摘要

In this paper, we design an architecture to implement a QoS system based on OpenFlow. The system can filter malicious packets that have no permission to gain quality of service, and can guarantee scheduling the fastest path for QoS packets in working network. By predicting and estimating current network flows, we implement to assign optimal path for QoS flow without affecting the rest of the normal packet transmission. We can also implement to transferring the packet even in congested networks by simply flushing all flow-tables in the switches and rescheduling the path for different packets. All the provisioning of our system can be flexible and real-time updated. We implement the system based on POX controller, verify and evaluate our design goals.
