[Abstract] In order to address cost optimization problems of virtual optical network (VON) mapping, software-defined optical network (SDON) architecture and VON mapping architecture are proposed. With the VON mapping model, the VON mapping strategies and the coordinated virtual nodes and virtual links mapping approaches are proposed to reduce the network cost. Network cost optimization problems are solved by the proposed VON mapping approaches. Therefore, some important technical supports will be provided by employing the proposed VON mapping models and approaches in the future.
