Real-time Scheduling Algorithm for the Multicast and Broadcast Service

In view of the delay problem in the multicast and broadcast services, a real-time scheduling algorithm is proposed. By constructing the simulation scene of the multicast and broadcast services transmission, the scheduling algorithm to guarantee the quality of service QoS (Quality of Service) for real-time multicast services is realized, and the performance is compared with the maximum throughput algorithm and the time delay algorithm. The priority function of the scheduling is defined by analyzing the multi effect factor to guarantee the performance. In the simulation, the performance of the scheduling algorithm is evaluated by analyzing the delay and throughput indicators. The simulation results show that the proposed real-time scheduling algorithm has good delay and throughput performance. It is suitable for the transmission of multimedia services, especially the multicast traffic with higher delay requirements.
