Abstract :
We analyze the effects of time-delay in optical communication networks. A link level power control scheme adjusts the OSNR value of the signals toward channel OSNR optimization. We utilize the model from L. Pavel (2006) along with its game-theoretic based control algorithm. We incorporate time-delay into the closed loop system, for the general case where every link has a unique time-delay. We derive sufficient conditions for stability under arbitrary time-delays and network configurations.
