Disclosed in the present invention are a method and apparatus for selecting a transmission resource for streaming data. The method comprises: selecting at least one transmission node for current streaming data from a current transmission node cluster; according to a current load of the pre-obtained selected transmission node, pre-estimating an actual load of the transmission node for coping with a scheduling node cluster; and correcting the selected transmission node according to the actual load. According to the technical solution of the present invention, a transmission node is selected for transmission of streaming data by means of a scheduling node cluster; the problem of processing performance bottleneck in selection of the transmission node by a single scheduling node for transmission of streaming data is resolved; the transmission node selection efficiency is improved; and the problem of excessively high load of a single transmission node due to simultaneous selection of transmission nodes by scheduling nodes in the scheduling node cluster for transmission of the streaming data is resolved.
