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.

The SCTE IP Challenge has 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 »

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 »

Project Illustrates How Software Defined Network (SDN) and Network Functions Virtualization (NFV) Work in Concert to Enhance How Networks are Designed, Operated, and Monetized
Last week, I blogged about some joint research with Cox Communications related to our Evolved Services Platform (ESP) and NFV efforts. Another collaborative took place at the Society of Cable Telecommunications Engineers (SCTE) at their Cable-Tec Expo 14 event in Denver.
Loukas Paraschis, a Technology Solutions Architect at Cisco, co-wrote a paper (entitled SDN and NFV in Business Services) with Mazen Khaddam, Principal Lead Network Architect at Cox Atlanta.
The paper provides a comprehensive summary of Cisco’s SDN, NFV, and open source vision with the Cisco Evolved Services Platform (ESP). It specifically validates the service provider’s need for solutions that provide desired business outcomes for applications running across multiple domains (such as WAN and data center), and provides detailed use cases for the WAN Automation Engine (WAE).

This week, we and 10,000 or so hard-core engineering colleagues within the cable industry descend upon the city once known as the cable capital of the world — Denver, Colorado — and, like it’s been since the earliest days of the Society of Cable Telecommunications Engineers’ annual Cable-Tec Expo, a trending topic, now and forever, is bandwidth.
The reasons why are obvious, but indulge me a brief recap: Consumer usage of broadband grows at an compound annual rate of 50% or more, ever since about 2009, when Netflix began streaming video, in addition to mailing DVDs. Add to that the sheer number of video-capable, IP-connected screens we all use, and the fact that video itself is only scheduled to get bigger (we’re looking at you 4K), and it’s easy to envision why it’s a considerable challenge to keep the cable infrastructure updated, and capable of ever-increasing carrying capacities.
Here in Denver, we are focused on this challenge. Big picture, we are “transforming” cable access from a DOCSIS focus, to integrate DOCSIS with service provider WiFi, PON & FTTx, and MetroE into a single, easily- managed portfolio, which only Cisco can deliver. Doubleclicking on the DOCSIS pillar alone, we are taking the CMTS architecture and redefining it to deliver far more bandwidth, for far less cost. We see two technologies that stand out: Read More »
