使用路由无关 LEO 卫星实现太空中可靠的低延迟路由

Reliable Low-Delay Routing In Space with Routing-Oblivious LEO Satellites

Stefano Vissicchio, Mark Handley

AI总结:

针对资源受限且路径持续变化的 LEO 星间激光网络,提出 STARGLIDER,将路径计算下放至地面站,使卫星路由无关,同时支持链路故障快速重路由与恶意地面站路径校验。

摘要:

利用星间激光链路,大型低地球轨道(LEO)卫星网络正在建设之中。这些网络有望提供低延迟广域连接,但可靠地路由此类流量十分困难,因为卫星资源非常受限且路径不断变化。我们提出 STARGLIDER,这是一种新型路由系统,将路径计算委托给地面站,而卫星保持路由无关,并在运行时不交换任何信息。尽管如此,STARGLIDER 卫星仍能有效支持可靠性原语:当链路发生故障时,它们会通过近优路径快速重路由数据包,并验证潜在恶意地面站发送的数据包是否遵循合理路径。

英文摘要:

Large networks of Low Earth Orbit (LEO) satellites are being built using inter-satellite lasers. These networks promise to offer low-latency wide-area connectivity, but reliably routing such traffic is difficult, as satellites are very resource-constrained and paths change constantly. We present STARGLIDER, a new routing system where path computation is delegated to ground stations, while satellites are routing-oblivious and exchange no information at runtime. Yet, STARGLIDER satellites effectively support reliability primitives: they fast reroute packets over near-optimal paths when links fail, and validate that packets sent by potentially malicious ground stations follow reasonable paths.
