摘要
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. Dynamic queue mapping for QoS routing in SDN is also provided. For a traffic flow with a certain traffic description and delay requirement, the queue mapping protocol dynamically assigns the flow to different priority queues at different switches along its routing path. Compared with the static mapping of a flow to a specified priority queue, the disclosed mapping is more flexible and uses network resources more efficiently.
