iperf bandwidth test

What is IPERF/IPERF3?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 imple

Background information: In debugging the network, often need to detect the maximum bandwidth between the two hosts, I have been using the Iperf command, the effect is very good and accurate, but found some Yun-wei friends do not know that there is this tool, so intend to write a brief introduction to the article. Specific actions: Operating system: CentOS6.5 x86_64 MinimalServer:192.168.10.11192.168.10.1

"Summary"Iperf is a network performance testing tool, it can be easily used for SDN network bandwidth and network quality testing,Iperf Support protocol, timing, Configuration adjustment of buffers and other parameters, reporting tcp/udp Maximum bandwidth, delay jitter, packet loss and other statistics. 1

Many companies are upgrading their wireless networks to 802.11n to achieve greater throughput, wider coverage, and greater reliability, while ensuring the performance of wireless LANs (WLANs) is particularly important to ensure adequate network capacity and coverage. Below, we'll explore how to measure network performance through IPERF, a tool that is easy to use to measure tcp/udp throughput, loss, and latency. Pre-application Preparation

implementation function, which is explained clearly in the comment on the source code line and is no longer described here;Timestamp This class has only one member variable of type Timeval, the member function includes getting the current time, adding and reducing time, comparing two time successively, etc., it is easier to understand.Timestamps are used to assign values to each sending packet during the data transfer process, indicating when the packet was sent, and in the condition that the-I

IperfIperf is a tool for measuring network throughput performance, which can test the throughput of TCP or UDP, and in order to perform iperf testing, a connection must be established between the server (to discard traffic) and the client (to generate traffic).The Iperf has TCP and UDP two test modes, respectively, as

The driver is also written almost, so it is necessary to test the performance? The iperf is used for testing, and the test results of the next s3c6410+ks8851 are compared.1, Iperf How to cross-compile?https://iperf.fr/ official website always to be reliable, the test version
