Advances of configuring Quality of Service (QoS) in Software Defined Networks (SDN) by using meter table

New technologies introduce more services which will call for significant advances and changes in IP networks. Networks will have to go in the direction of network programmability, virtualization and cloud-based services. In this paper, Quality of Service (QoS) is configured in two different environments: (i) in traditional IP network using QoS policy-maps and (ii) in Software Defined Network. Two scenarios are compared in order to emphasize the benefits of using SDN technology when providing QoS provisioning mechanisms.
