Abstract
In addition to providing complete background on Advanced Access Architectures
(AAAs), this report is going to focus on the progress to date of AAAs (or in
some cases the lack thereof), changes in architecture, and especially how we
are changing our forecasts (and why) for Advanced Access Architectures (AAAs)
development. It is also introducing for the first time extensive cost analysis
of the various forms of AAAs, and comprehensive traffic (bandwidth)
requirements analysis and forecasts affecting AAAs.
(Please note that we will use the terminology Advanced Access Architectures
(AAAs) throughout this report to refer to the collection of FTTx architectures
and their variations. We feel that this is more comprehensive than simply
FTTx.)
This report, more than any of our past five reports on the subject, will
focus on:
- Bandwidth requirements, and options for obtaining that bandwidth
- Costs of alternatives in AAAs
- Forecasts for the acceptance of AAAs by customers
- The impact of AAAs on legacy high-speed access systems (e.g., xDSL)
