As the popular technology of communication industry, SDN is based on the separation of the control plane and data plane, also introducing the programming between network and service. SDN will be the solutions of large capacity demand, high construction costs, inflexible provisioning and etc. bringing by rapid development of internet technology. Although SDN is still on the primary stage, it will make profund impact on the optical transport network, and actively study is necessary.
