DOCSIS 3.1: Driving Cable to Software Defined Networking

Guest Blog by Igor Dayen, SP Product and Solutions Marketing


Optical transport has been transformed as integrated high-performance Digital Signal Processing has enabled vendors such as Cisco to squeeze more capacity at greater distances than ever before. Advanced modulation techniques and Forward Error Correction are now commonly deployed. Cisco NCS 2000 platform can drive up to 140 channels, ranging up to 200 Gbps each, with the ability to drive 100 Gbps channels to over 4000 km.

Now we’re seeing the same concept appear in the cable space as DOCIS 3.1 sets the stage for new levels of both HFC throughput and capacity optimization. Imagine being able to get an extra 20%-30% of bandwidth out of your existing cable plant without replacing it? DOCIS 3.1 promises to make this a reality.

Join the SCTE IP Challenge – Perspective from Last Year’s Winner, Jamie Griffin

The SCTE IP Challenge haIMG_9141 copys become an event that I look forward to each year. I have participated for 2 years now and plan to return for a third at this year’s Cable-Tec Expo in New Orleans. It’s a great opportunity to test your own skills, meet industry colleagues, and enjoy some friendly competition.

The SCTE Expo itself is a great show and always leaves me with a feeling of renewed enthusiasm. The show floor is a great place to identify new equipment or technologies that could have a meaningful impact on your system. However, for me, the technical workshops are the most important events. In these sessions you get to hear real world experiences from technical leaders in the field, learn from successful and less-than-successful technology deployments, and get a great sense of where the industry as a whole is headed for the coming year.

The IP Challenge itself begins several months before the SCTE Expo with two rounds of online qualifiers. The questions in the qualifying rounds can be difficult and often require some research. However, the challenge isn’t necessarily clearing the board, the toughest part is catching all the bonuses and tokens. By the end of a full week you can develop a Pavlovian response to any change in the all-important bonus box.

Although the questions at the finals are Read More »

Cisco cBR-8: Re-imagining CCAP with SDN

Guest Blog by Igor Dayen, SP Product and Solutions Marketing


In an age of agile service creation with a virtualized IT infrastructure, the delivery of services by cable operators is undergoing a transformation. Two key technologies that are fueling this change are Software Defined Networking (SDN) and Network Function Virtualization (NFV). In this blog, we will examine how SDN is transforming service delivery for cable operators.

SDN offers much promise to cable operators. It changes how networks are designed, operationalized, and monetized, making them far more agile and responsive to customers. In traditional switch and router system architectures, the control plane is implemented in software running on a general-purpose CPU and the data plane is implemented with specialized hardware such as an ASIC. What SDN does is remove the Read More »

Two are Better than One – cBR-8 and Connected Life Won CSI Awards

christelle-gental-e1410553620989Guest blog By Christelle Gental, SP Video Marketing Solutions Manager

So here we are, back in Amsterdam for IBC 2015. The first busy day was concluded with the prestigious CSI awards, a ceremony which was launched by the Cable and Satellite International team back in 2003. The idea behind it is to recognise and reward industry top technologies in cable, satellite, IPTV, telco , OTT and mobile TV. The program has now grown to 19 categories and this year, Cisco was proud to be short listed for 4 of these: Read More »

Building the Cable Access Network for the Next Decade

cBR-8 front-100pixel

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.
