pytricia

A Python-based longest-prefix match lookup library for v4 and v6 network addresses.

Built upon Dave Plonka’s patricia library. Works with both Python 2 and 3, supports v4 and v6, and is a bit faster than other libraries out there (including pyradix, and SubnetTree). See the github page for documentation and performance numbers. Can be installed through standard Python tools like pip (name: pytricia). Available at http://github.com/jsommers/pytricia.

SLAm

A tool for multi-objective active monitoring

Publication: A framework for multi-objective SLA compliance monitoring (INFOCOM 2007 minisymposium), and Accurate and Efficient SLA Compliance Monitoring (ACM SIGCOMM 2007). Available upon request.

SoMeta

SPLAT

A Scatter and Phase-pLot Animation Tool.

Publication: SPLAT: a visualization tool for mining Internet measurements, PAM 2006. Available at http://cs.colgate.edu/~jsommers/splat.

Switchyard

A framework for facilitating systems-type projects in networking courses (or intro to systems courses). It’s a Python framework within which you write code to implement the logic for a network device such as a switch, router, or middle-device. It includes a comprehensive testing framework, and code can be deployed in live networks, too.
