Abstract

A quality of transmission (QoT)-aware adaptive adjustment scheme of optical path transmission performance under software control is proposed. First, a mathematical model of optical path transmission performance adjustment is established. Based on it, a new device link quality equaliser (LQE) is built. Second, using a centralised controller, the LQE introduces devices with different compensation abilities into the optical path. Therefore, it becomes an all-optical mode node or an optical-electrical-optical (O/E/O) mode node adaptively. Then an adaptive and elastic adjustment can be conducted on the transmission performance of the optical path. Finally, an experiment is presented to show the feasibility and effectiveness of the proposed scheme.
