Furthermore, a low-load survivable routing protocol called Virtual Snapshot Routing Protocol is proposed for LEO satellite networks. The proposed protocol not only reduces the routing computation and storage overheads, but also provides good routing survivability under random satellite failure. The experimental results confirm our conclusions.
