42 Cognitive optical node architecture On the top level, cognitive service plane, cognition can create a self-optimized BW virtualization (buffer self-management and re-configuration) to suit service requirements under node conditions (buffer availability and structure). On control plane layer, distributed signalling and routing protocols can also be re-configurable, selfmanaged and self-healing by modifying protocol interactions, state machines and routines to reserve resources and disseminate availability information. At the MAC layer the transport module can support a re-configurable MAC protocol by supporting adaptive bandwidth allocation e.g. under different characteristics of network load, number and type of applications transferred, type of available PHYs. The O/E transponder consists of a cognitive PHY able to re-configure, adapt and re-purpose internal functions. Bit-rate, symbol rate, modulation format, wavelength(s) used, power level, continuous/burst mode operation can be automatically adjusted to respond to environmental stimuli.
