Abstract

The invention relates to an SDN based campus network structure. The SDN based campus network structure comprises internet service providers and routers which are connected in sequence; the routers are also connected with an SDN switch; the SDN switch is respectively connected with an SDN controller and an SDN device; the SDN controller performs centralized control on a bottom SDN device through the SDN switch; after the SDN device is connected at the edge of a network, partial services of the campus network are firstly transferred to an SDN service system, then all the edge services are gradually transferred to the SDN service system and the SDN is deployed to a core service after services are perfected; and the SDN switch is responsible for data exchange of the whole network and data forwarding between each system and different services. According to the SDN based campus network structure, the network automatic management and control capability is improved greatly.

Description

technical field [0001] The invention relates to the field of network technology, in particular to an SDN-based campus network network structure. Background technique [0002] The campus network is a computer network provided to school teachers and students for daily education, scientific research, and resource sharing. The increasing development of information technology and the continuous growth of the campus network have highlighted the necessity and importance of the campus network for the construction of colleges and universities. It is an indispensable part of the modern campus construction. Most colleges and universities have established their own campus networks, and according to The existing network technology is transformed and upgraded. Promote the development of information-based campuses and intelligent campuses. How to use the campus network reasonably and efficiently and ensure the safety and stability of the campus network is an important problem. In the ex...
