In this brief video discussion, Rob Polack, Senior Director of Cisco Video Center of Excellence, examines the challenges for cable operators as they shift more video traffic onto their IP plant.
In short, operators will face three distinct challenges in the transition. One is skill sets. As attendees of this week’s SCTE Cable-Tec Expo know well, this industry is at a pivot point. The volume of change – analog to digital, MPEG to IP, multicast to unicast – will create a serious appetite for IP-related training. Read More »

As is often discussed, mobile data and demand for high-bandwidth mobile applications is exploding. Additionally, the business and technical landscape is changing dramatically – expanding competition, shift in revenue streams, next gen broadband technology deployments, move to all-IP architecture. These forces require mobile operators to build networks in new, “smarter” ways in order to address profitability.
This topic was addressed by Ash Dahod, Cisco SVP/GM of the Mobile Internet Technology Group, at 4G World – check out this video.

People often ask how many 6 MHz channels it takes to do an IP video offering over cable. The answer, of course, is “it depends,” but let’s be more specific: MSOs can create an IP video offering with as few as four 6 MHz channels. With eight, they can create a partial replacement of the traditional linear and on-demand video product line. Sixteen 6 MHz channels afford a full replacement of what’s on the MPEG plant today.
If that sounds like a lot, think about it another way. Today’s 860 MHz cable plant contains about 125 channels, including analog and digital. Between two and four channels are currently used to handle both broadband and voice over IP (VoIP) traffic. Viewed through that prism, 16 channels perhaps don’t seem like so much!
How much bandwidth is really needed to deliver VoIP depends on the nature of the service offering. Offering a full simulcast of the linear lineup costs more in bandwidth – some networks are already carried in dedicated analog, standard definition, and high definition bandwidth. By contrast, offering VoD content in IP is a variation on switched digital video, itself a bandwidth saving mechanism.
John Chapman, Cisco Fellow and CTO of Cisco’s Access, Transport and Technology group,
talks candidly in this short video about what it takes, in bandwidth and QoS, to launch a video over IP service.

New 3G60 Broadband Processing Engine Enables Cable Operators to Cost-Effectively Move to All-IP Networks
The long-awaited 3G60 line card for the uBR10012 CMTS has finally arrived. Ever since Cisco first conceived this line card, many worldwide cable providers have been waiting for its debut with breathless anticipation. In my 22 years in the cable industry I can’t recall any other product with as much advance customer interest as this one.
Why is the 3G60 such a hot commodity? Because it finally brings the right combination of very high capacity and very low cost-per-port that enables operators to realistically deploy Video-over-DOCSIS (VDOC) service. And VDOC is the key to moving to a converged, all-IP network, which dramatically reduces both capital and operating costs and provides unprecedented flexibility to introduce new services quickly and efficiently.
The 3G60 provides up to 72 downstream ports and 60 upstream ports on a single line card, – over 3 times the density of any line card on the market today. Using the 3G60, a single uBR10012 can support up to 576 downstream and 480 upstream ports per chassis. In addition, starting from a minimal base system, all of the upstream and downstream ports on the 3G60 can be provisioned via software licensing, so customers can install the card and then only pay for the ports they use. The 3G60 supports DOCSIS® 3.0 downstream channel bonding of as few as 2 up to as many as 24 channels, which makes downstream speeds of over 900 megabits per second possible. Read More »

I am really excited about the MPLS Conference 2010 to be held in Washington D.C. next week.
Whilst we have a fantastic agenda of industry leaders who are scheduled to speak at the conference, Cisco in particular will be highly engaged starting with the Sunday, October 24th Tutorial on Mobile Packet Core with Azhar Sayeed, Cisco.
On Monday October 25th, Cisco’s Luyuan Fang will co-present with Nabil Bitar (Verizon) and Raymond Zhang (BT), on “MPLS-TP Deployment Scenarios and Design Considerations.”
I will present on “Network Enabled Cloud and Service Models.”
The day will end with a panel co-chaired by Dave McDysan (Verizon) and Deborah Brugnard (AT&T) that includes Cisco Distinguished Engineer, George Swallow to discuss MPLS-TP and Ethernet OAM, “Peaceful Co-Existence or Continuing Competition.”
