As one of the most popular south-bound protocol of software-definednetworking(SDN), OpenFlow decouples the network control from forwardingdevices. It offers flexible and scalable functionality for networks. Theseadvantages may cause performance issues since there are performance penaltiesin terms of packet processing speed. It is important to understand theperformance of OpenFlow switches and controllers for its deployments. In thispaper we model the packet processing time of OpenFlow switches and controllers.We mainly analyze how the probability of packet-in messages impacts theperformance of switches and controllers. Our results show that there is aperformance penalty in OpenFlow networks. However, the penalty is not much whenprobability of packet-in messages is low. This model can be used for a networkdesigner to approximate the performance of her deployments.
