摘要

天地一体化信息网络中具有高度动态性的低轨卫星导致地面用户设备在低轨卫星之间不断切换，使得低轨卫星接入用户所获取的IP地址不断改变，难以稳定。对天地一体化信息网络中无状态地址自动配置进行研究，针对低轨卫星星座中地面设备不断切换低轨卫星的场景，提出一种IPv6无状态地址自动配置与重复地址检测机制，通过引入地面位置信息和卫星轨道信息缩小重复地址检测的范围，从而有效降低重复地址检测的信令开销。

Abstract

LEO (Low Earth Orbit) satellites with high mobility in space-integrated-ground information network cause ground user terminals change connected satellites continuously

so user terminals can't keep stable IPv6 addresses.SLAAC (Stateless Address Auto-Confi guration) in space-integrated-ground information network to provide stable IPv6 addresses was investigated

and an eff ective SLAAC and DAD (Duplicate Address Detection) mechanism was proposed.Aiming at the scenario where the ground equipment in the LEO satellite constellation constantly switches the LEO satellites

an IPv6 stateless address automatic confi guration and duplicate address detection mechanism was proposed.The scope of duplicate address detection was reduced by introducing ground position information and satellite orbit information

thereby eff ectively reduced signaling overhead for duplicate address detection.
