, the traffic model group table includes a plurality of traffic modes, each traffic mode corresponds to a traffic demand, and the network device also establishes a RU rate packet table in advance, the RU rate packet table includes a plurality of RU subchannel packets, each RU subchannel packet corresponds to an actual traffic rate, each actual traffic rate corresponds to a traffic demand, each actual traffic rate corresponds to a traffic pattern in the traffic model packet table, that is, the traffic patterns in the traffic model packet table have a one-to-one correspondence with the RU subchannel packets in the RU rate packet table.
In specific implementation, the network device obtains the current traffic demand of each client connected to the network device every preset time period (the specific time period can be set according to actual demands), matching the flow mode corresponding to each client according to the current flow demand of each client and the flow model grouping table, when the traffic mode corresponding to any one client is inconsistent with the current traffic mode corresponding to the RU sub-channel group currently used by the client, detecting the interference signal strength in all RU sub-channels of the network equipment, and prioritizes all of the RU subchannel packets in the RU rate packet table based on the interference signal strength in each RU subchannel, and then the RU subchannel allocation is carried out on the client according to the traffic mode corresponding to the client and the RU subchannel packet after the priority sorting.

In addition, the IEEE 802.11ax protocol defines related concepts of RU only in the physical layer and the MAC layer, and the allocation of RU subchannels is randomly allocated based on the signal quality of the physical layer and the MAC layer and does not rise to the application layer level.
In another preferred embodiment, the acquiring the current traffic demand of each client connected to the network device at preset time intervals specifically includes:
counting the flow rate and the data packet length corresponding to each client connected with the network equipment at intervals of a preset time period;
and acquiring the current flow demand of each client according to the flow rate and the data packet length corresponding to each client.
Specifically, with reference to the above embodiments, the traffic rate and the frame length of the data frames of different types of clients in different application scenarios have particularity, which may be used as a classification and differentiation standard, after the clients access the network device, the network device may record the unique MAC address of each client, and at intervals of a preset time period, the network device detects and counts data such as the traffic rate and the packet length (including but not limited to the traffic rate and the packet length) corresponding to each client connected to the network device through upper layer software, so as to determine the client type and the application scenario of each client according to the data such as the traffic rate and the packet length corresponding to each client obtained through statistics, and further determine the current traffic demand of each client.
It should be noted that, because the application scenario of the client may change during the working process, and the corresponding traffic demand may also change, the current traffic demand of the client needs to be counted at regular time intervals to determine whether to reallocate the RU sub-channel currently used by the client.
In yet another preferred embodiment, the method further comprises:

It should be noted that the traffic demand of the client may be a traffic range, and if the current traffic demand range of the client exceeds the traffic demand range corresponding to the current traffic mode of the client, it indicates that the traffic mode corresponding to the client is inconsistent with the current traffic mode of the client.
In another preferred embodiment, the prioritizing the RU subchannel packets in the preset RU rate packet table according to the interference signal strength specifically includes:
and according to the sequence of the strength of the interference signal from small to large, the RU subchannel packets in the RU rate packet table are arranged according to the sequence of the priority from high to low.
Specifically, with reference to the foregoing embodiment, after obtaining the strength of the interference signal in all the RU subchannels, the network device arranges all the RU subchannel packets in the RU rate packet table in the order from high priority to low priority according to the order from low interference signal strength in each RU subchannel to high interference signal strength, and when allocating an RU subchannel to a client, the RU subchannel having a high priority and a low interference signal strength may be allocated to the client corresponding to a traffic pattern with a high traffic demand.
As an improvement of the above scheme, the traffic modes in the traffic model grouping table are divided according to the application scenarios of the client; the application scenario corresponds to the traffic rate requirement, the data frame length, the data type and the channel quality requirement of the client in the communication process.
Specifically, in combination with the above embodiments, different types of clients generate different traffic demands in different application scenarios, and corresponding traffic patterns are different, so that the traffic patterns may be grouped according to the application scenarios (the application scenarios correspond to the data types) of the clients, and the traffic patterns, the traffic rate demands, the data frame lengths, the data types, and the channel quality needs have a one-to-one correspondence relationship.
Preferably, the application scenarios at least include file transfer, network voice call, network video playing, network game and network monitoring.
It can be understood that the application scenarios include, but are not limited to, file transfer, network voice call, network video playing, network game, and network monitoring, and are applicable to any network communication service that may exist in the wireless client.
As an improvement of the above scheme, the RU subchannel blocks in the RU rate block table are divided according to the bandwidth and frequency of the RU subchannel; the bandwidth and the frequency correspond to the actual traffic rate, respectively.
Specifically, in combination with the above embodiments, the RU rate grouping table indicates the actual throughput that can be obtained by the client under different RU subchannel bandwidths, and is a one-to-one correspondence relationship between the actual traffic rate and the RU subchannel bandwidth, and the RU subchannel bandwidths corresponding to different actual traffic rates are the same, but the frequencies may be different, so that there are multiple RU subchannel grouping modes, that is, RU subchannels can be grouped according to the bandwidth and the frequencies of the RU subchannels.
The actual traffic rate in the RU rate packet table has a one-to-one correspondence with the traffic rate requirement in the traffic model packet table, and in a specific rate value, the actual traffic rate is greater than or equal to the corresponding traffic rate requirement, so that the allocated RU subchannel satisfies the traffic requirement of the corresponding client.
It should be noted that, at present, the RU subchannels in the IEEE 802.11ax protocol share several atomic bandwidths, such as RU-26, RU-52, RU-106, RU-242, RU-484, and RU-996, the maximum actual traffic rate that each RU subchannel can support is different, and in a complete channel (specifically, in various cases, such as 20MHz, 40MHz, 80MHz, and 160MHz channels), the several RU subchannels can be grouped differently according to frequency without exceeding the bandwidth limit.
For example, for the RU-26 subchannels, there are 9 RU-26 subchannels with different frequencies in the 20MHz channel, that is, RU 0-RU 8, which correspond to different interference situations, respectively, and then the RU-26 subchannels with different frequencies can be selected to be allocated to the client according to actual needs and in combination with the interference situations.
In the practical application process, assuming that a client is in three application scenes of document printing, high-definition television and video telephone, corresponding to three traffic modes respectively, firstly selecting the bandwidth of an RU subchannel according to the traffic mode, and then selecting RU subchannel groups corresponding to different frequencies according to the interference degree of the RU subchannel, wherein, for document printing, only the RU-26 bandwidth is needed to meet the requirement, and in combination with the above, the RU-26 bandwidth has 9 RU-26 subchannels of different frequencies, namely RU 0-RU 8, assuming that the interference signal strength is ordered as RU0> RU8> RU7 RU > 6 ═ RU5> RU4> RU3> RU2> RU1, and the document printing traffic requirement is low, the RU-26 subchannel groups with large interference (such as RU0, RU8 and RU7) can be allocated to the application scene, and the RU-106 bandwidth needs to be allocated for high-definition television and video telephone, high definition television and video telephony traffic demands are high and RU subchannel packets with less interference in the RU-106 bandwidth can be allocated to both application scenarios.
