With the development of computer systems, the realtime systems with different kinds of real-time applications and non-real-time applications are becoming more and more popular. At the same time, more and more multimedia applications make real-time system to support QoS. Based on the real-time systems, the paper proposes a model of Linux-based open real-time systems with QoS support. Firstly, the paper analyzes real-time systems and QoS. Secondly, a windows-constrained CBS is proposed. Then it proposes the scheduling framework of Linux-based open real-time systems. Finally, the experiment results are showed.
