A SDN-Controlled ECMP QoS Solution for Data Networks
Abstract:
This paper presents a generic solution to guarantee the QoS of data network based on SDN control. This mechanism, called first detection and then ECMP switching (DES) has two points. The first one is sending specific control message periodical to detect out of order status of data flow. The second is switching the routing paths in variable periods according to the flows out of order proportion and QoS level. The mathematical analysis and simulation results both show DES good performance on guaranteeing the networks quality of services. And DES can be widely used in the SDN controlled data networks.
