sockperf - Man Page
SockPerf is a tool for network performance measurement written in C++.
1. Summary
SockPerf is a network testing tool oriented to measure network latency and also spikes of network latency. Tool can create UDP/TCP data streams and measure the throughput and latency of a network that is carrying them. SockPerf allows the user to define different parameters that can be used for testing a network, or alternately for optimizing or tuning a network. Tool provides a client and server functionality, and can measure the throughput and latency between the two end-points, either unidirectionally or bidirectionally. This utility can be used in Linux systems.
2. Introduction
People are often concerned about measuring the maximum data throughput rate of a communications link or network access. A typical method of performing a measurement is to transfer a 'large' file and measure the time taken to do so. The throughput is then calculated by dividing the file size by the time to get the throughput in megabits, kilobits, or bits per second. Unfortunately, the results of such an exercise will result in the goodput which is less than the maximum throughput, leading to people believing that their communications link is not operating correctly. In fact, there are many overheads accounted for in good case in addition to transmission overheads, including latency, TCP Receive Window size and machine limitations, which means the calculated goodput does not reflect the maximum achievable throughput.
Another important thing of tool capacity is latency measurement. Latency - is the time it takes packet to go from user space program on one machine to user space program on another machine. Being able to quantify latency in terms other than millisecond response time is important when determining the quality of a network. One of available tool that can help administrators do just that is Sockperf.
SockPerf works as an on-demand client and server test. How this works is that one system runs the Sockperf server over a specified port and another system functions as a client running the Sockperf client. The binaries are the same, and there is an option to have the role of client or server, so the roles can easily be reversed if necessary.
3. Overview
Sockperf tests UDP/TCP network connection and maintenance following functionality:
- Measure latency;
- Measure TX/RX bandwidth;
- Measure packet loss;
- Multicast;
- Multi-threaded;
features:
- Measure the RTT of packets in descrete way;
- Provide full log of packet times;
- Provide few modes to monitor multiple file descriptors as recvfrom/select/poll/epoll;
- Improved CPU utilization;
Initially the tool was developed to demonstrate advantages of Mellanox's Messaging Accelerator (VMA). VMA is a socket API based, dynamically linked, user space Linux library which serves to transparently enhance the performance of Multicast/UDP/TCP networking heavy applications over the InfiniBand and Ethernet network. More interested user can read detail information at http://www.mellanox.com. Actually Sockperf can be used natively, or with VMA acceleration and see the benefit of VMA.
SockPerf operates by sending packets from the client to the server, which then sends the packets back to the client. This measured round trip time is the route trip time (RTT) between the two machines on a specific network path. The average RTT is calculated by dividing the total number of packets that perform this round trip by some fixed period of time. The average latency for a given one-way path between the two machines is the average RTT divided by two.
SockPerf can work as server or execute under-load, ping-pong, playback and throughput tests and be a server or a client.
SockPerf can be launched in single point manner that is name as the first mode and using special formatted feed file named as the second mode.
Mode One:
$sockperf server -i 224.18.7.81 -p 5001 sockperf: == version #3.5-no.git == sockperf: [SERVER] listen on: [ 0] IP = 224.18.7.81 PORT = 5001 # UDP sockperf: Warmup stage (sending a few dummy messages)... sockperf: [tid 4701] using recvfrom() to block on socket(s
Mode Two:
$sockperf server -f conf.file -F e sockperf: == version #3.5-no.git == sockperf: [SERVER] listen on: [ 0] IP = 5.2.1.3 PORT = 6671 # TCP [ 1] IP = 5.2.1.3 PORT = 6672 # TCP [ 2] IP = 5.2.1.3 PORT = 6673 # TCP [ 3] IP = 5.2.1.3 PORT = 6674 # TCP [ 4] IP = 5.2.1.3 PORT = 6675 # TCP sockperf: Warmup stage (sending a few dummy messages)... sockperf: [tid 4805] using epoll() to block on socket(s)
Every line in feed file should have following format as
or

where
- [U|T] - UDP or TCP protocol;
- address - Internet Protocol (IP) address or host name (IPv6 addresses must be enclosed in square brackets);
- port - Port number;

SockPerf package contains few scripts that allow to generate special formatted file to launch tool in different configurations.
- filter.awk - can be used for filtering lines from the full log file based on given latency range;
- gen1.awk - this awk script generates playback files (it is for stable PPS playback file);
- gen2.awk - this awk script generates playback files using the input for this script is file with lines of the format: startTime; duration; startPPS; endPPS; msgSize (it is for linear increased and decreased PPS playback file);
create playback file using gen1.awk > pfile generated file: # ==== playback file for sockperf - generated by gen1.awk ==== #baseTime=1.000000; PPS=200000; runtime=1.000000; interval=0.000005; NUM_RECORDS=200000 # file contains 200000 records 1.000005000, 12 1.000010000, 12 1.000015000, 12 1.000020000, 12 1.000025000, 12 1.000030000, 12 1.000035000, 12 1.000040000, 12 ... 1.999950000, 12 1.999955000, 12 1.999960000, 12 1.999965000, 12 1.999970000, 12 1.999975000, 12 1.999980000, 12 1.999985000, 12 1.999990000, 12 1.999995000, 12 2.000000000, 12 #200000 records were written successfully start server on ipX start client using: ./sockperf ping-pong -i <ip-address> -p <port> --playback=pfile

5.2 Options to compile
5.3 How to install
Download sockperf-<version>.tar.gz.
Uncompress *.tar.gz file in Unix systems in the same folder with the file by runing the following command in the shell:
tar -zxvf sockperf-<version>.tar.gz
or 2 command:
gzip -d ./sockperf-<version>.tar.gz tar -xf ./sockperf-<version>.tar
The sockperf package uses the GNU autotools compilation and installation framework.
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure').
If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it.
The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'.
The simplest way to compile this package is:
- 1.
`cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself.
Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for.
$ ./configure --prefix=<path to install>
There are several options to ./config (or ./Configure) to customize the build:
To enable test scripts
$ ./configure --prefix=<path to install> --enable-test
To enable the documentation
$ ./configure --prefix=<path to install> --enable-doc
To enable the special scripts
$ ./configure --prefix=<path to install> --enable-tool
To compile with debug symbols and information:
$ ./configure --prefix=<path to install> --enable-debug
This will define the _DEBUG variable at compile time.
Type './configure --help' for a list of all the configure options. Some of the options are generic autoconf options, while the SockPerf specific options are prefixed with 'SOCKPERF:' in the help text.
- 2.
Type `make' to compile the package.
$ make
- 3.
Optionally, type `make check' to run any self-tests that come with the package.
- 4.
Type `make install' to install the programs and any data files and documentation.
$ make install
- 5.
You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.
