Ubiquitous Video Transmission Scheduling Supported by Computing Power Network

The explosive growth of video data volume, the increasing diversity of video forms, and the ubiquity of video services are the three main characteristics of the development of current video communication technology. This fact will undoubtedly lead to two main problems. The first is that the traffic burden of the core network is difficult to offload, and the second is that, the video transmission conflict is difficult to coordinate. In order to alleviate these two problems, we propose a ubiquitous video scheduling scheme, supported by computing power networks. Specifically, we first propose a hierarchical video coding and decoding model to enhance the flexibility of video content deployment and transmission; Secondly, we propose a service-oriented good-put model with the consideration that the diversity transmission parameter constraints of different video services; Finally, with the support of computing power network, on the one hand, through task decomposition, the “fragmented” network resources can be utilized effectively, and on the other hand, through global detection and real-time perception of network status, accurate deployment of video content and efficient scheduling of network resources can be achieved. Simulation experimental results verify the effectiveness of the proposed scheme in terms of core network traffic offloading, good-put improvement, and network resource utilization rate improvement.
