  • Patent number: 11570105
    Abstract: The present disclosure involves systems and methods for managing a trie routing table for a networking device of a communication or computer network. In one implementation, the networking device may utilize a dynamic algorithm for associating hashing functions with pivot tiles of the routing table to improve hash utilization and avoid hash collisions. Further, route prefixes may be relocated from pivot tiles in an attempt to free the tiles for reallocation to other prefix base width or may be relocated to other possible pivot tiles or to a general storage space when a hash collision is detected. This provides for even distribution of pivots within tiles which have base widths in range of a pivot route. The above implementations may occur together or separately to improve the operation of the networking device and provide faster route lookup.
