摘　　要：为实现更加智能化的节能设计,提出一种新的舰船主干网络动态负载均衡方法与节能机制。对舰船主干网络系统进行能耗建模。在建模中将舰船主干网络系统网络拓扑直接模拟为一种有向图,不对休眠控制器与其相关链路进行考虑,仅对休眠交换机相关配置端口进行考虑。根据构建的能耗模型,设计一种分配算法,对服务器任务进行合理分配。设计一个由多个组件构成的舰船主干网络节能机制,具体包括决策组件、预测组件等组件。参照舰船主干网络的通信协议标准部署实验仿真场景,对设计方法进行仿真验证。验证结果表明设计方法能够实现动态负载均衡,对于用户流量的承受能力与可调节性都较强;端口休眠比例整体较高,最高可达95.9%,休眠比例波动幅度较小,以及能耗整体较低,达到了很好的节能效果,说明设计方法达到了设计目标。In order to realize more intelligent energy-saving design,a new dynamic load balancing method and energy-saving mechanism of ship backbone network are proposed.The energy consumption of ship backbone network system is modeled.In the modeling,the network topology of the ship backbone network system is directly simulated as a directed graph,and the sleep controller and its related links are not considered,but only the related configuration ports of the sleep switch are considered.According to the energy consumption model,an allocation algorithm is designed to reasonably allocate the server tasks.An energy-saving mechanism of ship backbone network composed of multiple components is designed,including decision-making component,prediction component and so on.According to the communication protocol standard of ship backbone network,the experimental simulation scenario is deployed to verify the design method.The verification results show that the design method can realize dynamic load balancing,and has strong bearing capacity and adjustability for user traffic;The overall dormancy ratio of the port is high,up to 95.9%.The fluctuation range of the dormancy ratio is small,and the overall energy consumption is low,which has achieved a good energy-saving effect,indicating that the design method has achieved the design goal.
