Embodiment Construction

[0038] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be further clearly, completely and detailedly described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0039] The main platform for Internet video content distribution includes a large content delivery network (Content Delivery Network, CDN). Utilizing a CDN usually requires negotiation with a CDN service provider and relatively high deployment costs. The P2P (Peer to Peer) system requires minimal infrastructure, but it will cause video startup delays due to a large number...

Abstract

The invention discloses a cloud video service oriented resource provision method, comprising: obtaining system parameters from a cloud video service system; obtaining a minimum cost function and optimization constraints according to the system parameters; using an Lyapunov optimization framework to obtain a displacement-penalty function of the minimum cost function and an upper bound of the displacement-penalty function; and extracting parts relevant to resource provision from the upper bound of the displacement-penalty function, and calculating a resource provision solution. The cloud video service oriented resource provision method disclosed by the invention is used for considering a request allocation problem while solving the resource provision problem, which is beneficial to obtain an optimal decision. Scenes occurring in such practical applications as randomly arriving loads, different QoE requirements, simultaneous service of multiple CSPs and the like are considered at the same time, and a solution of the complicated scenes is provided, so that the cloud video service oriented resource provision method has a practical application value.

Description

technical field [0001] The present invention relates to the technical field of cloud video services, in particular, to a resource provision method for cloud video services. Background technique [0002] Internet video has high requirements on bandwidth and CPU performance. On the one hand, according to Cisco’s forecast in 2013, the contribution of global Internet video traffic to the entire Internet traffic in 2017 will increase from 57% in 2012 to 69%, and the annual growth rate of Internet video traffic will reach 34%. To meet different application requirements, it is usually necessary to do some computationally intensive processing on the video, such as compression, transcoding, encoding / decoding, self-adaptation, abstract extraction, rendering, etc. For example, an online video game scene needs to be rendered dynamically as the player moves; different players often require different video encodings depending on the device screen. However, in order to reduce the pressur...
