Einführung –

Netzwerk-Latenz und Bandbreite sind die beiden Metriken am ehesten von Interesse sein, wenn Sie ein Netzwerk-Benchmark. Auch wenn die meisten Service-und Produkt-Werbung konzentriert sich auf die Bandbreite, in Zeiten der Latenz kann eine wichtige Kennzahl sein.

** Was ist Bandbreite?

Bandbreite (BW) in Computer-Vernetzung bezieht sich auf die Datenrate durch eine Netzwerkverbindung oder Schnittstelle unterstützt. BW ist im Hinblick auf die Bits pro Sekunde (bps) gemessen.

** Was ist die Netzwerk-Latenz?

Die Latenz ist ein Maß für die zeitliche Verzögerung in einem System erlebt. Netzwerklatenz ist einfach definiert als die zeitliche Verzögerung beobachtet, wie Daten überträgt von einem Punkt zum anderen. Es gibt eine Reihe von Faktoren, die Netzwerk-Latenz beitragen. Dazu gehören Getriebe (Medium-Konnektivität), Entfernung, Router und Computer-Hardware Verzögerungen.

Liste der Projekte verwendet werden, um Netzwerk-Performance und Bandbreite testen –

1) bmon – Bandbreite überwachen und bewerten Schätzer, ist es basierte Konsole, Live-BW
2) bwbar – Bandbreiten-Nutzung in Text und grafischen Format
3) BWM-ng – Bandwidth Monitor NG (Next Generation leben BW, Konsolenzugang
4) dstat – Dstat ist ein Ersatz für vmstat iostat und ifstat.
5) iftop – Bandbreiten-Auslastung auf einem Interface, basierte Konsole
6) iperf – Führen Netzwerk-Durchsatz-Tests Wette zwei Host
7) ifstat – Bericht Interface Statistics
8) cbm – Color Bandwidth Meter, basierte Konsole
9) etherape – Grafische Netzwerkverkehr Browser
10) iptraf – Interaktive Bunte IP-LAN-Monitor, Konsole und GUI-basierte
11) netmrg – Es ist Daemon basiert, mySQL unterstützen, sammelt Daten von Geräten.
12) nuttcp – Netzwerk Performance-Messung Werkzeug
13) nepim

HINWEIS ~ Für einige von ihnen rpm oder deb-Paketen sind nicht möglich!

Schritt 1] Wie bei der Installation Redhat / RHCE, CentOS System und Dibian basierten System?

root@me:~# yum install netperf iperf nuttcp nepim lmbench

Comment faire pour tester les performances du réseau et de bande passante

By | | Comments 0 Comment

Introduction –

Temps de latence et de bande passante sont les deux mesures les plus susceptibles de présenter un intérêt pour vous un réseau de référence. Même si la plupart des services et la publicité des produits se concentre sur la bande passante, parfois le temps de latence peut être un plus important métriques.

** Qu’est-ce que la bande passante?

Bande passante (BW) en réseaux informatiques se réfère au taux de données pris en charge par une connexion réseau ou une interface. BW est mesurée en termes de bits par seconde (bps).

** Qu’est-ce que la latence du réseau?

La latence est une mesure du temps de retard connu dans un système. La latence du réseau est simplement défini comme le délai observé que transmet les données d’un point à un autre. Il ya un certain nombre de facteurs qui contribuent à la latence du réseau. Il s’agit notamment de la transmission (support de la connectivité), Distance, les routeurs et les retards de matériel informatique.

Liste des projets utilisés pour tester les performances du réseau et de bande passante –

1) bmon – surveiller la bande passante et estimateur de taux, il est basé console, vivent BW
2) bwbar – utilisation de bande passante dans le texte et les graphiques en format
3) bwm-ng – Bandwidth Monitor NG (Next Generation, vivent BW, console basée
4) dstat – Dstat est un remplacement pour vmstat, iostat et ifstat.
5) iftop – utilisation de bande passante sur une interface, en fonction de la console
6) iperf – Effectuer des tests de débit réseau parier deux hôtes
7) ifstat – Rapport interface de statistiques
8) cbm – Couleur Bandwidth Meter, console basée
9) etherape – navigateur graphique le trafic réseau
10) iptraf – Interactive coloré IP LAN Monitor, console et interface graphique basée
11) netmrg – Il est le démon, de soutien mySQL, recueille des données à partir de périphériques.
12) nuttcp – Réseau outil de mesure du rendement
13) nepim

NOTE ~ Pour certains d’entre eux de paquetages rpm ou deb ne sont pas disponibles!

Hoe te testen Netwerk performance en bandbreedte

Hoe te testen Netwerk performance en bandbreedte

By | | Comments 0 Comment

Inleiding –

Netwerk latency en bandbreedte zijn de twee statistieken het meest waarschijnlijk van belang zijn wanneer u benchmark een netwerk. Hoewel de meeste diensten en producten reclame richt zich op bandbreedte, soms de latentie kan worden een belangrijke maatstaf.

** Wat is bandbreedte?

Bandbreedte (BW) in computer netwerken verwijst naar de gegevens die ondersteund wordt door een netwerkverbinding of interface. BW wordt gemeten in termen van bits per seconde (bps).

** Wat is netwerk latency?

Latency is een maat voor de vertraging ervaren in een systeem. Netwerk latency is gewoon gedefinieerd als de vertraging waargenomen als de gegevens doorgeeft van het ene punt naar het andere. Er zijn een aantal factoren die bijdragen aan het netwerk latency. Deze omvatten de overbrenging (medium van connectiviteit), Afstand, routers en computer hardware vertragingen.

Lijst van projecten gebruikt om netwerk performance en bandbreedte test –

1) bmon – bandbreedte monitor en de snelheid schatter, is de console gebaseerde, live BW
2) bwbar – bandbreedte verbruik in tekst en grafische opmaak
3) bwm-ng – Monitor van de Bandbreedte NG (Next Generation, live BW, console gebaseerd
4) dstat – dstat is een vervanging voor vmstat, iostat en ifstat.
5) iftop – Bandbreedtegebruik op een interface, console gebaseerd
6) iperf – Voer netwerk throughput testen weddenschap met twee hosts
7) ifstat – Verslag interface statistieken
8) cbm – Kleur Bandwidth Meter, console gebaseerd
9) etherape – Grafische netwerkverkeer browser
10) iptraf – Interactieve Kleurrijke IP LAN Monitor, console en GUI-gebaseerde
11) netmrg – Het is daemon gebaseerd, ondersteuning voor MySQL, verzamelt gegevens van apparaten.
12) nuttcp – Netwerk performance measurement tool
13) nepim

OPMERKING ~ Voor sommige van hen rpm of deb-pakketten zijn niet beschikbaar!

Stap 1] Hoe te installeren op Redhat / RHCE, CentOS gebaseerd systeem en Dibian gebaseerd systeem?

如何测试网络的性能和带宽

By | | Comments 0 Comment

简介 –

网络延迟和带宽两个指标最有可能当你有兴趣的基准网络。即使大多数的服务和产品广告有时带宽，重点潜伏期可以是一个更重要指标。

**什么是带宽？

带宽（BW）指的是由网络数据传输率或接口连接在计算机网络支持。体重是衡量每秒位数（bps）的条款。

**什么是网络延迟？

延迟是一个时间延迟测量系统中的经验。网络延迟仅仅是指在一定时间的延时，数据从一个地方传输到另一个地方。有很多因素造成网络延迟数。这些措施包括传播（连接介质），距离，路由器和计算机硬件延迟。

名单用于测试网络的性能和带宽项目 –

1）bmon – 带宽监控和速度估计，它是基于控制台，活体重
2）bwbar – 带宽的使用在文本和图形格式
3）宝马-吴 – 带宽监视器吴（下一代，活体重，基于控制台
4）dstat – Dstat是vmstat的，iostat和ifstat更换。
5）iftop – 带宽接口上使用，基于控制台
6）的iperf – 执行网络吞吐量测试两个主机打赌
7）ifstat – 报告界面统计
8）煤层气 – 色彩带宽计，基于控制台
9）etherape – 图形化网络流量浏览器
10）iptraf – 交互式IP局域网彩色监视器，控制台和图形界面的
11）netmrg – 它是守护进程的基础上，MySQL的支持，从设备收集数据。
12）nuttcp – 网络性能测量工具
13）nepim

注意〜对于其中一些rpm或deb包不可用！

How to Test Network performance and Bandwidth

How to Test Network performance and Bandwidth

By | | Comments 1 comment

Introduction –

Network latency and Bandwidth are the two metrics most likely to be of interest when you benchmark a network. Even though most service and product advertising focuses on bandwidth, at times the latency can be a more important metric.

** What is Bandwidth?

Bandwidth (BW) in computer networking refers to the data rate supported by a network connection or interface. BW is measured in terms of bits per second (bps).

** What is Network latency?

Latency is a measure of time delay experienced in a system. Network latency is simply defined as the time delay observed as data transmits from one point to another. There are a number of factors that contribute to network latency. These include transmission(medium of connectivity), Distance, Routers and computer hardware delays.

List of Projects used to test Network performance and Bandwidth –

1) bmon – Bandwidth monitor and rate estimator, it is console based,live BW
2) bwbar – Bandwidth usage in Text and Graphical format
3) bwm-ng – Bandwidth Monitor NG (Next Generation, live BW, console based
4) dstat – Dstat is a replacement for vmstat, iostat and ifstat.
5) iftop – Bandwidth usage on an interface, console based
6) iperf – Perform Network throughput tests bet two host
7) ifstat – Report InterFace STATistics
8) cbm – Color Bandwidth Meter ,console based
9) etherape – Graphical network traffic browser
10) iptraf – Interactive Colorful IP LAN Monitor, console and GUI based
11) netmrg – It is daemon based, mySQL support, Gathers data from devices.
12) nuttcp – Network performance measurement tool
13) nepim – network performance

NOTE ~ For some of them rpm or deb packages are not available!

Step 1] How to install on Redhat/RHCE,CentOS based system and Dibian based system –

root@me:~# yum install netperf iperf nuttcp nepim lmbench

** Ubuntu –

root@me:~# apt-get install  bmon bwbar bwm-ng dstat cbm etherape iftop iperf ifstat iptraf netmrg

Step 2] How to use – bmon, bwm-ng, dstat, ifstat –

root@me:~# bmon
