Training Overview

Internet has grown tremendous the last 20 years. The more possibilities the internet provided; the more bandwidth was needed. However, certain services can’t be improved by just adding additional bandwidth. These services need real-time behaviour. Think at applications such as web meetings, live video, online gaming or medical applications. For these, latency and jitter are at least equally important as throughput. With Low Latency DOCSIS, the cable access network is not going to be the weakest link in the latency chain.
DOCSIS networks can have round trip time spikes of 1 second under heavy load. Latency sensitive application will perform badly in such situations while the bandwidth is not the issue. Low Latency DOCSIS is added to the DOCSIS 3.1 specification to handle this problem. It will keep the round trip time around 1 millisecond (for specific services), even under heavy load.

The goal of this course is to provide insight into how LLD operates, what the impact is on services and how this can be tested. 

It is recommended that the attendee already has a good knowledge of DOCSIS to fully benefit of attending this course.

  • Achieve a good understanding of the benefits and challenges of LLD
  • After attending this course, the attendee will be capable of understanding DOCSIS 3.1 LLD concepts, configuration and testing
