Reliable Data Delivery in Software-Defined Networking: A Survey

Software-defined networking is a network paradigm which has shifted the intelligence of the underlying network interface to an independent control plane. The controller acts independently from the data plane. This isolation of the plane brings about greater opportunities but with a challenge of attaining higher reliability and optimum energy consumption in packet delivery. This paper aims at identifying approaches that improve the performance of the software-defined networking (SDN) with increase in reliability, specially required for real-time data delivery.
