摘　　要：随着空天技术的迅猛发展以及商业航天蓬勃兴起,国内外低轨星座计划层出不穷,陆海空天融合成"一张网"成为未来网络发展的重要方向。路由交换是实现空间组网的关键技术之一,也是空间网络与地面网络融合的核心内容,因此亟需开展空间路由交换体制研究。在简要介绍空间网络架构及特征的基础上,根据空间路由交换体制的关键特征进行分类,并以典型卫星通信系统为例,阐述已有空间路由交换体制的核心机理、存在的问题及发展趋势,提出“多模态路由交换”与“统一分组控制网”的发展设想,以期为空间网络研究提供有价值的建议。With the rapid development of aerospace technology and the booming of commercial spaceflight,domestic and overseas low-orbit satellite constellation projects have emerged one after another,and the"one network"integrated by ground,sea,air,and space networks has become an important direction of future network development.Routing and switching is one of the key technologies to realize space networking,and also the core content of the integration between space network and ground network.Therefore,it is urgent to cany out the research on space routing switching system.Based on the brief introduction of the space network architecture and its characteristics,this paper classifies the space routing and switching systems according to the key characteristics.Then taking the typical satellite communication system as an example,this paper illustrates the core mechanism,existing problems,and development trend of the existing space routing switching system,and then proposes the development ideas of"multimodal routing/switching architecture" and"unified packet control network" for providing valuable suggestions to space network research.
