Abstract: According to the characteristic of LEO/MEO satellite constellation, a rapid and reconstructable routing protocol was proposed. At the same time, the model of the algorithm was simulated and features were analyzed. This protocol not only reduces the duration for end-to-end path establishment significantly, but also the multi path capability provides the flexibility for reliable transmission and load balance in satellite networks.
