采用控制、转发分离架构的软件定义网络(SDN)为网络的可编程性与开放性提供极大便利,但也给网络的安全性带来诸多挑战。提出一种虚拟安全网络(Virtualized Security Networks)与数据层中间盒扩展相结合的SDN安全架构,给出该架构的实现要点,并以实验验证其架构实现。测试表明该架构较其他方式具有更好的性能与可扩展性,同时其更有利于传统网络环境下的安全保障机制面向SDN网络架构的过渡迁徙。
採用控製、轉髮分離架構的軟件定義網絡(SDN)為網絡的可編程性與開放性提供極大便利,但也給網絡的安全性帶來諸多挑戰。提齣一種虛擬安全網絡(Virtualized Security Networks)與數據層中間盒擴展相結閤的SDN安全架構,給齣該架構的實現要點,併以實驗驗證其架構實現。測試錶明該架構較其他方式具有更好的性能與可擴展性,同時其更有利于傳統網絡環境下的安全保障機製麵嚮SDN網絡架構的過渡遷徙。

Software Defined Networking is in its fast growth in the past years. Its software programmable architecture and openness brings many of new security challenges. Proposes a novel SDS security architecture based on Virtuallzed Security Networks. Discusses the critical fea-tures and use cases of VSN security model in detail, and also verificates its implementation by testing. The analysis shows that the VSN security architecture has better performance and scalabilities with compared with other security models.
