DOCSIS

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 […]

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 […]

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 […]

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 […]

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? […]

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 […]

No doubt our cable industry has a unique culture of working and innovating together to solve technical issues. But there are best practices from other communities which we can build from; these practices inform how we can continue to develop toward more reliable services. By “reliable,” as it relates to service, I mean reliable, available, […]

The 10g platform is going to provide reliable service. As the cable industry embarks on the development of 10G services, there is a lot of work ahead, but we already have a strong foundation of experience and technology to build upon. The 10 Gbps goal is about performance. But it must come with low cost, […]

You may have noticed that CableLabs is focused on innovation. One of our goals is to be recognized as the leading industry innovation lab in the world but talking about our innovation can be a bit tricky. Our job is to deliver innovation for the worldwide cable industry, but we can’t really talk about what […]

In our recently published blog post, we demonstrated why indoor femtocells have reemerged as an attractive deployment model. In particular, indoor network densification has huge potential for converged cable/wireless operators who can leverage their existing Hybrid Fiber Coax (HFC) footprint to either backhaul from full-stack femtocells or fronthaul from virtual Radio Access Network (vRAN) remote […]
