Active Measurement Tools

Active measurement injects traffic into a network to measure properties about that network.

• ping - a simple RTTandloss measurement tool using ICMP ECHO messages
• fping - ping variant supporting concurrent measurement to multiple destinations
• SmokePing - nice graphical representation of RTT distribution and loss rate from periodic "pings"
• OWAMP - a protocol and tool for one-way measurements

There are several permanent infrastructures performing active measurements:

• HADES DFN-developed HADES Active Delay Evaluation System, deployed in GEANT/GEANT2 and DFN
• RIPE TTM
• QoSMetricsBoxes used in RENATER's Métrologie project
