6 sockperfSockPerf is a tool for network performance measurement written
7 in C++.

10 SockPerf is a network testing tool oriented to measure network latency
11 and also spikes of network latency. Tool can create UDP/TCP data
12 streams and measure the throughput and latency of a network that is
13 carrying them. SockPerf allows the user to define different parameters
14 that can be used for testing a network, or alternately for optimizing
15 or tuning a network. Tool provides a client and server functionality,
16 and can measure the throughput and latency between the two end-points,
17 either unidirectionally or bidirectionally. This utility can be used in
18 Linux systems.
19
21 People are often concerned about measuring the maximum data throughput
22 rate of a communications link or network access. A typical method of
23 performing a measurement is to transfer a 'large' file and measure the
24 time taken to do so. The throughput is then calculated by dividing the
25 file size by the time to get the throughput in megabits, kilobits, or
26 bits per second. Unfortunately, the results of such an exercise will
27 result in the goodput which is less than the maximum throughput,
28 leading to people believing that their communications link is not
29 operating correctly. In fact, there are many overheads accounted for in
30 good case in addition to transmission overheads, including latency, TCP
31 Receive Window size and machine limitations, which means the calculated
32 goodput does not reflect the maximum achievable throughput.
33 Another important thing of tool capacity is latency measurement.
35 Latency - is the time it takes packet to go from user space program on
36 one machine to user space program on another machine. Being able to
37 quantify latency in terms other than millisecond response time is
38 important when determining the quality of a network. One of available
39 tool that can help administrators do just that is Sockperf.
40 SockPerf works as an on-demand client and server test. How this works
42 is that one system runs the Sockperf server over a specified port and
43 another system functions as a client running the Sockperf client. The
44 binaries are the same, and there is an option to have the role of
45 client or server, so the roles can easily be reversed if necessary.
46
48 Sockperf tests UDP/TCP network connection and maintenance following
49 functionality:
50 · Measure latency;
52 · Measure TX/RX bandwidth;
54 · Measure packet loss;
56 · Multicast;
58 · Multi-threaded;
60 features:
62 · Measure the RTT of packets in descrete way;
64 · Provide full log of packet times;
66 · Provide few modes to monitor multiple file descriptors as
68 recvfrom/select/poll/epoll;
69 · Improved CPU utilization;
71 Initially the tool was developed to demonstrate advantages of
73 Mellanox's Messaging Accelerator (VMA). VMA is a socket API based,
74 dynamically linked, user space Linux library which serves to
75 transparently enhance the performance of Multicast/UDP/TCP networking
76 heavy applications over the InfiniBand and Ethernet network. More
77 interested user can read detail information at http://www.mellanox.com.
78 Actually Sockperf can be used natively, or with VMA acceleration and
79 see the benefit of VMA.
80 SockPerf operates by sending packets from the client to the server,
82 which then sends the packets back to the client. This measured round
83 trip time is the route trip time (RTT) between the two machines on a
84 specific network path. The average RTT is calculated by dividing the
85 total number of packets that perform this round trip by some fixed
86 period of time. The average latency for a given one-way path between
87 the two machines is the average RTT divided by two.
88 SockPerf can work as server or execute under-load, ping-pong, playback
90 and throughput tests and be a server or a client.
91 SockPerf can be launched in single point manner that is name as the
93 first mode and using special formatted feed file named as the second
94 mode.
95 Mode One:
97 $sockperf server -i 224.18.7.81 -p 5001
99 sockperf: == version #3.5-no.git ==
100 sockperf: [SERVER] listen on:
101 [ 0] IP = 224.18.7.81 PORT = 5001 # UDP
102 sockperf: Warmup stage (sending a few dummy messages)...
103 sockperf: [tid 4701] using recvfrom() to block on socket(s
104 Mode Two:
107 $sockperf server -f conf.file -F e
109 sockperf: == version #3.5-no.git ==
110 sockperf: [SERVER] listen on:
111 [ 0] IP = 5.2.1.3 PORT = 6671 # TCP
112 [ 1] IP = 5.2.1.3 PORT = 6672 # TCP
113 [ 2] IP = 5.2.1.3 PORT = 6673 # TCP
114 [ 3] IP = 5.2.1.3 PORT = 6674 # TCP
115 [ 4] IP = 5.2.1.3 PORT = 6675 # TCP
116 sockperf: Warmup stage (sending a few dummy messages)...
117 sockperf: [tid 4805] using epoll() to block on socket(s)

469 5.1 Requirements
470 What you will need to compile sockperf on Unix systems
471 · perl 5.8+ (used by the automake tools)
473 · GNU make tools: automake 1.7+, autoconf 2.57+, m4 1.4+ and libtool
475 1.4+
476 · A Compiler, among those tested are:
478 · gcc4+ (Ubuntu)
480 · gcc4+ (Red Hat)
482 5.2 Options to compile
484 5.3 How to install
485 Download sockperf-<version>.tar.gz.
486 Uncompress *.tar.gz file in Unix systems in the same folder with the
488 file by runing the following command in the shell:
489 tar -zxvf sockperf-<version>.tar.gz
491 or 2 command:
494 gzip -d ./sockperf-<version>.tar.gz
496 tar -xf ./sockperf-<version>.tar
497 The sockperf package uses the GNU autotools compilation and
500 installation framework.
501 These are generic installation instructions.
503 The `configure' shell script attempts to guess correct values for
505 various system-dependent variables used during compilation. It uses
506 those values to create a `Makefile' in each directory of the package.
507 It may also create one or more `.h' files containing system-dependent
508 definitions. Finally, it creates a shell script `config.status' that
509 you can run in the future to recreate the current configuration, a file
510 `config.cache' that saves the results of its tests to speed up
511 reconfiguring, and a file `config.log' containing compiler output
512 (useful mainly for debugging `configure').
513 If you need to do unusual things to compile the package, please try to
515 figure out how `configure' could check whether to do them, and mail
516 diffs or instructions to the address given in the `README' so they can
517 be considered for the next release. If at some point `config.cache'
518 contains results you don't want to keep, you may remove or edit it.
519 The file `configure.in' is used to create `configure' by a program
521 called `autoconf'. You only need `configure.in' if you want to change
522 it or regenerate `configure' using a newer version of `autoconf'.
523 The simplest way to compile this package is:
525 1. `cd' to the directory containing the package's source code and type
527 `./configure' to configure the package for your system. If you're
528 using `csh' on an old version of System V, you might need to type
529 `sh ./configure' instead to prevent `csh' from trying to execute
530 `configure' itself.
531 Running `configure' takes awhile. While running, it prints some
533 messages telling which features it is checking for.
534 $ ./configure --prefix=<path to install>
536 There are several options to ./config (or ./Configure) to customize the
539 build:
540 To enable test scripts
542 $ ./configure --prefix=<path to install> --enable-test
544 To enable the documentation
547 $ ./configure --prefix=<path to install> --enable-doc
549 To enable the special scripts
552 $ ./configure --prefix=<path to install> --enable-tool
554 To compile with debug symbols and information:
557 $ ./configure --prefix=<path to install> --enable-debug
559 This will define the _DEBUG variable at compile time.
562 Type './configure --help' for a list of all the configure options. Some
564 of the options are generic autoconf options, while the SockPerf
565 specific options are prefixed with 'SOCKPERF:' in the help text.
566 2. Type `make' to compile the package.
568 $ make
570 3. Optionally, type `make check' to run any self-tests that come with
573 the package.
574 4. Type `make install' to install the programs and any data files and
576 documentation.
577 $ make install
579 5. You can remove the program binaries and object files from the
582 source code directory by typing `make clean'. To also remove the
583 files that `configure' created (so you can compile the package for
584 a different kind of computer), type `make distclean'. There is also
585 a `make maintainer-clean' target, but that is intended mainly for
586 the package's developers. If you use it, you may have to get all
587 sorts of other programs in order to regenerate files that came with
588 the distribution.
