perfSONAR User Q&A and Other Discussion

[Sarah Larsen <>]

ESnet (Energy Sciences Network) is proud to announce the availability of iperf-3.17.1. This release fixes problems with version numbers in several places. It is functionally identical to iperf-3.17.

iperf3 is a tool for measuring the maximum TCP, UDP, and SCTP throughput along a path, allowing for the tuning of various parameters and reporting measurements such as throughput, jitter, and datagram packet loss.  It is fully supported on Linux, FreeBSD, and macOS.  It may run on other platforms as well, although it has not received the same attention and testing.  Note that iperf3 is not compatible with, and will not interoperate with, version 2 or earlier of iperf, although the two versions can co-exist on the same hosts and networks. 

The source code for iperf 3.17.1 is available at:
