It is necessary to provide priority-based data transfer on HFC networks. In this paper, we propose a scheme that can support priority-based bandwidth contention. The scheme is easy to realize. In addition, the overhead in the headend is extremely low. We use simulation to verify that the scheme we proposed can indeed make high-priority bandwidth requests have greater possibility to succeed than low-priority bandwidth requests.
