PerfSONAR toolkit is used in the FIBRE testbed to monitor the control plane among all Brazilian islands.

Each Brazilian island has a pair of dedicated PerfSONAR servers to monitor the available bandwidth and network delay.

See the PerfSONAR Dashboard at: http://ps.fibre.org.br

Configuration of monitoring tests

One-way delay (using OWAMP)
This test is continuously performed because it consumes very low bandwidth
Metrics provided: uni-directional delay, packet loss, jitter, duplicate packets
The test send 10 packets / second (0.1 seconds with pauses between every packet). To minimize the amount of stored data while enabling more detailed statistical analysis, measurements are saved as histograms. Every histogram represents the measurements made in the range of 1min.
Uses TCP to the control channel and UDP to send test packets.

Traceroute
Protocol: UDP
Frequency: every 5 minutes
max_ttl: 64
Size of packets sent: 40 bytes (not counting the IP / UDP headers)
