This driver subsided somewhat after a few years. The abundant capital (as well as
some market hype) of the telecom bubble diminished the value of integration and favored
a ???green field??? approach. Carriers had the money to build new separate networks,
so they built them. In addition, because these networks were relatively small, they did
not require large-scale operations systems, and so this ???green field??? approach allowed
serviced providers to circumvent the costs and complexities of integrating these services
into their existing OSS environment.
SONET/MSPP 309
Recently, however, EoS has returned to favor for two reasons. The first reason is that
the cost pendulum has swung back to favor EoS solutions. Post-telecom bubble capital
budgets are looking to squeeze more revenue out of the existing infrastructure, and
once again they value integration. While some professed the death of SONET during
the telecom bubble, SONET technology instead emerged with new vigor??”energized by
a new set of data-aware standards (e.g., GFP, VCAT, and LCAS) and equipment vendors
(both old and new) who packaged this technology in aggressive physical designs
and at significantly lower price points.
