| Περιγραφή: | Software-defined networking (SDN) logically separates the control and data-forward planes, which opens the way to a more flexible configuration and management for low-Earth orbit satellite networks. A significant challenge in SDN is the controller placement problem (CPP). Due to characteristics such as the dynamic network topology and limited bandwidth, CPP is quite complex in satellite networks. In this paper, we propose a static placement with dynamic assignment (SPDA) method without high bandwidth assumption, and formulate it into a mixed integer programming model. The dynamic topology is taken into account by effectively dividing time snapshots. Real satellite constellations are adopted to evaluate the performance of our controller placement solution. The results show that SPDA outperforms existing methods and can reduce the switchcontroller latency in both average and worst cases This work was supported in part by the National Key Research and Development Program of China under Grant 2016YFB0502402, and by the Agencia Estatal de Investigaci´on of Spain under project PID2019-108713RBC51/ AEI/10.13039/501100011033.
