Abstract: We proposed a new routing algorithm for doublelayer networks based on low earth orbit(LEO) and geostationary earth orbit (GEO) constellations. The algorithm used the mesh topology of LEO satellites and their intersatellite links to calculate routing. The mechanism of congestion avoidance and packet classification was used to optimize the algorithm. It solved the problem of network congestion caused by large traffic in satellite networks. The simulation results show that the proposed method reduces the average endtoend delay and average packet loss rate, so network performance is improved.
Key words: satellite network, traffic, congestion avoidance, routing algorithm, network topology
