WEIGHTED LOAD BALANCING IN A MULTISTAGE NETWORK

A method for weighted data traffic routing can include generating an integer hash value based on a header of a data packet and encoding the integer hash value to generate a search key for a content addressable memory included in the data switch. The method can also include performing a lookup in the content addressable memory to match the search key with one of a plurality of prefixes stored in the content addressable memory, the plurality of prefixes including an encoded set of routing weights associated with a plurality of egress ports of the data switch. The method can further include forwarding the data packet on an egress port of the plurality of egress ports associated with the one of the plurality of prefixes in the content addressable memory.
