QoE based holistic traffic engineering in SDN enabled heterogeneous transport networks

Due to the variability of network topologies and services that can be deployed in the transport network, traffic engineering decisions within a software defined networking (SDN) controller need to be influenced by the current network topology, available resources, and end user experience. In this work a holistically approached traffic engineering quality of experience (QoE) feedback application is demonstrated, built on top of a real SDN transport network for heterogeneous optical, 5G and satellite services. This QoE feedback application is split across the SDN controller and client machines, and is shown to provide improvements to end user experience in high load scenarios tested in this paper for multicast SatIP video applications. The proposed solution can also combine unicast, internet streamed and mobile applications.
