【Abstract】 In order to overcome the complexity and long-delay of the traditional shared buffer management,a polling queue management method based on the average information delay time was proposed on the study of buffer control in ATM networks. This method can consider all kinds of services′ need for time delay and loss probability together, it also can satisfy the quality of service by guaranteeing the throughput of high priority cell without serious cell loss of low priority cell for too long time delay.更多还原
