- Abstract
- The QoS requirements of various services have created a big challenge in the virtualization environments for cloud networking that cannot support the fine-grained network QoS management. As an emerging technology for satisfying these requirements, the Software Defined Networking (SDN) has the potential to enable dynamic configuration and control for the enhanced network management. This paper presents the design of an intelligent controller based on network policy in the environments of virtual networks that hide the details of an underlying physical topology. The proposed controller performs the mechanism for policy-driven intelligent control to provide differentiated virtual network services based on the content of an OpenFlow packet header and mapping relationships between physical infrastructure and virtual overlay network. With this approach, the intelligent controller enables the deployment of various services on multiple virtual networks as well as the flexible management for achieving a better QoS. Furthermore, it can distribute the traffic with different QoS requirements on available paths under the constraints of available resources by adopting the structure for enforcing the QoS policy of flows.
