A fundamental enabler in connecting people around the globe, DOCSIS technology has empowered millions to live, work, learn and play. Since the days of the first DOCSIS 1.0 cable modems (CMs) almost 30 years ago, DOCSIS technology has continued to evolve, benefitting from a robust ecosystem of operators and vendors working together with CableLabs to […]

Network usage patterns have shifted in unprecedented ways in the last few months with vast swaths of the population staying at home. A substantial increase in network traffic has been observed from homes with people collaborating for work and children learning over the Internet with online school sessions and material. The access networks have seen […]

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 […]

Cable operators are broadly deploying DOCSIS 3.1 technology around the world. Operators in North America and Europe have announced gigabit service offerings that use the technology across their footprint. In this blog, I focus on techniques by which operators can boost the capacity and robustness of their existing DOCSIS 3.1 network. Introducing Toolsets for Optimizing […]

Full Duplex (FDX) DOCSIS® (now a part of DOCSIS 4.0 technology) is an update to DOCSIS 3.1 specifications that builds on the core Orthogonal Frequency Division Multiplexing (OFDM) technology. This additional set of features significantly increases upstream capacity and allows for the same spectrum to be used as downstream or upstream. The set of MAC […]

Open source software continues to make solid inroads in the world of network technology. There are various open source industry efforts which are becoming de-facto standards that are being adopted by operators and equipment manufacturers (Linux, Apache, OpenStack, Docker etc). Open source leads to free and quick proliferation of good ideas. Collaboration tackles tough problems […]

DOCSIS technology continues to extend the usefulness of the hybrid fiber coaxial network and increase its global adoption. Distributed Architectures for DOCSIS networks are emerging that provide significant scale advantages and flexible deployment options supporting for both DOCSIS 3.0 and DOCSIS 3.1 networks. Distributed DOCSIS deployments are beginning today in some markets based on the […]

DOCSIS® continues to prove its strength, longevity, and relevance as a worldwide access network technology. Last week, CableLabs issued the C-DOCSIS System Specification, completing the suite of specifications known as C-DOCSIS. Cable companies in China are choosing DOCSIS as one of the technologies for offering High-Speed Data and other IP services. CableLabs has new member […]
