    • 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.
    • 本发明公开了一种用于最长前缀匹配的方法和装置。 该方法包括:(A)读取该特技中的当前级别的特里节点(TNODE),(B)确定TNODE的偏移字段是否表示在上层节点中存在匹配的前缀,如果是, 将TNODE的字段指向指向上级节点中的叶阵列的指针,用计算结果和执行块(C)更新当前最佳匹配指针,否则执行块(C),(C)确定是否 当确定TNODE的分支标志与搜索关键字的相应位匹配时,TNODE具有根据子位图的子节点,以及(D)当确定TNODE没有子节点时,读取内部 TNODE的位图,根据内部位图计算TNODE中最长的匹配前缀,以及指向TNODE中的叶阵列的指针,使用计算结果更新当前最佳匹配指针,并计算叶节点的地址 (LNODE) nt最佳匹配指针。

    • The invention relates to a method for network domain name resolution, the domain name comprises a first portion domain name and a second portion domain name, and the resolution method comprising following steps: In a first network system, resolving the first portion domain name into a first network address; In the first network system, searching for a first network node corresponding to the first network address according to the resolved first network address; In a second network system, resolving the second portion domain name into a second network node address, and the domain name resolution system of the second network system being independent of the domain name resolution system of the first network system. As the resolution structure of the domain name in the Intranet is independent of the resolution structure of the domain name in the Internet, the IP address of the Intranet will not occupy the IP address resource of the Internet.
    • 本发明涉及一种网络域名解析方法,该域名包括第一部分域名和第二部分域名,该解析方法包括以下步骤:在第一网络系统中,将第一部分域名解析为 第一个网络地址; 在第一网络系统中,根据解决的第一网络地址搜索对应于第一网络地址的第一网络节点; 在第二网络系统中,将第二部分域名解析为第二网络节点地址,第二网络系统的域名解析系统独立于第一网络系统的域名解析系统。 由于Intranet域名解析结构与互联网域名解析结构无关,因此Intranet的IP地址不会占用Internet的IP地址资源。
