  • High-performance network processor
    Patent number: 6778534
    Abstract: A high-speed system for processing a packet and routing the packet to a packet destination port, the system comprising: (a) a memory block for storing tabulated entries, (b) a parsing subsystem containing at least one microcode machine for parsing the packet, thereby obtaining at least one search key, (c) a searching subsystem containing at least one microcode machine for searching for a match between said at least one search key and said tabulated entries, (d) a resolution subsystem containing at least one microcode machine for resolving the packet destination port, and (e) a modification subsystem containing at least one microcode machine for making requisite modifications to the packet; wherein at least one of said microcode machines is a customized microcode machine.

  • Deterministic search algorithm
    Patent number: 6625612
    Abstract: A method for storing and retrieving a key using a hash table, the method comprising the steps of: (a) hashing the key using a first hash function, thereby transforming the key into a table address in the hash table; (b) hashing the key using a second hash function, distinct from the first hash function, thereby transforming the key into a key signature; and (c) entering the key signature in a signature page located at the table address.

  • Wildcards in radix- search tree structures
    Patent number: 6594655
    Abstract: A system for storing and retrieving data using a radix-search tree having a plurality of sub-trees containing nodes and leaves, the system including: (a) a data storage module designed and configured for storing the plurality of sub-trees, wherein at least one of the leaves contains at least one entry having at least one wildcard in a primary position, and (b) a processor that is operative to perform operations including: (i) building the radix-search tree in the data storage module, and (ii) retrieving data from the radix-search tree in the data storage module.
