Тестування пропускної здатності каналу за допомогою iPerf3

Background

Загальна інформація

iPerf3 - кросплатформова консольна клієнт-серверна утиліта, яка дозволяє генерувати TCP,
UDP та SCTP трафік для аналізу пропускної здатності мережі.

Список публічних iPerf3-серверів доступний на сторінці - Public iPerf3 Servers.
Завантажити утиліту можна тут - Download iPerf binaries.
Список ключів, з якими можна запускати утиліту, доступний на сторінці - iPerf 3 user documentation.

Базові параметри

Виміри здійснюються наступним чином:

- на хості test1 запускається iPerf3 в режимі "сервер":

[adm1n@test1 ~]$ iperf3 -s

- на хості test2 запускається iPerf3 в режимі "клієнт" із зазначенням ip-адреси "сервера":

[adm1n@test2 ~]$ iperf3 -c <ip-address of test1>

- через визначений час буде показано інформацію з вимірами.

Стандартно тест виконується в напрямку від "клієнта" до "сервера".

Ключі iPerf, які використовуються

Перелік ключів утиліти, які використовуються в прикладах нище:

-s, --server - запуск в режимі "сервер" з відображенням усієї інформації на екран;
-c, --client host - запуск в режимі "клієнт" з підключенням до вказаного хоста;
-p, --port n - порт, на якому "сервер" буде приймати з'єднання, стандартно 5201;
-i, --interval n - визначає в секундах періодичність відображення проміжних звітів;
-t, --time n -визначає час проведення тестування в секундах, стандартно 10 секунд;
-P, --parallel n - кількість паралельних потоків, стандартно 1;
-R, --reverse - запуск в reverse-режіме: "сервер" передає дані, "клієнт" приймає.

Хости для проведення тестів

Для тестування використовується три сервери с ethernet-підключеннями:
- server1 - 100 Mb/s [77.120.107.177] ;
- server2 - 1 Gb/s [77.120.98.58];
- server3 - 2 Gb/s (LACP 1Gb/s+1Gb/s | layer3+4) [77.120.98.57].

Тести для 100Mb/s ethernet port

Запускаємо iPerf3 на сервері server2 [1 Gb/s] в режимі "сервер":

[adm1n@server2 ~]$ iperf3 -s

Server listening on 5201
-----------------------------------------------------------

Запускаємо iPerf3 на сервері server1 [100 Mb/s] в режимі "клієнт" із зазначенням на "сервер" server2:
