• 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

• 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

• 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)!

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

� 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
