RIPE Atlas is the biggest internet measurement network composed of more than 8000 probes distributed worldwide. The new RIPE Atlas streaming service allows you to tap into the real-time data flow of all the collected public results. Every time our system receives a data point or a probe connectivity event occurs, it's also delivered to the clients that are "tuned in" to that result stream. This feature is implemented using web sockets.

RIPE Atlas streamingSome numbers (April 2015) 3
• 8,200+ probes connected (119 Anchors)
• 2,500+ results collected per second
• 35,000+ user-defined measurements weekly
- Five types of user-defined measurements available to
probe hosts and RIPE NCC members: ping, traceroute,

After the measurement results are collected, processed and
stored, they are downloadable in JSON format or visualisable
some minutes later

It would be nice to monitor a network in
real-time!

RIPE Atlas streamingNew: RIPE Atlas streaming
• RIPE Atlas streaming is a new
architecture that allows users to
receive the measurement results as
soon as they are sent by the probes
!
• Publish/subscribe through sockets
• Measurement results and connection
