Buffered crossbar switches are now becoming very attractive for the high performance packet switches. An architecture that combines the VOQ architecture and internal buffers can eradicate the HOL problems and reducing the output contention. The architecture predominance and the internal distributed arbitration can fit the broadband satellite networks very well. We propose a new scheduling scheme named Rate Durative (RD), which a VOQ is served continuously at the same time considering its priority level under certain rules. Our scheme was shown to handle traffic more efficiently and better than previous schemes. In addition, this scheduling scheme also supports QoS very well
