Optical Foundations for Video Transport Networks
|
|
The impact of IPTV and other broadband multimedia services on service provider backbones will be enormous. Driven by changes in consumer viewing practices, even the very nature of the traffic will change over time. Service providers should deploy optical wavelength networking deep into the access network, and only undertake service layer processing when it adds value.

ROADMs Offer Massive Scalability for VOD Transport Networks
|
|
The higher capacity and lower cost of GigE ports, combined with the wide availability of Layer 2 Ethernet switches and Layer 3 routers to perform IP switching and aggregation functions have made IP the leading protocol for VOD networks, which is a major change for most cable networks. The key to the success of any VOD service is cost effective transport of hundreds to thousands of VOD streams over the core network. As the popularity of VOD services grows, the number of VOD output streams could become very large.

Packet technology for “Telco TV” Service Providers
|
|
It's not just about having the right technology but making sure the business case stacks up. Marlis Humphrey, Chairman of the Board for The ATM Forum, takes a look at how video delivery over packet networks and the plain old telephone line is now turning from a concept to a commercial proposition.

Advice to Telcos: Leapfrog the MSOs with VOD over the Global IP Backbone
|
|
The big opportunity for telcos is that by using IP to transport VOD to consumers over the last mile, they can play into their strength in nationwide IP backbones. Here is some practical advice: play to your strengths as a data provider by delivering video as an on-demand service. Partner with a satellite operator for broadcast services. Get access to your own content over time by leveraging nationwide and global IP backbones.

Packet-based MSPPs Offer Transport Option for Triple Play Networks
|
|
Packet-based multi-service provisioning platforms (MSPPs) offer a highly scalable, converged transport solution supporting the QoS metrics required to offer high-bandwidth video services along with voice and data.

Video Transport For Profitable Triple Play Networks
|
|
The key to success is the ability to build a network with low CAPEX and OPEX, preferably using a pay-as-you-grow model. One area on the network that often does not get the requisite attention is the transport between head-end and the last mile equipment (DSLAM, NGDLC, Ethernet switch or PON).

IP: The best way to deliver video over DSL
|
|
New technologies that build on the use of copper pairs have made it possible to deliver video without installing fiber all the way to a consumer's home. Combining IP with DSL is making cost-effective delivery of video to the home a real possibility, and it is a better choice than ATM.

Delivering Video Services Over the Evolving Telco Network
|
|
The technical challenge for telcos in offering the triple play lies on the video side, in finding the bandwidth to deliver video and integrating video delivery with the voice and data delivery platforms. WDM access transport rings, when implemented with optical add/drop multiplexers (OADM) to feed each DLC RT, offer low cost, high efficiency and reliability, simplified bandwidth management, and flexible service support.
