摘　　要：针对天基综合信息网(SBN)稳定性比较差的缺点,提出一种基于角色控制的动态带宽分配算法(RCBA),基站将服务连接的带宽请求按照优先级分类,在设定预留带宽的基础上允许抢占带宽。仿真实验表明,相比传统带宽分配算法,RCBA算法降低了时延,减少了丢包率,较好地满足了天基网的应用需求。Space-based integrated information networks were of relatively poor stability.In view of this,a Role-Control-based dynamic Bandwidth Allocation（RCBA） algorithm was presented.The base station classified the bandwidth requests according to the priority,and permitted the bandwidth occupation on the basis of reservation bandwidth.The theoretical analysis and simulation results prove that,compared with the traditional bandwidth allocation algorithm,RCBA algorithm reduces the delay and the packet loss rate,and preferably meets the requirements of applications in Space-Based Network（SBN）.
