Abstract
The disclosed systems and methods provide weighted cost multipath for packet processing devices. A method includes receiving a network packet for routing through one of a number of paths of a network switch device. The method also includes selecting, via a first function applied to the network packet, a record from a plurality of records corresponding to the number of paths, wherein each of the plurality of records includes a threshold, a first routing index, and a second routing index. The method also includes determining, via a second function applied to the network packet, a routing value within a predefined range of values. The method also includes choosing, from the selected record, the first routing index or the second routing index based on whether the routing value meets the threshold of the selected record. The method also includes routing the network packet based on the chosen routing index.
