基于SDN的第三方业务请求审计系统

Software-Defined Network opens network modification capabilities with standard north-bound APIs. The forwarding modification requests received by these standard north-bound APIs in the controller may result in illegal network resources access and routing loops which can cause packet loss and unacceptable quality of service. Thus, reliable audit is required to mitigate the threat of business requests. In this paper, we propose a third-party business requests auditing system which addresses the key challenges: how to ensure the safe access to network resource management andhow to ensure the QoS of traffic. Testbed is built to simulate our proposed system, the evaluation shows that the secure access assurance strategy, is able to provide a good protection, and the QoS module can calculate and address suitable route and queue for demanded user data traffic.
