  • Publication number: 20030058864
    Abstract: A switching device for forwarding network traffic to a desired destination on a network, such as a telephone or computer network. The switching device includes multiple ports and uses a lookup table to determine which port to forward network traffic over. The lookup table includes network addresses that are maintained in ascending or descending order. The switching device includes multiple binary search engines coupled in series including one or more precursor binary search engines and a final stage binary search engine. Together, the binary search engines perform an N iteration binary search. Additionally, a single search engine can perform multiple concurrent searches so that source and destination addresses can be obtained simultaneously and without wasted memory cycles.

  • Publication number: 20020051450
    Abstract: A switching device for forwarding network traffic to a desired destination on a network, such as a telephone or computer network. The switching device includes multiple ports and uses a lookup table containing lookup keys to determine which port to forward network traffic over. The lookup tables are populated based on use. Consequently, the lookup tables on different ports contain different addresses. By storing only addresses that a port uses, each port's lookup table is unique to that port's characteristics. Additionally, aging techniques are used on both source and destination addresses in the lookup table so that stale entries are removed and memory is conserved.
