This Page contains information about UDPmon which can be used for measuring the performance of 100 Mbit, Gigabit and 10 Gigabit switches, as well as network connections involving LANs, MANs and WANs. There are also links to results of tests made on Gigabit switches for the ATLAS experiment, and some tests made using the LANs, MANs and WANs of NetNorthWest, Manchester Campus and SuperJANET.
There is a simple write-up that describes the programs and the command options. The latest version of the code is available as the udpmon tar file and requires the libhj package which is also available as the libhj tar file. The udpmon file also contains some sample command files showing how UDPmon may be run; they produce a set of text files containing the results. There is an Excel spreadsheet file that will accept these files and plot them for you! The spreadsheet contains a simple macro that reads a data file into a worksheet and renames the worksheet.
The programs use the standard socket interface and do not require root access. They are designed to measure end-to-end performance of the network and its components by using UDP packets. The code has mainly been used on Linux, although some programs have been ported to Suns. To get fine time bins for individual network measurements, the cycle counter on the Pentium chip has been used. The programs are used in pairs to make the following measurements:
From UDPmon version 1.0.0 automake was used and the distribution was split into two tarballs: the udpmon tool and the supporting library libhj. The udpmon-a.b.c tarball creates directory udpmon-a.b.c and libhj-l.m.n creates directory libhj-l.m.n. For installation and compilation in your home directory having downloaded the corresponding UDPmon and library files start by cd to the library directory then:
./configure --prefix=$HOME
make install
$HOME/include and $HOME/lib are created. Then cd to the directory containing udpmon and do:
./configure --prefix=$HOME --with-hj-location=$HOME
make install
$HOME/sbin is created with the UDPmon programs.
Prior to version 1.0.0 the tar file contained both tool and library and when unpacked, created two directories:
udpmon_vxx containing the test programs and "src_vxx" containing library functions. xx is the version number of the kit.
