An Update On the Best Ever Bandwidth Balm: DOCSIS 3.1

Written By Todd McCrum, Director, Product Management, Cable Access business unit, Cisco

By now, the SCTE Cable-Tec Expo is in full swing, and, as (widely!) expected, the matter of DOCSIS 3.1 — the latest iteration of the Data Over Cable Service Interface Spec — is a front-of-mind topic for pretty much everyone here.

1

Why: Because it’s the next step, and a major one, for all multichannel video providers needing to stay ahead of the 50+ percent year-over-year growth in broadband consumption. (Which is everyone.) We’ve said it before, we’ll say it again: Nothing, in the history of consumable goods, has g Read More »

Cisco at the 2015 SCTE Cable-Tec Expo

It’s Expo Eve down here in New Orleans, where the Ernest N. Morial Convention Center will soon fill with the technology people of the cable and broadband industry. Us included!

Children in a museum

We’ve been planning for months for this year’s SCTE Cable-Tec Expo, and are appreciably stocked (I hope!) with all of the elements that multichannel video providers (MVPDs) need to satiate their capacity needs — and contribute to the industry’s overall industrial momentum.

If you’re not going, or not familiar with the cable/broadband industry’s biggest and most hard-core tech event — the short hand is that it’s all about Read More »

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 »
