摘要

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 the characteristics such as the dynamic network topology and limited bandwidth, CPP is quite complex in satellite networ...
