Data transmission control methods and devices

摘要

A method of controlling a receiver of a data unit communication from a data source is described, said receiver being associated with a first terminal of a data unit communication network providing said first terminal with a transport service characterized by a set of values associated with respective service quality parameters, said service quality parameters comprising a Guaranteed Bit Rate (GBR), said data source being associated with a second terminal. The method comprises determining, by the receiver, whether a received data unit contains an Explicit Congestion Notification (ECN). If said ECN is detected, the method further comprises sending, from the receiver, to said data source a message for adjusting a data transmission rate of said data source, said message indicating as an upper bound for said data transmission rate a value corresponding to a value associated with the GBR for said first transport service.

1. A method for controlling a receiver of a data unit communication from a data source, said receiver being associated with a first terminal of a data unit communication network providing said first terminal with a transport service characterized by a set of values associated with respective service quality parameters, said service quality parameters comprising a Guaranteed Bit Rate (GBR), said data source being associated with a second terminal, said method comprising:
determining, by the receiver, whether a received data unit contains an Explicit Congestion Notification (ECN), if said ECN is detected, sending, from the receiver, to said data source a message for adjusting a data transmission rate of said data source, said message indicating as an upper bound for said data transmission rate a value corresponding to a value associated with the GBR for said first transport service.
