Abstract
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.
