Measurements
This section covers the design and execution of network measurement campaigns using the nxthdr probing infrastructure. You’ll learn how to configure probes and understand the trade-offs and implications of different measurement strategies.
To get started quickly, check out our interactive tutorial and send your first probes directly from our network.
What Are Active Measurements?
Active measurements involve sending controlled traffic across the Internet to collect data about network performance, topology, and behavior. They are widely used by researchers, network operators, and engineers to:
- Understand routing dynamics
- Diagnose connectivity or latency issues
- Evaluate the impact of routing or configuration changes
- Map Internet paths and detect anomalies
They are called active because they intentionally generate traffic, unlike passive measurements, which analyze existing traffic flows without injecting new packets. Examples of passive measurements include monitoring BGP updates, RPKI state, or observing flow data on routers.
Credits
To ensure fair and responsible use of the platform, we limit the number of probes each user can send by using a credit system.
Each user is allocated 10,000 measurement credits per day, which are reset at midnight UTC.
- 1 credit = 1 probe
- This means you can send up to
10,000probes per day across all your experiments.
If you need more credits, please contact us.
