As a new paradigm, software-defined networks (SDNs) are becoming increasinglypopular in the network world. From the available research, it can be concluded that SDN multi-domain environments have been under-protected. In areas where security was not a primary concern, management andpoliciesreceived the vast majority of attention. Previous studies have proposed a "distributed SDN Supervisory Controllers in Multi-Domain Environment" but still suffer from an operational count limitation. An improved framework for distributed SDN supervisory controllers operating in a multi-domain environment is the main focus of this paper. Additionally, we implemented an SDN supervisory controller on the network layer and a global SDN supervisory controller to improve operational counts for security. Furthermore, a security layer with a local and a global security controller was implemented. To test the proposed framework's compatibility, we constructed a network using Mininet, consistingof virtual hosts, switches, controllers, and links. In order to connect the various domains and the control centre, the network usesa wide area network. The switch takes an average of 120 milliseconds, with a packet loss rate of 1.89 percent on average, according to simulation and experiment results. A more efficient security architecture has been put forth, and it issuperior to the one currently in place.
