Design and Implementation of SDN-based Flow Control Middleware

The design of middleware plays a very important role in traditional networks and their devices, but there is a distributed control problem in only configurable and non-programmable networks. The TCP network model cannot solve the design problem of middleware in traditional networks and their devices, and the design is unreasonable. Therefore, this paper proposes an SDN flow control to analyze the design of various interface protocol middleware. Firstly, SDN software-defined network is used to design middleware, and indicators are divided according to the design requirements of middleware to reduce interference factors in middleware design. Then, SDN software-defined network builds the design of middleware with multiple interface protocols, forms the middleware design scheme, and comprehensively analyzes the middleware design results. MATLAB simulation shows that under certain design standards, SDN flow control is better than TCP network mode for the design accuracy and design time of middleware for constructing multiple interface protocols.
