Embodiment Construction

[0026] In order to describe the technical content of the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0027] The present invention designs an SDN-based streaming media QoE control system. The present invention combines the SDN software-defined network platform with the QoE control in streaming media transmission, and designs a streaming media QoE control system based on SDN. The characteristics of the influence of the network environment, through the use of BP neural network training to obtain weights, use the weights to calculate the QoE effect of each path, select a path with the best QoE effect, improve the quality of streaming media transmission, and make the QoE of streaming media transmission be improved to make better use of network resources.

[0028] figure 1 The overall structure of the system of the present invention is given, the whole system is divided into four parts, stre...

Abstract

The invention discloses a streaming media QoE control system based on an SDN, and belongs to the field of SDN flow control application. The control system includes a streaming media server, a streaming media client side, an OpenFlow exchanger layer, an SDN control layer and a data training module. According to the system, streaming media transmission is carried out with the software definition network (SDN) as a platform, streaming media QoE is controlled by means of a best path selection method based on a BP neural network, and the best user perception experience of the streaming media is obtained under the condition of limited network resources and in a complex network environment. According to the streaming media QoE control system based on the SDN, the SDN and the streaming media QoE control are combined, and network control resources are saved; meanwhile, the effect of the streaming media transmission is greatly improved, the utilization efficiency of the network is improved, the robustness of the network is ensured, and the system has a practical application value.

Description

technical field [0001] The invention relates to the field of software-defined networks, in particular to a streaming media QoE control system in the field of software-defined networks. Background technique [0002] With the development of mobile Internet and the decline of network tariffs, people's demand for high-quality video is increasing day by day, and streaming media can be broadcast while downloading, which is the most popular video transmission method at present, and the ultimate goal of video transmission is to provide A satisfactory QoE (Quality of Experience) for the user makes the user feel good about the received video. [0003] The traditional streaming media transmission system adopts the method of encoding video data and sending it directly to the network. It does not control the transmission in the network, and is only responsible for receiving, decoding and playing video data at the receiving end, and the network transmission environment is complex. It is ...
