README for Net-Patricia ----------------------- JCM::Net::Patricia - Patricia Trie perl module for fast IP address lookups DESCRIPTION ----------- This module uses a Patricia Trie data structure to quickly perform IP address prefix matching for applications such as IP subnet, network or routing table lookups. The data structure is based on a radix tree using a radix of two, so sometimes you see patricia implementations called "radix" as well. The term "Trie" is derived from the word "retrieval" but is pronounced like "try". Patricia stands for "Practical Algorithm to Retrieve Information Coded as Alphanumeric", and was first suggested for routing table lookups by Van Jacobsen. Patricia Trie performance characteristics are well-known as it has been employed for routing table lookups within the BSD kernel since the 4.3 Reno release. The BSD radix code is thoroughly described in "TCP/IP Illustrated, Volume 2" by Wright and Stevens and in the paper ``A Tree-Based Packet Routing Table for Berkeley Unix'' by Keith Sklower. Availability ------------ My "home" site for JCM::Net::Patricia is: https://github.com/jmaslak/JCM-Net-Patricia History ------- This module is forked from the awesome Net::Patricia module. The changes to Net::Patricia are the second argument passed to both the climb() and the climb_inorder() methods - the CIDR prefix being returned along with the data. This is intended to be a temporary module and will revert to being as light of weight of a wrapper around Net::Patricia when Net::Patricia implements similar functionality. Please check out Net::Patricia before using this code, and, if Net::Patricia serves your needs, please use that module instead. Installation ------------ This package extracts, builds, installs in the usual fashion, i.e.: $ gunzip -c .tar.gz |tar xf - $ cd $ perl Makefile.PL $ make $ make test # make install Requirements ------------ * perl version 5 -- This fork is maintained by Joel Maslak
