NIPAP

the Neat IP Address Planner - a powerful yet simple IP address planning tool for larger service providers with the need to handle large amounts of prefixes

easybuild-framework

EasyBuild is a software installation framework in Python that allows you to install software in a structured and robust way.

prefixanalyzer

PrefixAnalyzer is a tool for analyzing the AS-path graphs regarding an IP prefix. Basic instructions on how to get the system running: Creating the prefix graphs is a three step process, using files which should be located in the top directory of the project: Run PerPrefixLogger.py. This reads ... [More] the archives from RouteViews and databases all the archives. You will need to install MySQL and get the Python MySQLDb library. You will also need to set the config directories in Util.py before you run this file. (Note: start small when you play with this. An entire years worth of BGP updates for the routeviews monitor takes up almost 400GB in MySQL. If you want to be able to generate statistics on a per prefix basis, you need to figure out a way to store information about each prefix individually (~500,000 distinct prefixes) and be able to access them quickly.) Run StateGenerator.py. This program reads from the stored data and generates statistics/info about each prefix. This also uses MySQL, but this database takes up very little space comparitively. Run SvgGenerator.py. This reads the data from the database created by StateGenerator.py and creates an SVG file for every prefix. All 3 of the programs have controls so you can do them for a small subset of prefixes, date ranges, etc. Every file in the root src/ folder is executable. Here's what the other ones do: fetch_archives.py - connect to a monitor and download the bgp updates convert_archives.py - convert the fetched from their downloaded format (not sure what it is, but it's not human readable and is converted using a program called routebtoa) to bzip'ed plain text. IPDump.py - dump a list of every ip address to a text file ASParser.py - Parses a downloaded copy of http://bgp.potaroo.net/cidr/autnums.html and inserts the ASnumber/name pairs into the database This project and page is currently under construction.

portage-prefix-app-emacs-overlay

My Gentoo app-emacs overlays for portage-prefix .

prefix-list

Simple data structure to maintains all prefixes of a string lexicographically ordered. It's similar to a suffix array (suffix tree) but it can be built on-line. For each prefix it is also possible to know its longest common prefix with its successor (next bigger element) and it is useful in ... [More] some kind of context-based symbol-ranking text compression algorithms. It is the implementation of the idea in: CPM'99, LNCS 1645, pp. 150-162, 1999 [Less]

gratuitous-radix-trie

Simple and small C header-based library with a C++ wrapper. Interfaces will include basic set/get, longest prefix, and iterator support.

rangeselector

Custom Ant Selector that uses integer prefix on resource name.

hongqn-gentoo-overlay

It's a personal Gentoo overlay for hongqn. As I'm a happy Mac user now, this portage will mostly hold some gentoo prefix ebuilds. Hope opensource this can help other gentoo prefix users. If you have any question or feedback, please use the "Issues" tab.
