Content Delivery System for Personalized Video Networks November 9, 2006 Video & Content Networking Business Unit
The Need for a Video 2.0-Ready Network Traditional Sources Community Sources VIDBLOGS.com Video 1.0 • “Browse” based • Fixed and limited content • 1-way broadcast • Single device • One size fits all • Predictable usage patterns Video 2.0 • “Search” based • Unlimited content • Interactive / On Demand • Multiple devices • Personalized • Rapidly varying usage patterns Video 2.0 is a Consumer Driven Experience: WhatThey Want.WhenThey Want It.WhereThey Want It.HowThey 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
Linear On Demand Time Shifted Personalized Cisco Content Delivery System Vision Enables any content, any device, any location from a single, open delivery platform. Arroyo (Cable TV & IPTV) Cisco CDS TV Mobile Cisco (Internet Video) PC
Design Challenges Challenge Solution Scalable system that automatically distributes content across network Scale and manage volumes of on-demand content Unifiedplatform designed for multiple networks, device and content types Converged services: broadcast & on-demand; TV, PC and mobile Real-time data transfers: ingest and commence streaming anywhere in networkwithin 300 ms Enable real-time applications (time shifting, ad insertion) and unpredictable usage patterns Network and content resiliency with automated hitless failover Meet expectations for broadcast level service availability Manage as single fault-tolerant system, not device by device Operational overhead as network and services scale
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 Source: VOD Servers – Equations and Solutions Glen Hardin, Time Warner Cable Paul Sherer, Arroyo Video Solutions

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 Bandwidth Usage Vault Array Stream Array 1-5% 100% “Long Tail”
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
Flexible Topology for National / Regional Networks Catcher • Tiered Vault arrays enable distributed ingest & storage • Large, centrally managed content library serving multiple markets • Locally managed regional content (inc. ads) • Cost effective content distribution • Fewer points of ingest • Reduced bandwidth usage • Less management complexity NATIONALBACKBONE SUPER HEADEND REMOTE HEADEND METRONETWORK METRONETWORK
Non-Stop Availability Catcher • Resource pooling and load leveling • Storage and streaming resources allocated dynamically across available hardware based on real-time demand • Any server within an array can instantly 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
Architected for Cost Effectiveness • Software-focused architecture for flexibility and high feature velocity • Low CAPEX • Scalable, distributed storage library • Fewer head ends • Eliminates replication at each streaming node • No 1:1 box redundancy • Low OPEX • Operational simplicity • Virtualization technology - manage multiple servers as one • Efficient, automated content management - no pre-positioning required • Bandwidth usage typically 95%+ less thanother solutions • Auto failover eliminates service emergencies • In-service maintenance and upgrades
