Patent ID: 8000242

Claim:
A method of reducing packet loss for a packet data service in a data transport network, the method comprising: measuring, at a plurality of first controllers implemented in a receiver at one end of a network link between a base station and a radio network controller in the data transport network, a plurality of packet loss rates over a selected window, each packet loss rate being measured for one of a plurality of concurrent parallel flows of data traffic packets associated with said packet data service, the plurality of concurrent parallel flows travelling over the network link to the receiver; detecting congestion in at least one of the concurrent parallel flows of data traffic packets based on the measured packet loss rates; and independently triggering, using the plurality of first controllers, a reduction in a flow rate of each concurrent parallel flow of data traffic packets for which congestion is detected, wherein a plurality of second controllers implemented in a transmitter of said transport network is used for reducing an overall packet loss across best-effort packets in said one or more concurrent parallel flows of data traffic packets, each second controller being associated with one concurrent parallel flow.
