Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The parameters involved in the method for allocating energy-efficient resources in a multimedia cloud data center based on user experience in the present invention are as follows:

[0025] (1) User Experience (UX or UE for short) is a purely subjective psychological feeling established in the process of using cloud services by cloud users, and it is the user's subjective experience of cloud services obtained.

[0026] (2) User experience degree. User experience degree (UED) is a quantitative value of user experience, which reflects the ability of the provided service to meet user needs. It is a real number greater than or equal to 0. more satisfied.

[0027] (3) Overall user experience of the system, which is the degree of satisfaction of all users to the service capability of the entire system, expressed by the sum of user ex...

Abstract

The invention relates to a multimedia cloud data center energy efficient resource allocation method based on user experiences. The method includes that a user initiates an application request to the multimedia cloud data center, the data center queues up the request of the user when the time slot t starts, the actual queue is initialized, and the virtual queue is calculated; the user responds the time according to his own device and the corresponding application expectation defined by network conditions; the data center calculates the maximum function of the actual queue and the user experiences by observing the user request queue and the requested arrival rate; the data center adjusts corresponding parameters according to the measurement of the user experiences to minimize the energy consumption function of the queues and the system so that the resource supplying quantity needed by the system can be confirmed; and the actual queue and the virtual queue are updated so as to enter the next time slot. The multimedia cloud data center energy efficient resource allocation method introduces the user experiences into the cloud calculation resource allocation strategy, minimizes the use of the cloud resource on the premise that the user experiences are satisfied, and reduces the system energy consumption of the multimedia cloud data center.

Description

technical field [0001] The invention relates to a method for allocating multimedia cloud resources, in particular to a method for allocating resources with high energy efficiency in a multimedia cloud data center based on user experience. Background technique [0002] With the development of Web 2.0 and Web 3.0, multimedia information on the Internet is increasingly provided to public users in the form of services, and multimedia computing has become an attractive technology. The computing-intensive feature of multimedia services requires a large amount of computing resources. At the same time, many multimedia services, such as streaming media distribution, have high requirements for real-time performance, and require back-end computing resources capable of powerful and efficient large-scale computing. [0003] Cloud computing is a computing model that provides virtual services through the network. This model is dynamic and scalable, and can efficiently meet the intensive r...
