基于云计算虚拟化技术的船舶航海信息服务平台

Design of ship navigation information service platform based on cloud computing virtualization technology

采用KVM虚拟化系统的内核单元,调用并驱动虚拟机、构建虚拟节点、生成虚拟网络环境,通过QEMU处理器完成虚拟机对应I/O磁盘运行,将虚拟网络提供给虚拟管理层应用,通过虚拟化技术转换舰船航海信息服务平台内的物理资源为资源池,并整合物理资源层中同类资源,将同类构资源池提供给事物管理层;通过事物管理层调控将所有的航海信息传送应用至服务层,通过应用服务层为用户提供舰船航海信息服务。实验结果表明,该平台具有较好的信息传输完整性与交互性能,构建网络环境消耗时间低。

The kernel unit of KVM virtualization system is adopted to call and drive the virtual machine,build the virtual node and generate the virtual network environment.The corresponding I/O disk operation of the virtual machine is completed through QEMU processor,the virtual network is provided to the virtual management application,and the physical resources in the ship navigation information service platform are transformed into resource pool through virtualization technology,Integrate the similar resources in the physical resource layer and provide the similar structure resource pool to the thing management layer;All ship navigation information is transmitted and applied to the service layer through the regulation of the affair management layer,and the ship navigation information service is provided to users through the application service layer.The experimental results show that the platform has good information transmission integrity and interactive performance,and the construction of network environment consumes low time.
