Abstract：
Computer network system is an important support for the FY satellite ground segment. This paper introduces the architecture and characteristics of the computer network platform of the FY satellite ground segment from four aspects including computing resource pool, storage resource pool, network system, and management software. Resource scheduling, parallel computing, cloud computing, big data and other technologies are used in the computing resource pool to realize the full and efficient use of computing resources. The storage resource pool uses storage virtualization and distributed storage technologies to realize the sharing of storage resources. The software-defined network technology ensures the efficiency and flexibility of the network system. Integrated intelligent maintenance system and typical application analysis and optimization software have been developed to achieve unified management and continuous optimization of the system. The actual operation shows that the platform is efficient and reliable, and it supports the satellite data reception, processing, archiving, service, application, and satellite on-orbit management efficiently.
