Network Testing: How to Test Network Performance
Our networks are always changing and evolving. Network Testing for higher speeds, better application and network device performance, and after a new service deployment or migration, helps us understand the impact of changes on our network. In this article, we’re running you through how to test network performance using Network Testing and Monitoring tools.
- What is Network Testing?
- Use a Dedicated Performance Testing Software
- Deploy Monitoring Agents for Network Testing
- Collect Network Data
- Analyze Historical Network Data
- Identify Network Problems
- Start Network Testing
Network Testing (or network performance testing), similar to Software Testing, is the process of analyzing and testing your network to identify bugs and performance issues, evaluate large network changes, and measure network performance.
Even the most robust networks experience network problems. That’s why before and after every new service migration or deployment, every new application or network device, and honestly - just as a continuous practice, perform network testing using Network Monitoring to detect and troubleshoot problems as soon as they happen.
Here’s how to set up network testing in just a few minutes!
Network testing can be demanding for a network admin. Knowing how to test a network requires a substantial amount of resources and manual effort. But, network monitoring tools can help.
Most traditional network monitoring solutions are passive, and only really monitor devices to notify you if they're up and running or not. But to actually test your network, you need to do better!
An active network monitoring software, like Obkio, continuously tests network (aka network performance testing) by measuring end-to-end performance from the end-user perspective with key network metrics.
With continuous network testing using Obkio, you get more detailed information about network problems affecting your network performance and impacting your end-users.

Network Monitoring Agents exchange synthetic traffic to continuously monitor network speed, core network metrics, identify network problems, collect historical data, and let you know how your network is performing at all times.
For network testing (or network performance testing) with Obkio, it’s important to set up monitoring agents in your key network locations like on your workstation, at your company's head office, branch office, data center, private and public clouds, etc.

Once you’ve deployed Obkio Monitoring Agents in key network locations, they will test and measure key network metrics like jitter, packet loss, latency, VoIP Quality, throughput and QoE, and display them on Obkio’s Network Response Time Graph.
Testing these network metrics allows you to proactively identify any performance degradation in your network, which may be a sign of a network issue arising, or an intermittent network problem in hiding.
Obkio will also automatically alert you of events like packet loss between certain sites, or users experiencing high levels of jitter during VoIP calls, and more.
One of the main use cases for network testing (network performance testing) is to test your network when substantial changes occur.
Analyzing historical performance data is key to understanding how your network is performing before, after, and during big changes to your network infrastructure.
Obkio measures and collects historical network performance data for you so you can analyze, compare, and troubleshoot performance from the past.
Go back in time to compare network performance before and after a new service migration or deployment, or pin a time range to find and troubleshoot intermittent network problems that pop up sporadically.

As we mentioned earlier, another common use case for network testing is to identify network issues or bugs which are bound to happen, even in the best performing networks.
To identify the cause, source, time, and location of network problems, you can use network troubleshooting tools like:
Speed Tests: which allow you to validate if the bandwidth you need is readily available.
Prioritization and QoS: which increases network efficiency in the event of network congestion and prioritizes applications more critical or sensitive to performance problems such as VoIP (including VoIP PBX or video.
Network Device Monitoring: to get detailed information about the health of network devices such as firewalls, routers, switches and wifi access points

With our growing reliance on a high performing network to run cloud applications, communicate virtually and manage our businesses, network testing and monitoring is more important than ever.
With a network monitoring solution, you can continuously test your network so you always have visibility over changes, problems, and areas for improvement.
