摘　　要：为实现空中信息分发平台对战场多任务网络带宽资源的有效管理,在战术互联网资源管理模型中,提出一种等级优先动态带宽分配(classification prioritized dynamic bandwidth allocation,CPDBA)算法。该算法改进了基于网络效能最大化的带宽分配方法,优化了对指数效能业务的调度策略。仿真结果表明,该算法不但能够使相同带宽资源产生更高的任务价值,而且在网络过载时可以确保高优先级业务的服务质量,从而有效解决了多任务网络的链路带宽竞争问题。To meet the requirements of bandwidth scheduling for airborne information dissemination in military multi-mission network,a classification prioritized dynamic bandwidth allocation（CPDBA）algorithm is proposed. The dynamic bandwidth allocation mechanism is improved by maximizing the total mission-value and the scheduling policy for exponent-utility requests is optimized.The simulation results show that CPDBA algorithm not only could increase the total mission-value of multi-mission network significantly,but also ensure the quality of service（QoS）for most critical requests,which resolves the bandwidth contention effectively in multi-mission network.
