Abstract
A method is provided of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers, the bearers each carrying data packets that relate to different ones of a plurality of services. In the method, for each bearer independently of the other bearers, bandwidth profiling is applied to the data packets of the bearer to identify and mark the data packets of each of the bearers that are conformant with a determined maximum information rate for the bearer. The data packets are forwarded for transport through the transport network. If there is insufficient bandwidth available in the transport network to transport all data packets, data packets not identified by the profiling as being conformant are discarded, so as not to be transported through the transport network. The data packets of the bearer transported through the transport network are monitored to determine whether there has been any loss of data packets that should have been transported through the transport network, indicating congestion in the transport network. The maximum information rate of the bearer is adjusted based on the monitoring.
