What is Driving this Incredible Growth?

THE NEXT THREE YEARS:

• Over The Top & MSO-Managed IP Video: More Sessions at higher resolution… Unicast video replacing Broadcast

• IoT: Upstream Transmissions of many surveillance IP video streams per home

• The ‘Simulcast Bubble’: Simultaneous Transmissions of TV channels in QAM and IP video during the IP video transition

• Service ‘Snappiness’: Desire for rapid response times

• Marketing Pressures: The need to respond to higher PON bandwidth offerings

2x1080i60 = 18 Mbps @MPEG4

2x4Kp60 = 40 Mbps @HEVC

to be +500Mbps

The Million Dollar Question

• “How much bandwidth capacity is needed to provide good QoE to the subscribers within a Service Group?”

• This question has been asked & re-asked with every generation of HSD on the DOCSIS plant – 1999: Web Browsing (Basic) – 2001: VoIP & D1.1 Service Flow QoE (Tmax & Priority) – 2003: Peer-to-peer (Napster) – 2006: OTT IP Video Streaming (YouTube) – 2008: D3.0 (Channel Bonding) – 2009 & 2011 & 2013: MSO-sourced IP Video (Multicast) – 2014: D3.1 Full-Spectrum & OFDM (4K Video) – 2016: 1 Gbps Downstreams (New Services w/ very high Tmax)

• Many Rule-of-Thumb formulae have been used to answer that question in the past… – BW Capacity > (Nsub)*(Tavg) – BW Capacity > 2*(Tmax) – BW Capacity > 3*(Tmax) – Perform Node Split when Avg BW > 0.7*(BW Capacity)

Nielsen's Law of Internet Bandwidth

Nielsen's Law of Internet bandwidth states that: a high-end user's connection speed grows by 50% per year

Internet Maximum Service Tier Offered (Tmax)

1 Gbps 2016-18

2 Gbps 2019-21

10 Gbps 2022-24

Downstream Tmax BW

• Downstream Tmax = 1 Gbps (2016-2018), 2 Gbps (2019-2021), 10 Gbps (2022-2024) • Upstream Tmax = 0.5 Gbps (2016-2018), 1 Gbps (2019-2021), 5 Gbps (2022-2024)

20 Gbps 2025-27

100 Gbps 2028-31

• US Tavg almost 100Kbps in 2017

• US Tavg CAGR below 20% – Doubling every ~4-5 years – For Network Capacity planning,

typically use 20% to double every 4 years

8

Recent MSO Avg BW Traffic Trends

• DS Tavg passes 1Mbps in 2017

• DS Tavg CAGR below 40% – Not quite doubling every

other year

Some Recent DS:US Average BW Ratio Trends…

• Today, Most MSOs DS:US Avg BW Ratios are in 8:1 to 16:1 range

• DS BW continues to grow faster than US, so those Ratios will continue to rise in the near future

• 10G DS x 5G US is the target BW

• 684 MHz US versus 42 or 85 MHz today

• The biggest change in FDX is the expanded upstream spectrum

• Optimized for Fiber Deep (Node+0) with DOCSIS Remote PHY Nodes

• Currently FDX is in a pre-standards state
