Abstract
A method and apparatus is provided for comparing and sorting data strings of different lengths, in a given character set, and modifying the data such that queries can be run using different search trees. Three different search trees are provided, including: a binary prefix tree and two m_way tree structures, a static m_way prefix tree and a dynamic m_way prefix tree. The data strings may be prefixes of addresses in TCP/IP protocols and searching may be performed using a host address of a computer network. The method further provides for transmitting packet information associated with the network address. Additionally, switching packets in layer and of the TCP/IP protocol and sending the packets to designated ports of a device is provided. The method may also provide differentiated service or data protection, such as a firewall, based on packet classification information.
