A method for performing flow based address hash transformation in a network device to generate hash pointers. The method includes the steps of receiving a pair of addresses (source address input and destination address input) corresponding to one direction of a data flow. The destination address input is modified by using a rotation operation. Respective hash operations are subsequently performed on the source address input and modified destination address input. The rotation operation performed on the destination address input prevents aliasing between the hash results for the forward direction of a data flow and the reverse direction, thereby preventing hash pointer collisions.
