针对协作式虚拟环境中,协作对象对数据报文的传送有着不同服务要求,提出了一种基于协作层次的动态层次式带宽分配方法。该方法通过带宽预留的方式,能根据协作服务等级和网络链路状况,在主动路由器上对网络带宽进行动态调整,为协作用户提供了高质量的带宽传输保证。仿真结果显示,H、M、L层次的用户由于级别不同而在网络负载变化时能得到适合自身层次的带宽。其分析表明,该方法在系统网络负载变化时能保证不同协作用户之间的数据信息传输的质量要求
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
