iPerf 工具

iPerf-主动测量IP网络上最大可实现带宽的工具,支持TCP, UDP, SCTP with IPv4 and IPv6。

iPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, buffers > and protocols (TCP, UDP, SCTP with IPv4 and IPv6). For each test it reports the bandwidth, loss, and other parameters. This is a new implementation that shares >no code with the original iPerf and also is not backwards compatible. iPerf was orginally developed by NLANR/DAST. iPerf3 is principally developed by ESnet / >Lawrence Berkeley National Laboratory. It is released under a three-clause BSD license.
