Cisco Fellow talks to Telecom TV about 5G and Information Centric Networking

While at the NGMN Industry Conference in Frankfurt, Germany, the folks from Telecom TV interviewed Paul Polakos, Cisco Fellow. Paul is our CTO office lead for 5G research. During this interview, Paul talks about Cisco’s active work driving towards 5G technology. Cisco is active in both Research and Development and the various standards organizations that are focusing on 5G development (like 3GPP, NGMN, etc.). Cisco is also working with our customers to align strategies.

Mr. Polakos stresses that 5G is about diversity of uses cases and devices unlike what we have seen in all the previous generations (i.e. 3G, 4G).

Cisco is very interested in Information Centric Networking (ICN) as a possible solution Read More »

Building the Cable Access Network for the Next Decade

When I talk with service provider customers these days about their goals, it’s a very different conversation than in the past. It’s no longer just technology and procurement people in the room; more and more, the people launching the actual services are steering the discussion. And they don’t want to hear about all the complexity of what happens in the network, or focus on cable modem termination system (CMTS) speeds and feeds.

These customers are facing stiff competitive pressure to scale bandwidth many times more than what the current network supports. They’re looking to increase top-line revenues by launching new cloud-enabled services Read More »

Building the Cable Access Network for the Next Decade

When I talk with service provider customers these days about their goals, it’s a very different conversation than in the past. It’s no longer just technology and procurement people in the room; more and more, the people launching the actual services are steering the discussion. And they don’t want to hear about all the complexity of what happens in the network, or focus on cable modem termination system (CMTS) speeds and feeds.

These customers are facing stiff competitive pressure to scale bandwidth many times more than what the current network supports. They’re looking to increase top-line revenues by launching new cloud-enabled services for converged video and “Internet of Everything” (IoE) capabilities in the connected home. They’re preparing for DOCSIS3.1 and evolved Converged Cable Access Platform (CCAP), and they want to make it easier and less expensive to implement them. And they want to know what we’re doing to help them extend fiber deeper into the network, virtualize functions, and converge residential and business networks to lower costs.

This is a much more strategic discussion. And it’s one we’re anxious to have, because that’s exactly why we created the Cisco cBR-8 platform.

What’s “Evolved” About An “Evolved CCAP”?

By Todd McCrum, Director of Product Management, Cable Access Business Unit, Cisco

If you’re making the rounds at this week’s INTX, you’ve likely gotten wind of our flagship product announcement — the Gig-maker that is the cBR-8, as part of Cisco’s Evolved CCAP solution. Our categorization of it as an “Evolved CCAP” solution may need further defining. The answer requires a bit of background, starting with CCAP itself. It stands for “Converged Cable Access Platform,” where the “converged” part refers to a one-size-fits-all QAM modulation system that works for video, voice and data. Prior to CCAP, modulation was handled individually for video and data/voice products — I still remember the cable system GM who lamented that “every time I turn around, somebody’s sending me a request to buy more QAMs.” CCAP alleviates that concern.

What’s evolved about an evolved CCAP, and in particular, the cBR-8, can be characterized in three ways. First, the original CCAP spec (started about five years ago) covered a total of 64 6-MHz channels. They’re typically divvied up half and half: 32 channels for DOCSIS 3.0/broadband traffic, and 32 for MPEG-delivered, narrowcast video, like VOD. (Note: Not live or linear.) Subsequently, the DOCSIS specification itself evolved to 3.1, which substantially increases available bandwidth for IP-based services. As a result, and in our view, CCAP needed to develop in lockstep.

Evolved CCAP enables 100% convergence of all video types — narrowcast/VOD, sure, but also linear/MPEG, and any managed IP video tiers that might be entering the service mix. Plus enough room for both DOCSIS 3.0 and 3.1-based traffic. The reason I feel confident in saying that the cBR-8 is ahead of the marketplace on this one is that our competitors tend to use an off-the-shelf chassis, which puts a hard architectural limit on how many total serving area groups they can reach. Trying to wring more bandwidth, or reach more serving areas, becomes expensive with forklifts in that scenario.

Which brings me to the second characteristic of an evolved CCAP: Read More »

Getting Broadband Where It Needs to Be: Introducing the CBR-8

Here’s an industrially trending topic: Broadband speeds. We had the January 2013 FCC mandate for at least one Gigabit community in all 50 states by this year. We have Google’s continued Gigabit push, expected to roll into 18 more cities this year. The National Cable & Telecommunications Association (NCTA) is leading broadband expansion into 93% of U.S. cable homes, while driving initiatives to triple broadband speeds, and further the industry’s leadership and innovation in broadband.

This isn’t the easiest mandate, for service providers. Recall that broadband consumption continues to grow at 50% year-over-year.. And coming up fast are the things of the Internet of Everything, which put another multiplier on broadband consumption.

In short, and whether or not you believe Gigabit services are more “billboard speeds” right now, the Internet needs to go faster..and faster. That’s why you’ll be hearing so much from us this week at INTX about our new cBR-8 — the industry’s first platform with the speed and capacity to deliver (not just test!) 10Gbps DOCSIS 3.1 and capable of supporting scaled deployments of bouquets of DOCSIS 3.0, DOCSIS 3.1, and converged data/video services.

That’s tech-talk for super fast, available, and effective broadband — without the unpopular “forklift upgrade.” We designed the cBR-8 that way on purpose, with three sustaining project goals: 1) massive bandwidth, 2) delivered cost-effectively, to 3) enable our customers a rapid market-entry with reliably competitive broadband products.

Here’s what the cBR-8 brings to the broadband table: Read More »
