a new algorithm for guaranteed delay in diffserv architecture

Qos support for the internet new applications is necessary to meet end-to- end requirements such as bandwidth, delay , jitter and packet loss. In this paper we have focused on diffserv architecture to improve its accuracy we proposed a new algorithm to schedule differentiated buffers in routers, using adaptive model predictive control as the controller. simulation results show that the new algorithm can be used as a solution for the scheduling problem to guarantee Qos parameters like absolute delay proportional delay and jitter
