Claim:
1. A computer-implemented method in an SDN (Software-Defined Networking) controller of a communication network for optimizing multimedia downloads at a remote data plane responsive to user playback behavior, the method comprising the steps of: detecting a progressive download of a multimedia file in progress to a station through a first access point; examining packets of the multimedia file to determine a file name for the multimedia file; determining that users discontinue playback of the multimedia file of the determined file name beyond a certain duration; in response to surpassing the certain duration, generating one or more OpenFlow rules to implement a target download rate at a data plane of the first access point, wherein the data plane is remote to the SDN controller, and wherein the target download rate is reduced to reflect the tendency of uses to discontinue playback; implementing the one or more OpenFlow rules at the data plane of the first access point to meet the target download rate.
