Photonics also enables diverse technologies to be integrated into a seamless communications platform. Dynamic processing chain framework provides the flexibility and future-proof capability via reconfigurability and componentization. Physical-layer-awareness offers support for automated adaptation and intelligent configuration of the data plane in response to the dynamic conditions of the physical layer. Crucial functional blocks in this awareness are: efficient estimation of physical impairments of the components and links; an effective dynamic impairment monitoring mechanism; and proficient adaptation to either maximize or optimize performance.Though the architecture encompasses both optical transport network (OTN) and photonic radio, this dissertation focuses more on the OTN. Central themes of OTN in this dissertation include relating Q-factor with various optical impairments from the perspective of an end-to-end optical path, and extending physical layer awareness with impairment routing.

There is an ongoing evolution of technology towards network convergence and ubiquitous information society in which users have broadband access to information resources and services anywhere, anytime.
