Abstract
Techniques are described for load balancing packet flows across parallel data paths. For example, a network device includes a plurality of parallel network interfaces and a control unit that applies each of a first set of hash functions to a packet and one of a second set of hash functions to the packet. Bins of each of the first set of hash functions are mapped to bits of a bit vector. Bins of each of the second set of hash functions are mapped to the plurality of parallel network interfaces. The control unit selects the one of the second set of hash functions to apply to the packet based on values of the bits of the bit vector. The control unit forwards the packet through the network interface that is identified by applying the selected one of the second set of hash functions to the packet.
