Optimised optical burst aggregation by employing dynamic state-space feedback gain scheduling controller

This paper describes the design of a dynamic state-space feedback gain scheduling controller for OBS burst scheduling. It can meet upper layer application requirements, while protecting the network from incurring severe burst loss and end-to-end delay. Through the use of gain scheduling to provide dynamic shifting between different models, the controller provides more accurate modelling than a single linear system approximation. Moreover it employs a MIMO system to consider the interaction between the scheduler parameters, i.e. TimeOut and MaxLenght in order to provide more accurate modelling than a multiple SISO system approximation. Finally the proposed controller model is verified by the use of OPNET simulation.
