A network device includes a communication interface. A processing system is coupled to the communication interface. A memory system is coupled to the processing system and includes instructions that, when executed by the processing system, cause the processing system to receive first traffic though the communication interface and forward the first traffic downstream though the communication interface using a first path. The memory system also includes instructions that, when executed by the processing system, cause the processing system receive a congestion notification from a downstream network device through the communication interface and determine whether the congestion notification is associated with the first traffic. In response to the first traffic being associated with the congestion notification, the processor determines whether a second path exists for forwarding subsequent traffic that is associated with the congestion notification downstream though the communication interface.
