Specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, be not intended to limit the present invention.
As shown in figure 1, a kind of Multi-channel load equilibrium audio/video transmission method principle flow chart providing for the embodiment of the present invention 1, wherein,
Step 11, audio-video document is split as several packets；
Step 12, described allocation of packets is transmitted to different channels；
Step 13, counts the data packet number that each channel is an actually-received；
Step 14, adjusts the quantity sending described packet on each channel according to described data packet number.
Wherein, the quantity that each channel sends described packet is adjusted according to described data packet number, specifically include：
Send for the high more packet of described channel distribution of described success rate；Or
Send for the less packet of described low success rate of described channel distribution.
Described allocation of packets is transmitted to different channels, including：
Described packet is evenly distributed to different channels be transmitted.
Statistics sets the data packet number receiving on each channel in duration, and the data packet number being sent with transmitting terminal is compared, and obtains described success rate.
Specifically, Multi-channel load equilibrium is the core technology of the present embodiment.Load balancing is exactly to pass through specific optimized algorithm, real-time bandwidth according to each channel module, when some channel signals are bad or disconnect, the load balance of network transmission to the preferable channel of signal on, thus avoiding because signal is weaker and base station switches the unstable networks leading to.
Audio video transmission of the prior art typically uses a mixed-media network modules mixed-media and is transmitted, as shown in Figure 2, it is exactly the network interface card generally said, audio, video data frame transmits data to server by this mixed-media network modules mixed-media, there is no immunity for network fluctuation, it is that we cannot tackle the transmission problem that network fluctuation leads to when this mixed-media network modules mixed-media goes wrong.
The present embodiment carries out network service using multichannel, controlled by the algorithm of a set of load balancing, audio/video frames are splitted into multiple packets, it is transmitted by different mixed-media network modules mixed-medias (channel), the amount of capacity of each mixed-media network modules mixed-media channel can be obtained by calculating the success rate given out a contract for a project simultaneously, the larger channel of capacity will send more packet, and the less channel of capacity will distribute less data bag.When a mixed-media network modules mixed-media quits work or capacity is extremely low, algorithm ignores that this module, proceeds to communicate using other modules.
Specifically, in the present embodiment, statistics can not be success rate, but the data volume that server is an actually-received.For example, threshold can be the value of a general 2M, and server, after receiving the data of 2M, can count in this 2M, how many is to receive from channel 1, i.e. data (1), how many is to receive from channel 2, i.e. data (2), count on channel m successively, i.e. data (m), then returns to transmission program this value, and program is assigned to max this value again.
Specifically as shown in figure 3, wherein, audio, video data bag passes through multiple channels and sends packets, is then passed through network and is sent to server.Through the load-balancing algorithm of the present embodiment, constantly adjust the quantity that each channel sends packet, thus realizing each channel all obtain packet transmission work to greatest extent.
In specific load-balancing algorithm, record the sequence number (i) of each mixed-media network modules mixed-media, and a max is set for itiValue, that is, maximum can send data.When program starts, algorithm average successively can send quantitative data by each mixed-media network modules mixed-media, after the data that receiving terminal receives reaches threshold value threshold set in advance (be defaulted as 1MB, or set as needed), it is recv according to each data volume receivingijCalculate data volume data that each mixed-media network modules mixed-media is actually reachedi：
Wherein, i is mixed-media network modules mixed-media sequence number, and j is which time receives, and n is total reception number of times, and m is mixed-media network modules mixed-media sum.
Then receiving terminal returns datai, program updates max according to this value：
maxi=datai
Program sends, in next time, the max that can update when data according to thisiTo determine the data volume that map network module sends.The data volume treating the transmission of all-network module is more than maxiAfterwards, continue according to this maxiSend.Until next max value is updated, repeat above step.
It is specifically shown in Fig. 4, wherein, packet passes through different channels and sends, and each channel is transmitted by the data volume of max.After receiving terminal (server) receives the packet of threshold quantity, carry out the calculating of success rate, then feed back to transmitting terminal and adjust the quantity that packet is sent on each channel.
Just because of such a mechanism, it is not in the frame losing phenomenon such as interim card, Hua Ping that multi channel networks just can make the audio frequency and video of transmission.In the case of network environment is reasonable, this mechanism can significantly improve the network bandwidth, when being in the poor environment of network, or when constantly switching base station during quick motion, multi channel advantage is embodied in by load balancing, can stabilize the video interim card problem that network fluctuation brings to the full extent.
The embodiment of the present invention, due to employing technique scheme, compared with prior art, carry out network transmission by using multiple network transmission channel, and be the suitable volume of transmitted data of multiple channel distributions by load-balancing algorithm, when the bad switching with base station of some channel signals, channel by load turn signal preference, meanwhile, multichannel also can significantly improve the network bandwidth so that the stability of network transmission is greatly improved.
