Cable operators all around the world are working hard to provide their customers with high speed data services by making use of (Euro)DOCSIS® 3.0 technology. An important problem however is that as of today none of the available CMTS solutions are EuroDOCSIS™ 3.0 Qualified. As an operator you want...
byteblower.intro_.jpg One, single solution, endless possibilities The ByteBlower network traffic generator/analyzer tool helps you perform exhaustive tests on IP networks and networking equipment. The possibilities are endless. Focused on performing tests up to layer 5 of the OSI model, including...
When talking about throughput, all sorts of numbers get tossed around. However, it is crucial to clarify what data you are talking about when demonstrating and comparing values. What’s included, and what’s not?
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 first post of a three-part series, introduces both.
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 second post of a three-part series shows which impairments are available and how they can be configured.
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 final post of a three-part series shows how to set up an impairment node in practice.
The 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 much the same. In this post, I want to give a bit of back story on the throughput test that we've added to the 2.7.0 ByteBlower release. You'll also get a sneak peek at what is coming in the next release.
Wi-Fi 6 is the newest standard for Wi-Fi networks – but are devices making full use of its capabilities? We tested a handful of Wi-Fi 6 devices to find out.
