Today's focus: Metro Ethernet mesh balloon bursts at NFOEC

By Jim Duffy

Vendors advocating optical Ethernet and mesh topologies in the
metropolitan area did not do themselves any favors at last
week's National Fiber Optic Engineers Conference in Baltimore.

Presenters in two Wednesday sessions - Optical Ethernet and
Metro Networks - could not adequately field and answer tame
questions from attendees. They stammered, danced around and
offered vague, content-free replies to questions like:

* How and why would a service provider migrate from a revenue-
generating ring to a mesh?

* How does protection and restoration, which is understood in
rings, work in a mesh?

* What are the cost and service benefits of a Gigabit Ethernet
PON over cable and DSL, or even plain old telephone service? On
this topic specifically, a vendor was hard-pressed to
demonstrate how a Gigabit Ethernet PON offered any new service
beyond the $100 to $200 people pay monthly right now -
including yours truly - for local phone, cable and broadband
Internet access.

Also, a vendor proposing a hybrid Ethernet/SONET implementation
over a "Gigabit Packet Ring" - ostensibly a pre-standard of
the emerging IEEE 802.17 Resilient Packet Ring standard -
failed to provide specific economics of this approach vs. SONET
running data or Ethernet performing circuit emulation. The
vendor merely offered "expectations" that there's a "cost
penalty" in adapting TDM to packet and vice versa.

It seems the metropolitan optical Ethernet/mesh proponents did
more to convince service providers to retain their SONET rings
than they did to urge a migration to packet-optimized
architectures. They not only did service providers a disservice
by not doing their homework; but they also did their companies
a disservice by possibly delaying or even eliminating a
potential revenue stream.

Renowned industry consultant Tom Nolle says companies building
their business on Ethernet eventually becoming the service
provisioning infrastructure for the metropolitan-area network
will be dead in six months. With last week's NFOEC debacle, it
may be sooner.
