A picture is worth a thousand words?
• Analytical– Usage patterns & levels
• Diagnostic– Error rates, geographically located
• Promotional Tool– Compelling picture of usage– Unattended demo mode

A view to deployment…• Extensible
– No geographic limits– Modular architecture– Intermediate data format– Well documented
• Meets privacy concerns– Temporal blurring– ‘image processing’ (optional)

Future• JRS deployment
• Adaptation to other JANET services– JVCS– Jiscmail?
• Accommodate RADSEC– Trialling IF-MAP as a roaming publication

An invitation• Prototype code available to any
interested NREN– Would ultimately love to see a pan-
European version of the map
• Presenting this work in more detail at TNC; would be nice to have other implementations to include…
