Research And Design Of Campus Network Based On SDN Architecture

At present,the campus network of colleges and universities is in a stage of technological innovation and overflight.At the same time,the change of users' demand for network use also brings great challenges to the network operation and maintenance and builders.Adopting SDN network technology to carry out innovative design and construction of campus network in Colleges and universities is a work that has a positive impact on campus network.It can solve many contradictions and problems that cannot be solved by traditional campus network.It will inevitably improve the scalability,mobility,manageability and rationality of the network,and provide multi business support.This paper focuses on the design,transformation and construction of campus network through SDN network technology.This topic comes from the actual network construction and transformation project in Colleges and universities.In the preparatory work of the early stage,the current situation of the campus network in Colleges and universities is investigated and analyzed comprehensively.Combined with the characteristics of SDN network technology,the construction and transformation scheme of the campus network is given.Three aspects of work are mainly carried out for the campus network and the data center network in Colleges and universities.(1)Based on SDN technology,the network topology of campus network is designed,and the design focuses on three aspects: Overlay network architecture,user roaming and network automation deployment.(2)Based on SDN technology,the deployment scheme of campus network data center network is planned in detail,and the application practice of Overlay and Underlay technology is carried out according to the actual application scenarios.(3)The overall operation and maintenance management of campus network under SDN framework is planned in detail.Through these aspects of the construction and transformation,to solve the campus network for a long time the pain.The centralized management and control of multiple services makes the work of network managers more effectively run through the core level of network management.Meanwhile,for the adjustment of old services,the speed of new business distribution has been greatly improved.Multi area interconnection and data transmission are effectively guaranteed,which has good practical value.
