Abstract
A method and apparatus for controlling data transmission includes: obtaining an amount of data, the data requested by a requesting server, an instructed deadline, and candidate source servers storing the requested data; obtaining, based on the amount of data, a minimum bandwidth required for transmitting the requested data before the deadline as a required bandwidth corresponding to the requested data; and selecting one of the candidate source servers as a source server for transmitting the requested data, based on the required bandwidth, bandwidth resources of the candidate source servers and the requesting server, and remaining bandwidth of links between the candidate source servers and the requesting server. This implementation implements the selection of the most appropriate source server from the holistic perspective, ensures that data transmission can be completed before the deadline, and effectively utilize the link bandwidth.
