Dynamic and static controller placement in Software-Defined Satellite Networking

Software-Defined Satellite Networking (SDSN) [1], similar to Software-Defined Networking (SDN) [2], has emerged as a new paradigm that offers the programmability required to dynamically configure and control a satellite network. As SDSN is large-scale network, recent proposals have advocated deploying multiple controllers that work cooperatively to enhance performance and scalability [3,4]. Nonetheless, this approach introduces a new problem:...
