Processing system for multi-controller deployment in SDN network

Abstract

The invention discloses a processing system for multi-controller deployment in an SDN network, which is applied to the SDN network including an Openflow switch, a controller expansion pool and a controller. According to the system, a processing module is taken as the core, and a monitoring unit in the processing module is used to determine that the network state includes different network states such as static, dynamic or expanded states; a static deployment unit, a network flow prediction unit and an emergency system management unit in the processing module are used to determine a network design scheme and the optimal number of nodes of the controller in the corresponding network states; a controller expansion unit in the processing module is used to activate or hibernate the controller in the controller expansion pool; and an optimization adjustment unit in the processing module is used to realize network adjustment according to the network design scheme. According to the scheme of the invention, a multi-controller deployment strategy can be changed in real time according to the network states, the network load balancing can be ensured, and the smooth operation of networks can berealized.

Description

Technical field [0001] The invention relates to a processing system for multi-controller deployment in an SDN network, in particular to a multi-controller optimized deployment based on multiple optimization targets for different network states. Background technique [0002] With the rapid development of the Internet, traditional networks have many problems, such as high configuration complexity, complicated network protocols, and difficulty in expanding equipment. These problems indicate that the network architecture needs innovation. Software Defined Networking (SDN) as a new network technology and architecture, its core value has been widely recognized by the industry. It reduces configuration errors, liberates manual operations, and is easy to uniform and rapid deployment. More and more researchers are paying attention to the future development of SDN technology. [0003] The core idea of ​​SDN is to separate the control function from the switch to form a unified and centraliz...

AI Technical Summary

Problems solved by technology

Existing static deployment strategies often consider one or two influencing factors, but fail to pay attention to the relationship between the number of controllers and many influencing factors; existing dynamic deployment strategies often consider how to adjust when a problem occurs in the network, and fail to notice Predict network changes in advance and adjust the control domain; at the same time, there is a lack of consideration of controller load changes when the network scale expands
