基于SDN的高校网络安全数据传输管理研究

Research on the Management of Secure Data Transmission in College Network Based on SDN

随着网络应用、需求的多样化,传统的校园网络的三层结构已经无法适用于现代的环境中,利用SDN网络的控制和数据转发分离结构能够有效实现高校网络的集中管理和控制,有利于高校网络的扩展和控制,以满足多样化的业务需求。但SDN网络在安全方面存在的不足,针对这一问题,提出了SDN安全扩展网络-SDNs网络,通过控制器的设计、数据平面设计、数据包头设计,实现了SDNs网络,实验表明SDNs网络的吞吐量和延迟在应用网络攻击时不会产生剧烈震动。

With the diversification of network applications and demands, the traditional three-tier structure of campus network can no longer be applied to the modern environment. The centralized management and control of university network can be effectively realized by using the control and data forwarding separation structure of SDN network, which is conducive to the expansion and control of university network to meet the diversified business needs. However, SDN network has some shortcomings in security. To solve this problem, the SDN security extension network-SDNs network is proposed. SDNs network is realized through controller design, data plane design and data head design. Experiments show that the throughput and delay of SDNs network will not cause severe vibration when network attacks are applied.
