I have written some material that I think will be of interest to list
members. While layer three is great there is a whole new world
building out there at layer one and two with cheap user rolled
optical nets. This new world will I believe affect IP and IP routing
in important ways.
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.
