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.
