In order to meet the huge bandwidth requirement of cloud video, a practical scalable video coding (SVC)-based scheduling algorithm is proposed in this paper. The strategy fully considers the characteristics of scalable video bit stream. It accesses the users with basic layer bandwidth at first by the control criteria of maximization the number of service users according to the waiting time of the users, and then assigns enhancement layer bandwidths to the accessed users when the bandwidth remaining is not sufficient to access new users. The simulation results show that the proposed strategy could greatly shorten the average waiting time of users, increase the fairness index of bandwidth allocation and improve the average customer satisfaction efficiently compared with the First Come First Serve (FCFS) algorithm.
