摘要：

The mismatch of transmission ability causes the discontinuous transmission of video services in fiber-wireless access network, aimed at this problem, an QoE-aware video distribution mechanism was proposed. According to the structural characteristics of fiber-wireless access network, link state information and scalable video coding structure was considered, a QoE evaluation mode was established, and the particle swarm optimization algorithm was used to select optimal video transmission rate. Then the node transmission capacity and the node matching degree was analyzed, transmission path for the services was selected, so as to ensure the reliable transmission of services. The results show that the proposed mechanism can effectively improve the utilization rate of network resources and reduce network congestion while improving the quality of the user experience. © 2018, Editorial Board of Journal on Communications.
