【Abstract】 This study proposes a dynamic grouping algorithm based on SLA, which can effectively solve the problems of low bandwidth utilization rate and difficulty in guaranteeing delay. The proposed algorithm could make dynamic change according to actual condition and realize the authorization in advance of the next cycle, thus optimizing the bandwidth time slot. By simulating the algorithm with OPNET, comparing with other schemes, it proves that the algorithm has the better bandwidth utilization and characteristics of lower system time delay.更多还原
