Patent number: 9571384Abstract: A QoS management scheme for SDN. Network resource availability of routers and switches are maintained in a central resource database of a SDN controller. The SDN controller performs resource reservation, admission control and route calculation. When a flow is admitted or completed, the resource database is updated accordingly.
