摘 要：The Software-Defined Networking (SDN) paradigm is typically applied to data center and enterprise networks. We argue that SDN is also promising for rural wireless networks, especially those in developing regions. Operating a rural network in the developing world means coping with unpredictability, low profit margins, and resource constraints; the increased flexibility and simplified management that software-defined networks provide are a major benefit in this context.
