Problems solved by technology

[0006] In order to solve the problem of unreasonable upload bandwidth allocation and use in the existing cloud live broadcast platform, the present invention provides an upload bandwidth optimization method applied to the cloud live broadcast platform. Under limited circumstances, reduce the uploader's bandwidth overhead while ensuring a good viewing experience for users, and consider the number of viewing users of different uploaders, so as to provide the best possible user experience while reducing traffic charges

Embodiment 1

[0061] Such as figure 1 As shown, the method provided by the invention specifically includes the following steps:

[0062] S1. Define set u={u 1 , u 2,...,u N} represents the group of uploaders, Indicates the set formed by the upload bit rate selected by each uploader in the uploader group, Among them, b represents the maximum upload bandwidth of the cloud live broadcast platform; let r min and to represent the minimum upload bandwidth limit and maximum upload bandwidth limit for each uploader, namely:

[0063]

[0064] S2. Define the bandwidth cost C of the i-th uploader i for:

[0065] C i = c i *r i

[0066] where c i Indicates the traffic fee caused by unit bandwidth consumption;

[0067] S3. Define the QoE model of the viewing user of the i-th uploader as:

[0068]

[0069] Define the QoE model of the viewing user when the i-th uploader uploads with the minimum upload bandwidth:

[0070]

[0071] S4. Combining the bandwidth overhead of the i-th...

Abstract

The invention discloses an uploading bandwidth optimization method applied to a cloud live broadcast platform from a perspective of the cloud live broadcast platform. The bandwidth cost of an uploader is reduced while the good view experience of a user is guaranteed under the condition of the limited uploading bandwidth, the number of viewers of different uploaders is considered, and the best possible user experience can be provided while the traffic cost is reduced. The method is based on an optimal framework of an NBS (Nash Bargaining solution), the number of the different viewers of the different uploaders is considered under the condition of the limited uploading bandwidth, the uploading bandwidth is distributed to each participator fairly and effectively, and the global optimum is realized while the optimal individual interest is realized.

Description

technical field [0001] The invention relates to the field of multimedia network and cloud computing resource management, and more specifically, to an upload bandwidth optimization method applied to a cloud live broadcast platform. Background technique [0002] With the wide coverage of video terminal equipment and the rise of Internet high-bandwidth-consuming applications, cloud live broadcast platforms have emerged one after another and brought a huge increase in network traffic. In recent years, many cloud live broadcast platforms have emerged at home and abroad, and many successful practices have been carried out. The more popular cloud live broadcast platforms in China include Douyu live broadcast platform, Huya live broadcast platform and Dragon Ball live broadcast platform. The more popular cloud live streaming platforms abroad include Twitch.tv, YouTube, and Azubu.tv. The content of the cloud live broadcast platform covers a wide range, involving live game content l...
