Comcast Announces World-First Test of 10G Modem Technology Capable of Delivering Multigigabit Speeds to Homes

Comcast today announced the successful test of a prototype 10G modem using the core technology that will deliver multigigabit speeds to tens of millions of homes. In a world-first lab test, a Full Duplex DOCSIS 4.0 system-on-chip (SoC) cable modem built by Broadcom delivered upload and download speeds faster than 4 gigabits per second (Gbps) powered by 10G network technology. Today's announcement is the latest in a series of 10G milestones from Comcast. In October 2021, the company announced a successful test of a complete 10G connection using a virtualized cable modem termination system (vCMTS) powered by DOCSIS 4.0 technology. That announcement followed major 10G milestone announcements in April 2021, of the first-ever live lab test of a 10G system-on-chip (SOC) and October 2020, of a trial delivering 1.25 gigabit-per-second (Gbps) upload and download speeds over a live production network using Network Function Virtualization (NFV) combined with the latest DOCSIS technology

A key component of 10G, DOCSIS 4.0 is an evolutionary leap forward in the ability to deliver multigigabit upload and download speeds over the connections already installed in hundreds of millions of homes worldwide. "The great strength of our smart network design is that we are able to exceed our customers' demands today, even as we continuously evolve to meet the needs of the future," said Charlie Herrin, President of Technology, Product, Experience at Comcast Cable. "As our 10G journey continues to accelerate, customers will reap the benefits of ever-increasing security, reliability, and speed."

ISPs Should Do More to Safeguard the Web: FCC Chairman

US Federal Communications Commission (FCC) chairman sought "smart, practical, voluntary solutions", without mandating his own, for internet service providers (ISPs) to fight online fraud and data theft. Chairman Julius Genachowski estimated that 8.4 million credit-card details are stolen online, each year. "If consumers lose trust in the Internet, this will suppress broadband adoption and online commerce and communication, and all the benefits that come with it," Genachowski said in a speech. The FCC feels ISPs can come up with solutions that prevent client PCs in the US from being forced into malicious botnets by hackers, without having to encroach upon users' privacy.

Genachowski urged ISPs to adopt DNSSEC, a system that ensures people accessing sensitive sites such as their banks' online transaction portals go to the right address, and not redirected to a fraudulent password phishing site. "To be effective, everyone who is a part of the Internet ecosystem must play a meaningful role in ensuring that private and government networks, and personal computers and devices are secured," said Comcast/NBCUniversal President Kyle McSlarrow in a blog posting. Comcast is one of America's biggest ISPs. This is an example of how threats to the sanctity of a productive internet can be defeated with highly-specific solutions that don't threaten privacy and freedoms, instead of broad-scoped legislations that potentially do.

World IPv6 Launch Solidifies Global Support for New Internet Protocol

Major Internet service providers (ISPs), home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6 for their products and services by 6 June 2012.

Organized by the Internet Society, and building on the successful one-day World IPv6 Day event held on 8 June 2011, World IPv6 Launch represents a major milestone in the global deployment of IPv6. As the successor to the current Internet Protocol, IPv4, IPv6 is critical to the Internet's continued growth as a platform for innovation and economic development.

Microsoft Sells All its Shares from Comcast

Microsoft has sold its stake in Comcast Corp., the largest cable television company, the second largest Internet service provider and the fourth largest telephone service provider in the United States. In a filing Friday with the Securities and Exchange Commission, Microsoft announced it no longer held any shares in Philadelphia-based Comcast. The exact date of the share sale was not given, neither who's now behind the wheel of Microsoft's 7.26% stake. Back in 2002, Microsoft bought 115 million shares of Comcast, and until the moment of its retirement from the company's board it owned 150.9 million Class A shares. Representatives of Microsoft and Comcast declined to comment on the share sale, but according to third party financial advisors Microsoft's Comcast shares could have been valued at as little as $1.97 billion or as much as $3.4 billion. The amount of money whatever it is now goes back to Microsoft. I guess in time of recession it's better to have your money under the pillow, rather than investing them in something.

Comcast Plans 100Mbit Internet Speed for Customers

Comcast Corporation says it is currently on track to offer speeds of over 100Mbps to 20 percent of its customers by the end of 2008. By the end of 2010, they hope to expand the product to most markets in the United States. Comcast Senior Vice President of Investor Relations, Marla Dooner, calls the speed 'very competitive' with Verizon FiOS.

Comast is the United State's second largest ISP and the largest cable television provider. Among cable operators, Comcast has been the most aggressive in deploying a wideband technology known as Docsis 3.0 in response to user demand for high definition video.

Intel, Google, Comcast, Time Warner Cable, and Bright House Networks Form New Company

Clearwire Corporation and Sprint Nextel Corporation today announced that they have entered into a definitive agreement to combine their next generation wireless broadband businesses to form a new wireless communications company. The new company, which will be named Clearwire, will be focused on expediting the deployment of the first nationwide mobile WiMAX network to provide a true mobile broadband experience for consumers, small businesses, medium and large enterprises, public safety organizations and educational institutions.

Comcast Actively Interferes With File Sharing Services

Comcast, one of the largest providers of cable television and internet in America, decided recently that they were fed up with the huge amount of file sharing traffic on their network, which was beginning to affect the speed of other users connections. And so, they've snuck a little code into their cable internet services. Subscribers of Comcast can download all the BitTorrent/P2P content that they desire without a problem. However, when they in turn try to upload it to other BitTorrent/P2P users, Comcast forbids the file transfer from completing. Whether this is done via hardware or software is unclear. Regardless, this certainly puts a damper on file sharing. While this does stop potential pirates in their tracks, an independent film maker or artist hoping to share their content via BitTorrent will have to find a different service provider to share their content on.

Comcast's Super Fast Cable Modem

Bonding together four cable lines, engineers at Cable Television Laboratories have developed a technology called 'DOCSIS 3.0' enabling transfer speeds of 150 megabits per second. Available in less than a couple of years, U.S cable provider Comcast will compete with Verizon's new FiOS service which delivers 50 megabits per second but offers nearly unlimited potential.
