%X The traditional open loop scheduling algorithms perform poorly in open real time systems whose workloads vary unpredictable dynamically because the open loop refers to the fact that once schedules are created they are not adjusted based on the system workloads.A dual close-loop feedback scheduling algorithm is proposed to improve total bandwidth server in EDF scheduling which is widely used in open real time systems.The algorithm adjusts the resource assignation for different kinds of tasks based on feedbac...
