    摘要： A method to provide load distribution that selects one of a set equal cost paths for each flow that minimizes imbalance in the distribution of flows across the set of equal cost paths, the method including calculating the set of equal cost paths to each destination node, generating a set of next hop discriminators for the set of equal cost paths, each next hop discriminator in the set of next hop discriminators to uniquely identify one of the equal cost next hops, populating the load distribution table by storing, according to a distribution mechanism, in each load distribution table entry one of the next hop discriminators from the set of next hop discriminators, receiving a first PDU from a first flow and performing a lookup of one of the next hop discriminators in the load distribution table by using values at the bit locations of the first PDU directly as an index into a CAM.
