The Software Defined Networking (SDN) is a new network innovation architecture, and the open OpenFlow technology is one of the most efficient technique for realizing the SDN architecture. In order to further study the characteristics of SDN architecture and provide the definable network platform for application innovation, the simulation of SDN architecture is implemented by using the Mininet simulation software based on OpenFlow technology. This paper summarizes the characteristics of typical SDN architecture, analyzes the simulation principles and methods based on OpenFlow technology, and verifies the functions and basic workflows of SDN architecture based on Mininet simulation software construction. The proposed simulation methods and platform provide the effective technical support for the research on SDN architecture.
