1. INDIANAUNIVERSITYINDIANAUNIVERSITY Indiana University Animated Traffic Map Software Presented to the International Task Force at the Spring Internet2 Members Meeting By Chris Robb

2. INDIANAUNIVERSITYINDIANAUNIVERSITY 2 Current Monitoring Tools Two of the most widely used traffic monitors are open source offerings from Tobias Oetiker MRTG (http://www.mrtg.org) –In wide use on many major networks –Good for quick traffic graphs –Five minute polling interval RRDtool (http://http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/) –Less understood than MRTG –Doesn’t come packaged with a data collector –RRD format is designed to be more extensible and easily accessed than MRTG logfile formats –Jeff Allen’s excellent Cricket toolset uses RRD as a backend while providing a collector and highly customizable configuration format Neither of these tools allow you to easily see the state of your entire network. Indiana University needed a solution.

4. INDIANAUNIVERSITYINDIANAUNIVERSITY 4 Features Web based monitoring Colors indicate amount of link saturation Text-boxes indicate amount of traffic on each link Can monitor any type of data with any type of programmatically accessible backend Open source code free to non-profit organizations!!!

5. INDIANAUNIVERSITYINDIANAUNIVERSITY 5 Requirements Unix-based – we’ve run it exclusively on Linux systems, but should work on any Un*x implementation GD Library (http://www.boutell.com/gd/) Data collection backend – MRTG, RRDtool, homebrewed collector, etc.

6. INDIANAUNIVERSITYINDIANAUNIVERSITY 6 How to Get It ATM software is currently being maintained by IU’s Telecommunications Software Engineering Group (TSEG) Apply for a license at: http://tseg.uits.iu.edu/dist/wxmap/index.html

7. INDIANAUNIVERSITYINDIANAUNIVERSITY 7 Support for Creating a New Map Creation of a new map is fairly straight-forward, but tedious (I’ll address that in a second) A sample configuration has been included with the distribution No direct support from IU, but there is a discussion board at: http://tseg.uits.iu.edu/dist/wxmap/wxmapbbs.html Please share your scripts with the community!

8. INDIANAUNIVERSITYINDIANAUNIVERSITY 8 Future Directions The current map creation process is quite cumbersome and tedious On Friday, May 10 th, TSEG will be releasing a set of DIA plugins to aid in map item placement. Built in high speed data collector Links that can bend – currently you’re limited to straight lines

9. INDIANAUNIVERSITYINDIANAUNIVERSITY 9 Now go get it! Feel free to apply for the software and share your implementation on the discussion board In addition to the ATM software, we have released the Abilene Router Proxy code Thanks and Enjoy!
