Talk Title: Power Control of Optical Networks with Time-Delay
Slides: 9-2.ppt
Abstract: The effects of time-delay on the stability of optical communication networks are studied. A link level power control scheme adjusts the optical signal to noise ratio (OSNR) values of the signals toward the OSNR channel optimization problem. A game-theoretic based control algorithm is utilized to achieve predefined OSNR targets. Time-delay is incorporated into the closed loop system for the general case in which every link has a unique time-delay. Sufficient conditions for stability are derived under any arbitrary time-delays and network configurations.
