"Weighted load balancing using scaled parallel hashing" was invented by Abdul Kabbani (San Francisco) and Amin Vahdat (Los Altos, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method for weighted data traffic routing can include receiving a data packet at data switch, where the data switch includes a plurality of egress ports. The method can also include, for each of the egress ports, generating an independent hash value based on one or more fields of the data packet and generating a weighted hash value by scaling the hash value using a scaling factor. The scaling ...
