基于虚拟化技术的数值仿真与中央监控系统网络设计

“数值仿真与中央监控系统”作为国家大科学工程项目“空间环境地面模拟装置”的分系统，为装置提供数据采集、实验和安全监控、集中展示、数据存储、运行管理、数值仿真、数据共享以及配套系统的监管等服务。文章基于各类业务在网络中的承载需求，针对系统网络涉及业务种类繁多、数据量大、网络规模复杂等特点，采用星型拓扑结构，各节点采用双设备部署，防火墙采用Acitve-Acitve路由方式部署，利用网络虚拟化技术对网络进行横向融合和纵向隔离，构建了多业务统一承载的数值仿真与中央监控系统网络。该设计简化了网络规划，提升了网络带宽，增强了网络的可靠性和安全性，最终实现在一张物理网络中为各类实验业务提供差异化网络服务。

Network design for numerical simulation and central monitoring system based on virtualization technology

As a sub-system of the space environmental ground simulator for the National Major Science and Engineering Project, the numerical simulation and central monitoring system provides various services such as the data acquisition, the experimental monitoring and control, the safety monitoring and control, the centralized display, the data storage, the operation management, the numerical simulation, the data sharing, and the system maintenance. Based on the loading requirements of all kinds of tasks in the network, and in view of the characteristics of the system network involving various services, a large amount of data and a complex network scale, the star topologyis adopted. Each node is deployed with dual devices, and the firewalls are in Acitve-Acitve routing deployment. Meanwhile, the horizontal integration and the vertical separation of the network are implemented by the network virtualization technology. Thus, the numerical simulation and central monitoring system network with multi-service unified load is constructed, with simplified network layout, improved network bandwidth, and enhanced network reliability and security, to provide differentiated network services for various experiments in one physical network.
