An approximated quadratic programming optimization is proposed to determine a model predictive controller to guarantee end-to-end delay in the DiffServ architecture. The proposed algorithm, called the suboptimal model predictive control scheduler (SMPCS), regulates the service rates of aggregated traffic classes dynamically, such that some constraints on proportional or absolute delay can be guaranteed...
This paper applies model based predictive control (MFC) to the scheduling problem in routers to guarantee QoS in DiffServ architecture. Model predictive control is a form of control in which the current control action is obtained by solving a finite horizon open-loop optimal control problem at each sampling interval. It intrinsically supports constraints handling and smoothens the control action over...
