  1. A RIS-based System for the Visualization of the Routing Flaps RIPE43 Maurizio Patrignani

  2. credits • Fabrizio Lombardozziwas the first designer and implementor of the system • Giuseppe Di Battistais the coordinator of the Computer Network Research Group of the 3rd Univ. of Rome (www.dia.uniroma3.it/~compunet) • Ilaria De Marinis,Federico Mariani, and Maurizio Pizzoniaare also involved in the development of the system

  3. prev experiences: hermes www.dia.uniroma3.it/~hermes hermesproduces maps of AS interconnections starting from static sources (mainly RPSL data)

  4. prev experiences: nethunter www.dia.uniroma3.it/~nethunt nethuntervisualizes the IP layer interconnections, integrating data from several traceroute servers

  5. prev experiences: polyphemus www.dia.uniroma3.it/~polyph polyphemusdiscovers and visualizes OSPF networks (uses MIBs)

  6. prev experiences: logviewer www.dia.uniroma3.it/~cipriani/logviewer logviewerhelps Web Administrators to understand how users access web sites (uses web server logs)

  7. picture -  X prev experiences: summary structural and behavioral data • starts from some kind of (network) data and studies its visualization and exploration • requires both computer networks and information visualization expertise internet

  8. Routing Information Service flapviewer purposes • use data available from the RIS service • visualize routing instabilities for the routes originated by a specified autonomous system within a given time period

  9. flapviewer potential users • ISP operators • for easily perceiving where and when the instabilities occur • networking teachers • for showing BGP foundamentals to their students • content delivery providers • for visually monitoring the switches of the information flow around their targets

  23. hierarchical visualization • the role of each AS is very clear • information about the sequence of the events is lost • BGP updates flow from right to left (?)

  24. orthogonal visualization we used http://www.dia.uniroma3.it/~gdt/ • supports orthogonal drawings • handles constraints

  25. future targets (2003) • march 2003: flapviewer ver. 2.0 released • improved visualization capabilities • improved efficiency • better use of cache • allow batch tasks (monitoring purposes) • improved stability • enhanced modularity • corrected known bugs and glitches • improved usability and friendliness • possible usage of the Oregon RouteViews data

  26. future targets (2003) • may 2003: hermes ver. 2.0 released • tools for checking the consistency of registry information against real life BGP routing data • july 2003: as-view(?) ver. 1.0 released • visualization of AS interconnections showing their hierarchical relationships

  27. next generation tools • we are working to port hermes in IPv6 • we would be happy to port flapviewer in IPv6 as soon as IPv6 RIS will be available
