iPerf(Internet Performance Working Group )是专业的网络测试工具,基于TCP/IP和UDP/IP协议,测量两个节点之间TCP和UDP端口的网络带宽,支持提供网络延迟、丢包率等统计信息。 实现机制相当简单:它创建 TCP 和 UDP 流,并将流量从一台主机发送到另一台主机,然后向用户报告最大带宽。这允许用户确定网络吞吐量和最高带宽...
iperf_err(sp->test, "OUT OF ORDER - incoming packet = %zu and received packet = %d AND SP = %d", pcount, sp->packet_count, sp->socket); } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. pcount是从接收到的udp数据包中读取的序列号(这个序列号不是tcp的序列号,udp头部没有这个字段,所以应...
UDP performance: Some problems have been noticed with iperf3 on the ESnet 100G testbed at high UDP rates (above 10Gbps). The symptom is that on any particular run of iperf3 the receiver reports a loss rate of about 20%, regardless of the -b option used on the client side. This ...
iperf3 is slightly more robust to out-of-order packets during UDP connection setup in --reverse mode (#914 / #1123 / #1182 / #1212 / #1260). iperf3 will now use different ports for each direction when the --cport and --bdir options are set (#1249 / #1259). ...

UDP packets per second now reports the correct number of packets, by reporting NET_SOFTERROR if there's a EAGAIN/EINTR errno if no data was sent (#1367/PR#1379). Several segmentation faults related to threading were fixed. One wherepthread_cancelwas called on an improperly initialized thread ...
It can test TCP, UDP, or SCTP throughput. To perform an iperf3 test the user must establish both a server and a client. The iperf3 executable contains both client and server functionality. An iperf3 server can be started using either of the -s or --server command-line parameters, for ...
Withiperf, you can tune several parameters associated with timing, buffers, and protocols such as TCP, UDP, and SCTP. It comes in handy fornetwork performance tuningoperations. In order to acquire maximum or rather improved network performance, you need to increase the throughput as well as the...
Iperf 是美国伊利诺斯大学(University of Illinois)开发的一种网络性能测试工具。可以用来测试网络节点间TCP或UDP连接的性能,包括带宽、延时抖动(jitter,适用于UDP)以 及误码率(适用于UDP)等。关于Iperf的下载、安装以及详细的使用方法,可以参照: http://dast.nlanr.net/Projects/Iperf/ ...
Using the iperf3 dissector, you can verify out-of-order UDP packets in iperf3 yourself. I used it to troubleshoot a network situation where i got LOTS of duplicate frames. iperf3 dumped so many error messages that i thought it was a bug in iperf3 itself. Using the dissector, i could...
