Слайд 3SETTING THE CONTEXT


Слайд 4“The Internet”
(The “Peacock Map” of Internet autonomous systems, circa 1999)


Слайд 5 Personal Computers

Phone Networks

Information Goods


Слайд 6 ≈1.5 billion PCs
≈1.3 billion landlines


1.65 billion CDs

The World, Circa 2012


Слайд 7
The World, Circa Now
> 1.6 billion smartphones+tablets
7

billion mobile lines
Streaming > 50% of Net traffic

Слайд 8
Post-PC Devices
Converged Broadband Networks
The Cloud
The Next Internet


Слайд 9The PC is Dead


Слайд 10So is the PSTN!
U.S. Residential switched access lines
194 million in 2000


101 million 2012
% of U.S. Households with POTS
93% in 2003, 25% in 2013, and…

Слайд 11Not Just a U.S. Phenomenon

>50% of OECD countries experienced a drop

in PSTN access lines from 2009-11.
In 8 OECD countries, already <20 PSTN access lines per 100 inhabitants.

– OECD Communications Outlook 2013

Слайд 12Coming Next: Internet of Things


Слайд 13Cloud Platforms are the New Utilities


Слайд 14Infrastructure of the 21st Century


Слайд 15IMPLICATIONS FOR FIXED BROADBAND


Слайд 163
(Share of fixed connections still on dial-up in the OECD as

of 2011)

%

Broadband is Here


Слайд 17Why Go Beyond Broadband?
Convergence
Voice/video/data to IP
Fixed/mobile/nomadic
Applications
Streaming media
Real-time communications
Telework/telepresence
Cloud computing and storage
Financial

services
Internet of Things
Smart homes

Слайд 18OK, But Why FIXED Broadband?
Mobile still only 7% of traffic in

2017 (Cisco)
Fixed is complementary to mobile
Most “wireless” traffic quickly goes to fixed
WiFi offload estimated at 70% of smartphone data
Most recent data suggests per-device mobile data usage may be peaking
At least, until the wearable/IoT explosion!

Has to plug in somewhere!


Слайд 19From Here to Fibre
Only truly future-proof technology
The Good
GDP benefits of

ultrafast networks
Knock-on effects of “economics of abundance”
The Bad
Up-front capex costs very high
Heavily take-rate dependent
Municipal obstacles like ROW
Transit costs an issue in some areas
Business case uncertainties

Слайд 20…And The Confusing
All modern fixed broadband access systems incorporate some fiber
Key

is how far fiber is extended toward the end-user
Claimed speeds aren’t necessarily representative




Netflix USA Speed Index, January-May 2014


Слайд 21Big Variation in Fibre Adoption
OECD ranks by FTTP as % of

Broadband Subscriptions

OECD Average: 15.75% (June 2013)



Слайд 22Big Variation in Fibre Adoption
OECD ranks by FTTP as % of

Broadband Subscriptions

OECD Average: 15.75% (June 2013)



Слайд 23Cable Changes the Data Somewhat

OECD ranks by FTTP+Cable as % of

Broadband Subscriptions

Слайд 24APPROACHES TO NEXT-GENERATION FIXED BROADBAND


Слайд 25Architectural Choices
Fiber to the home vs. the node
Cost vs. capacity tradeoff
The

Australia example
May be multiple technologies deployed within countries
Esp. with municipal networks
Hierarchy by density (FTTH/VDSL2/VDSL/Wireless)
Path dependencies important
High DSL/cable adoption may actually slow fiber


Слайд 26Business/Regulatory Models
Role of incumbents vs. new entrants
Non-traditional entrants (Reggefiber, Google) important

in some countries
Scope of public funding or provision
Different models being used at the national, regional, and local level
Success stories (Stokab), failures (Provo, UT), and incompletes (Australia)
Requirements for open access or wholesale
Prevalent in most of the world except the U.S.
Wholesale model often chosen voluntarily

Слайд 27Vectoring and G.Fast
Potential game changers?
“Fiber-like” speeds at “DSL-like” costs
Challenges
May make unbundling

technical infeasible
Heavily dependent on loop lengths
Real-world performance and deployment pace lags
Still tops out well below fibre speeds

Слайд 28Israel Fibre Network
An important global test case
Israel Electric Corporation (IEC) deploying

a 1 Gbps wholesale network nationwide
First announced in 2011
Partnership with a group led by Sweden’s Viaeuropa
Service scheduled to begin this month, offered by retail providers (10 so far)
Plans to cover two thirds of the country by 2020, and the remainder by 2033
Bezeq/Hot investing in FTTH in response

Слайд 29KEY POLICY ISSUES


Слайд 30What’s the Goal?
End-user maximum download speed isn’t necessarily representative
Interconnection, transit, caching,

equipment matter
Full capacity not always available at consumer prices
Caps, tiers, usage-based prices also significant
Importance and meaning of ubiquity?
Technological neutrality may be impossible
Investment decisions today lock in particular configurations for many years.


Слайд 31What About Competition?
Virtually no business case to overbuild fiber, except urban

MDUs
Natural monopoly?
Will the cost dynamics change any time soon?
Unbundling may be restricted
E.g. with vectoring
Potentially removes a major regulatory tool in much of the world
Choose between next-gen broadband and competition?

Слайд 32Operators vs. Edge Providers


Слайд 33Already an Issue in the U.S.


Слайд 34Watch This Space Going Forward
ETNO Proposal for “sender pays” rule
Complicated arrangements
CDNs,

multiple end user fees, etc.
Data caps, freezones, usage charges also significant.
At high level, interests are aligned
Preconceived idea of cost “causation” not realistic.
Voluntary deals raise neutrality concerns
Compulsion skews competition/investment w/no guarantee of more infrastructure


Слайд 35Surveillance and Governance
Governments go where the information is
Information goes where the

users are
An ongoing governance challenge

Слайд 36CONCLUDING THOUGHTS


Слайд 37Ubiquity
Capacity & Robustness
Interconnection
Innovation
Data Integrity & Privacy

The Network Utility Agenda


Слайд 38These Questions Aren’t as New


Слайд 39“A new pronouncement by the regulatory agencies of a doctrine of

free interchange of signals across the boundaries of individual systems would be of tremendous technological benefit.”
-- Paul Baran, “Communication Policy Issues for the Coming Computer Utility”, May 1968
