Optimization of Quality of Experience through File Duplication in Video Sharing Servers
This addresses QoE issues for video consumers and network operators, but it is incremental as it builds on existing file duplication methods.
The paper tackles the problem of poor Quality of Experience (QoE) for short video consumers due to long distances from servers by optimizing file allocation through duplication to bring files closer to users, resulting in improved QoE with analytical discussion of costs versus gains.
Consumers of short videos on Internet can have a bad Quality of Experience QoE due to the long distance between the consumers and the servers that hosting the videos. We propose an optimization of the file allocation in telecommunication operators content sharing servers to improve the QoE through files duplication, thus bringing the files closer to the consumers. This optimization allows the network operator to set the level of QoE and to have control over the users access cost by setting a number of parameters. Two optimization methods are given and are followed by a comparison of their efficiency. Also, the hosting costs versus the gain of optimization are analytically discussed.
