In accordance with one embodiment, a source leaf device receives a packet. The source leaf device identifies a flowlet associated with the packet and a destination leaf device to which the packet is to be transmitted. The source leaf device may determine whether the flowlet is a new flowlet. The source leaf device may select an uplink of the source leaf device via which to transmit the flowlet to the destination leaf device according to whether the flowlet is a new flowlet. The source leaf device may then transmit the packet to the destination leaf device via the uplink.

Apparatus, systems and methods may be used to monitor data flows and to select and track particularly large data flows. A method of tracking data flows and identifying large-data ('elephant') flows comprises extracting fields from a packet of data to construct a flow key, computing a hash value on the flow key to provide a hashed flow signature, entering and/or comparing the hashed flow signature with entries in a flow hash table. Each hash table entry includes a byte count for a respective flow. When the byte count for a flow exceeds a threshold value, the flow is added to a large-data flow ('elephant') table and the flow is then tracked in the large-data flow table.
