A Study on the Adaptation of the Firefly Algorithm for the Synchronization between Multiple Controllers in SDN Environment

Arising of IoT(Internet of Things) and Big data, rapid increasing of Information Technology utilization on various fields and spreading of services such as SNS(Social Networking Service) and Cloud Computing led to increase in demand for a various network equipment. device, protocol and policy. This kind of changes needs new generation of network. Correspond with this, the needs for new format of Internet is arise and this makes interest in the SDN(Software Defined Network) which is one of the future Internet technology. SDN consist in centralized environment. To solve the problems occurred in this kinds of format, the concept of Multiple Controllers based SDN is appeared. To dealing with the important synchronization issues in Multiple Controllers based SDN, In This paper, we propose an adaptation of the Firefly Algorithm for the Synchronization between Multiple Controllers.
