基于VSS及SSM的运载火箭地面测发控网络系统设计

运载火箭地面测发控网络是传输地面信息的中枢,对此网络的要求是高效和可靠。但是,随着新一代火箭的研制及应用,对实时性的要求越来越高,系统内数据量的激增,现有火箭网络指标满足不了新一代火箭对地面网络的需求。提出一种基于VSS及SSM新技术的地面测发控网络,通过应用VSS技术,虚拟切换,简化环路架构及路由协议,提高网络自愈时间,通过采用SSM技术及组播地址设计,避免组播无用叠加,极大地降低对交换机CPU资源消耗,保证交换网络传输正常。

VSS and SSM based Ground Test and Control Network System for Launch Vehicle

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.
