  • Method and apparatus for constructing and searching IP address
    Patent number: 7085235
    Abstract: The present invention discloses an IP address construction and lookup method and apparatus used in routers, which uses a compress technology to reduce memory size occupied by a segment array and a plurality of next hop arrays used in an indirect lookup table method, and also reduce the number of memory accesses from 1 to 4 times. Besides, only one memory access is required if a pipeline scheme is in use. In addition, when the routing table is updating, it is unnecessary to rebuild the forwarding table and capable of finishing newer actions.
