CableLabs Certifies First Cable Modem with Low Latency DOCSIS® Support

Matt Schmitt
Principal Architect

Apr 1, 2021

CableLabs is pleased to announce that, for the first time, a DOCSIS® 3.1 specification–compliant cable modem that includes the Low Latency DOCSIS (LLD) set of features has become CableLabs Certified. This announcement represents a major milestone on the path toward 10G because LLD support is key to improving latency on DOCSIS networks, and improving latency is one of the pillars of 10G.

Starting with Certification Wave (CW) 134 in January, all DOCSIS 3.1 cable modems submitted for CableLabs certification are required to include support for the LLD feature set. Our Kyrio subsidiary recently finished testing the Motorola MG8725 from Minim, which was submitted for testing in that CW. The CableLabs Certification Board—made up of representatives from our member companies—then reviewed the results and determined that the device had met the requirements for CableLabs Certification.

The modem can be found on the Certified/Qualified Device List on the CableLabs website with an ID of MOTO1341. Any DOCSIS 3.1 cable modems added to that list in the future for CW 134 or later will also include support for the LLD feature set.

What Is Latency?

As described in our "Latency 101: Getting From There to Here" blog, latency refers to the time it takes for something to get from one point to another across a network. People experience this delay when doing things on the Internet, and it can come from myriad sources. Although latency performance often does not receive the same attention as speed, it’s one of the most noticeable aspects of a user’s online experience.

What Is Low Latency DOCSIS?

As described in our blog post “CableLabs Low Latency DOCSIS Technology Launches 10G Broadband into a New Era of Rapid Communication,” LLD technology is a set of new features for DOCSIS 3.1 (and future) equipment that can be added to already deployed devices via a software update. LLD can provide consistent low latency (as low as 1 millisecond) on the access network for the applications that need it. The user experience will be more consistent with much smaller delay variation.

Why Is Low Latency DOCSIS Important?

In our blog post “Rise of Cloud Gaming—Meeting the Challenges for ISPs,” we discussed applications such as online gaming and game streaming that can provide greatly improved user experiences with reduced, consistent latency. But latency isn’t just about gaming: Many work-from-home applications such as video conferencing can benefit from improved latency. And future technologies like interactive virtual experiences will require consistently low latencies as well.

What Is CableLabs Certification, and Why Does It Matter?

As detailed in our blog post “What’s in a Name? The Value of Certification/Qualification for Cable Operators,” in order for a device to become CableLabs Certified, Kyrio executes a series of tests to determine whether the device complies with a particular CableLabs specification. Once that testing is completed, the results are reviewed by the Certification Board to determine whether that device has earned CableLabs Certification status.

CableLabs Certification, therefore, serves as a mark of quality, indicating that a given device complies with the requirements of our specifications and enabling cable operators to roll out the device. CableLabs and Kyrio offer a number of options to assist vendors through the certification process—as detailed in our blog post “3 Tips on How to Make CableLabs Certification/Qualification Testing as Painless as Possible”—including interoperability events and device pre-testing.

A cable modem with LLD functionality that successfully completes CableLabs Certification represents a big step on the path to eventual wide deployment of these technologies, enabling a host of new applications and improved user experiences. We can’t wait to see the new ideas that will generate.

CableLabs’ Subsidiary Kyrio and SCTE•ISBE Combine Expertise

Mitchell Ashley
President & General Manager, Kyrio

Oct 26, 2018

This week Kyrio staff attended SCTE•ISBE Cable-Tec Expo 2018 in Atlanta, Georgia. Cable-Tec Expo is an important event for our industry, bringing together a diverse group of technical and operational staff, technology creators, and suppliers of technologies created for use in the field—all at one industry event. It’s a way that we “connect the dots” for the broadband, wireless and security technologies Kyrio works with every day.

The testing we perform in our labs is one of the most valuable and insightful functions Kyrio provides to device manufacturers and service providers. We go to great lengths to understand how wireless and broadband technologies will perform in customers’ homes and businesses before, during and after they are deployed, often in millions of locations.

But nothing takes the place of seeing installers and technicians actually use the technologies we work with—hands on, in the real world. Frequently the best way for Kyrio staff to understand a day in the life of a field service technician or installer is to participate in a ride-along program. We do this because some of the best information about the technologies Kyrio tests in the labs is to see it in action by technicians in the field.

Now we’re taking this connect-the-dots approach to a whole new level. At Cable-Tec Expo 2018 yesterday morning, we revealed that Kyrio and SCTE•ISBE are working closely together to leverage our respective experience and knowledge in testing, certifying, securing and installing broadband and wireless equipment.

The first two areas of focus are Wi-Fi and DOCSIS® 3.1. Security is another potential area of collaboration. A cross-functional team is now being formed to solidify these areas of collaboration and provide ongoing guidance of our work together.

Kyrio will collaborate with SCTE•ISBE to create content, training and guides on the innovations on which Kyrio works. These resources will be made available to SCTE•ISBE members, enabling field and operational staff to have insight to ensure the successful deployment of technologies and their ongoing operations. Kyrio and SCTE•ISBE will also elevate problem areas experienced in the field (such as Wi-Fi in the home, for example) and share insights from the testing we perform. All of this will take the form of new videos and other educational formats for technology training and knowledge sharing. Together we can collaboratively investigate challenging issues, better understand how technology works in the field and influence testing and specifications processes during technology development.

What’s unique about this collaboration is what our two organizations bring together. SCTE•ISBE’s members are from the operational side of the business. This includes installers and technicians—people who work in the field, install the technology in customers’ homes and businesses. They have in-depth knowledge and first-hand experience seeing the technology work, which helps them develop troubleshooting techniques when challenges occur.

Kyrio works with technologies during their development, when products are ready to go to market and in cooperation with buyers and manufacturers during procurement, lab testing and field trials. Kyrio has unique insights into how the products are designed to work, how well they meet specifications, their level of interoperability with other devices and as part of the larger network, and which use cases operators and manufacturers intend to support when products are deployed.

I’m excited to be working with Mark Dzuban, President and CEO of SCTE•ISBE, to bring the capabilities of our teams together in some unique and powerful ways. Stay tuned to both Kyrio and SCTE•ISBE channels for news and updates resulting from our work together.

Successful OnGo Interoperability Test Event Held at CableLabs

Luther Smith
Director, Wireless Technology

Sep 5, 2018

During the week of August 27th CBRS-Alliance members and government representatives gathered in Louisville Colorado at the CableLabs facility for the first CBRS OnGo™ Interoperability Test Event. The attendees consisted of a Spectrum Access System (SAS) Administrator, Citizen Band Service Device (CBSD) vendors, Domain Proxy (DP) vendors, End Unit Device (EUD) vendors and operators and representatives of various government agencies.

CBRS-Alliance is an industry organization focused on driving the development, commercialization and adoption of OnGo™ shared spectrum solutions. The CBRS Alliance enables a robust ecosystem through the management of the OnGo brand, and the OnGo Certification Program. OnGo provides an in-door and out-door LTE network that is cost-effective and can be used for either data offload or private LTE and IOT applications.

The testing covered critical functions of the CBRS ecosystem, “end-to-end” test cases, and operational flexibility. The success of the event shows the maturity of the WinnForum specification and the overall readiness of all parts of the ecosystem for Initial Commercial Deployment (ICD). This event demonstrated the ease that CBSD vendors were able to register on a SAS and become operational. One such example was a CBSD vendor and SAS administrator that had not previously interacted were able to exchange information, register the CBSD and became fully operational all in less than 30 minutes.

While certification testing focuses on protocol testing with test harnesses, this event was conducted as a real-world deployed system. With over 850 scheduled test interactions, as well as several additional unscheduled test scenarios being executed, we observed no equipment failures or unexplained results. The test cases included “end-to-end” scenarios in which EUD attached to operational CBSDs and were able to successfully access and surf the Internet.

“Last week’s Interoperability Test Event was an incredible illustration of the power of collaboration and as a result of this cooperation – across member organizations, industry liaisons and the CBRS Alliance Working Groups – we proved that the OnGo ecosystem will offer tremendous benefits to end users across market verticals,” said Alan Ewing, CBRS Alliance Executive Director. “Notably, this event provided the first ever connection attempt between certain devices and SAS'. The connections were quickly made in each case and underscored the quality of the OnGo specifications and the maturity of vendor implementations.”

In addition to hosting this event, CableLabs through Kyrio (a wholly owned subsidiary of CableLabs) supplied the PKI certificates used during the event which allowed the CBSDs and DPs to quickly switch between the SASs without having to reload new certificates. This greatly reduced the testing time and eliminated issues related to incorrect certificates being used.

As an active member of the CBRS-Alliance, CableLabs continues to contribute to the specification work that the CBRS-Alliance is developing. CableLabs also holds a position of co-lead in the Test and Certification working group which was fundamental input on this Interoperability Test Event.
