Abstract
Techniques for distributing data packets over a network link bundle include storing an output data packet in a data flow queue based on a flow identification associated with the output data packet. The flow identification indicates a set of one or more data packets, including the output data packet, which are to be sent in the same sequence as received. State data is also received. The state data indicates a physical status of a first port of multiple active egress ports that are connected to a corresponding bundle of communication links with one particular network device. A particular data flow queue is determined based at least in part on the state data. A next data packet is directed from the particular data flow queue to a second port of the active egress ports. These techniques allow a more efficient use of a network link bundle.
