摘要：There is described a method for controlling bandwidth between a client and a content server in a data network. The method is implemented by an intermediate network entity that is between the client and the content server in the data network. A dataflow between the content server and the client is monitored and based on the monitoring, the dataflow is categorized as being an Adaptive Bit Rate (ABR) streaming dataflow that comprises segments of media data of a particular quality variant of a plurality of quality variants potentially available at the content server. A different quality variant of the plurality of quality variants is selected as a target quality variant and a bandwidth value is determined to apply to the dataflow to try to cause the client to request segments of media data of the target quality variant for the dataflow. The determined bandwidth value is applied to the dataflow.
