INTRODUCTION


INTRODUCTIONTHE NEEDS OF TOMORROW’S INTERNET


• Service package

• Catch-up TV service, free-of-charge (UK only)

• Online delivery via PC, iPod, iPad, Wii, PS3, mobile phone

• As a digital TV service from VirginMedia and BT Vision

• Launched Dec. 2007 and growing steadily

• Service grown by 81% since last year

• 116 million requests in Feb. 2011

• Average of 1.4 million users per day

• Severe network impact

• YouView will fuel further growth

Carriers rethinking network architectureDistributed BNG and CDN – embracing content delivery

INTRODUCTIONUK – BBC IPLAYER EFFECT


• Users love it

• $7.99/month for streaming only service

• Works on over 200 devices

• Excellent content navigation and discovery

• Large (and growing) catalog available for streaming

• Consuming a huge amount of bandwidth

• Accounts for 29% of peak downstream Internet traffic (Sandvine Spring 2011 traffic report)

• Increased from only 6% in Q3 2009

• Growth has become a meaningful cost problem

INTRODUCTIONUSA – THE “NETFLIX PROBLEM”

Carriers rethinking flat rate tariff schemesCarriers rethinking their IPTV service offerings


A LOOK INTOWIRELINE


• Overlay architecture - individual “service edge” per service

• Every service operates in its own “ecosystem”

• Architecture is suitable when services are operating completely independently

• BNG is dimensioned to scale for Internet access only

• Average of 100 kb/s per subscriber is a typical dimensioning figure

• Maximize number of subscribers per GE port (e.g., 10,000 subs per port)

• Model allows for centralized deployment

THE EXCITING WORLDOVERLAY ARCHITECTURE


IS OVERLAY ARCHITECTURE SUSTAINABLE?TOWARDS CONVERGED BNG

• Trend 1: Deliver typical TV content to Internet-connected terminals

• iPad/tablet/PC for TV/video streaming and superior content navigation

• Trend 2: Deliver online video services to connected TVs

• Both OTT and premium (off-net carrier IPTV) video services

• These new video services are delivered over the Internet path (BNG)

• Time to question the separation of video and Internet delivery

IS CENTRALIZING CONTENT SUSTAINABLE?TOWARDS A DISTRIBUTED BNG

• OTT unmanaged content continues to grow very significantly

• YouTube, Netflix, Hulu, BBC iPlayer

• Online managed content will further fuel this bandwidth explosion

• TV everywhere and multi-screen video delivery (e.g., iPad TV streaming)

• Will centralized content injection still be cost-efficient?

• Time to question the BNG and content injection location (CDN)!

THE ENGINGE BEHIND


ALCATEL-LUCENT OPENED THE 100G ERA

Alcatel-Lucent raises bar in optical transport with first commercially available single carrier 100G using ‘Next-Generation Coherent’ technology

Offering highest performance and longest transmission reach - Critical element in High Leverage Network™ architecture

Paris, June 9, 2010 — Alcatel-Lucent (Euronext Paris and NYSE: ALU) today continued its innovation in optical networking with the announcement of the first commercially available solution to carry a single carrier 100 gigabit per second (100G) on a wavelength through the innovative use of emerging ‘Next-Generation Coherent’ technology. With this announcement Alcatel-Lucent is moving the market into the commercial deployment era of 100G next generation coherent technology.

"That this is a commercial release, and not just talk about a product roadmap, is quite a surprise. Alcatel-Lucent must have stepped up its development cycle, and that's significant," "With this announcement, Alcatel-Lucent takes the leadership crown away and leaves Nortel in the position of playing catch-up to release a single carrier 100G systems" Sterling Perrin, Senior Analyst , Heavy Reading


10G conventional NRZ spectrum –suited to 50-GHz spaced systems

By using quadrature phase modulation, the spectrum is compressed. Adding polarization multiplexing gives a spectrum that can be used with legacy 50-GHz spaced filters and a signal that has excellent transmission characteristics

The 100G NRZ spectrum is not compatible with existing 50-GHz spaced networks

…And also has dreadful transmission performance

KEY TAKE AWAYS


� By 2015, the EPC (Evolved Packet Core) and BNG (Broadband Network Gateway) will be Fixed-Mobile Convergent and Virtualized

� Mobile network architectures are flattening (all-IP), under pressure to reduce the cost per bit

� Flat IP architectures will allow and even require moredecentralized gateways due to high Transactional load

� By 2015, bandwith increase will require the first comercial 400Gbe coherent interface

Thank you
