A quality-of-service(QoS)aware scheme,called precautionary performance monitoring,is proposed to solve the optical impairments and congestion control in coherent optical orthogonal frequency division multiplexed(CO-OFDM)networks.The centralized path computation element(PCE)extensions based on the QoS level are applied to optical performance monitoring in this letter.
