Abstract：There are several problems existing in streaming media service in library, such as mass users and the unbalanced load. The paper researches a variety of load balancing methods, then presents a dynamic load balancing method. The method calculates utilization rates of each service by using dynamic feedback principle,which combines with historical data to select the suitable sampling interval, then divides appropriate space of resources utilization rate according to weighted round-robin scheduling and interval random round-robin scheduling, finally achieves concurrent access to resources for the numerous users.
