In order to improve the uplink channel resource utilization of broadband satellite network,while guarantee the quality of different multimedia services,it needs to adopt an appropriate media access control protocol.Burst target demand assignment multiple access(BTDAMA) significantly reduced the wait time of self-similar services,and improved the resource utilization.But it did not distinguish the business type,did not guarantee the quality of high-priority services,and caused a certain degree of the waste of resources.In this paper,an assignment algorithm of bandwidth is proposed,which is on the basis of business priority.By using different distribution scheme for different service types,it is useful to guarantee the quality of all kinds of business,and improves the resource utilization.
