Abstract: In order to solve the problem that the rise of new technologies such as big data and cloud computing weakens the coping ability of traditional optical network customers to experience (QoE), a QoE research scheme is proposed to carry out the (NFV) mapping computing request of network function virtualization under the framework of software-defined flexible optical network (SD-EON). The NFV mapping scheme adheres to the idea of standardized image segmentation mechanism (ND) and combines the characteristics of network service request according to the proposed QoE idea, and establishes multiple subgraph sequences from the network element set and link set which are suitable for global search and network service mapping request. Then a reliable subset of sequences is evaluated by intersection processing for the implementation of mapping operations. Finally, a simulation environment is constructed to investigate the mapping effect of QoE algorithm. The statistical data after frequent tests show that the QoE algorithm has a significant comparative advantage in the load layout of the whole network after VON mapping, and has good global and application.
