Abstract: This application discloses a flow entry generating method and apparatus. The method includes: receiving a service path establishment request, where the service path establishment request includes a constraint, a source device, and a target device; finding, in a data transmission network according to a cross-layer information model, a service path that meets the constraint and is from the source device to the target device, where the cross-layer information model is a model that describes, at a same layer, an overall topology relationship between an IP layer and an optical layer; and generating a respective corresponding flow entry for each forwarding device in the service path, and sending the flow entry to a corresponding forwarding device. This application can greatly reduce time complexity of computing the service path, and improve efficiency of computing the service path, thereby improving efficiency of generating a flow entry.

Abstract: The application provides a scheduling method, apparatus and system. A controller receives scheduling request information sent by a content source. The scheduling request information includes a constraint condition of non-real-time traffic transmission, and the constraint condition includes: information about a first address and information about a second address. A first forwarding path and a sending time for sending the traffic are determined according to the information about the first address, the information about the second address, and statistical information about network traffic. The controller sends a first message that includes a sending rate to the content source at the sending time, and the traffic is sent through the first forwarding path.
