Fluke Electronics is buying Visual Networks for £45m, partly to offer companies a voice over IP (VoIP) network...
Visual Networks sells products that help firms to do network capacity planning, locate network problems and collect data on application performance and network security.
In March, the company launched a suite of products for measuring VoIP performance and to help companies to optimise their networks to carry such calls.
The products measure VoIP availability, delay, and bandwidth use. VoIP allows companies to make free or cheaper calls over IP-based infrastructure and avoid the more expensive public switched telephone network (PSTN).
Other products on offer from the company can measure web-based application performance.
The company will now become part of the Fluke Networks business, which is an established player in the network testing products market.
