Core Video System:Market Status

� From a core network perspective, there is scope for confusion with respect to requirements for video

Different types of video service providers and service offerings

Each type can span verticals

Different requirements and architectural options for different types of providers by vertical

Numerous technology choices for each architecture

Market Dynamics� Contribution – General move from ATM and SDH networks to IP / MPLS

� Secondary distribution

Cable MSOs

Mix IP and satellite distribution of broadcast content today

National satellite backbones moving to IP terrestrial backbones due to regulation

Convergence of IP data and IP video services

Wireline – Incumbents

Acceleration in IPTV deployments

Longer term focus on integration of disparate networks – convergence of IP data (business and residential) and IP video services on IP/MPLS backbone

Support for retail and wholesale (regulated and unregulated) services required

Wireline – Challengers

Similar considerations to incumbents, without the pressures of regulation, hence wholesale requirements less prevalent

� Next round of core/edge upgrades for many SPs will be influenced by support for video services

Video Service Requirements

� Among consumer video services, real-time streaming applications such as IPTV impose the most stringent network requirements.

� Video streaming is used both for “broadcasting” video channels, which is commonly delivered as IP multicast, and for VoD, which is delivered as IP unicast.

� Broadcast video has more stringent requirements than VoD on the core

With the general move to distributed VoD architectures, where VoD caches are located at the edge of the network, the core network is used for distribution of the content to the VoD caches in non-real time. This is essentially a file transfer capability, which has less stringent requirements on the core network than IPTV.
