Network Testing workshop:
Low Latency DOCSIS
On request
ā All trainings are offered as virtual sessions or in-person, on-demand or public, at Excentis or on-site. Highly interactive and with ample Q&A time! Predefined or tailored to your needs. Default language in English, but we also offer trainings in Dutch, French and German.
Overview
Low Latency DOCSIS or LLD provides a cost-effective means of leveraging the existing hybrid fiber-coaxial (HFC) network to provide a better internet experience for latency-sensitive applications without any negative impact on other applications.Ā
DOCSIS 3.1 that has been deployed in the field experiences typical latency performance of around 10 milliseconds (ms) on the Access Network link. However, under heavy load, the link can experience delay spikes up to 1s or higher.
First tests activating LLD look very promising but these tests also showed that there is a huge variety of scenarios to test before deploying. Besides defining the right matrix of tests to execute it is also crucial to have good means to analyse and compare results.
Our LLD workshop tackles this by providing hands-on excercises to test and analyse. Such a workshop can be offered with standard content orĀ based on a mutual predefined scope and time. A workshop is still a training but can be guided by the trainees. They are however not intended as consultancy to solve individual problems.Ā
The workshops that we currently offer are the ByteBlower, (Euro)DOCSIS, Wi-Fi and LLD workshop. Workshops are always tailored on a specific demand and the content need to be agreed on prior to getting an individual offer.Ā
Workshops are only available when a company contracts to host it for a group of participants.
Target audience for this workshop are all people involved with testing latency metrics.Ā Ā
We offer custom workshops to suit your requirements and relevance.
An example of a 1-day workshop providing a detailed overview of testing Low Latency DOCSIS using ByteBlower:
- ByteBlower components, the flexibility of the GUI, the power of the API and the ByteBlower Test Framework offering the simulation of realistic traffic patterns;
- Use of a CMTS/CCAP to configure LLD;
- Manipulation of modem config files;
- Analysis of ByteBlower output (e.g. CCDF graphs, voice MOS scores, video stream perception, game quality,
video conferencing quality); - Q&A between attendees and trainer(s).Ā Ā
Course Overview
We offer custom workshops to suit your requirements and relevance.
An example workshop day could be:
Ā
PART 1: AQM:
- Testing Active Queue management (AQM) with different latency targets
PART 2: Configuring and measuring LLD metrics:
- Getting a view on different LLD functionalities and configurations.
Tests involved PGS, C-SF versus LL-SF, QP, different speeds and a lot moreĀ
PART 3: Vendor specific implementation of LLD (when useful)Ā Ā
- See the effect of CMTS specific LLD algorithmsĀ Ā
PART 4: Use of tools, Q&A discussionsĀ
- Example use of Prometheus and Grafana for real-time and historical ByteBlower results in the lab environmentĀ

Case: Low Latency DOCSIS training for Virgin Media O2
In July 2022, Excentis organized its first Low Latency DOCSIS (LLD) training program for Virgin Media O2.
The training consisted of a half-day DOCSIS refresher, a half-day theory session on LDD and a full-day hands-on workshop with exercises using our ByteBlower Network Traffic Generator, ByteBlower GUI and a vCCAP with cable modems set up in our lab.
