Qosium is a software for passive Quality of Service (QoS) and Quality of Experience (QoE) performance measurement/monitoring. No matter whether you use wired or wireless networks, Qosium lets you discover the real performance, in real time.
Qosium takes you to a new level in measurement and analysis of network performance. The measurements are passive, which does not cause overhead to networks. Qosium Probe reveals how your applications really perceive the network performance. It 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 kind 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 doesn’t reflect application quality well, as the real application quality can also be made available.
Qosium is a solution for network administrators, application and solution developers, and device manufacturers. The same solution fulfils even the strictest requirements of different industry and logistics fields. For example, it enables monitoring and confirming that SLA 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 need for generating artificial traffic for measuring.
How it works
Measurements are based on Qosium Probes located in different nodes in networks. These can be, for example, application servers, routers, mobile devices, and IoT devices. Measurement can be carried out in a single point, but the key feature of Qosium is a multipoint measurement, which enables measuring performance end-to-end and on any path between.
Measurements are carried out passively. This means that existing traffic is measured, instead of generating traffic to the network that is measured. This reveals the true performance for currently active applications using the network.
Qosium Scope, or a third-party software developed upon Qosium's API, is used to control measurements and collect results.
Support for QoE
Qosium Probe is a QoS and traffic flow measurement solution, but it includes also algorithms for evaluating QoE based on QoS parameters measured. Scientifically proved and user-test-based algorithms for accurate QoE evaluation of video and VoIP are integrated. In addition, also a generic QoE algorithm is included, which allows users to specify their own QoS thresholds for obtaining a single QoE value about current quality. No more monitoring of different QoS parameters separately, but the actual quality can be seen through a single value.
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:
- Packet loss
- Jitter (delay variation)
- Connection break statistics
- Volume of data
- Packet sizes
- Traffic flows traversing measurement node
- Per flow: load, duration, transmitted data, etc.
QoE (pseudo-subjective analysis)
- VoIP and video quality with PSQA in the MOS scale
- Generic QoE algorithm, which allows users to define their own QoS threshold values
In addition, Qosium measures a number of other parameters and optionally has a full DPI capability.
