DHBAM: dynamic and hierarchical bandwidth allocation method
DHBAM:一种动态层次式带宽分配方法

According to the different collaborative service requirements of data transmission in collaborative virtual environment, this paper presented a dynamic and hierarchical bandwidth allocation method. This method could dynamically adjust bandwidth allocation based on service level by using a bandwidth resource reservation method in the active router, so as to provide high-quality data transmission for collaborative users. The simulation results show that the users of H, M, L levels can get the corresponding bandwidth according to their levels in the condition of load variation. The analysis show that this method can assure the quality of the data information transmission among users in the situation of system load variation.
