SDN (Software Defined Network) controller architecture based on MDC (Module Data Center) management system

Abstract

The invention discloses SDN (Software Defined Network) controller architecture based on an MDC (Module Data Center) management system and belongs to the technical field of data centers. The SDN controller architecture based on the MDC management system comprises a logical layering assembly, an updating check module, a security isolation domain, a shared network information base, an invasion tolerance control module, a secure sandbox module, a rule policy set module, an application audit authentication module, an authority management module and a conflict detection module. The updating check module is set in a southbound protocol service unit of a control layer. The security isolation domain and the shared network information base are set in a resource pool of the control layer. The securesandbox module, the rule policy set module, the application audit authentication module, the authority management module and the conflict detection module are set in an application management unit ofthe control layer. According to the SDN controller architecture based on the MDC management system provided by the invention, the robustness of an SDN can be improved, a business system is guarantee to operate stably and reliably, and the SDN controller architecture has good popularization and application value.

Description

technical field [0001] The invention relates to the technical field of data centers, and specifically provides an SDN controller architecture based on an MDC management system. Background technique [0002] MDC (Module Data Center) is a new generation of data center deployment form of cloud computing. In order to cope with the development trend of servers such as cloud computing, virtualization, centralization, and high density, it adopts a modular design concept to maximize Reduce the coupling of infrastructure to the computer room environment. It integrates subsystems such as power supply and distribution, refrigeration, cabinets, airflow containment, integrated wiring, and dynamic environment monitoring to improve the overall operational efficiency of the data center and achieve rapid deployment, elastic expansion, and green energy saving. [0003] SDN (Software Defined Network) is a network design concept and a framework. Its core idea is to separate the control plane f...

Problems solved by technology

While the SDN network architecture utilizes its programmability, centralized control, and fine-grained management to obtain richer functions, it also faces many security challenges, such as malicious data flow, switch flow table tampering, application software vulnerabilities, and data management confidentiality and availability. Attacks common in traditional networks, such as threats, are still possible in SDN
