Hi, after an Iperf test, I got following results:
[root@ ~]# iperf -c 192.168.2.1 -u -fm -t60 -d -b 10m ------------------------------------------------------------ Server listening on UDP port 5001 Receiving 1470 byte datagrams UDP buffer size: 0.04 MByte (default) ------------------------------------------------------------ ------------------------------------------------------------ Client connecting to 192.168.2.1, UDP port 5001 Sending 1470 byte datagrams UDP buffer size: 0.01 MByte (default) ------------------------------------------------------------ [ 4] local 192.168.1.1 port 32284 connected with 192.168.2.1 port 5001 [ 3] local 192.168.1.1 port 5001 connected with 192.168.2.1 port 52428 [ ID] Interval Transfer Bandwidth [ 4] 0.0-60.0 sec 71.5 MBytes 10.0 Mbits/sec [ 4] Sent 51021 datagrams [ 4] Server Report: [ 4] 0.0-59.9 sec 69.8 MBytes 9.77 Mbits/sec 0.112 ms 1259/51020 (2.5%) [ 4] 0.0-59.9 sec 1 datagrams received out-of-order [ 3] 0.0-60.0 sec 69.8 MBytes 9.77 Mbits/sec 0.030 ms 1200/51021 (2.4%) [ 3] 0.0-60.0 sec 1 datagrams received out-of-order [root@ ~]# How did Iperf calculate, that it sent 71.5 MBytes? I mean it says it has sent 51021 datagrams and one datagram is 1470B so I should have sent 75MB instead(51021*1470/10^6). Or if I calculate transferred data based on bandwidth, then it also shows 75Mbps(10/8*60). Or is the transferred data pure data without the UDP and IP headers? If yes, then transferred data size should still be more than 71.5MB.. regards, Martin ------------------------------------------------------------------------------ Slashdot TV. Video for Nerds.
