Abstract:
As the diversity of emerging services has increased, the flow of traffic with various characteristics has occurred over the Internet. These various traffics require different treatments from carrier network in order to meet the Quality of Experience (QoE) requirements for end users. As the emerging technology 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 a virtualization controller based on network policy in SDN environments. The proposed controller configures virtual networks in a flexible way for the deployment of various services by using virtual routers as the enabler of QoS policy enforcement. It can also perform dynamically the QoS control of flows, by using a network virtualization approach as a structure for enforcing the QoS and isolation policies of flows. With this approach, it enables various services to be deployed on multiple virtual networks and can achieve a better QoS.
