With the expansion of satellite constellation,routing techniques for small-scale satellite networks have problems in routing overhead and forwarding *** paper proposes a vector segment routing method for large-scale multi layer satellite networks.A vector forwarding path is built based on the location between the source and the *** packets are forwarded along this vector path,shielding the influence of satellite motion on routing ***,a dynamic route maintenance strategy is *** a multi layer satellite network,the low-orbit satellites are in charge of computing the routing tables for one area,and the routing paths are dynamically adjusted in the area in accordance with the *** medium-orbit satellites maintain the connectivity of vector paths in multiple segmented *** forwarding mode based on the source and destination location improves the forwarding efficiency,and the segmented route maintenance mode decreases the routing *** simulation results indicate that vector segment routing has significant performance advantages in end-to-end delay,packet loss rate,and throughput in a multi layer satellite *** also simulate the impact of routing table update mechanism on network performance and overhead and give the performance of segmented vectorrouting in multi layer low-orbit satellite networks.
