Abstract

In order to deal with the problems of dynamic topology, link instability and limited resources in satellite networks, this paper studies the multi-path routing algorithm based on Software Defined Network (SDN). The algorithm centrally manages the satellite network through SDN, obtains the link delay, bandwidth, and node load of the satellite, constructs the Transmission Cost Model, and optimizes the data transmission path, so as to improve the network transmission reliability and reduce the transmission delay. The experimental results show that the algorithm is superior to the traditional Dijkstra and LCRA algorithms in reducing the average end-to-end delay, decreasing the packet loss rate and improving the network throughput.
