SDN is a new network operation and management solution, which decouples the control and data planes in a communication network. SDN makes it easier for network administrators to create, modify, and manage dynamic networks by abstracting low level functions and network structure. Generally, SDN uses a centralized controller, which offers a global view of the entire network. This new feature offers the flexibility for administrators to define the strategies in terms of how the network flow is forwarded on a software level. With the advancing of the research on SDN, however, distributed SDN controllers are also introduced by researchers. One reason for the emerging of distributed SDN controller is: it can address the problems of scalability, reliability, and performance issues that a centralized SDN controller suffers from acceleration
