Qosium Node

Qosium is software, but sometimes it is impossible to install any software in the target environment. Qosium Node solves the problem: it brings a measurement point to your network without software installation. Qosium Node is also a versatile addition to network testbeds.


Qosium Node is a standalone device for network quality and performance measurements. It is based on a small but powerful industry PC suitable for harsh conditions. All Qosium measurement software comes integrated with a permanent license. Controlling the device and measurements is easy with Node’s web UI.

The primary use case of Qosium Node is to bring a measurement point to a network where it is impossible to install Qosium measurement software. However, Node provides extensive possibilities for using it also as an active part of your network, e.g., to act as a test application server. In addition, Node includes network emulator functionalities for creating varying impairments (delay, jitter, and packet loss) for the connection quality.

The device comes in two versions, both containing Qosium GP. Another version of Node also includes Qosium Storage. Several accessories are available, e.g., a GNSSGlobal Navigation Satellite System
A general term under which all the different global satellite navigation systems (e.g., GPS, GLONASS, Galileo, BDS) fall.
device for positioning and accurate clock synchronization, different kind of brackets, and a handy hard case.

Scenario Examples

There are many ways to use Qosium Node. Here are some general high-level examples.

Usually, Qosium Nodes are used together with Qosium software instances. Node creates a measurement point in the network where you cannot install software. For example, a network device manages the connections of interest, but the device is closed, preventing Qosium software installations. The need for measurement and monitoring can also be a network segment or an entire network. The best way to connect Node in such a situation is to mirror the interesting traffic from a nearby switch.

If a mirrored connection is not possible or practical, Qosium Node can also be connected as an Ethernet bridge between network devices. This connection type also enables Node to be used as a network emulator. Qosium Node can, thus, be a part of a laboratory test setup, where Node creates intentional and controlled impairments in the connection.

Since Qosium Node is a complete computer, it can also act as a terminal or even a light server, becoming an active network member while enabling accurate measurements and monitoring. You can measure even by Qosium Nodes alone.
