• "Internet protocol networks are like Pac Man. Eventually they will eat everything.” – Hossein Eslambolchi, AT&T's CTO, 2003
• "Anyone who relies on the fact that they own a scarce distribu7on resource is going to face ten years of turmoil.” – Paul Sagan, chief execuHve of Akamai, 2007
• "If a customer likes it, it doesn't maIer what it does to your economics – it's going to happen.” – Jack Cassidy, CEO of CincinnaH Bell, 2008

Data Rates
• TwiWer: Negligible • Facebook: Tiny (except video) • Skype audio: 6-‐40 Kbps * • Ne[lix SD Video: 500, 1000 & 1500 Kbps ** • Ne[lix HD Video: 2600 & 3800 Kbps **

Latency Not Important
Latency is Important
ConversaHon, even with a voice mail system, requires low latency

Voice QoS
1. Dedicated wires = 20th century approach – Cable & FiOS use separate logical path today
2. Simple prioriHes – Mobile telephony (2G-‐ & 3G-‐specific approaches) – Enterprise IP-‐PBXs (via DiffServ or 802.1p)
3. Extra bandwidth, i.e. “headroom” – Vonage, etc. – Skype
Mobile download bandwidth

Voice on 4G
• LTE is all-‐IP: Voice services a work-‐in-‐progress 1. Fallback to 3G voice 2. Leverage IMS / “One voice” / VoLTE (not VoLGA)
• 4-‐6 years for widespread 4G voice services based on carrier-‐provided QoS
Over-‐the-‐Top • Video Social – Happening now – Game over
– Happening fast !
• Voice – Happening now – TransiHoning market-‐by-‐market, as bandwidth headroom becomes available.
– Over-‐the-‐top voice on 4G is a certainty
Over the Top is the Future of Communica7on
