Network testing refers to an investigation conducted by tech experts. The tests provide information about the condition of an existing network through quantitative and qualitative measurements. It tests for and records certain behaviours or processes of networks that, when combined, define their overall performance. Through network testing, you ensure your network configuration works as designed.
Network testing is similar to software testing, which offers an objective view of the software, allowing the user to appreciate and understand how it works. It contrasts with software testing, however, as it is only conducted after the configuration of the network. This is why Matrium Technologies believes network testing is an essential step – you can find out if the network still performs long after its implementation.
Via active network monitoring, network testing detects issues as soon as they occur. Below are a few instances where network testing is most useful for validating your network design:
Today’s existing network systems are more advanced, often made with the latest technology and complex programming. However, they are still prone to cybersecurity attacks, especially where a large organisation is concerned.
With network testing, you can gauge the performance and effectiveness of your network’s security. Network testing provides compliance audits, critical analysis as well as tactical testing. It can emulate realistic traffic volumes as well as a comprehensive range of threat and attack scenarios.
Quality of Service (QoS)
All networks are created differently. Each is tailored according to the nature and requirements of the client. With QoS, you can provide a level of service across a network so that it meets the needs of the users.
Applying a QoS configuration to a network is complex. Several aspects of the configuration can go wrong, so network testing is the next step after a QoS. It verifies that the network is marking, queuing and classifying your traffic correctly.
Firewall Rule Updates
Firewall systems prevent unauthorised access from or to a private network. It’s a good habit to check that a new firewall functions well and whether it’s allowing or blocking specific traffic that’s bad for your network.
Network testing is a great way to verify a successful firewall update. A port scanner or a TCP-based ping test works well for firewall-related concerns.
Routing Policy Change
Network complexity has a tremendous effect on your routing table, the place where you store all your routing information. The more extensive the network, the higher the risk that a change in routing policy will harm your routing table.
Through network testing, you can detect flaws with a route policy change. Entrusting your network testing to a distributed monitoring agent helps you confirm that a routing policy change is modifying your routing table successfully.
A balance between complexity and optimisation are the key factors to an excellent network. Ensuring the correct choice is dependent on many factors that are often a challenge. With the help of skilled engineers and efficient network testing, you’ll have the support you need to keep the network infrastructure running smoothly.
