As of LCOS version 9.20, LCOS features the tool "iPerf" for performance measurements over network routes. It performs bandwidth measurements either one-way or two-way. Iperf can be started directly from any LANCOM device. The LANCOM device is able to act as a client and as a server (UDP/TCP). The LCOS implementation is based on iPerf2.
iPerf can be configured either via LANconfig or via the command-line console.
