Full Duplex DOCSIS 3.1 Amps Upstream Capabilities CableLabs today unveiled the Full Duplex DOCSIS 3.1 specification, bringing symmetric multi-gigabit services over existing hybrid fiber-coax (HFC) technology and increasing upstream capacity to cable operators. Under today's DOCSIS networks, operators must mix and match upstream and downstream traffic. But Full Duplex DOCSIS now enables operators to deliver symmetric services via concurrent transmissions in the same spectrum, without touching downstream capacity, wrote Belal Hamzeh, vice president of research and development for wireless technologies at CableLabs, in a blog. Full Duplex DOCSIS 3.1 is the next step up from the existing DOCSIS 3.1 spec, which can deliver up to 10 Gbit/s downstream, 1 Gbit/s upstream. This latest iteration offers up to ten times today's available DOCSIS upstream speeds, according to a CableLabs paper on Full Duplex DOCSIS. This allows operators to deploy future-ready networks in preparation for next-generation applications and uses, the organization wrote. "In the United States, more than 90% of households are connected to an HFC network, and consumers typically have higher download speeds than upload speeds," said Phil McKinney, president and CEO of CableLabs, in the blog. "By enabling Full Duplex DOCSIS, upstream and downstream traffic can flow at up to 10 Gbps concurrently, doubling the efficiency of spectrum use." That's increasingly important, as more subscribers need more powerful upstream speeds in a world of cloud, augmented and virtual reality, multi-player games, IP communications and user-generated content. For example, live video traffic will account for 13% of Internet video traffic by 2021, according to Cisco's report, "The Zettabyte Era: Trends and Analysis." Online gaming traffic is predicted to surge at a compound annual growth rate of 57% between 2016 and 2021, accounting for 4% of worldwide consumer Internet traffic in 2021 versus 1% in 2016, the study found. Of course, other communications service providers are not sitting idly by as cable's infrastructure standards advance. Technologies such as vectoring and Gfast also are making strides in speed, symmetry and latency. Related posts:
