Traffic Engineering in a Fiber Deep Gigabit World

The introduction of Gbps service is dramatically changing cable broadband. Many new innovations are finding their way into cable operators’ plants and many others are on the way. With DOCSIS® 3.1 deployments well underway and DOCSIS Full Duplex (FDX) on the horizon, operators have the promise of symmetric Gigabit services. At the same time, some operators are starting their migration to fiber deep networks while others are looking at Distributed Access Architectures (DAA) such as Remote PHY. All of this will have significant impact on the way operators manage their traffic engineering and network capacity planning.

During SCTE•ISBE Cable-Tec Expo® 2017, at the session, “Traffic Engineering Optimization II,” I’ll be discussing the ramifications of these issues and the significant impact they will have on the way operators manage their traffic engineering and network capacity planning. Attendees at this session will also hear from Jeff Finkelstein, Executive Director of Advanced Technology, Cox, and Dr. Claudio Righetti, Chief Scientist & Security, Cablevision S.A. Argentina.

As an industry, we need to re-evaluate and update our models, starting with an intimate understanding of customer bandwidth behavior. I will discuss our recent research in this area and show interesting results from live plants. For example, we have seen an extremely wide range in capacity utilization between different customers, even within the same service tier. I will also highlight the impact on Service Group (SG) performance, This deep understanding of customer bandwidth behavior then allowed us to develop a more QoE centric traffic engineering model that operators can use to guarantee user satisfaction.

Join us on Wednesday, October 18th at 10:45am MT in room 205/207.

What’s Next? Opportunities in Wi-Fi® with 60 GHz

Devices using Wi-Fi® for data communication encompass every area of technology, and consumers expect to be able to check the weather, stream video, and see who just rang the doorbell, all using almost ubiquitous Wi-Fi coverage. In the future, new bandwidth-demanding applications will include virtual and augmented reality programming.

At SCTE•ISBE Cable-Tec Expo® 2017, I’ll be speaking at the session, “Checking the Signal: What’s Next in Wi-Fi?” where we’ll explore the latest in home Wi-Fi technologies and how they interact with licensed spectrum. I’ll be presenting an overview of 60 GHz and WiGig, also known as 802.11ad, and compare testing results with simulations.

It’s an opportune time to discuss 60 GHz wireless since Wi-Fi in the 2.4 and 5 GHz bands is struggling with congestion in many environments, such as the outdoors, MDUs, and shared business offices. The 60 GHz band offers a wide bandwidth with little interference from other sources. It’s already in its second generation with transmitters and receivers that are more reliable due to improved multipath handling and better antenna arrays. That’s unlike the early 11ad/Wi-Gig/60 GHz systems, which have real performance issues – cutting out when anything went between the transmit and receive locations.

My presentation and white paper, co-authored with Charles Cheevers, ARRIS CTO of Customer Premises Equipment biz, also covers the upcoming, still in progress IEEE revision called 11ay. And it highlights some new features that will enable outdoor use cases for this versatile technology. When researching the topic, we discovered that installing 60 GHz Wi-Fi in the corner of the room gave the best coverage as opposed to “normal” Wi-Fi, which performs best in the center of a room.

I’ll be discussing these findings and more on October, 17th at 2:00 pm MT in room 102/104/106 at the Colorado Convention Center. I hope to see you there.
