Weighted cost multipath packet processing

A network switch device comprising:

• a plurality of ports corresponding to a number of paths;
• a memory storing 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;
• one or more processing components configured to:
• receive a network packet for routing through one of the number of paths;
• select, via a first function applied to the network packet, a record from the plurality of records;
• determine, via a second function applied to the network packet, a routing value within a predefined range of values;
• choose, 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;
• and
• route the network packet through the one of the number of paths based on the chosen routing index.

A non-transitory storage medium comprising instructions that, when read by one or more processors, cause a method comprising:

• receiving a network packet for routing through one of a number of paths of a network switch device;
• 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;
• determining, via a second function applied to the network packet, a routing value within a predefined range of values;
• 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;
• and
• routing the network packet through the one of the number of paths of the network switch device based on the chosen routing index.
