Abstract
Some characteristics of deep space communication network are well known, such as nodes limited resources, long communication delay and nearly no guarantee for the transmission quality, this paper proposes a dynamic QoS routing mechanism for deep space network based on SDN architecture, which uses heuristic algorithm to discover and update the routing paths dynamically. According to the changing of network topology and performance constantly, the algorithm can select the optimal path according to the current real-time network performance state. In case of the characteristics of deep space network, the heuristic algorithm makes a lot of improvements from the global point of view, so that it can be more suitable for deep space network environment. Finally, the paper verified the performance of the algorithm by simulation experiments.
