Kaitotek Oy (Ltd), which was founded early this year, is continuing the development of software, begun by VTT Technical Research Centre of Finland, for measuring and monitoring the quality of service of networks. The measurement tool provides real-time data on measures such as bit rates, delays, and data transfer interruptions in network connections.
"Passive measurement provides us with a tool for rapidly picturing how data networks perform from the perspective of various applications and end users, regardless of whether a voice, video or data application is being used," says Jarmo Prokkola, a former VTT employee and now the CEO of Kaitotek.
The various commercially available tools based on active measurement are poorly suited to measuring the flow of data over existing networks. Networks are becoming more diverse; in security and mission-critical systems, in particular, understanding the current quality of network services is essential to enabling applications to adjust to the situation.
Kaitotek is engaged in the further development and maintenance of the technology developed by VTT, which is now known as Qosium. This technology transfer will guarantee that the measurement software is available and supported in the future.
VTT has recently used Kaitotek's measurement software for purposes such as testing and measuring the 5G test network. Then, for example, a measurement campaign carried out in IKEA Centres' Matkus Shopping Centre provided information on how well mobile phone networks provided in Finland, and the shopping centre's own wireless network, functioned in the shopping centre.
"The necessary improvements can be made on the basis of measurements, and re-measurement can verify that networks are functioning properly. In addition, continuous monitoring can ensure that performance meets the needs of various applications, such as phone calls and real-time data transfer," says Jyrki Huusko, Research Team Leader at VTT.
The technology transfer has enabled the large-scale commercialisation of the measurement solution and customer-driven product development to begin.
