  7. Why Measure This Way? • There are lots of bad measurements out there! – Ping - what does it measure?? – From single locations … • People (press, regulators) use them! • Better Measurements are Needed – From multiple points – Real DNS traffic 7 Daniel Karrenberg . ccTLD Sofia October 2006 . http://www.ripe.net

  16. How to Read the Graphs • Server View – shows quality of service provided by the server to all probes • Domain View – summarises quality of service provided by all servers serving a domain • (Probe View) – shows quality of service provided by all servers at a particular probe location 16 Daniel Karrenberg . ccTLD Sofia October 2006 . http://www.ripe.net

  17. What is Measured • Real DNS queries • Poisson distributed, ~60/hour/server/probe • From 60+ probes around the world • Response time • Server instance ID (anycast, load balancing) • SOA version number • Server software version 17 Daniel Karrenberg . ccTLD Sofia October 2006 . http://www.ripe.net

  18. What is Not Measured • DNS queries used in actual name resolution • Total DNS serv ice quality, e.g. ‘ user experience ’ • global service quality: 60+ points, RIPE region bias • Effects that last less than about a minute But still very comprehensive measurements! 18 Daniel Karrenberg . ccTLD Sofia October 2006 . http://www.ripe.net
