Methods and systems for dynamic congestion management in communications networks that advantageously provides a satisfactory Quality of Experience (QoE) of real time communication for network users. Congestion management is achieved wherein an ingress interface is monitored by a data processing system and when utilization of that interface exceeds a first activation level a message is sent to a second data processing system wherein that second data processing system is a source for at least some of data packets traversing the ingress interface, wherein the first message indicates that traffic shaping is to occur in accordance with the first activation level and only if the utilization falls below a deactivation level, transmitting a second message to the second data processing system wherein the second message indicates that traffic shaping is to stop.
