We’ve talked about convergence for some time now. It’s been one of the most popular buzz words for our industry over the past decade and even spawned a few tradeshows of the same name to capitalize on the trend. First, it referred to networks, with some of the largest service providers in the world bringing together dozens of service-specific networks to a single IP Next Generation Network. (Come on now, you can’t deny IP is cool when it can do that!)
Now with a single platform, providers were able to more cost-effectively expand their offers to include those of other segments – the converged service provider could grow by not just offering, say traditional voice but move into video as well. Cable companies moved into voice, and just about everyone wanted a piece of the mobility gold rush.
Then, once that industry evolution gained traction, convergence was largely used in reference to services. New offerings such as Cisco TelePresence and others were no longer just a voice service, a video service, or a data service – but in actuality all three at the same time. This blended offer by a provider the worked against our nicely defined industry segmentation of cable, mobile, wireline providers, and led to an increased focus on converged technology of which Cisco spend quite literally billions of dollars each year to develop.
Converged platforms such as the ASR 1000 eliminated the need to have a half dozen different platforms doing separate functions and, instead, allowed a single platform to do them all at once, in a form factor only a few inches high.
Lately, the convergence theme is getting more and more buzz around devices. The iPhone gets credit for much of that, because after all, “there is an app for that” tagline does ring true. My phone now doesn’t just give me an ability to do email or rudimentary web surfing but allows me to track flights/listen to my music/find restaurants/occupy the attention of my bored 4 year old in the back seat of our car…..and it makes calls. Quite a bit of value.
In other words, transitioning more traffic to IP doesn’t mean building entirely new infrastructure. Rather, it means augmenting one of the several distribution mechanisms operators already employ, to carry video.
Cisco is a big part of the traditional and IP-based equipment foundation used by cable providers, and we have been there supporting our cable partners through analog television, standard definition digital television, and HDTV. IP is but another chapter in the video timeline.
John Chapman, Cisco Fellow and Chief Architect, discusses the viability of DOCSIS 3.0 versus all-fiber implementations, in this Part 2 interview from the floor of The Cable Show in Los Angeles.
What’s a better roadmap: DOCSIS or all-fiber? It’s a complicated debate. Our view is that the wide-ranging cable modem specification known as DOCSIS will continue to be foundational to advanced IP services.
Ultimately, the progression goes like this: Today’s DOCSIS-based cable modems are capable of 10’s of megabits per second (Mbps), in residential broadband services. DOCSIS 3.0 expands that range to hundreds of Mbps. Laboratory experimentation at Cisco suggests that a Gigabit per second DOCSIS offering is entirely feasible.
Since my last posting on Real Time Services, I have been thinking about the Internet being at an inflection point, specifically, the impact to sustainable architecture development due to content distribution that is relevant for consumers. Recall, from the April blog post that characterizing “real time” could be in the form of video, telepresence, voice, on-line games as examples, where mitigating latency is a must e.g. between clients-servers; agreement on what the optimal communications protocol should be and so on in order to deliver these services as expected by the consumer.
No doubt that managing the user experience is pivotal for customer retention.
As we shift the discussion to cloud computing, what are the implications to “cloud management,” to SLA management and so on? Let’s not forget the implications to security.
Hi again! Following last week’s post I thought it was worth a quick update. We actively follow cloud commentators on the web/twitter/social net and were pleased to see Cisco being mentioned in the cloud computing space.
TechTarget published its list of Top Cloud Computing Leaders last week – and Cisco’s own Chris Hoff was mentioned in this list along with the likes of Larry Ellison, Marc Benioff, Vivek Kundra and others. Chris is focused on our cloud strategy, works on the CloudAudit project and also writes on his blog and tweets prolifically on cloud computing related issues.
The list also mentions AT&T’s Joe Weinman. Joe is also a prolific blogger and has done much to demonstrate how cloud computing creates value on his Cloudonomics blog.
