Qosium

The Visual Tool for Network QoS

Qosium helps network administrators understand and visualize network performance, which facilitates locating bottlenecks and problem areas in networks.

Qosium’s output can also be used to trigger, for example, different kinds of quality-driven alerts and actions. Network devices can be made more intelligent and end-user friendly. For example, in wireless mobility management, why rely only on signal strength criterion, which does not reflect application quality well, as the real application quality can also be made available.

Passive Measurement for Production Environments

Qosium is a passive measurement and monitoring solution: It measures the QoS of real applications on your network without causing disruptions.

Qosium can be used in both setup and operation phase. It is ideal for use in production, since it only requires a tiny bandwidth for transmitting the QoS results. Qosium is beneficial throughout the whole life-cycle of networks.

Active measurement tools, on the other hand, generate artificial traffic for the measurement, putting strain on the network. Active tools are more suitable for the initial development phase.

From Quality of Service to Quality of Experience

Quality of Experience indicates users’ satisfaction with the applications they are using over the network. In the end, it’s the most important indicator for network performance.

QoEQuality of Experience
Indicates the overall performance of a network application, and how user’s experience is affected by the network conditions. is not just about end-customers: Remote operators, for example, perform worse in their daily work if network performance doesn’t meet sufficient level. Whenever a human is interacting with a network application, QoE is relevant.

Qosium has scientifically proven and user-test-based algorithms for accurate QoE evaluation of video and VoIP. In addition, a generic QoE algorithm is included, which allows you to specify your own QoS thresholds for obtaining a single QoE value about current quality.

Get Security and Assurance with Qosium.

Service availability and performance problems can deal a critical blow to network-critical businesses. Yet, these problems and their root causes are difficult to detect and verify.

Qosium is a solution for network administrators, network testing actors, application and solution developers, and device manufacturers. The same solution fulfills even the strictest requirements of different industry and logistics fields. For example, it enables monitoring and confirming that SLAService-Level Agreement
A commitment between a service provider and a client agreements in terms of network performance are met. Industry robots and IoT devices can be connected reliably and with quality that satisfies their applications.

If your business is to evaluate network performance, Qosium allows you to verify the performance with actual applications used without the need for generating artificial traffic for measuring.

Measurement Results

All statistics are collected in both directions, meaning that sent and received traffic can be evaluated separately. The results can be averaged or evaluated accurately per packet.

The most commonly used statistics of Qosium include QoS statistics, such as packet loss, delay, jitter (delay variation), and connection break statistics. Qosium also collects basic traffic statistics, such as load, the volume of data, and packet sizes.

Flow statistics include traffic flows traversing measurement node and per-flow load, duration, transmitted data, etc. QoE (pseudo-subjective analysis) can be collected for VoIP and video quality with PSQA in the MOS scale. Generic QoE algorithm is also available, which allows users to define their own QoS threshold values.

Average QoS Statistics

Results are averaged and presented in real-time with, e.g., one-second interval. In addition to basic QoS parameters, such as packet loss, delay, and jitter, Qosium has over 60 different result types.

Per-Packet QoS Analysis

Packet results give accurate QoS statistics for every single measured data packet.

Traffic Flows

A list of traffic flows gives an intuitive view of where and what kind of connections are active in the device.

Packet Capture

Qosium has the capacity to capture full packets for later study with packet analyzers, such as Wireshark.

How It Works

Are you interested in manual measurements or automatic monitoring? Use case sets the basis of what Qosium components you need to use.

Qosium is a distributed measurement solution, which is composed of three types of components: the measurement agent, measurement controllers, and results systems. From these components, the measurement agent and a measurement controller are always needed in a Qosium measurement, while a results system is typically involved only in larger installations.

The Measurement Agent

Qosium Probe is a light-weight measurement agent, which is installed to network devices from which QoS is desired to be measured.

Network devices can practically be anything that allow installing new software, including work stations, servers, routers, switches, mobile devices, and IoT devices. Measurement can be carried out at a single point. However, all the features of Qosium come into use when the measurement is between multiple points. Multipoint measurement enables measuring QoS performance end-to-end and over any part on the path.

Measurement Controllers

A measurement controller locates Qosium Probes in the network, parameterizes them, controls the measurement, and guides the results to be delivered where desired.

It can be a pure controller, in which case the results are processed elsewhere, or an analyzer, being capable of analyzing and visualizing the results in addition to the measurement control. Kaitotek offers three measurement controllers, and also an opportunity to develop a custom controller.

Qosium Scope is an analyzer for creating, controlling, and parameterizing Qosium manual measurements. In addition, Scope collects and visualizes results. All the features of Qosium are available on Scope.

Qosium Scopemon is a measurement controller for automated monitoring. This enables, for instance, continuous monitoring of a critical communications system, allowing immediate reactions if QoS decreases excessively.

Qosium Scope Lite is a command-line tool for controlling measurements. It includes also limited real-time visualization capabilities. Scope Lite is especially suitable for constrained systems and creating measurements through scripting.

A custom controller can be implemented by using the QMCPQoS Measurement Control Protocol

An interface in software, which allows a third party to interact with the software programmatically. for all their customers, enabling direct Qosium measurement control, e.g., from a network management solution.

Results Systems

The task of a results system is to gather and store the measurement results.

A separate results system is not a mandatory part of a Qosium measurement. Still, it becomes handy when the measurement setup is large or the use case if of automatic monitoring. In some cases, an advanced measurement controller also integrates a results system. Results systems may also incorporate centralized visualization and analysis functionalities.

Qosium Storage is the results system of Qosium. In addition to the dedicated database server, it includes a web user interface for visualization and accessing the results. Storage is especially useful when results data grows large, and accessing the data is wanted to be centralized.

Create a Measurement Point

Are you interested in Qosium, but external software installations are not possible in your environment? Don’t worry: we have a solution.

Qosium Node is a standalone measurement device containing Qosium measurement software with a permanent license. It creates a measurement point where no software can be installed. Nodes can be used alone, or they can be part of a larger Qosium setup for occasional measurements or continuous monitoring.
