CableLabs Certifies First Cable Modem with Low Latency DOCSIS® Support
April 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 […]

Remote PHY 101: Why the Industry Is Working Together to Take Things Apart
March 9, 2021
In our previous CableLabs 101 post about Distributed Access Architecture (DAA), we discussed the benefits of distributing key network functions throughout the cable access network to optimize its performance. Today, we delve deeper into Remote PHY—one of the earliest DAA solutions that cable operators are deploying to increase their network’s bandwidth and more. What Is […]

DAA 101: A Flexible Approach to Better, Faster Cable Networks
January 13, 2021
This month, we’d like to share information about Distributed Access Architecture (DAA) and how cable operators are using it to build the 10G networks of the future. In our previous posts about DOCSIS® and Coherent Optics technologies, we touched on some of the components of the cable hybrid fiber-coax (HFC) network, such as the headend and […]

A “101” on DOCSIS® Technology: The Heart of Cable Broadband
October 14, 2020
Welcome to the first installment of our CableLabs 101 series about a suite of breakthrough technologies that are instrumental in the path toward the cable industry’s 10G vision—a new era of connectivity that will revolutionize the way we live, work, learn and play. These technologies work together to further expand the capabilities of cable’s hybrid […]

CableLabs Releases DOCSIS® Simulation Model
September 10, 2020
When it comes to technology innovation, one of the most powerful tools in an engineer’s toolbox is the ability to rapidly test hypotheses through simulations. Simulation frameworks are used in nearly all engineering disciplines as a way to understand complex system behaviors that would be difficult to predict analytically. Simulations also allow the researcher to control variables, explore a wide range […]

The Cable Security Experience
August 31, 2020
We’ve all adjusted the ways we work and play and socialize in response to COVID. This has increased awareness that our broadband networks are critical – and they need to be secure. The cable industry has long focused on delivering best-in-class network security and we continue to innovate as we move on towards a 10G […]

10G Integrity: The DOCSIS® 4.0 Specification and Its New Authentication and Authorization Framework
May 28, 2020
One of the pillars of the 10G platform is security. Simplicity, integrity, confidentiality and availability are all different aspects of Cable’s 10G security platform. In this work, we want to talk about the integrity (authentication) enhancements, that have been developing for the next generation of DOCSIS® networks, and how they update the security profiles of […]

CoMP over DOCSIS: Femtocells in the Age of vRAN
September 12, 2019
As promised in the last couple blogs discussing DOCSIS based femtocells, we’ve saved the best for last. So far in the series, we’ve made the case for femtocells over DOCSIS networks and laid out the total cost of ownership (TCO) benefits of this deployment model. In this final blog post, I’ll share the results of […]

Enabling 5G with 10G Low Latency Xhaul (LLX) Over DOCSIS® Technology
September 10, 2019
I am a GenXer, and I am addicted to my iPhone. But it’s not just me, today’s consumers, millennials and baby boomers and everyone in between, are increasingly spending more and more time on their mobile devices. Have you ever wondered what happens to your traffic when you interact with your iPhone or Android devices? […]

CableLabs Low Latency DOCSIS® Technology Launches 10G Broadband into a New Era of Rapid Communication
September 5, 2019
Remember the last time you waited (and waited) for a page to load? Or when you “died” on a virtual battlefield because your connection couldn’t catch up with your heroic ambitions? Many internet users chalk those moments up to insufficient bandwidth, not realizing that latency is to blame. Bandwidth and latency are two very different […]
