An easy dashboard for DOCSIS and network traffic
Have you ever noticed how a significant portion of your time is lost switching between different tools? Take a modem test, for example. The DOCSIS stats are found on one console-terminal, the traffic generator has a GUI, and probably a few more dashboards or admin panels. While each of these...
Is low latency the holy grail to fantastic user experience?

Some users told us the traffic stopped after 10 to 30 seconds. Other users told us the TCP flows stopped immediately. For those users...
What happens if you introduce latency to a Remote PHY setup?
It’s been a while since we first explained how to use Linux Traffic Control as an impairment node to introduce latency to a test setup. More recently, the discussion surrounding Low Latency DOCSIS triggered us to investigate what would happen if we used an impairment node to introduce latency between the CCAP...
