Our first impressions of Wi-Fi 6 devices
Do the newest smartphones and routers support the new standard? You’ll likely come across three different terms when reading about Wi-Fi 6. 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...
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...
Common pitfalls when testing NAT
I am not going to tell how to test the NAT Section (Agriculture, Rural Development and Environment) from the European Economic and Social committee. I believe you’re more interested in solutions for problems when testing Network Address Translation (NAT) routers. This post intends to help you in handling issues when testing (devices behind) NAT...
Use Linux Traffic Control as impairment node in a test environment (part 3)
Rigorously testing a network device or distributed service requires complex, realistic network test environments. Linux Traffic Control (tc) with Network Emulation (netem) provides the building blocks to create an impairment node that simulates such networks. This three-part series describes how an impairment node can be set up using Linux Traffic...
