Problems solved by technology

Multiple users connected at this time cannot automatically adjust the rate to match the rate of the uplink port
When the total bandwidth of the uplink port changes due to external factors, the user bandwidth cannot be automatically adjusted accordingly
When the rate of the uplink port decreases, the user bandwidth cannot be kept stable; when the rate of the uplink port increases, the user cannot share the advantage of increased bandwidth
In addition, when some users have less traffic, the excess bandwidth cannot be shared with other users

Embodiment 1

[0024] A method for configuring multi-user bandwidth equalization, which is suitable for networks including flow control functions. The method achieves the purpose of detecting the total uplink bandwidth by increasing the bandwidth margin on the basis of the actual rate. At the same time, allocate the set total rate, detect users whose actual bandwidth is lower than the allocated bandwidth, and maximize the bandwidth used by other users on the basis of ensuring the flow of low-bandwidth users. Such as figure 1 As shown, the multi-user bandwidth equalization configuration method specifically includes the following steps:

[0025] 1) Set the total bandwidth V of the uplink port S The initial value of is set according to the empirical value.

[0026] 2) According to V S Set the configuration bandwidth V of N users avg , V avg =V S / N.

[0027] 3) Collect the actual rate V of each user according to a certain detection period T Ti , 1≤i≤N, and calculate the actual total ba...

Embodiment 2

[0035] refer to figure 1 As shown, in the method for configuring multi-user bandwidth equalization in this embodiment, a=0.85, b=0.91, c=10%, x=10%, and the rest are the same as in Embodiment 1.

Abstract

The invention relates to a method for multi-user bandwidth balanced configuration. The method comprises the following steps: 1, setting an initial value of an uplink port total bandwidth VS; 2, setting the configuration bandwidths Vavg of N users according to Vs; 3, acquiring the actual velocity VTi of each user according to a certain detection period, and calculating the actual total bandwidth VT of all the current users; 4, judging whether the value of the uplink port total bandwidth VS needs to the adjusted or not according to the value of the current actual total bandwidth VT, and if yes, adjusting the value of VS; 5, judging whether the actual velocities of all the users are larger than or equal to the current configuration bandwidth Vavg or not, if yes, returning to the step 2, and if not, executing a step 6; and 6, adjusting the configuration bandwidths of the users with the current actual velocities being smaller than the configuration bandwidths to VTi (1+x), and distributing the residual bandwidths to the residual users. Compared with the prior art, the method has the advantages of stabilizing the user bandwidths, increasing the bandwidth utilization rate and the like.

Description

technical field [0001] The invention relates to a wireless network control method, in particular to a multi-user bandwidth equalization configuration method. Background technique [0002] In a wireless network device, the total bandwidth of an uplink port of a switch will vary with various factors. The current main method of guaranteeing user bandwidth is to configure guaranteed bandwidth for each user. Multiple users connected at this time cannot automatically adjust the rate to match the rate of the uplink port. When the total bandwidth of the uplink port changes due to external factors, the user bandwidth cannot be automatically adjusted accordingly. When the rate of the uplink port drops, the user bandwidth cannot be kept stable, and when the rate of the uplink port increases, the user cannot share the advantage of increased bandwidth. In addition, when some users have less traffic, the excess bandwidth cannot be shared with other users. Contents of the invention ...
