Here is an abstract of a study I have just completed. Enjoy.
Optical Revolution Increases Obsolescence of Legacy Carrier Networks
Highly Efficient Layer One and Two Optical Networks Will Spell End of
the Road for ATT, Sprint & MCI in Their Current Form
Intelligent Acquisition Could Lead to Quick Write Offs of Obsolete Equipment
& Result in Modernization of "Telco" Infrastructure
An examination of the infrastructure of the Leading optical research
networks (SURFnet 6, CA*Net4, and TransLight) shows that we may well
be headed towards optical networks owned, built, and operated by
enterprises and other large entities that are sources of, and/or,
sinks for data, with the public Internet and carrier backbone
networks merely acting as inter-connecting vehicles for private bit
carriage.
We examine the emergence of new enterprise-owned and -operated
networks. These will be composed of hybrid networks that, for certain
Quality of Service and security-mandated applications set up
lightpaths, when needed, and then tear them down. Best-effort Layer 3
IP services for email and web browsing will utilize a separate
allocation of bandwidth elsewhere within the optical spectrum of
physical glass. This new enterprise-owned optical network is likely
to be one that could switch lightpaths back and forth on an as-needed
basis sending payloads over dedicated lightpaths where appropriate
and needed, while best-effort routing continues to function on its
own over intranet or Internet routes, thus filling in the gaps
between highly mission-critical and business-as-usual applications.
For independent verification of our basic conclusions see Dark fiber:
Businesses see the light.
