Abstract
A network system (10). The system comprises a plurality of nodes (PE, CE). Each node in the plurality of nodes is coupled to communicate with at least one other node in the plurality of nodes. Further, each node in the plurality of nodes is coupled to communicate to another node via a respective primary path and via a respective backup path. Still further, each node in the plurality of nodes is operable to perform the steps of, when receiving network traffic as a receiving node, detecting delay (110, 120; 130, 140; 160, 170) in traffic received from a transmitting node, and, in response to detecting delay, communicating a signal to the transmitting node. In response to the signal, the transmitting node is operable to dynamically adjust (150; 190) a distribution of traffic through a respective primary path and a respective backup path from the transmitting node to the receiving node.
