Fig. 1 is a flow chart of a bandwidth allocation method provided by an embodiment of the present disclosure, where the embodiment of the present disclosure is applicable to a situation where bandwidth allocation is performed for a plurality of different types of media streams in one communication link, and especially a weak network scenario where network status fluctuates during real-time communication. The method may be performed by a bandwidth allocation device, which may be implemented in the form of software and/or hardware, alternatively by an electronic device, which may be a mobile terminal, a PC-side or a server, etc.

As shown in fig. 1, the bandwidth allocation method includes:

s110, obtaining coding attribute information, bandwidth allocation priority and allocatable bandwidth of a plurality of kinds of media streams in a target communication link.

The communication link may be any connection path established between two parties with data interaction, and data transmission and information exchange may be performed based on the connection path. The target communication link may be any communication link that needs bandwidth allocation during data transmission. Such as a data communication link during live broadcast or a data communication link during video call.

The media stream may be a data stream streamed in the target communication link. Depending on the type of data or the purpose of the data, multiple types of media streams, such as audio streams, video streams, and shared streams, may be included in the target communication link at the same time.

In the process of transmitting each media stream, bandwidth is allocated in advance according to the coding requirement of each type of media stream. In the case of a better network state, each media stream can obtain enough bandwidth for 'higher quality' data transmission. The "higher quality" may be determined by evaluation from the perspective of the receiving side of the media stream data, such as the sharpness of the video or the degree of audio jamming. When there is a fluctuation in the network state and the estimated bandwidth result cannot meet the above-mentioned "higher quality" data transmission, bandwidth allocation needs to be performed more carefully to meet the quality of user experience in the case of weak networks as much as possible.

Then, the coding attribute information, the bandwidth allocation priority, and the allocatable bandwidth are all parameters required in determining the bandwidth allocation result. The coding attribute information may be a coding code rate value corresponding to each type of media stream. Different code rate values correspond to different data qualities, and the size of the code rate value is proportional to the data quality (e.g., video frame sharpness). The coding attribute information may include a plurality of preset coding code rate values matched with each type of media stream, such as a preset minimum coding code rate value, a preset maximum coding code rate value, and coding code rate values corresponding to different degrees of data quality. For example, the reference coding rate value corresponding to each type of media stream in the lowest preset bandwidth allocation gear may be a preset minimum coding rate for each type of media stream; the reference coding rate value corresponding to each type of media stream in the highest preset bandwidth allocation gear can be the preset maximum coding rate of each type of media stream.

It is understood that the code rate values corresponding to the different degrees of data quality may be any value between a preset minimum code rate value and a preset maximum code rate value. The bandwidth allocation priority may be used to determine the order in which bandwidth is allocated for each type of media stream, with a higher priority for a first allocation and a lower priority for a second allocation. The allocatable bandwidth may be a bandwidth value determined from the bandwidth estimation result, which is the total bandwidth that the target communication link may allocate for use. The allocatable bandwidth may be part or all of the bandwidth estimation result, and may be determined according to the bandwidth usage in the actual traffic scenario.

And S120, based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority, according to a preset bandwidth allocation gear, sequentially performing bandwidth allocation on the media streams of each class from low to high in sequence until no bandwidth can be allocated or the highest bandwidth allocation gear is reached.

The preset bandwidth allocation gear is a bandwidth allocation policy set for more efficient bandwidth allocation in the present embodiment. Different preset bandwidth allocation gears correspond to different bandwidth values, and the higher the bandwidth allocation gears are, the larger the corresponding bandwidth values which can be allocated to each type of media stream are.

In particular, the allocation may be performed starting from the lowest preset bandwidth allocation gear (noted as first gear). If the bandwidth allocation policy of the first gear is according to the bandwidth allocation order corresponding to the bandwidth allocation priority, allocating bandwidth for each type of media stream successively. If the allocable bandwidth is already allocated in the first gear bandwidth allocation process, the bandwidth allocation work is completed. If, in the bandwidth allocation process of the first gear, after each type of media stream is allocated to obtain the bandwidth corresponding to the current bandwidth allocation gear, the bandwidth is further allocated according to the bandwidth allocation policy of the second gear adjacent to the lowest preset bandwidth allocation gear until no bandwidth is allocated or the highest bandwidth allocation gear is reached. In the highest bandwidth allocation gear, each type of media stream data is encoded and transmitted with the highest encoding rate, so that the experience quality of the media stream data is ensured.

Further, the bandwidth allocation policy in each preset bandwidth allocation gear may be that a bandwidth allocation result of each type of the media stream is determined according to the real-time network state and the coding attribute information of the target communication link; the coding attribute information comprises a reference coding code rate value matched with each preset bandwidth allocation gear. The real-time network state can be represented by data such as packet loss rate, data round-trip transmission delay, data retransmission rate, and forward error correction related parameters. The redundancy rate in the process of bandwidth allocation can be determined through the real-time network state, so that the final bandwidth allocation result is determined according to the coding rate value of each type of media stream in the corresponding bandwidth allocation gear.

The step-by-step and layer-by-layer progressive bandwidth allocation is performed on each type of media stream, so that the media streams with different priorities can be allocated to obtain a certain bandwidth for data transmission from the lowest standard, and the data transmission of each type of media stream is ensured. Under the condition that the allocable bandwidth is enough, each media stream can be allocated with more bandwidth according to the bandwidth allocation priority, so that the data quality of the media stream is improved.

According to the technical scheme, coding attribute information, bandwidth allocation priority and allocatable bandwidth of a plurality of types of media streams in a target communication link are acquired; based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority, allocating bandwidth for each type of media stream in sequence according to the preset bandwidth allocation gear configuration until no bandwidth can be allocated or the highest bandwidth allocation gear is reached; in each preset bandwidth allocation gear, determining a bandwidth allocation result of each type of media stream according to the real-time network state and the coding attribute information of the target communication link; the coding attribute information includes a reference coding rate value that matches each preset bandwidth allocation gear. The technical scheme of the embodiment of the disclosure solves the problem that the existing bandwidth allocation strategy can not simultaneously consider the bandwidth requirements of the high-priority media stream and the low-priority media stream, and can reallocate the bandwidth on the basis of guaranteeing the basic operation of each priority media stream through the stepped multiple bandwidth allocation strategy so as to simultaneously meet the bandwidth requirements of the media streams with different priorities.

Fig. 2 is a flow chart of a bandwidth allocation method according to an embodiment of the present disclosure, which further illustrates a process of reallocating the remaining bandwidth based on the above embodiment, so as to achieve more sufficient bandwidth utilization. The method may be performed by a bandwidth allocation device, which may be implemented in the form of software and/or hardware, optionally by an electronic device, which may be a mobile terminal, a PC-side or a server, etc.

As shown in fig. 2, the bandwidth allocation method includes:

s210, obtaining coding attribute information, bandwidth allocation priority and allocatable bandwidth of a plurality of kinds of media streams in a target communication link.

And S220, based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority, according to a preset bandwidth allocation gear, sequentially performing bandwidth allocation on the media streams of each class from low to high in sequence until no bandwidth can be allocated or the highest bandwidth allocation gear is reached.

Further, the bandwidth allocation policy in each preset bandwidth allocation gear may be that a bandwidth allocation result of each type of the media stream is determined according to the real-time network state and the coding attribute information of the target communication link; the coding attribute information comprises a reference coding code rate value matched with each preset bandwidth allocation gear. The real-time network state can be represented by data such as packet loss rate, data round-trip transmission delay, data retransmission rate, and forward error correction related parameters. The redundancy rate in the process of bandwidth allocation can be determined through the real-time network state, so that the final bandwidth allocation result is determined according to the coding rate value of each type of media stream in the corresponding bandwidth allocation gear. The calculation process of the multiplying power in real time can be expressed as the following calculation process: real-time redundancy ratio= (retransmission budget code rate/historical statistical code rate value in last bandwidth allocation period) +forward error correction ratio calculated based on preset forward error correction policy. The historical statistic coding code rate value refers to the code rate of the pure media stream packets except the retransmission data packet and the forward error correction data packet counted in the preset historical time.

In an alternative embodiment, in the preset bandwidth allocation gear, the bandwidth redundancy factor corresponding to the lowest preset bandwidth allocation gear may be set to zero. And in the preset bandwidth allocation gear, the bandwidth redundancy rate corresponding to the highest preset bandwidth allocation gear is set as the preset maximum redundancy rate. The preset maximum redundancy rate is usually fixed to be 4 times, so that 70% packet loss scenes can be resisted.

S230, determining whether residual bandwidth exists in each type of media stream.

In this step, after the bandwidth allocation step is completed, the actual bandwidth utilization of each type of media stream is analyzed. Some media stream data, although allocated sufficient bandwidth, may not be fully utilized by its allocated bandwidth during data transmission. For example, when video picture content corresponding to video stream data encoded content is still pictures, consumed bandwidth is very low. Illustratively, if a video stream is divided into 1000kbps bandwidth, but it actually occupies only 100kbps bandwidth, then 900kbps bandwidth is wasted.

The residual bandwidth of each type of media stream is the unused bandwidth determined by subtracting the utilized bandwidth value from the assigned bandwidth value after each type of media stream is assigned with a certain bandwidth.

And S240, under the condition that any type of media stream has residual bandwidth, distributing the residual bandwidth according to the bandwidth distribution priority of each type of media stream without residual bandwidth until no residual bandwidth exists.

In case there is remaining bandwidth for any type of media stream, this indicates that there is also bandwidth available for allocation. To further increase bandwidth utilization, the remaining bandwidth is allocated to other media streams that do not have remaining bandwidth.

Specifically, the residual bandwidth allocation order of each type of the media stream without residual bandwidth can be determined according to the bandwidth allocation priority; and based on the residual bandwidth allocation sequence, allocating the residual bandwidth to each type of media stream without residual bandwidth according to a preset minimum coding rate of each type of media stream until no bandwidth can be allocated.

Wherein the order of bandwidth allocation may be the reverse order of bandwidth allocation priority, e.g., bandwidth allocation is prioritized for media streams with relatively low bandwidth allocation priority in each type of media stream where no bandwidth remains. This is because, in general, media streams with lower bandwidth allocation priorities are less likely to be allocated to bandwidth for sufficiently high quality data transmission, which may further guarantee the basic operation of low priority media streams.

According to the technical scheme, coding attribute information, bandwidth allocation priority and allocable bandwidth of each type of media stream in a target communication link are obtained; based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority, sequentially allocating bandwidth for each type of media stream from low to high according to a preset bandwidth allocation gear until no bandwidth can be allocated or the highest bandwidth allocation gear is reached; further, determining whether the residual bandwidth exists in each type of media stream, and if the residual bandwidth exists in any type of media stream, allocating the residual bandwidth according to the bandwidth allocation priority of each type of media stream without the residual bandwidth until no residual bandwidth exists. The technical scheme of the embodiment of the disclosure solves the problem that the existing bandwidth allocation strategy can not simultaneously consider the bandwidth requirements of high-priority media streams and low-priority media streams, and can reallocate the bandwidth on the basis of guaranteeing the basic operation of each priority media stream through a stepwise multiple bandwidth allocation strategy so as to simultaneously meet the bandwidth requirements of the media streams with different priorities, and further reallocate the allocated and unused residual bandwidth, thereby fully improving the bandwidth utilization rate.

Fig. 3 is a schematic flow chart of a bandwidth allocation method according to an embodiment of the present disclosure, and on the basis of the foregoing embodiment, in a process of implementing the flow chart of the bandwidth allocation method, a situation of performing bandwidth allocation gear setting is further explained. The method may be performed by a bandwidth allocation device, which may be implemented in the form of software and/or hardware, optionally by an electronic device, which may be a mobile terminal, a PC-side or a server, etc.

As shown in fig. 3, the bandwidth allocation method includes:

s310, obtaining coding attribute information, bandwidth allocation priority and allocatable bandwidth of a plurality of kinds of media streams in a target communication link.

In this embodiment, four bandwidth allocation gears are preset, bandwidth allocation is primarily performed, and specific setting conditions of each preset bandwidth allocation gear may refer to the schematic diagram shown in fig. 4.

S320, bandwidth allocation is sequentially carried out on the media streams of each type according to a first preset bandwidth allocation gear based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority.

The first preset bandwidth allocation gear is the lowest gear for bandwidth allocation for the first time.

And in the first preset bandwidth allocation gear, according to the bandwidth allocation priority, allocating according to the minimum coding rate of each media stream. If the first preset bandwidth allocation gear is allocated once, the lowest working interval of the audio and video streams can be met under the condition of not considering the network. If the network is normal, the audio and video call is normal, but the condition of video blurring and sound roughness can occur. If the network has packet loss, the media stream data is not basically analyzed and displayed. I.e. the quality of the data of each media stream is relatively low when the allocation is performed only according to the first preset bandwidth allocation gear.

And in the process of carrying out bandwidth allocation according to the first preset bandwidth allocation gear, if the allocable bandwidths are allocated completely, ending the bandwidth allocation process.

S330, under the condition that the allocatable bandwidth exists, bandwidth allocation is sequentially carried out on the media streams of each type according to a second preset bandwidth allocation gear based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority.

In the second preset bandwidth allocation gear, according to the bandwidth allocation priority, the bandwidth of each media stream can be allocated to a minimum code rate, wherein the minimum code rate is the product of the minimum coding code rate in the step and the current real-time redundancy rate. If the bandwidth of each media stream is only allocated to the second preset bandwidth allocation gear, the data stream can be transmitted when the packet loss condition exists in the network, if the data stream can normally communicate in the audio/video communication scene, but the video is blurred and the sound is rough.

And in the process of carrying out bandwidth allocation according to the second preset bandwidth allocation gear, if the allocable bandwidths are allocated completely, ending the bandwidth allocation process.

And S340, under the condition that the allocatable bandwidth exists, based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority, sequentially performing bandwidth allocation for each type of media stream according to a third preset bandwidth allocation gear.

And in a third preset bandwidth allocation gear, according to the bandwidth allocation priority, the bandwidth of each media stream can be allocated to an optimal code rate, wherein the optimal code rate is the product of a preset maximum coding code rate and the current real-time redundancy rate. If each media stream bandwidth is only allocated to the third preset bandwidth allocation gear, the data stream transmission quality is relatively high when the network has packet loss. If the voice call is in the audio-video call scene, the voice call can be normally performed, but the video picture is high-definition and the voice is clear.

And in the process of carrying out bandwidth allocation according to the third preset bandwidth allocation gear, if the allocable bandwidths are allocated completely, ending the bandwidth allocation process.

And S350, under the condition that the allocatable bandwidth exists, bandwidth allocation is sequentially carried out on the media streams of each type according to a fourth preset bandwidth allocation gear based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority.

In the fourth preset bandwidth allocation gear, according to the bandwidth allocation priority, the bandwidth of each media stream can be allocated to a maximum code rate, wherein the maximum code rate is the product of a preset maximum coding code rate and a preset maximum redundancy rate. If the bandwidth of each media stream is allocated to the fourth preset bandwidth allocation gear, when the packet loss rate is large under the condition of extreme fluctuation of the network, normal conversation can be performed under the scene of audio-video conversation, the video picture is high-definition, and the sound is clear. The allocatable bandwidth can be allocated after passing through four preset bandwidth allocation gears, and if not, the bandwidth allocation process is stopped.

S360, determining whether the residual bandwidth exists in each type of media stream, and if the residual bandwidth exists in any type of media stream, distributing the residual bandwidth according to the bandwidth distribution priority of each type of media stream without the residual bandwidth until no residual bandwidth exists.

According to the technical scheme, through presetting four bandwidth allocation gears, when bandwidth allocation is needed, coding attribute information, bandwidth allocation priority and allocatable bandwidth of a plurality of types of media streams in a target communication link are obtained; based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority, sequentially performing bandwidth allocation for each type of media stream according to a first preset bandwidth allocation gear; under the condition that the allocatable bandwidth exists, based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority, sequentially performing bandwidth allocation on each type of media stream according to a second preset bandwidth allocation gear; under the condition that the allocatable bandwidth exists, based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority, sequentially performing bandwidth allocation on each type of media stream according to a third preset bandwidth allocation gear; under the condition that the allocatable bandwidth exists, based on the bandwidth allocation sequence corresponding to the bandwidth allocation priority, sequentially performing bandwidth allocation on each type of media stream according to a fourth preset bandwidth allocation gear; and determining whether the residual bandwidth exists in each type of media stream, and if the residual bandwidth exists in any type of media stream, distributing the residual bandwidth according to the bandwidth distribution priority of each type of media stream without the residual bandwidth until no residual bandwidth exists. The technical scheme of the embodiment of the disclosure solves the problem that the existing bandwidth allocation strategy can not simultaneously consider the bandwidth requirements of high-priority media streams and low-priority media streams, and can reallocate the bandwidth on the basis of guaranteeing the basic operation of each priority media stream through a stepwise multiple bandwidth allocation strategy so as to simultaneously meet the bandwidth requirements of the media streams with different priorities, and further reallocate the allocated and unused residual bandwidth, thereby fully improving the bandwidth utilization rate.
