The launch vehicle ground test and control network is the backbone for transmitting ground information. The requirements of this network are efficient and reliable. However, with the development and application of a new generation of rockets, the requirements for real-time performance are getting higher and higher, and the amount of data in the system is soaring. The existing rocket network indicators can not meet the demand of the new generation of rockets for the ground network. Therefore, this paper proposes a ground-based measurement and control network based on VSS and SSM new technology. This network improves the network self-healing time by applying VSS technology, virtual switching, simplifying loop architecture and routing protocol, and adopting SSM technology and multicast address. Designed to avoid multicast useless superposition, greatly reducing the CPU resource consumption of the switch and ensuring normal transmission network transmission.
