网络化综合化的天地一体化信息系统探讨

针对天地联网中空间与地面网络节点的信息高效互通、交换及应用需求,利用电子信息综合化技术实现高度综合化的多功能通用平台,构建天基以及地面系统"资源池",结合SDN(Software Defined Network,软件定义网络)架构、网络协议与路由网关,将有效解决网络中由于物理界限造成的信息阻隔,实现物理资源与边界虚拟化、信息流程智能化的天地一体化天基信息系统,提高天基信息资源利用率、信息按需定制及高效共享能力.结合天基信息系统发展趋势,探讨了天地一体化信息系统的网络化、综合化应用建议和研究重点,梳理了天、地节点综合化、网络化的关键技术方向.

Networked and Integrated Space-Ground Information System

Application needs of effective information delivery and exchange between space and ground network nodes in space-ground network, an integrated multi-function common platform based on information integration technology was implemented and a resource pool for space-based and ground systems was constructed using Software Defined Network (SDN)architecture,network protocol,and route gateway in order to remove information block caused by physical border around nodes within network. It's an integrated space-ground information system with function and physical resources virtualization and intelligent information flow. It enabled improvement of space-based information resource utilization,information tailoring by demand and effective information sharing capability. Based on space-based information system development trends,application suggestions and development focus of in-tegrated space-ground information system are proposed,and key technical development directions are discussed.
