A survey of Blockchain technologies applied to software‐defined networking: Research challenges and solutions

Abstract Software‐Defined Networking (SDN) brought a groundbreaking idea to facilitate network system management by decoupling and abstracting the Control plane and Data plane of traditional networks. The centralised control offers network administrators many benefits such as a global view of the ne...
