zelf haal ik vaak rond de 10-12ms heel soms 8 alleen vind ik dit al vrij laag
toen ik net bij ziggo zat in 2016 was er ook nog geen docsis 3.1 zo actief in gebruik als nu en was het makkelijk 20-30ms
engelse uitleg waarom de latency door docsis 3.1 verbetert kan worden
Can we have good throughput, low packet loss and low latency? At CableLabs, we have been researching a technology called Active Queue Management where the cable modem and CMTS will keep a close eye on how full their buffers are getting, and as soon as they detect that TCP is keeping the buffer full, they will drop just enough packets to send TCP the signal that it needs to slow down, so that more appropriate buffer levels can be maintained.
This technology shows such promise for radically improving the broadband user experience, that we've mandated it be included in DOCSIS 3.1 equipment (both cable modem and CMTS). We've also amended the DOCSIS 3.0 specification to strongly recommend that vendors add it to existing equipment (via firmware upgrade) if possible.
On the cable modem, we took it a step further and require that devices implement an Active Queue Management algorithm that we've specially designed to optimize performance over DOCSIS links. This algorithm is based on an approach developed by Cisco Systems, called "Proportional Integral Enhanced Active Queue Management" (or, more commonly known by its less tongue-tying acronym: PIE), and incorporates original ideas from CableLabs and several of our technology partners to improve its use in cable broadband networks.
By implementing Active Queue Management, cable networks will be able to reduce these transient buffering latencies by hundreds or thousands of milliseconds, which translates into massive reductions in page load times, and significant reductions in delays and glitches in interactive applications like video conferencing and online gaming, all while maintaining great throughput and low packet loss.
Active Queue Management: A little thing that can make a huge impact.
