摘　　要：为了保证军事指挥的及时性和精确性,需要在端到端的用户连接上,为各种指挥控制业务预留带宽以保证其服务质量。然而,当前指挥控制网络中,不同通信设备和手段能够提供的带宽资源差异较大,采用传统的均匀带宽预留方法,会造成瓶颈链路带宽迅速耗尽,从而限制网络能够容纳的用户连接数量。为了解决这一问题,提出了一种非均匀的带宽预留方法,其能够在保证端到端服务质量的同时,根据不同链路的可用资源,在每一跳预留最优的带宽,从而减少瓶颈链路上的带宽消耗,提升网络能够容纳的用户连接数量。为了证明提出方法的可行性,基于Openflow协议提供的meter table机制,设计了一种自动化的非均匀带宽预留实现机制。最后,实验和仿真结果证明,提出的方法,在指挥控制网络的大多数应用场景下,均能够实现比传统带宽预留方法更好的性能表现。In order to ensure the timeliness and accuracy of military command,it is necessary to reserve bandwidth for various command and control services to ensure the quality of service on the end-to-end user connection.However,in the current military command and control network,different communication devices and means can provide different bandwidth resources.The traditional uniform bandwidth reservation method will cause the bottleneck link bandwidth to be quickly exhausted,thereby limiting the user connections that the network can accommodate quantity.In order to solve this problem,this paper proposes a non-uniform bandwidth reservation method,which can guarantee the end-to-end quality of service and reserve the optimal bandwidth for each hop according to the available resources of different links.Thereby reducing the bandwidth consumption on the bottleneck link and increasing the number of user connections the network can accommodate.In addition,based on the meter table mechanism provided by Openflow protocol,this paper designs an automatic non-uniform bandwidth reservation implementation mechanism,which proves the feasibility of the proposed method.Finally,the experimental and simulation results show that the proposed method can achieve better performance than the traditional bandwidth reservation method in most application scenarios of the military command and control network.
