#Test bandwidth code

New: Output in JSON format (-J option).New: Use SCTP rather than TCP (-sctp option).New: Set congestion control algorithm (-C option).New: Set target bandwidth for UDP and (new) TCP (-b option).

A server accepts a single client simultaneously (iPerf3) multiple clients simultaneously (iPerf2).Use representative streams to test out how link layer compression affects your achievable bandwidth (-F option).Print periodic, intermediate bandwidth, jitter, and loss reports at specified intervals (-i option).Can run for specified time (-t option), rather than a set amount of data to transfer (-n or -k option).Server handles multiple connections, rather than quitting after a single test.Client and server can have multiple simultaneous connections (-P option).Cross-platform: Windows, Linux, Android, MacOS X, FreeBSD, OpenBSD, NetBSD, VxWorks, Solaris.Client can create UDP streams of specified bandwidth.Support for TCP window size via socket buffers.Report MSS/MTU size and observed read sizes.It is released under a three-clause BSD license. iPerf was orginally developed by NLANR/DAST.

#Test bandwidth code

This is a new implementation that shares no code with the original iPerf andĪlso is not backwards compatible. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6).įor each test it reports the bandwidth, loss, and other parameters. IPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks.
