Detailed Description

In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

When a user is in a collaborative office, various services can be realized through the communication client, such as document sharing, document transmission to others, instant messaging and the like, can be realized at the communication client. Under such a complex multi-service collaboration scenario, the requirement of audio and video services cannot be met only by limiting the bandwidth reported by the log, and if a user needs to download a certain large-capacity file, the smoothness of an audio and video conference can be affected; if enough bandwidth is reserved only for the audio-video conference, the normal use of other services can be affected.

Based on this, the embodiment of the application provides a bandwidth control method, so as to ensure that a plurality of services can operate normally at the same time. In specific implementation, the bandwidth state of the network where the communication client is currently located and a plurality of running services in the communication client can be obtained, and the priority corresponding to each service is determined. And determining the bandwidth speed limiting strategy of any one of the plurality of services according to the bandwidth state of the current network and the priority of the service. And then sending the bandwidth speed limiting strategy of the service to a processing module corresponding to the service, so that the processing module controls the bandwidth allocated by the service based on the bandwidth speed limiting strategy. By the bandwidth control method provided by the application, reasonable bandwidths are allocated for the services with different priorities, so that each service can be guaranteed to normally operate under the current network.

In order to facilitate understanding of the technical solutions provided by the embodiments of the present application, the following description will be made with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a flowchart of a bandwidth control method according to an embodiment of the present application.

The method may be performed by a processing device of a communication client and may comprise the steps of:

s101: the bandwidth status of the current network and the running plurality of services are obtained.

When the user performs service cooperation through the communication client, the processing equipment of the communication client can acquire the bandwidth state of the current network of the communication client and a plurality of services which are operated simultaneously, so that the normal operation of the plurality of services is ensured by adjusting the bandwidths of different services.

In one possible implementation, the bandwidth status of the current network may be determined, and the packet loss rate and the delay of the current network may be obtained, where the packet loss rate refers to the ratio of the number of lost data packets to the transmitted data set during the data transmission process. The Time delay may be expressed as Round-Trip Time (RTT), which refers to the total Time required for receiving a receiver acknowledgement message after data is transmitted from a network transmitter to a receiver. And then determining the bandwidth value of the current network based on the congestion control algorithm, the obtained packet loss rate and the time delay. The higher the packet loss rate or the longer the delay, the smaller the bandwidth value of the current network will be. The congestion control algorithm is an open source algorithm, and will not be described herein. After obtaining the bandwidth value of the current network, the bandwidth range to which the bandwidth value belongs can be determined, so that the bandwidth class of the current network is determined according to the bandwidth range. Wherein, bandwidth range and bandwidth grade have a one-to-one correspondence. Alternatively, the correspondence between the bandwidth ranges and the bandwidth levels may be predetermined, that is, different bandwidth ranges correspond to different bandwidth levels. For example, it may be set that when the bandwidth range is greater than or equal to the first threshold, the bandwidth level is the first level, i.e. has a better network bandwidth; when the bandwidth range is greater than or equal to the second threshold value and smaller than the first threshold value, the bandwidth grade is the second grade, namely the current network bandwidth is in a general state; when the bandwidth range is smaller than the second threshold, the bandwidth level is a third level, i.e. the current network bandwidth is in a poor state, wherein the first threshold is larger than the second threshold. That is, the smaller the bandwidth value, the worse the corresponding bandwidth level.

It should be noted that, the embodiment of the present application is not limited to specific values of the first threshold and the second threshold, and may be set in combination with an actual application scenario. For example, the first threshold may be set to 800kps and the second threshold 400kps. The bandwidth values in the different ranges provided in the above embodiments are only exemplary illustrations, and are not limited to specific values for dividing the bandwidth ranges.

In one possible implementation, when the audio and video service of the communication client is running, the processing module of the audio and video service may obtain the packet loss rate and the delay of the current network, and then estimate the bandwidth value of the current network according to the packet loss rate and the delay by using the congestion control algorithm. In addition, the corresponding relation between the bandwidth range and the bandwidth grade can be stored in the processing module of the audio/video service in advance, so that the processing module of the audio/video service can determine the bandwidth grade of the current network according to the calculated bandwidth value, and then the running state of the current audio/video service and the obtained bandwidth grade are sent to the processor of the communication client.

Optionally, the processing module of the audio and video service may include an audio and video service processing module and an audio and video SDK, where the SDK refers to a software development kit, and generally includes a set of development tools when application software is built for a specific software package, a software framework, a hardware platform, an operating system, and the like. The audio/video SDK can acquire the packet loss rate and the time delay of the current network, then estimate the bandwidth value of the current network according to the packet loss rate and the time delay by using a congestion control algorithm, and determine the bandwidth grade corresponding to the bandwidth value according to the corresponding relation between the bandwidth range and the bandwidth grade. That is, the correspondence between the bandwidth range and the bandwidth level may be stored in the audio/video SDK in advance. The audio and video SDK can then send the bandwidth level to an audio and video service processing module, which can send the bandwidth level and the running state of the audio and video service to a processor of the communication client. In addition, the audio and video service processing module can also determine whether a user shares a document currently, and send the running state of the shared document to the processor.

In one possible implementation, when the audio and video service is not running, a network computing module of the communication client may collect a delay, a packet loss rate, and the like of the current network, calculate a bandwidth value of the current network, determine a bandwidth class, and send the bandwidth class to a processor of the communication client.

S102: and determining the priority corresponding to each service in the plurality of services.

In this implementation, the priorities corresponding to the services may be divided according to the importance of each service to the user. For example, the priority of audio-video traffic is greater than the priority of file transfer. And then the priority corresponding to each service is prestored in a configuration file of a processor of the communication client so that the processor can determine the priority corresponding to each service after acquiring a plurality of running services.

S103: for any one of a plurality of services, a bandwidth speed limit policy for the service is determined based on the bandwidth status and the priority of the service.

When there are multiple running services in the communication client, for any running service, the bandwidth speed limit policy of the service can be determined based on the bandwidth status of the current network and the priority of the service. For example, a bandwidth limit threshold may be determined for the traffic, the bandwidth limit threshold representing the maximum bandwidth that the traffic can allocate when running, i.e., the bandwidth allocated to the traffic cannot exceed the bandwidth limit threshold. The bandwidth state of the current network, the priority of the service and the bandwidth speed limit threshold of the service have a corresponding relationship, and the corresponding relationship can be pre-stored in a configuration file of a processor of the communication client. For example, the bandwidth limit threshold corresponding to the case where the bandwidth of the current network is the first level and the priority of the service is the first priority is different from the bandwidth limit threshold corresponding to the case where the bandwidth of the current network is the first level and the priority of the service is the second priority.

According to the above embodiment, it can be known that different bandwidth values correspond to different bandwidth levels, and in this embodiment of the present application, different bandwidth speed limit thresholds of the service may be set according to the different levels of the bandwidth. For example, when the bandwidth is in a better state, the service operation requirement can be met to a higher degree, so that the bandwidth speed limit threshold corresponding to the service is set to be higher, and the bandwidth operation speed of the service is higher; when the bandwidth is in a poor state, the service operation requirement cannot be met well, so that the bandwidth speed limit threshold can be set to be lower, namely the service is controlled to be in speed limit operation to a greater extent.

S104: and sending the bandwidth speed limiting strategy of the service to a processing module corresponding to the service, so that the processing module controls the bandwidth allocated by the service based on the bandwidth speed limiting strategy.

After determining the bandwidth speed limit policy for each service, the processor of the communication client may send the bandwidth speed limit policy of the service to the processing module corresponding to the service, so that the processing module controls bandwidth allocation of the service based on the bandwidth speed limit policy. The following description will be made in connection with different service scenarios.

In one possible implementation, when the running service includes an audio-video service, the processor of the communication client may determine a first priority corresponding to the audio-video service, and then determine a first bandwidth speed limit threshold corresponding to the audio-video service based on the bandwidth status of the current network and the first priority of the audio-video service. In addition, the processor of the communication client can also determine the image resolution and the frame rate of the audio and video service according to the bandwidth state of the current network, namely, when the bandwidth level is higher, the image resolution and the frame rate of the audio and video service can be properly improved, and the smoothness and the definition of the audio and video service are ensured; when the bandwidth level is lower, the image resolution and the frame rate of the audio and video service can be properly reduced, and the smoothness of the call is ensured by reducing the definition of the video. And then the processor of the communication client can send the first bandwidth speed limiting threshold, the image resolution and the frame rate corresponding to the audio and video service to the processing module of the audio and video service, and the processing module of the audio and video service regulates and controls the bandwidth of the audio and video service according to the first bandwidth speed limiting threshold and regulates the definition of the video according to the image resolution and the frame rate. According to the above embodiment, the processing module of the audio/video service may include an audio/video service processing module and an audio/video SDK, and then the communication client may send the first bandwidth speed limit threshold, the image resolution and the frame rate to the audio/video service processing module, and then the audio/video service processing module sends the first bandwidth speed limit threshold, the image resolution and the frame rate to the audio/video SDK again, and the audio/video SDK regulates and controls the bandwidth of the audio/video service according to the first bandwidth speed limit threshold and adjusts the definition of the video according to the image resolution and the frame rate.

In one possible implementation, when the running service includes file transfer, instant messaging, or log reporting, the corresponding service processing module is a network processing module. That is, the processor of the communication client may send the bandwidth speed limit threshold corresponding to the service to the network processing module, where the network processing module regulates and controls the bandwidth of the service according to the bandwidth speed limit threshold.

In one possible implementation, when the running service includes a shared document or a buried report, the corresponding service processing module is a web page view Webview processing module. That is, the processor of the communication client may send the bandwidth limit threshold corresponding to the service to the Webview processing module, where the Webview processing module regulates the bandwidth of the service according to the bandwidth limit threshold.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a communication client according to an embodiment of the present application. The communication client may include a processor 201, an audio video service processing module 202, an audio video SDK203, a network processing module 204, and a Webview processing module 205. The audio/video SDK203 may estimate a bandwidth value of the current network according to the packet loss rate and the time delay, determine a bandwidth class corresponding to the bandwidth value, and then send the bandwidth class to the audio/video service processing module 202, where the audio/video service processing module 202 may send the bandwidth class to the processor 201. The processor 201 may send the bandwidth limitation policy for the audio and video service to the audio and video service processing module 202, and then the audio and video service processing module 202 sends the bandwidth limitation policy for the audio and video service to the audio and video SDK203, where the audio and video SDK203 adjusts the audio and video service according to the bandwidth limitation policy for the audio and video service. The processor 201 may send a bandwidth limitation policy for a service such as file transmission, instant messaging, or log reporting to the network processing module 204, where the network processing module 204 adjusts the bandwidth of the service to limit the speed. The processor 201 may send a bandwidth limitation policy for services such as shared documents or embedded point reporting to the Webview processing module 205, and the Webview processing module 205 adjusts the bandwidth limit of the services.

In one possible application scenario, the priority order of different services may be set as follows: audio service > shared document > video service > instant messaging > file transfer > log reporting. In this application scenario, the services being run in the communication client include: audio service, video service, shared document, instant communication and log reporting, wherein the bandwidth level of the current network is the second level, and the processor of the communication client can find the speed limiting strategy of each service corresponding to the low bandwidth level from the configuration file: the low priority service such as log report is allocated with little bandwidth, namely the bandwidth speed limit threshold is lower; allocating medium bandwidth to instant messaging; allocating higher bandwidth to video calls and shared documents; bandwidth is not limited for audio calls. Therefore, the blocking of the audio-video conference can be reduced, the loading time of the first screen of the shared document is shortened, the simultaneous operation of a plurality of services is ensured, and the operation effect of the service with higher priority can be improved.

By the bandwidth control method provided by the embodiment of the application, reasonable bandwidths can be allocated for the services with different priorities according to the bandwidth state of the current network, so that each service can be guaranteed to normally operate under the current network.

and the sending unit 304 is configured to send the bandwidth speed limiting policy of the service to a processing module corresponding to the service, so that the processing module controls the bandwidth allocated to the service based on the bandwidth speed limiting policy.

In one possible implementation, the determining of the bandwidth status includes: acquiring the packet loss rate and the time delay of the current network; determining a bandwidth value of the current network based on a congestion control algorithm, the packet loss rate and the time delay; and determining the bandwidth grade of the current network based on the bandwidth range to which the bandwidth value belongs, wherein the bandwidth range has a corresponding relation with the bandwidth grade.

In a possible implementation manner, the second determining unit 303 is specifically configured to determine a bandwidth speed limit threshold corresponding to the service based on the bandwidth status and a priority corresponding to the service, where the bandwidth status, the priority, and the bandwidth speed limit threshold have a corresponding relationship.

In one possible implementation manner, when the service is one of file transmission, instant messaging and log reporting, the processing module corresponding to the service is a network processing module.

In one possible implementation manner, when the service is a shared document or a buried point report, the processing module corresponding to the service is a web page view Webview processing module.
