Abstract
Provided are a method and device for implementing QoS in an OpenFlow network. The method includes that: for a packet entering an OpenFlow switch, when a flow table is successfully matched, an instruction which is used for calling a scheduler and adding the packet into a specified queue in the scheduler is executed; and under the triggering of the instruction, queue scheduling is managed by using the scheduler. By using the technical means provided by the disclosure, the technical problem in related art that the OpenFlow switch cannot implement Hierarchical QoS (HQoS) is solved, so that the OpenFlow switch may implement both single-layer QoS and HQoS.
