    摘要: A method for selecting a hash function, a method for storing and searching a routing table and devices thereof are provided. The method for selecting a hash function includes: hashing data to be hashed by using a current alternative hash function; decoding a hash result; accumulating decoded results until no carry occurs during the accumulation; and selecting a current alternative hash function with no carry generated as a formal hash function. The method for storing a routing table includes: dividing the routing table into a next-level node pointer portion and a prefix portion for being stored; and selecting a hash function by using the above method for selecting a hash function. The method for searching a routing table includes: directly searching an IP address to be searched according to a directly stored length of a next-level node pointer portion for storing the routing table; and reading a prefix node according to a searched result. Thus, hash collision can be avoided, and memory resources occupied by the routing table can be effectively reduced.

    摘要: The present invention discloses a method and apparatus for longest prefix matching. The method includes (A) reading a current-level trie node (TNODE) in the trie, (B) determining whether an offset field of the TNODE indicates that a matched prefix exists in an upper level node and, if so, adding the offset field of the TNODE to a pointer that points to a leaf array in the upper level node, updating a current best match pointer with the computation result and executing block (C), otherwise, executing block (C), (C) determining whether the TNODE has a child node according to a child bitmap, when it is determined that a branch flag of the TNODE matches a corresponding bit of a search keyword, and (D) when it is determined that the TNODE has no child node, reading the internal bitmap of the TNODE, computing a longest matched prefix in the TNODE according to the internal bitmap and a pointer that points to a leaf array in the TNODE, updating the current best match pointer with the computation result, and computing an address of a leaf node (LNODE) associated with the current best match pointer.
