  • Patent number: 6956854
    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.

  • Patent number: 6553000
    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 lookup table also includes network address that differ in length. Fictitious network addresses may also be added to the lookup table to expedite searches in the lookup table. The fictitious network addresses are used in conjunction with a comparison field stored in the lookup table. The comparison field allows network addresses and collapsed network addresses (which represent groups of network addresses) to be stored within the same table. The collapsed network addresses allows for a reduction of overall lookup table size, thereby increasing the speed while reducing the cost of the switching device.
