In a packet-based communications network (100), a virtual connection is established between a source node (102a) and a destination node (102b), which may traverse one or more intermediate nodes (105). During the flow of packets along the virtual connection in a forward direction, from the source node (102a) to the destination node (102b), each node measures the utilization of critical resources (CUF), and this utilization information is inserted into return packets flowing in the backward (return) direction, from the destination node (102b) to the source node (102b). CUF is indicative of the maximum utilization of any resource in the virtual connection forward path. If the network utilization information indicates that the resources of a virtual connection are under-utilized, the submission rate (SIR) of packets onto the virtual connection is increased. However, if the network utilization information indicates that the resources of the virtual connection are over- utilized, the submission rate of packets onto the network at the source node is reduced.
