Software-Defined Networking (SDN) is a different approach to manage a network by software. It could use well-defined software expressions and predicates to regulate network behavior. Current SDN controllers, such as Floodlight, offer a framework to develop, test and run applications that control the network operation, including the firewall function. However, they are not able to validate firewall policies, detect conflicts; neither avoids contradictory configurations on network devices. Some… CONTINUE READING
