Conclusion

Circuitous routing is a significant challenge faced by mobile satellite networks, which is largely caused by the design of a single-anchor session. In this paper, we propose an advanced mobile satellite network architecture. We introduce SkyOctopus, which avoids circuitous routing through multi-anchor connections and achieves low-latency access for users with a fine-grained anchor point selection strategy. Furthermore, we construct a prototype of SkyOctopus and conduct experiments to evaluate its performance. The results show that our solution can reduce end-to-end latency by up to 53% and session establishment time by 86%.

路由迂回（Circuitous routing）是移动卫星网络面临的一项严峻挑战，其主要由单锚点会话的设计所导致。在本文中，我们提出了一种先进的移动卫星网络架构。我们引入了SkyOctopus架构，它通过多锚点连接避免了路由迂回，并以一种细粒度的锚点选择策略为用户实现了低时延接入。此外，我们构建了SkyOctopus的原型系统，并进行了实验以评估其性能。实验结果表明，我们的方案可将端到端时延最高降低53%，并将PDU会话建立时间减少86%
