Title: Optimal routing algorithm based on user experience estimation model
Abstract: As a fast-growing contributor to Internet service,online videos make ISPs and video providers pay more attention to the Quality of user Experience(QoE).The existing routing algorithms could only guarantee that parameters of path such as delay and jitter,in accordance with the demands of Quality of Service(QoS) restriction.However,they are not able to reflect the QoE-related information directly.As a result,these kinds of algorithms cannot meet the demand of showing QoE.This paper proposed a QoE-optimal routing algorithm called QoE_DSP,based on QoE estimation model.By taking advantage of two properties of QoE parameter,decomposability and nondecreasing characteristics from the analysis on relationship between QoE and QoS,the authors designed QoE_DSP,which owned a polynomial time complexity of(V log V+E).According to the experiments and results analysis,this algorithm can guarantee the selected path meets the demand of QoE,while it also has a strong computational scalability.
