  • Patent number: 10897422
    Abstract: The technology disclosed herein enables network traffic routing using a hybrid routing table. In a particular embodiment, a method provides adding a first portion of a network prefix to one or more tiers of one or more tries in the hybrid routing table. Upon reaching a lowest node of the one or more tries when adding the first portion of the network prefix, the method provides adding key information to the lowest node. The key information and at least a second portion of the network prefix comprise a key to locate a value in a hash table of the hybrid routing table. The value indicates routing information for the network prefix. Additionally, the method provides routing packets using the hybrid routing table.
