Software Defined Networking (SDN) provides considerable simplification of design and deployment of various network applications for large networks. Each application has its own view of network policy and sends its policy to a network hypervisor in which a composed policy is generated from the application policies and deployed into the data plane. A significant challenge for the hypervisor is to detect and resolve both intra and inter policy anomalies during the policy composition. However, current SDN compilers do not consider the policy anomalies well and generate large number of unnecessary rules for the data plane. This leads to a considerable inefficiency in both policy composition and policy deployment. In this paper, we propose a novel framework for policy composition in a SDN hypervisor which takes into account both inter and intra policy anomalies. Moreover, we augment the framework with an efficient insertion transformation mechanism which allows the applications to issue rule insertion and priority change updates. Our evaluation shows that our method is several orders of magnitude more efficient than the state of the art in both policy composition and compiling the rule insertion updates. |
