Abstract

Software-Defined Networking (SDN) enables flexible deployment and innovation of new networking applications by decoupling
and abstracting the control and data planes. It has radically changed the concept and way of building and managing networked systems, and reduced the barriers to entry for new players in the service markets. It is considered to be a promising solution providing the scale and versatility necessary for IoT. However, SDN may also face many challenges, i.e., the centralized control plane would be a single point of failure. With the advent of blockchain technology, blockchain-based SDN has become an emerging architecture for securing a distributed network environment. Motivated by this, in this work, we summarize the generic framework of blockchainbased SDN, discuss security challenges and relevant solutions, and provide insights on the future development in this field.
