Specific embodiment
Hereinafter, the present invention will be described in detail with reference to various embodiments shown in the accompanying drawings.But these embodiments are not
The limitation present invention, structure that those skilled in the art are made according to these embodiments, method or change functionally
It changes and is included within the scope of protection of the present invention.
The present invention relates to provide it is a kind of for bandwidth is evenly distributed in wireless network environment to guarantee the big video of data volume
The equipment and system of the fluency of the distribution of stream, it includes following part:
Step 1: allocation strategy is formulated to the bandwidth of wireless network.
There are two ways to distribution, the first is to carry out bandwidth allocation according to the connection quantity of setting；Be for second according to
The code rate size of video flowing is allocated.
It is fixedly connected in the allocation flow of quantity for a further understanding of first method referring to Fig. 2, it is first determined
In application environment, maximum terminal quantity N that equipment can connect.Then corresponding to the standard for the WiFi interface being equipped with according to equipment
Maximum data transmission rate, calculate each terminal and connect the maximum effective bandwidth numerical value that can be obtained.Below by way of enumerating one
A concrete instance further understands the method for carrying out bandwidth allocation according to terminal connection quantity.
The WiFi interface standard that one equipment is equipped with is 802.11n.According to the standard of 802.11n, wireless maximum transmission
Rate can achieve 300M bit per second, 300Mbps (bits per second).If application scenarios require wireless network view
The connection terminal quantity supported required for frequency discharge device is 50, meanwhile, set wireless network effective bandwidth coefficient as 0.5,
So each terminal connects the maximum bandwidth that can be obtained or transmission rate is
300x 0.5/50=3Mbps
I.e. each intelligent terminal can obtain the maximum bandwidth for being no more than 3M.
For a further understanding of second method, referring to Fig. 3, the preferential uniform distribution flow figure of video code rate.First really
It is scheduled on the code rate for the video flowing installed in application environment.Code rate is higher, and the image quality of video is better.In the code for determining video flowing
After rate, the code rate numerical value for the video flowing installed in recording equipment, video code rate type.Distribution video flowing is calculated according to formula once
Required bandwidth, i.e.,
Maximum bandwidth=corresponding coefficient of efficiency of video stream bit rate x video stream bit rate type required for video flowing transmits.
It is being removed according to peak transfer rate corresponding to the WiFi interface standard of equipment multiplied by an effective bandwidth coefficient
With the video flowing transmission institute maximum bandwidth in need calculated in above-mentioned formula, it can be obtained what wireless device can connect
Maximum terminal quantity.
For this step that further sharpens understanding, connect below by way of enumerating a concrete instance and further understanding according to terminal
Connect the method that quantity carries out bandwidth allocation.
The WiFi interface standard that one equipment is equipped with is 802.11n.According to the standard of 802.11n, wireless maximum transmission
Rate can achieve 300M bit per second, 300Mbps (bits per second).If the video flowing that application scenarios require
Code rate is 1M bit per second, i.e. 1Mbps (bits per second), the code rate type of video flowing is VBR, i.e. dynamic code rate class
Type, its genre modulus are set as 2, then
Maximum bandwidth=1Mbps x 2=2Mbps required for video flowing transmits
The maximum terminal quantity that this equipment can connect
300x 0.5/2=75 platform
In in further explanation, used various coefficients can be adjusted according to actual application environment.
Step 2: after completing bandwidth allocation, the code rate to the video flowing of installation is needed to detect.If selection installation
The code rate of video flowing be higher than the setting value in application scenarios, then needing to carry out video flowing the primary adjustment for reducing code rate.
In order to further deepen the understanding of this step, further illustrated below by way of citing.
Or using example in step 1 continuing with.Being fixedly connected in the example of terminal quantity in step 1,
It is computed out in the case where the 300M rate of 802.11n, supports 50 terminals, the maximum bandwidth value that each terminal can obtain
For 3Mbps.
If it is determined that using VBR, the video flowing of dynamic code rate type, then the code rate of video flowing is 1.5Mbps, because dynamic
The effective bandwidth coefficient of the code rate of state type is 2, i.e. 1.5Mbps=3Mbps/2.The video stream bit rate of selection is greater than
The video flowing of the VBR type of 1.5Mbps needs its code rate being converted to 1.5Mbps or following in a pre-installation.
If it is determined that using ABR, the video flowing of average bit rate type, then the code rate of video flowing is 2Mbps, because average
The effective bandwidth coefficient of the code rate of type is 1.5, i.e. 2Mbps=3Mbps/1.5.2Mbps is greater than to the video stream bit rate of selection
The video flowing of ABR type need its code rate being converted to 2Mbps or following in a pre-installation.
If it is determined that using CBR, the video flowing of constant code rate type, then the code rate of video flowing is 3Mbps, because constant
The effective bandwidth coefficient of the code rate of type is 1, i.e. 3Mbps=3Mbps/1.It is greater than the CBR of 3Mbps to the video stream bit rate of selection
The video flowing of type needs its code rate being converted to 3Mbps or following in a pre-installation.
In in further explanation, used various coefficients can be adjusted according to actual application environment.
Step 3: after completing bandwidth allocation and preparation process, equipment operating data service establishes nothing on WiFi interface
Line local area network.In the connection request for receiving intelligent terminal, by DHCP function, with distributing the IP of network to intelligent terminal
Location guarantees the video multimedia data in the accessible equipment of intelligent terminal.
Step 4: after establishing network connection with intelligent terminal, the request for accessing the video multimedia data of selection is received
When, data services send video flowing according to the code rate formulated in the code rate strategy of setting to intelligent terminal.It is every in order to guarantee
The connection bandwidth usage amount of a terminal does not exceed the numerical value of setting, bandwidth allocation element can to the transmission rate of each connection into
Row monitoring in real time.There are two ways to monitoring, the first is preferential with Bandwidth guaranteed, is accounted for each connection transmission
Time is that benchmark control bandwidth uses.Two methods are further explained below.
First method is the directly simple method of comparison, i.e., within the period of setting, to the number of each connection transmission
According to progress mean value calculation.It is higher than the connection of the maximum limitation bandwidth of setting for average value, is reduced within next period
Volume of transmitted data, i.e. reduction transmission rate.With this repeatedly within the subsequent period, the progress of each connection is similarly grasped
Make, to guarantee evenly distributing for bandwidth.The performance difference that this method is suitable for each intelligent terminal is little, and wireless environment does not have
It is used in the case where too many interference.
Second method is monitored on the basis of transmission time.The transmission speed for the WiFi standard being had according to equipment
The maximum bandwidth value of the calculated each connection for needing to set, the maximum bandwidth value of setting is converted into passing in rate and step 2
The defeated time implements width monitoring.The characteristics of this method is mean allocation transmission time, does not calculate the transmission number in the unit time
According to amount, i.e. rate.It can guarantee the bandwidth reasonable distribution between the biggish intelligent terminal of performance difference in this way.In order to further add
The deep understanding to second method, further illustrates below by way of citing.
Or using example in step 1 continuing with.Being fixedly connected in the example of terminal quantity in step 1,
It is computed out in the case where the 300M rate of 802.11n, in order to support 50 terminals, the maximum belt that each terminal can obtain
Width values are 3Mbps.
Each occupied transmission time=1 second/50 of connection, i.e. 20ms so in the unit time.Control each connection
Using the time of transmission within 20ms.
The characteristics of second method be due to mean allocation data transmission period, avoid the bad intelligent terminal of performance because
The data receiver of the good terminal of performance is influenced compared with slow for speed；Equally, the intelligent terminal that also performance can be prevented good is because of performance
More bandwidth are occupied well.
In conclusion method of the invention can be summarized as including step 1: formulating distribution plan to the bandwidth of wireless network
Slightly, the maximum limitation bandwidth that the maximum intelligent terminal quantity that can connect and each intelligent terminal can obtain is determined；Step
Two: detecting and selecting the video stream bit rate type of installation, and the maximum limitation bandwidth setting that can be obtained according to each intelligent terminal
The setting code rate value of the application scenarios；Step 3: establishing Wireless LAN, so that the accessible video multimedia of intelligent terminal
Data；Step 4: according to the access request of intelligent terminal, video flowing is sent to intelligent terminal.
