iperf

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

Iperf usage Summary Iperf is a performance measurement tool for TCP/IP and UDP/IP. It provides network throughput information, as well as statistics such as vibration, packet loss rate, maximum segment, and maximum transmission unit size; this helps us test network performance and locate network bottlenecks. Iperf is the client that sends data to the server.The s

What is iperf? Iperf is a network performance testing tool. Iperf can test the maximum TCP bandwidth and report UDP bandwidth, latency jitter, and packet loss. Specific functions include TCP Measure network bandwidth Report the size and observations of MSS/MTU values Supports TCP Window value buffering through socket Multith

Iperf is a performance measurement tool for TCP/IP and UDP/IP. It provides network throughput information, as well as statistics such as vibration, packet loss rate, maximum segment, and maximum transmission unit size; this helps us test network performance and locate network bottlenecks. Parameter description -S starts in server mode. For example: iperf-s -C is started in client mode. The host is the serve

Using Iperf for throughput testing in mininet is a common method, and the way to end Iperf server before is to run the Os.system (' pkill iperf ') command.But this way Iperf server is probably still running and has been killed, causing some of the bandwidth test results to fail to display.Google, found that the

For Iperf source parsing, I was based on the 2.0.5 version in Windows execution of the situation analysis, advocated to start first through the simple modification of the source code to enable it to run in the local compiler, so that you can print out some intermediate information, for understanding the logic of the source code, The process of program implementation can play a multiplier effect.Iperf is mainly divided into the following modules:

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:192.168.10.11192.168.10.12 [root@192.168.10.11 ~]# Yum Install http:/

Before being asked to test the network card bandwidth capability, found iperf this tool, recorded to prevent forgetting. Iperf is an open source cross-platform test bandwidth tool, Windows, Linux, MacOS ... All support, installation is also very convenient.1. InstallationAddress: https://iperf.fr/2. TestingSee: https://www.52os.net/articles/iperf-check-bandwidth.

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 is Iperf 2.0.5Get the virtual machine to perform the decompression and configure./configu

First, the WiFi module in the factory to carry out the throughput test, throughput indicators do not have to check the cause of repair.Ii. test methods on Windows XP1, to prepare two computers, a router, a computer with a wired connection routed LAN port, another computer with wireless connection routing2, the Iperf.exe software into the C:\Windows\System32 directory of two computers to facilitate the execution of IPERF commands under the cmd command
