A New Solution for the Timing and Scaling of DOCSIS IP Multicast Services

hanks

Bill Hanks, Director of Systems Engineering

Attendees of this week’s The Cable Show are hoping to catch an early glimpse of tomorrow’s evolution in TV and cable. Next Wednesday morning, ARRIS’s own Tom Cloonan, CTO Networks, will be moderating a session entitled “From CDNs to Streaming Clouds: Advanced Approaches for Video Delivery”. On this panel, Amit Eshet, ARRIS Fellow, will be presenting a paper entitled “Multicast as a Mandatory Stepping Stone for an IP Video Service to the Big Screen” and I will be presenting a paper on entitled “An Improvement Proposal for the Timing and Scaling of DOCSIS IP Multicast Services”.

In my talk, I will address an issue related to a key component of the IPTV evolution: efficient DOCSIS IP multicast delivery.

Consumers’ increasing multiscreen habits coupled with the growing adoption of the DOCSIS 3.0 protocol pose an imminent timing and scalability challenge to many DOCSIS-based IPTV systems—ranging from multicast processing power, membership messaging latency, and unicast bandwidth needs for fast-channel-change techniques.

My co-authors and I believe that the industry can mitigate this challenge by employing a DOCSIS® Multicast Carousel to enable the cable modem to make its own tuning and multicast forwarding decisions.

Our panel takes place Wednesday, April 30 at 8:00 am in Room 403B. We hope to see you there!

The 364 Days Behind Earth Day

On April 22nd, we take the opportunity to reflect on what we do for the Earth the other 364 days of the year.

We call our approach to energy efficiency “conservation through innovation.” It represents our constant pursuit of better consumer entertainment experiences with a minimal impact on our natural resources. In the past year, we’ve taken major strides to improve energy efficiency in our own organization and with our partners throughout the world.

In December, we announced that we joined the U.S. Department of Energy, the Natural Resources Defense Council (NRDC), the Consumer Electronics Association (CEA), the National Cable & Telecommunications Association (NCTA), and multiple industry associations and energy advocates to reduce set-top energy consumption up to 45 percent by 2017, to the tune of $1 billion in annual energy savings for U.S. consumers.

Earlier this month, we collaborated with Verizon to launch its new FiOS Quantum TV experience, based on the ARRIS VMS1100 media server and IPC1100 video client. The combo achieves a 20% reduction in energy consumption compared with other configurations.

Today, ARRIS is a leader in ENERGY STAR 3.0 qualified set-tops, with 19 in our current lineup. And, we’re working to ensure that our new devices meet the EPA’s latest guidelines for the ENERGY STAR Version 4.1 specification.

These are just a few of the ways that we’re improving energy efficiency throughout the year as we collaborate with world’s leading service providers to bring the next stage of innovation and conservation to their millions of subscribers.

Getting the Most out of Your DOCSIS 3.0 Network: Dynamic Load Balancing of Bonded Modems

Jeff Walker

Jeff Walker-Sr. Director, CMTS Product Marketing, ARRIS

We’re using more bandwidth than ever. And that amount is growing by nearly 50 percent per year.

The reason is that we’re streaming more content, on more devices, from more sources than ever – whether it’s movies on our tablets, TV on our smartphones, or files from the cloud.

With no slowdown in sight and new services coming onboard every year, cable providers face a unique challenge to meet tomorrow’s demands on today’s networks.

One answer is wideband DOCSIS 3.0 technology, using dynamic load balancing across available wideband channels.

This can be a nearly universal solution, because most cable providers in North America and many around the world have upgraded to DOCSIS 3.0 capable CMTS/CCAP networks, and because DOCSIS 3.0 devices – like cable modems and video gateways – are on track to constitute 90 percent of all worldwide cable CPE shipments in 2014.

DOCSIS 3.0 Channel Bonding

This widespread adoption of DOCSIS 3.0 network and CPE components enable significant bandwidth increases from technology called “channel bonding,” which combines multiple channels (downstream, upstream, or both) into one, providing multiplicative bandwidth gains resulting in speeds beyond 1 Gbps downstream and 300 Mbps upstream.

DOCSIS 3.0 Dynamic Loading

Optimizing bandwidth from DOCSIS 3.0 networks requires dynamically load balancing channel-bonded modems. These modems have a particular set of channels in which they can transmit and receive upstream and downstream data – Transmit Channel Set (TCS) and Receive Channel Set (RCS) respectively. Users’ bonded DOCSIS 3.0 cable modems often are spread across these channel sets.

Dynamic loading involves periodically checking and comparing the utilization of available channel sets and moving modems to alternative upstream or downstream channel sets with lighter loads.

Moving modems from one channel set to another falls under a function known as Dynamic Bonding Change (DBC), which performs the move in hitless (no loss of registration) operation to eliminate network interruption.

DOCSIS 3.0 Static Load Balancing

Static load balancing is an alternative to dynamic load balancing, but inferior for network optimization, as it involves the CMTS/CCAP assigning a bonded DOCSIS 3.0 cable modem to a TCS and RCS at the time of registration based on modem count vs. channel utilization.

The Path to DOCSIS 3.1

Dynamic load balancing of bonded cable modems allows a provider to stay ahead of exploding demand for both managed and OTT video over IP services.  And, the expansion and efficient use of the DOCSIS 3.0 channel bonding will also enable a smooth path to DOCSIS 3.1 and the ability to compete against fiber-deep initiatives by bonding together DOCSIS 3.0 and 3.1 channels.

Stay tuned for more on the migration path to DOCSIS 3.1…
