bwping-udp

About

bwping-udp is a tool for wireless performance measurement. It was developed in the WINET laboratory (http://www.winet.dcc.ufmg.br) at UFMG to collect metrics relevant to wireless links that are not collected by classic tools (i.e. Iperf and others). bwping-udp can be used on ordinary Ethernet, IEEE 802.11 wireless links, fiber optics and even sattelite links between two hosts. The payload can be set to jumbo frame size up to more than 9000 bytes if needed.

For the impatient

Download the source files using git clone or download the zip file from github.

$ git clone https://github.com/h3dema/bwping-udp

Go to the directory of the uncompressed files (cd ./bwping-udp). To compile and install bwping, simply run:

% make
% sudo make install

To get help, run:

% man bwping-client
% man bwping-server

No known bugs. Report bugs to [email protected]

Features Wish List

• Implement slow-start + congestion avoidance mechanisms in UDP to measure full bandwidth of a link
• Parallel streams
• Reverse test mode – Server sends, client receives
• Set target bandwidth to n bits/sec
• Output in JSON format
• Set CPU affinity
• Format to print bandwidth numbers in (Kbits/sec, Kbytes/sec, Mbits/sec, MBytes/sec)
• Capture the signal and noise in the wireless interface at the AP
