CDN / Existing Model
Existing Model:
 Unicast
 Cache
Akamai
> 140 000 servers
> 1200 Networks/ISP
Peak Traffic > 21 Tbps
IaaS
PaaS
SaaS
(≈ 9 Millions HD streams 720P/H264/2,5Mbps)
Tomorrow?
2,5 B users * 10 Mbps = 25 Pbps = 25 000 Tbps ( X 1 000 !)

Vast majority of OTT traffic today is unicast,
Multicast is typically enabled within a
network.
Usage:
 Live events
(sports, news, prime time)
 VOD Exclusivity Launch?
Approach:
 Specific telco agreement
 Platform software upgrade

HTTP/UDP
protocol
Demo with Qualcomm #CES2014 : Smart Gateway
Ability to define policies to proactively push content in a local cache
Usage:
 Subscribed video channel
 Hot tail / Popular content
Approach:
 Gateways, but also game consoles, set-top-boxes, Blu-ray players,

PEER ASSISTED DELIVERY
Intelligent
Prepositioning
Peer
Assisted
Delivery
HTTP/UDP
protocol
Get video from your peers instead of a server
Efficient architecture for live and popular VOD content
Usage:
 Todays adaptive segmented formats (HLS, HDS, Smooth, DASH) lend
themselves nice to peer assisted delivery
Approach:
 Large Experience with NetSession
 Software embedded into the devices
“Turn consumer electronics into video nodes”(5)
 WebRTC opens up the ability for installation-free p2p solutions
