摘要
针对天地一体化网络需要支持大规模(亿级以上)节点接入的挑战,研究了天地一体化网络大规模动态编址技术。首先分析了天地一体化网络特有的编址需求,包括大规模容量、高动态适配、多业务承载以及资源受限适配等需求。然后在此基础上,提出了基于IPv4/IPv6的混合编址方案和基于广义四叉树的一体化可伸缩编址方案。基于IPv6的统一编址方案通过24位固定前缀、8位子网类型、32位子网ID和64位身份ID的结构设计,实现了对天地一体化网络的高效覆盖;基于地理位置信息的子网编址技术使地面、海洋等子网能够根据位置动态分配地址;基于广义四叉树的编址方案则通过可伸缩的地理编址机制,有效降低了对精确定位的依赖。研究结果表明,所提编址方案能够满足亿级节点接入需求,支持高效路由与安全可信传输,为天地一体化网络的建设提供技术支撑。
Addressing the challenge of supporting massive-scale(over 100 million)node access in the space-ground integrated network(SGIN),this paper investigates large-scale dynamic addressing technologies by first analyzing SGIN's unique requirements,such as massive capacity,high dynamic adaptation,multi-service bearing and and resource-constrained compatibility.Building on this,a hybrid IPv4/IPv6 addressing scheme and an integrated scalable addressing scheme based on the generalized quadtree are proposed.The unified IPv6-based addressing scheme employs a structured design—comprising a 24-bit fixed prefix,8-bit subnet type,32-bit subnet ID,and 64-bit identity ID—to achieve efficient SGIN coverage,while location-based subnet addressing allows dynamic address allocation for terrestrial,maritime,and other subnets according to their positions.The generalized quadtree-based addressing scheme further reduces reliance on precise positioning via a scalable geographic mechanism.Results demonstrate that the proposed addressing schemes support the access requirements of hundreds of millions of nodes,enable efficient routing and secure trusted transmission,and provide key technical foundations for SGIN construction.
