When we released a new version of the ByteBlower traffic generator a few years ago we started getting user reports saying the TCP traffic flows mysteriously “stopped” after a short time. Some users told us the traffic stopped after 10 to 30 seconds. Other users told us the TCP flows stopped immediately. For those users...
Our first impressions of Wi-Fi 6 devices

It has also been called High-Efficiency Wireless (HEW), and these two names are more marketable alternatives to 802.11ax, which refers to the specification standard. Wi-Fi 6 is the...
Will 5G ensure safer driving with connected cars?
The adoption of new 5G standards in Belgium is a hot topic. Many supporters cite braking distances for self-driving cars as a good reason to kick 4G to the curb, as 5G ensures significantly lower latency than 4G, as well as guaranteed quality of service. But is latency really putting...
Latency in a nutshell, and what makes it so important
VOIP solutions and video chat apps are part of our business and personal lives – and online multiplayer games have become mainstream hobbies. To enable these applications, huge volumes of data are being exchanged online at ever-more-massive rates. A delay in the transmission of data – i.e. latency – can have...
Two ways to test network throughput using ByteBlower
he first step after installing a new network is often to determine its maximum throughput. At the DOCSIS 3.1 interop that we organized a couple of months ago, several participants stayed after to get the highest throughput on their modems. When new lab equipment is delivered to a customer, it’s...
