Comcast

My Comments

Comcast is now one of the first major Internet service providers in the USA to set up for full IPv6 operation for its residential and small-business Internet-service products. Here, they are operating this on a dual-stack arrangement with customers able to receive IPv4 and IPv6 addresses and connections.

This is to satisfy realities that are affecting Internet use such as a reduction of publically-available IPv4 addresses and the arrival of the “Internet Of Everything” concept where there will be many devices connected to networks both large and small. IPv6 also opens up newer network-management functionalities like Segment Routing and Service Function Chaining.

Here, they are also optimising the XFinity X1 and XFinity Voice product platforms for IPv6 as well as implementing IPv6 for all of networks associated with the NBC Universal digital-content properties.

If a Comcast subscriber is to benefit from IPv6, they would have to connect the cable modem to a router that supports IPv6 dual-stack functionality. In some cases, you may have to have the existing cable modem swapped out for a newer unit or have Comcast flash the existing unit with newer IPv6-ready firmware. When you set up your router’s IPv6 WAN/Internet options, you may find it best to let the router use the “auto-detect” options.

This could show up as a step in the right direction for IPv6 in the world’s largest and densest Internet-service market.

Comcast, Time Warner boost net speeds in Google Fiber city – COINCIDENCE? | The Register

My Comments

Regular readers will have noticed my comments about the lack of real competition in the US fixed broadband market thank you to very cosy deals arranged by incumbent cable-TV and telecommunications companies and various governments on a state and federal level.

Google have just rolled out their Google Fiber FTTP broadband service, known for offering headline data-transfer speeds of a gigabit each way, into Kansas City. Now Comcast and Time Warner Cable, for fear of hemorrhaging cable-broadband customers to Google, have upped their cable Internet service’s headline data-transfer speeds without charging their customers a single penny extra for the upgrade.

Issues have been raised about the pricing and customer-service behavior of cable-TV companies when they are faced with real competition beyond the DSL service offered by the incumbent telco. This has come in to play during discussions concerning the proposed merger between Comcast and Time-Warner Cable, as well as the issue of Net Neutrality.

As well, I would see the Google Fiber rollout as a boost for local government in Kansas City because the properties in the area that have Google Fiber past their doors become increasingly valuable to live in or do business there. It is a similar situation that has happened in various UK neighbourhoods where houses are assessed by prospective buyers on whether next-generation broadband is passing their doors or the property is connected to a next-generation broadband service.

Who knows what this means for other US cities who are pushing Google for their fibre-optic service?

Net Neutrality and competition are at risk of giving way to US big money

Guess Who’s Winning The Money Battle In The War On Net Neutrality | Gizmodo

My Comments

This recent article is showing how the US government is capitulating to Big Money, especially from AT&T, Verizon and Comcast, when it comes to Net Neutrality and, to some extent, competing service. Here, it also highlighted how FCC are pandering to big-business interests because the jobs with telcos and cable companies are becoming a popular destination for outgoing FCC Commissioners.

Why do I think of Internet-service competition in relationship to Net Neutrality? This is because when you have fewer Internet-service providers or telecommunications companies serving a particular market or providing a backbone service, you also have a greater risk of these companies selling privileged access to Internet service at very steep costs.

Previously, I had raised the issue of government departments that regulate telecommunications being independent of established telecommunications providers which brought around the idea of competitive Internet service in the UK and France. Here, I mentioned about these countries having cheaper or better-value Internet service because these government departments don’t curry favour with incumbent telecoms operators and there is oversight of the telecoms market by competition regulators and drew this comparison when I touched on Deutsche Telekom being “Drossel-kom” (“Throttle-kom”) in Germany because their telecoms regulator curried favour with this incumbent operator.

What I suspect that is happening now is that the US is effectively heading to a business climate for telecommunications, Internet service and pay-TV similar to the business climate for like services that existed in the 1970s before the Carterfone decision and the anti-trust rulings levelled against AT&T came about. This is where AT&T (Ma Bell) was able to get away with poor customer service and phone services that were of poor value for money because they were the only option for telephony. This is also shown up with repeated customer-satisfaction surveys in the US placing these companies at the worst for customer satisfaction.

Some public-interest foundations like Represent.Us and the Sunlight Foundation are targeting the issue of Big Money controlling American politics and an American could support these efforts if they want to restore real competition with their telecommunications services.

Comcast–the first US cable provider to roll out IPv6

Comcast shifts some customers to IPv6, promises it won’t hurt — Engadget

From the horse’s mouth

Comcast IPv6 Information Center

My comments

Comcast are rolling out a pilot deployment of IPv6-based Internet service. Here the customers will be those using a computer that is connected directly to a compatible DOCSIS 3.0 cable modem.

The computer will have to run Windows Vista or 7 for the Windows platform or MacOS X Lion for the Macintosh platform. This is because these operating systems are known to support a dual-stacked IPv4/IPv6 setup which the service will be based on. As well, these services will be provided with a unique full IPv6 address. Of course, Comcast will have 6to4 IP gateways in the network to bridge the IPv6 and IPv4 networks.

At the moment, there will be the rough edges through the deployment of this trial setup while the bugs are ironed out. A subsequent trial in the near future will then look at the use of home networks, but I would like to have this trial examine networks that are comprised of IPv4-only devices as well as dual-stack IPv4/IPv6 devices. This would also encompass access to legacy and IPv6 Internet services from both the legacy and the IPv6 devices.

Most likely this rollout will appeal and be targeted to some of the computer “geeks” who want to dabble in the latest setups. But I see it as a chance for Comcast, a mass-market cable-Internet provider, to put IPv6 through its paces before the full deployment commences. It also is an open chance for Comcast to put their findings about how their IPv6 deployment went to other cable-Internet providers who will be facing a requirement to roll up to this technology.

Cable TV now on the Skype video-conferencing bandwagon

Comcast brings Skype calls to TV | Total Telecom

My Comments

Previously, Samsung, LG and Panasonic have implemented a Skype videoconferencing endpoint in their Internet-enabled TVs for use with an optional Webcam. This was to allow users to have the ability to make videocalls with the ability to hear their correspondent from the TV’s speakers and see them on the TV screen.

Now Comcast, a major US cable-TV provider, has got in on the act by installing Skype on their new set-top boxes. But, typically, what will happen is that customers will have to purchase a special USB webcam through Comcast to enable the service. The backhaul for this service will be the Comcast cable-Internet infrastructure and the service will appeal to people who have Comcast also as their Internet service provider.

Could this open up the door for pay TV companies to enable their set-top boxes as Skype endpoints especially as they see themselves losing relevance in the Internet age? This is mainly due to the “cord-cutting” trend where people are downscaling or cancelling current pay-TV subscriptions or refusing to subscribe to pay-TV and use “over-the-top” Internet-delivered video-on-demand services.

On the other hand, this step, taken by set-top-box makers and cable-TV companies, could allow people who have existing TV equipment to make or take Skype calls on their favourite big-screen TVs. For satellite-based or terrestrial-based setups, it will require the use of a backhaul via the customer’s Internet service, which wouldn’t be difficult if the operator implements other Internet-based services like catch-up TV or view-on-demand. It will be interesting to see who else will roll this service in to their set-top box platforms even as TV manufacturers enable their sets for Internet TV.

It has therefore become the first time that Skype has become available in a popular set-top-box platform, especially delivered by a pay-TV provider rather than requiring the customer to buy a new set-top box for this function.
