Cisco cBR-8 Rises up to the DOCSIS 3.1 Challenge at SCTE (part 2)

Guest Blog by Igor Dayen, SP Product and Solutions Marketing

I am excited to continue the discussion that I started in my previous blog on SCTE Cal-Tec expo.

We brought two cBR-8 routers and we used one to run live data through it.   We used Ixia gear to generate video and data traffic. Hence we showed the convergence.

The picture below on the left shows how DOCSIS 3.1 spectrum is being modulated—there are 4096 QAM, while the picture in the middle shows one spectrum for DOCSIS 3.0 and two spectrums for DOCSIS 3.1. Overall, it has been very impressive to see what DOCSIS 3.1 will bring and that we are able to demonstrate DOCSIS 3.1 today.  We offered Read More »

Cisco cBR-8 Rises up to the DOCSIS 3.1 Challenge

Guest Blog by Igor Dayen, SP Product and Solutions Marketing

What do we need to know about New Orleans? It offers great Jazz, and Bourbon Street provides rich insight into New Orleans’ past, but we can’t overlook that it has been home this year to SCTE Cable-Tec Expo. SCTE is the cable telecommunications engineering show of the year. Nearly 10,000 attendees annually seize the opportunity to discover and learn first-hand about the latest in cable telecommunications technology, products and services. For more than 30 years the industry has relied on Cable-Tec Expo to provide the most energizing, technical knowledge exchange of the year.

New Orleans Convention Center opened its doors to the biggest cable show of the year.

The “welcome” signs made it very clear that all attendees were welcome to be here, share their knowledge and learn from the exhibitors.

ANGA 2014: Igniting Growth for Service Providers

mckeownBy Mike McKeown – Director of Business Development for Service Provider Video at Cisco, EMEAR

It may be a month of bank holidays in Europe, but there’s no standing still for the video industry in May. We’re proud to say that it started with an announcement from Synergy Research (at the end of April) that we are the leading provider of video technology solutions to the industry.

How, you might ask, do you follow that?

With two of the industry’s most prominent events – firstly NCTA’s the Cable Show in LA and now ANGACOM in Cologne.

As with every year, NCTA provided a platform for the US cable industry to demonstrate and discuss the latest trends affecting some of the world’s largest cable operators.

On May 20th through 22nd, we’ll undoubtedly be having similar discussions at ANGACOM, but with a specific focus on Read More »

HDX Blog Series #2: Scaling with Turbo Performance

Editor’s Note: This is the second of a four-part deep dive series into High Density Experience (HDX), Cisco’s latest solution suite designed for high density environments and next-generation wireless technologies. For more on Cisco HDX, visit  Read part 1 here

With any new technology comes a new set of obstacles to overcome.  802.11ac is no exception.  Last week we talked about CleanAir for 802.11ac and why spectrum intelligence still matters. Another challenge is scalability. In this post I will give you some details on new HDX feature, Turbo Performance, which allows the AP 3700 overcome common scaling issues to scale amazingly well.

What’s Different with 802.11ac?

802.11ac means higher data rates, which means more packets per second (PPS).  There are three reasons for more PPS with 11ac: wider channels, increased modulation and increased aggregation.  Channel width doubled to 80 MHz, modulation increased from 64 QAM to 256 QAM, and aggregation increased from 64k to 1MB!

With 802.11n, an AP might have had to push 30,000 1500 byte packets per second through the APs data plane. Today with 802.11ac that could now be 75,000+ PPS.  More PPS means more load on the APs CPU, so to really keep up with the demands of 802.11ac, we needed to go back to the drawing board.   Read More »

A Cisco CCAP Update for Cable Show 2013: Helping Cable Operators Double Down… and Quadruple Up!

Three years ago, when I blogged about the Cable Converged Access Platform (CCAP), current events involved whether it would be called “CMAP,” “CESAR,” or something else entirely. (So much clearer in hindsight!)

Last year, when I blogged about CCAP at The Cable Show, current events centered on phasing, and how to prepare plant and infrastructure for the unified QAMs of CCAP — while the gear itself was being architected and built.

For what was Phase 1, Read More »
