New Report Defines Which Networking Architecture is Best as the TelcoTV Market Evolves.

DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c70492) has announced the addition of Networking Strategies for TelcoTV Services to their offering.

TelcoTV services will put an increasingly large load on the metro aggregation networks that connect the video headend systems in the middle of the metro network with the access systems that provide the access services to the subscribers. This report describes the technologies that are available along with strategies for applying them.

Video traffic will dominate these networks as more and more on demand and personalized services are added to them. The move from broadcast to video on demand to network PVR to personalized advertising will shift these networks from data transport networks to video transport networks.

This report finds that the current Layer 3 IP and Layer 2 Ethernet architectures work well in the initial phase when the TelcoTV is just starting. However, as on demand and personalized services come to dominate, it will be necessary to shift to a Layer 1 optical architecture in order to economically support the huge increase in video traffic that this change will require.

This report identifies the strengths and limitations of Layer 3 IP, Layer 2 Ethernet, and Layer 1 optical architectures. It also defines which architecture is best as TelcoTV service providers move from broadcast to personalized on demand services.

In particular, this report addresses:

- How the TelcoTV service offerings are evolving from broadcast to on demand to network PVR to personalized advertising.

- How this TelcoTV service evolution will fundamentally change the traffic mixes on networks that support TelcoTV services.

- Which network architecture TelcoTV service providers should select based on their individual situation.

- The Layer 3 IP TelcoTV network architectures offered by Cisco Systems and Juniper Networks.

- The Layer 2 Ethernet TelcoTV network architectures offered by Alcatel-Lucent, ECI, Nortel Networks, and Nokia Siemens Networks.

- The Layer 1 optical TelcoTV network architectures offered by Ciena, Net Insight, and Sun Microsystems.

This report should be used by network planners, system architects, and investors as they consider network strategies for TelcoTV services. It will guide their choices based on both technical and business requirements based on the services provided as well as business strategies. It discusses both the approaches that should be applied when a TelcoTV service is introduced as well as when it matures with a personalized set of services and a large base of viewers.

The increasing amounts of video traffic that is being generated by TelcoTV services will cause service providers to move from their current IP and Ethernet networks toward optical video transport networks. TelecomView's new report Networking Strategies for TelcoTV Services identifies why current networks for TelcoTV services will break down and be replaced by these optical networks.

"We found that there is a broad consensus that TelcoTV services will move toward on demand, personalized services," stated Ian Cox, Principal Analyst at TelecomView. "This trend will increase the amount of video traffic on TelcoTV networks to the point where it will account for nearly all of the traffic on them."

This report discusses the IP, Ethernet, and optical network architectures offered by nine leading systems companies. It identifies the advantages and limitations of each architecture and defines which approach is best based on the services offered and the popularity of the TelcoTV service. It concludes that while IP and Ethernet approaches work well during the startup phase, an optical approach will become the best as the service becomes more personalized and more popular.

"The TelcoTV service providers are just beginning to see the limitations of their current networking approaches," stated Bob Larribeau, Principal Analyst at TelecomView and author of the report. "As they confront the issues described in the report, they will exert significant pressure for more and better approaches to TelcoTV optical networks."

This 90-page report addresses these issues and provides the information and analysis that TelcoTV providers, system suppliers, and investors need to meet changing TelcoTV networking requirements.
