摘要： This application provides a method, a device, and a system for determining a required bandwidth for a data stream. The method includes: obtaining, by a control device, a service requirement latency of transmitting a data stream from a first network device to a second network device; obtaining, by the control device, a network device transmission latency on a forwarding path and a link transmission latency on the forwarding path; and determining, by the control device based on the service requirement latency of the data stream and the network device transmission latency and the link transmission latency on the path for forwarding the data stream, a required bandwidth for transmitting the data stream. The foregoing method may be used to guide network resource deployment for a data stream that has a latency requirement, to ensure a low latency for data stream transmission.

摘要： Embodiments of this application disclose a service traffic adjustment method and apparatus, to reduce a network resource waste, and improve network usage efficiency. The method includes: A first controller obtains a first limit value of a traffic parameter and a second limit value of the traffic parameter, where the traffic parameter is a parameter of traffic corresponding to a service flow. The first controller obtains a target value of the traffic parameter based on the first limit value of the traffic parameter, the second limit value of the traffic parameter, and configuration information of a forwarding device through which the service flow passes. The target value of the traffic parameter meets a delay requirement of the service flow, the target value falls within a range determined based on the first limit value of the traffic parameter and the second limit value of the traffic parameter, and the first limit value is not equal to the second limit value. The first controller sends the target value of the traffic parameter, where the target value is used to adjust the traffic of the service flow sent by a transmit end.

摘要： This application provides a method, device, and system for determining a bandwidth for service flow transmission. The method includes: A first device obtains a first traffic sampling set of a service flow, where the first traffic sampling set includes one or more pieces of traffic sampling information. The first device obtains a service level parameter corresponding to the service flow and a reliability probability of meeting the service level parameter. The first device determines, based on the first traffic sampling set, the service level parameter, and the reliability probability, a bandwidth for transmitting the service flow. Using the method can improve reliability of service flow transmission.

摘要： This application discloses a service level configuration method and apparatus, and belongs to the field of communications network technologies. According to the 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.

摘要： A network configuration method and device are disclosed. The method includes: determining an end-to-end latency upper bound of data traffic between two end nodes; determining an end-to-end latency constraint of the data traffic between the two end nodes; determining, based on the end-to-end latency upper bound and the end-to-end latency constraint, for a first network shaper, at least one configuration parameter that satisfies the end-to-end latency constraint; and configuring the first network shaper for the data traffic based on the at least one configuration parameter, so that the traffic after being shaped by the shaper satisfies the network latency constraint. Therefore, network congestion is reduced, and transmission quality is improved. A per-hop buffer upper bound in a traffic forwarding process is determined based on network calculus, and a buffer is configured on a per-hop forwarding node based on the buffer upper bound, to appropriately reserve a network resource and satisfy a traffic forwarding requirement.
