Abstract: This application discloses a service level configuration methods and apparatuses, and belongs to the field of communications network technologies. According to an example method, a target service level used by a first forwarding node to forward a data flow is directly determined based on a transmission parameter of the data flow and service level information of the first forwarding node, and service level configuration is performed on the first forwarding node. Because a transmission parameter of the target service level of the first forwarding node and the transmission parameter of the data flow meet a first target condition, if the first target condition is a delay requirement required by a special service and the first forwarding node transmits the data flow by using the target service level, transmission of the data flow may meet the delay requirement required by the special service.

Abstract: A control device for a software programmable network including one or more nodes and supporting traffic of guaranteed quality of service, QoS, and best-effort, BE, traffic with a predetermined resource distribution between guaranteed QoS and BE service classes, comprises: a processing circuitry configured to determine a new resource distribution between guaranteed QoS and BE service classes different from the predetermined resource distribution according to a demand for QoS service, to calculate, for each node, a new configuration indicating the new resource distribution, and to calculate, for each entry node to the network among the one or more nodes, a label distribution sequence indicating one or more label distributions with associated activation timing information so as to reduce jitter or packet loss; and a transceiver configured to transmit the new configurations to respective nodes, and to transmit the label distribution sequences to respective entry nodes.
