Largest Active Measurements Network: RIPE Atlas
0 likes874 views
RIPE Atlas is the largest active measurements network, consisting of over 2,900 probes located in 108 countries. The probes conduct built-in measurements like pings and traceroutes to root nameservers and RIPE infrastructure multiple times per day. Members and probe hosts can also define custom measurements. The document discusses the types of measurements available, current probe deployment and coverage, and how RIPE Atlas was used to study the impact of Hurricane Sandy. It promotes getting involved by hosting a probe or becoming a sponsor.

- 16. • For accurate maps we need many vantage points - Small probes - Easily deployable - USB powered - 24 x 365 capable • Hosted and sponsored by organisations and end- users - ISPs, Internet Exchange Points, individuals... - Free of charge for volunteers who host individual probes Hardware Devices: Probes 16 16Friday, April 19, 2013
- 17. Who Can Perform Which Measurements? • RIPE NCC is performing “built-in” measurements _ From all the probes, towards root name servers and our infrastructure _ Periodically: few times a day (55 million / day) _ pings, traceroutes and DNS queries _ Data stored on Hbase/Hadoop clusters _ Results available to everyone! • Probe hosts and RIPE NCC members perform customised measurements using the targets of their choice and desired frequency _ (5 million / day) • Anchoring measurements coming up soon _ Each probe will measure 4-5 “anchors” as a regional baseline _ RIPE Atlas anchor hosts can perform their own customized measurements 17 17Friday, April 19, 2013
- 18. Credits System • By hosting a probe, a host earns credits _ As a reward for making his/her probe available to other users, for performing measurements from that probe towards any target _ Hosts earn 21,000+ credits per day, as long as the probe is connected • In order to schedule customised measurements, users spend credits _ ping costs 10 credits, traceroute 20, etc. _ Daily limit applies • Credits system introduced to ensure fairness and protect system from overload • Extra credits can be earned by: being a RIPE NCC member, hosting a RIPE Atlas anchor or sponsoring multiple probes 18 18Friday, April 19, 2013
