The Need for a Video 2.0-Ready Network
Traditional Sources

Video 1.0
Video 2.0
 “Browse” based
 “Search” based
 Fixed and limited content
 Unlimited content
 1-way broadcast
 Interactive / On Demand
 Single device
 Multiple devices
 One size fits all
 Personalized
 Predictable usage patterns
 Rapidly varying usage patterns
Video 2.0 is a Consumer Driven Experience:
What They Want. When They Want It. Where They Want It. How They Want It.

Servicing the Empowered Consumer
 Consumers are increasingly demanding content on their
terms – any content, any time, any device, any place
 Service providers are evolving into “experience
providers”
Challenged to provide subscribers with a coherent,
integrated media experience across different networks and
devices
Opportunities for deep user engagement by delivering their
“Digital Life” – increased subscriber satisfaction, increased
ARPU, reduced churn
 Cisco’s Content Delivery System (CDS) is the platform to
accelerate these emerging opportunities

Design Challenges
Challenge
Solution
Scale and manage volumes of
on-demand content
Scalable system that
automatically distributes content
across network
Converged services: broadcast
& on-demand; TV, PC and
mobile
Unified platform designed for
multiple networks, device and
content types
Enable real-time applications
(time shifting, ad insertion) and
unpredictable usage patterns
Real-time data transfers: ingest
and commence streaming
anywhere in network within 300 ms
Meet expectations for
broadcast level service
availability
Network and content resiliency
with automated hitless failover
Operational overhead as
network and services scale
Manage as single fault-tolerant
system, not device by device

The Challenge of Scaling Content Delivery
 VoD subscriber growth is
pushing up stream count
 The variety of content available
– movies, TV shows, music and
educational video, HDTV – is
pushing up library storage
 As content libraries grow from
1,000’s of hours to 10,000’s of
hours …
 And as an operator’s
geographic footprint grows,
necessitating regionalization
and local content …
 The storage, distribution and
accessibility of the content
becomes critical for …
 Efficient, economic operation
and increased customer
experience and satisfaction

2nd Generation VoD Architecture
 Build a bigger box and
centralize at head end in
attempt to address scalability
issues
Physical limitations persist as
content library grows and
usage increases
Programming
HEAD END
 “Network enabled” via ASI >
GigE connectivity
 Requires lots of metro
bandwidth as stream count
grows
 Not optimized for real-time
services
Time shifting

Content Distribution Efficiency
via Hierarchical Network Cache
 Different types of storage deployed across the network
Minimizes total cost – storage, bandwidth, content management
Maximizes performance – unique content caching protocol
 Content from any Vault is instantly accessible to any Streamer
Streamers cache content based on actual viewer demand to reduce backbone traffic
Automatic content distribution – no replication or pre-positioning of content
No other architecture economically scales for long tail, nPVR & user-generated content

Extreme Scalability
 Vault arrays
Content and ingest capacity scale
linearly with number of Vault CDEs
Content added to a Vault is
immediately available to all
subscribers
 Streamer arrays
Stream count and cache size scales
by adding streamers to an array and
adding new arrays to the network
 Vault and Streamer array sizes
limited only by Ethernet switch
backplane capacity
 Adding CDEs is non-disruptive
Add capacity, locations, applications
without taking service off-line

Non-Stop Availability
 Resource pooling and load leveling
Storage and streaming resources
allocated dynamically across available
hardware based on real-time demand

assume the identity and state of
another

 Auto failover enables “hitless” recovery
Hardware outages do not impact
service – no more emergencies
No interruption of subscriber sessions
 Non-disruptive maintenance
Replace hardware, upgrade software,
add capacity or add applications without
taking down service
 Applies to any application
