Technical Field
The invention relates to the technical field of communication, in particular to a wireless speed limiting method and system based on wlan.
Background
With the rapid development of wireless communication network technology and the rapid growth of service expansion, the available spectrum resources are increasingly scarce. With the evolution of the 802.11 protocol, the channel has been extended from the original 20Mb to 40Mb, 80Mb, 120Mb, and these large bandwidths are formed by several 20Mb bonding, for example, 40Mb is formed by two 20Mb bonding, one 20Mb is the main channel, and the other is the auxiliary channel. If one AP works on the first channel and works with the bandwidth of 20Mb/40Mb, and the other AP works on the first channel and works with the bandwidth of 20Mb/40Mb/80Mb, the probability of collision between the AP and the STA in large-bandwidth transmission is increased, and the efficiency of large-bandwidth transmission is reduced.

The current general technical scheme in the market has a large loophole in that the corresponding adjustment of the air interface environment and the actual message service is lacked, and the effectiveness and the reasonability of the speed limit are lacked with better evaluation.

for example:
in the dormitory scene of school, the time of giving lessons at night, the network peak period stage, a large amount of students use the following network, in the whole network environment, respectively contain two following subnetwork environments:
under AP 2.4G radio frequency environment: 13 users, 6 channels, HT20 (channel bandwidth 20 Mb);
in AP 5G radio frequency environment: 32 users, 149 channels, HT20 (channel bandwidth 20 Mb); the QOS speed limit of the terminal is 2 Mb;
in a practical scenario, an initial speed limit configuration is generally made based on the wlan, for example: an initial speed limit value of 0.25Mb is configured under the AP 2.4G radio frequency environment, an initial speed limit value of 2Mb is configured under the AP 5G radio frequency environment, the speed limit of all equipment is fixed under the initial condition, the quantity of users in the environment where some APs are located is less than that of the clean users, the quantity of users in the environment where some APs are located is large in interference, in this case, the speed limit adjustment needs to be performed again, and in the AP 2.4G radio frequency environment, the speed limit adjustment needs to be performed once based on air interface load identification speed limit, for the whole network environment, the sub-network AP 2.4G rf environment and the sub-network AP 5G rf environment are required to be able to identify based on the environment and user situation, meanwhile, different devices can also make judgment and identification based on the bearing capacity of the devices, so that the device load speed limit needs to be carried out again on the basis of the air interface load identification speed limit.
For each sub-network environment in the whole network environment, respectively carrying out air interface load identification speed limitation on the sub-network environment according with the air interface load identification speed limitation condition of the wireless access point AP equipment, and acquiring a total speed requirement value after the air interface speed limitation under the sub-network environment;
under AP 2.4G radio frequency environment: obtaining 13 current users of the radio frequency band corresponding to the air interface through wlc _ ap _ stas _ associated function; determining the basic rate requirement value of each terminal to be 2Mb according to the number of the current users and the basic traffic that each user should allocate, assuming that 25Mb of traffic quota is corresponding to the current empty port corresponding to 2.4GHT20 when the current empty port is fully loaded, in this embodiment, 30% of traffic percentage corresponding to the empty load quota of the empty port is determined, 30% of traffic percentage is used to determine the traffic threshold corresponding to the empty load quota,
2Mb 13>25Mb 30%, namely, the triggering air interface at the moment identifies the speed limit; at this time, 10% of the load is reserved as the spare load of the CPU, namely the load saved by the air interface;
in this embodiment, based on the above-mentioned empty identification speed limit, the channel utilization rate is considered to be 60% under the normal use condition, and then the allocable total flow rate of the speed limit is determined to be 25Mb by 60% according to the flow threshold corresponding to the empty load quota, which is 15 Mb; corresponding to the dynamic speed limit value of the air gap, namely 25Mb, 60%/13, 1.15 Mb;
when there are 13 users in the radio frequency 2.4G environment, identifying the speed limit based on the air interface, wherein the corresponding speed limit value is 25Mb by 60%/13 to 1.15 Mb;
then, the total rate requirement value after air interface speed limiting in the sub-network radio frequency 2.4G environment is 1.15Mb by 13 users, which is 14.95 Mb;

under the sub-network radio frequency 5g environment, 32 users exist, and the determined terminal QOS limits the speed by 2 Mb;
then, in the sub-network rf 5g environment, the total rate requirement value is 2Mb × 32 users — 64 Mb;
acquiring a total speed required value under the whole network environment according to the total speed required value after air interface speed limiting under the sub-network environment and/or the total speed required value without air interface speed limiting under the sub-network environment;
the total rate requirement value under the whole network environment is as follows: 14.95Mb +64 Mb-78.95 Mb;
then, identifying and limiting the speed of the equipment load, and determining a flow threshold corresponding to the equipment load in the whole network environment;
because the CPU conditions corresponding to different devices are different, the load conditions of the different devices are different, the packet forwarding rate pps of the maximum capacity of the device with the main frequency of 800Mb can reach 80000pps, and the packet forwarding rate pps of the maximum capacity of the device with the main frequency of 450Mb can reach 40000 pps;

then bps [150bytes ]. pps [40000] ═ 60 Mb; the maximum flow rate limit of the equipment in the system;
determining a flow rate limit corresponding to a CPU occupied by a non-forwarding service on the equipment and a flow rate limit corresponding to a reserved vacant load;
in addition, the non-forwarding service on each device in the device has a flow limit corresponding to the CPU;
and the flow limit corresponding to the vacant load needing to be reserved;
and removing the flow rate limit corresponding to the CPU occupied by the non-forwarding service in the equipment and the flow rate limit corresponding to the reserved vacant load from the maximum flow rate limit to be used as a flow threshold corresponding to the equipment load.
In this embodiment, when other non-forwarding services on the device occupy CPU up to 20%, that is, the corresponding forwarding service can occupy CPU 70% at this time; in addition, 10% of the CPU is occupied as a vacant load; then the flow threshold corresponding to the equipment load is 60Mb by 70% ═ 42 Mb;
and when the total speed required value under the whole network environment is greater than the flow threshold corresponding to the equipment load, calculating an average dynamic speed limit value according to the flow threshold corresponding to the equipment load and the number of terminals, and determining to limit the speed of the access terminal according to the average dynamic speed limit value.
Then for the peak period of the network, the speed limit for a large number of students using the network is adjusted as follows:
